Technically, wouldn’t the Atlantis DHD be more “fragile” as it was not intended to be exposed to the elements? Part of why ancient technology seems to never change over thousands of years is possibly because you have to balance ability and size with durability. The Ancients found the most durable way they knew to build things, but that limits how advanced or compact they can build something.
I believe the smaller crystals outside of the MCC pit might be for running the lights under each key on the DHD as well as receivers for puddle jumper sent commands. They could also stand to be power spike diminishers in the event the gate is receiving energy surges from the dialing gate.
Great episode Taylor! I absolutely love the design and look of the Pegasus Galaxy DHD. I thought it was a huge improvement over the standard one from SG-1. Anesthetic change they didn't need to do for Stargate Atlantis but they did and I liked it
Well I think from a film making point of view it was a different enough thing so that it was still a connection to SG1 but separate enough to be unique to SGA.
For as many times that the DHD is separated or damaged, I would have thought that the Ancients would put more of the important components of the DHD in the stargate itself, maybe even with a little key pad on the side, and have the separate DHD be there but not necessary to perform all of the tasks that require a DHD. Most important being stellar drift and power.
At the end of the day, the gates themselves are actually very simple devices; at least compared to the DHD. They act mostly as antennas to find each other and emitters to propagate wormholes between each other. Some other rudimentary circuitry must exist to receive DHD signals, display/indicate symbols, and in the MW gates, some rotary dial encoding if the address is known. However, the chief goal for the gates is durability. In order to maximize durability, functionality such as hatches that open and moving parts would want to be minimized overall. It’s interesting to note them, that the destiny gates seem to rely so much on moving parts. If they are truly the ‘oldest’ version, it would make sense that the newest gates, in Pegasus have no moving parts whatsoever.
We can see throughout the show how much SGC learned about DHD's and the gates. In the first few seasons, they dialed the gate simply by rotating the inner ring with motors. Later on, it is obvious the "manual" dialing is no longer used by Stargate Command. They obviously used O'Neill's blueprints to upgrade their dialing computer. I remember an episode where SG1 got stuck in some museum and Vala said they should request a naquadah generator and a laptop with a dialing program.
See the only Two Issue I've ever had with Stargate is with the Gates and their various DHDs. Namely with how the "Addressing works" and the actual precision required in plotting a course etc. For example the whole ideal behind the DHD and the references in SG1 etc. etc. is the gate system works like a telephone system. Meaning you "Dial" to go some where. If this was the case wouldn't the point of Origin be the first Symbol you dial not the last? or how about the 8th Chevron the so called Galaxy Area Code. What about the 9th Chevron the "Pass code" so to speak to get on Destiny? Even with current network packet transmission these codes are usually the first to be read so the packet can be not only sent to the correct destination but opened and read properly by that destination. Then we have the precision of the whole 6 points in space marked by star Constellations, that only works if you are within the visual bubble of those constellation once you exit them....yeah doesn't work anymore. More than likely why Atlantis and Destiny gates don't go with those style glyphs. Destiny makes it interesting by introducing an Ad-hoc method of scanning for gates much like wireless devices scan for access points. Ideally if this was the case a gate could then use the point of origin from other gates in the system to correctly depict its relative position etc. Which makes me think of another issue....if there are millions of gates in the system and only 39 or 36 glyphs on the gates themselves then gates wouldn't be able to be moved far from where they were originally located with out messing up major sections of the gate system.
It could be but with the 8th and 9th Chevrons it would make sense for it to be last, my guess is uniformity. You are first telling it where you want to go then from where and is only referenceable from the point of origin.
I know its been a while since I watched the shows, but didn't the puddle jumper some how connect to what ever DHD was closest, and just override those controls?
I'm guessing the whole reason that the force shield is disabled when the puddle jumper activates a gate is prevent some idiot in the gate room from cutting a jumper in half by activating the shield.
I think portable DHDs were common among those who knew how they work. Even the SGC had a DHD laptop w/power source for situations where a native DHD was not functioning.
Very thorough video, and very nice channel sir, keep this up. That's very good source of information, and considering the release dates, glad to see the SG fandom is still alive and kicking. One thing I always wondered, unless I missed something, is a possible connection between stellar drift and the dreaded P.O.O. that makes every SG fan jump to ceilings... What if simply, the POO is a "compiled" set of six symbols into one compressed shot that is built out of the gate's local position, calculated through the drift update, then hardwritten into the gate? Might sound silly, I know, this is just fan conjecture after all. It might explain how without a DHD, a gate's last updated POO eventually wears out over time, and other things.
I really dont think thats the case since POO symbols tend to be unique to each gate and the gate will still dial out even when moved to another planet. meaning however the POO symbol works its capable of updating its address on the go. although during apophis's invasion jackson said he used earth as a POO on the Ha'tak its not likely that the given gate had a symbol for eart, but honestly you could be right stargate isnt well know for its continuity as far as their tech explanations its usually what ever suits the plot at that moment
@@shaneebahera8566 Well, yeah. This entire idea revolves around a Stargate requiring to be within its DHD's range to keep its POO up to date. If the DHD is displaced ( ha'tak going to earth for example ), it will get new coordinates, being Earth in this case, and its gate would work as if it were Earth's gate all along. The design of the POO might look different but it'd still be inscribed with the most recent "YOU ARE HERE" data. But yeah, that last segment you wrote is so damn true. The biggest hole I could find on my own with this theory, after some time thinking of it, is that this would mean stellar drift was enough since 1928 when the Alpha gate was moved away from its DHD to render all addresses but Abydos & Heliopolis unavailable, not thousand of years as the series states...
@@shaneebahera8566 a P.O.O. is the encoded position of the dialer gate. Since in 3d space, you need an (x), a (y), and a (z) in order to have a position, it'd make sense that the gate being dialed would send it's own P.O.O. back to confirm and establish the wormhole.
I always thought it odd that the DHDs in the milkway, looked very Goa'uld in design, but the gates themselves looked Ancient. The DHDs in the jumpers and in the Pegasus galaxy were more Ancient looking. Any ideas as to why the stylistic change in the Milkyway for the DHDs?
@@KohuGaly All I am pointing out is to me, the DHDs look more like Goa'uld design on the outside, than the gates themselves, which look more ancient in design. The Pegasus galaxy Dhds look more like an ancient version of a Foa'uld design. I am not talking about function nor who built them, just the outter casing's stylistic representations.
There's no in-universe explanation, unfortunately. 😅 Though I'd argue that the disparity isn't that great not least of all in the light of the disparity between Pegasus & Milky Way gate.
Well the DHD's in Peagasus have the same black texture/design and I doubt that the Goa'uld had the power to reach that far out. And like someone else said, their tech is based heavily off the Ancients leading to similar dragons for some things
Nice summary, thank you. =) But one thing I'm still wondering about is how the safety protocols work. Are they in the DHD or in the Stargate itself? Because in the "Red Sky" episode, the earth dialing computer apparently also had some restrictions that haven't been set up by humans. I don't remember if they have actually downloaded the whole data from a DHD at some point, but if not, that protocol has to be in the Stargate itself. Also, there is a protocol preventing the wormhole going right through a sun, but not preventing accidental time travel involving solar flares, which I would assume could have been covered right there. Considering this happens twice in the show by sheer coincidence (SG1 "1969" and SGA "The Last Man"), it's hard to believe that the Ancients have never encountered this "glitch".
Great video, been watching a lot of your videos lately during my rewatch of SG-1. (I've seen seasons 1-8 of SG-1 and all of SG:Universe, but only a couple episodes of Atlantis. This rewatch i'm determined to finally get to the show everyone tells me is the best Stargate ever was.)
It's interesting that science-fiction physics constantly try to say worm holes will be a method of transportation but they have no idea what a wormhole would be, what it would consist of the closest they say might be a tornado but again nobody has offered what a real tornado is made of
most would be for the controls for the push buttons as they would require the info of all places each symbol could connect to as the amount of them is like impossible to just get right the first time and it would need to remember the other gates address to be able to connect at all
A great overview of the DHD, thanks. A quick question: how is the Point of Origin symbol identified on off-world DHDs? Too simple to say they always occupy the same position. 🤔
It's probable that the Ancients programed where the planet was located, then took account of spacial drift like they did with other Stargates. Other than that, I don't really know lol.
I'm glad you liked the video. I believe that they didn't care about that too much. That they assigned a symbol to each gate, mapped out the network and set it to auto correct. :)
There is another control panel in the pedestal which houses other components like the buffer. The buffer stores information of what happens with the gate in the last usage until someone puts a new address into the system or it degrades.
Well it does keep a list of addresses dialed recently. However, when it comes to storing patters of things that have come through the gate that is in the gate itself. Take Teal'c for example.
also, they werent really "cars", it was several heavy duty military trucks and jeeps, wouldnt be surprised if they found some generators in that warehouse as well
On power, I think a Stargate doesn't need a strong source of power, just enough stored power. I suspected that gates/DHDs absorb energy from the surroundings to enable dialing sequences to work. So, a single car battery running like a jumper would, after several minutes, charge a Stargate to successfully dial out. Portable dial devices (as seen in Continuum) would likely do the same...provide power if needed to dial the gate. A wormhole is limited to 38 minutes presumably because it's as long as this power charge sustains it. Whenever a limitless power source is attached, we've seen wormholes maintained indefinitely.
its explained in a few episodes they use manual dialing that the gate can draw power from the dhd or power source of either end of the wormhole so when they dial using trucks and jumper cables theonly needed enough energy to start the dialing process but not establish and maintain the wormhole
A Stargate by itself is fully capable of safe dialing. They have in built protocols to prevent such situations. They also have vast arrays of sensors and processing systems in built that it makes you wonder what the DHD itself is actually doing. The Destiny gates are a great example of being made using the most cheapest of materials but still having a good amount of sensors and processing not to mention storage for its raw data. On top of its secondary function of transporting people around. So far my suspicion has been that the Milky Way gates+ actually have remote neural interfaces built into them. For the purpose of control by more advanced races. My suggestion would be to consider DHD's an upgrade that was added after the Milky Way gates were built. They are far more programmable and updatable over the entire network. But most importantly, they allow lesser advanced races to use them no matter where they go. As for their true function? My guess is it has to do with viruses and monitoring of travellers. Along with the ability to create matter in large amounts. Although it wouldn't surprise me to learn that the ascended Ancients were using them to gain their power from. Which is probably less of an issue since they wouldn't have a clue its happening.
The DHD definitely is an upgrade I agree, and the gates do have some built in safety features. But take a look at the episode Red Sky the Asgard stated that if the humans had a DHD it would have prevented them from getting a lock that would have destroyed the planet.
Why am I just now finding this! Do u have any videos on the Jaffa symbols on there fore heads. Different types for what gods. Also I do believe the DHD had a huge red crystal for a power source. Love the video. Gonna check out your others.
the reason they cant use the shield is explained in the episode where they return and take out the replicators they say they cant raise the shield due to them not having control of the gate in other words the puddle jumpers have a built in iff that auto controls the shield this would be so if they needed to access the gate room but could not they could use the gate and a puddle jumper to do it as even in the past the ancients could of used hyperdrive to get to another gate and then send the jumper through the gate to gain access
I'm not sure if the Atlantis and puddle jumper DHDs are "better." The bulky DHD is clearly designed to withstand the elements. I wonder if the more compact units would fare so well if left outside. A DHD can be quite small if maintaining and repairing it isn't going to be a concern, otherwise you must over-engineer it to compensate for years of neglect and abuse.
if every gate needs a point of origin then surely the number of gates is limited to the number of symbols on the gate? the gate should have used something like each symbol for a different pulsar and using that to triangulate a destination, so no need for point of origin
My theory is that there is one slot on the DHD that's for the point of origin symbol. However, as the movie indicated that symbols on the gate differ based on location in the galaxy, you'd think addresses would really be messed up to calculate...UNLESS they ret-conned the symbols to be the same on all gates (as seen from Earth) and the sequence of entry could still produce thousands of possible destinations.
I think there are the same 36 symbols on all DHD's and one symbol differs between all of them representing the point of origin. Still, it is a big amount of gates to exist. If I'm not wrong the amount of address availiable in the Milky Way (39 symbols - point of origin = 38) 38*37*36*35*34*33=1987690320 possible address. And that's just the 6 symbol sequence XD.
@@gpcexplorer makes you wonder how the point of origin symbol works considering the gate can still be dialed out even when its not in its original location. when Jackson dialed from the the mother he say he used earth as a point of origin but its highly unlikely that the dhd for that gate had an earth symbol to use as point of origin
Very cool, Taylor!!! Now, we just need a video on "How Jack O'Nealls' mind works" Or is that something the Ancients would look at and say, "You're on your own guys! We're outta here!"
It was built after months of research through trial and error and a couple of supercomputers trying to figure out the input and outputs that Earth's technology at the time could understand. Once it was found out how to "control" it in a crude way, some changes were made. New programming (fast dialing mode), skipping dialing steps for getting a lock and after the 8th season of SG1 a major upgrade to software was made although it seems that most interfacing technology was kept in the same way. Power is supplied to the gate through a couple of inductors, possibly working like an RFID reader but with a much stronger power output to supply to the gate (as it can absorb any kind of energy, so in theory a strong electromagnetic field should do the trick). All of this is what I can remember from watching the TV show so maybe I'm off with something XD
What are the other crystals for? Well simple, red is for cherry taste, blue for blueberry, yellow for lemon. ... Ehm what? You did not know DHD's also produce gelato? :)
if i may the DHD does as far as we know does in-fact have a power source however it it not needed on certain planets and in certain situations also i believe that the control crystals for the Pegasus DHD are kept under the top of the pedestal not under the symbols however their are more than likely some under them anyway
what I never understood is this : 6 symbols are the target and the last one is the origin in an address, right? that means there each gate has its own unique symbol. that doesn't make any sense.
We know the gates require power though not alot as two army trucks produced enough electricity to do so as well as some fungi though the fungi was an organic source of cold fusion. So the question is what and where are the power supply. It's conceivable that the DHD has a power source that is exceptionally long lived, longer than a RTG or alpha decay battery (well maybe an alpha decay battery for a few thousand years but we are talking about millions of years), maybe thermal between surface temperature and underground temperature accumulated and stored over time when idle which brings to mind even a couple of thousand of years would be enough to bury these gates in sediment so whose been clearing the dirt, we've had entire Roman villas completely buried under tens of feet of dirt. But what of the STU gates where the DHD was a tablet and of the STA orbital gates... I suppose the gate itself could have a power source but certainly the Milky way gates were shown repeatedly to be unpowered.
Any one think it was odd that they could gather together hundreds? of Stargates for a galactic bridge but they couldn't find one extra DHD for SGC to use for at least an emergency backup?
It's probably best to stick with the pedestal DHD that came with the good old Chappa'ai. Trying to make you own (or messing around with something so complicated) invariably causes problems. Although it was good material for more than a few episodes.
Apparently the schematic of the DHD made for Fifth Race mentions something about 'cold fusion' as the main power source for the DHDs, or so I've heard.
@@TheStargateGuy I cannot make the writing out either. It was posted on a Facebook group, stating that that cold fusion was mentioned. I honestly wouldn't put it past the Ancients to have mastered cold fusion. It almost seems trivial to some of the stuff they've done.
@@ianclancy2261 I think it is messed up. In 2x03 Prissonners SG1 teams up with a woman who had a cold fusión type power source for powering the gate and dial out of the planet they were imprissoned.
Always wonder how they dialed. I get the last one is from the plant your are dialing on but how did the combinations work. I know on some eps they explained it but I cant get it. Where the six characters/numbers the same and only the last key is the plant they are on?
Is it just me or when the show first aired way back when didn't they say the DHD's were powered by ZPM's? I suppose it is possible I dreamt it, but I could've sworn I seen it on the show though
Nope sorry, if they were then whenever we needed one, we would just break a random DHD open and take the ZPM. No drama, no absolute need for the Atlantis expedition.
The Stargate Guy didn't McKay explain that when he wanted to take the one out that device from planet where they killed them selves a 25.., now that I think about it this could be what I'm remembering
on another point, certain people say that SGU was like BSG maybe even too much, but in 2001 Sg1 was going well and CBS started with Ent, but just as a thought the more current feel of that show could that have been partially inspired by SG1. would you agree that the same thing happened in 2009 as in 2001, more or less anyway
I wonder why they said in the original movie that Abydos was on the other side of the known universe but in the shows pilot, because of stellar drift, it became the closest gate to Earth. The gate is made fro naquadah, a natural occurring room temperature super conductor that absorbs any and all available energy from anything around it to work, with or without the DHD being present. this includes electricity (either from a power grid or lightning (Torment of Tantalus), cold fusion (Prisoners), Nuclear explosions (Chain Reaction), black holes (A Matter of Time, The Pegasus Project and Singularity), alien energy based life forms (Watergate) as well as other possible sources such as solar or static electricity. Is it just my imagination or does the Master Control Crystal look suspiciously like the Master Control Program from Tron? I know that there are 39 symbols on the Gate itself but I wonder if there are 39 on the DHD as well? The puddlejumper DHD also can't deactivate the Atlantis shield like the Atlantis one can
The original 1994 "Stargate" film isn't 100% canon to the series. They made slight changes but kept the same story intact. The Stargate doesn't even look the same from the film to the show. In the film, they even say that the gate sends them to another galaxy. The series retconed those aspects which i actually like alot more.
@@TheStargateGuy The fact that you can use so many forms of energy to power the gate AND the fact that so many of the gates are located miles, even thousands of miles from local populations in some cases shows that they don't need to be connected to a local power grid to work. DHD or gate itself
@@TheStargateGuy Was the DHD physically attached to the gate or did it work wirelessly? Because we've seen them move people move the gate to different places and I've never seen any cables running from one to the other. That would mean that the gate absorbs energy directly from various sources and the DHD just directs the wormhole to it's destination
He changed the coordinates of the Pegasus DHD to use the 7th symbol of that DHD as origin point from Earth. I think he dialed the Pegasus Alpha site but from Earth.
What are the connections between Jaffa Staff weapons and Jaffa staff cannons as power source ? Go auld Hatak use staff cannons as the main weapons ? Personally , i like the Aukesh for weapons as they look and sound different
that's a good question I remember hearing something like that happened in the multi versions of sg-1 teams alternates that passed through the blackhole and a council of carters thinking of a way to return them home
I think it's the DHD's that powers the gate through "wireless" connection (the Ancients were capable of creating devices taht would teleport anything between planets or gaalxies, so why not a way to power the gates without physical connection ?) but they need extra power from a ZPM to dial a 8 chevrons adress. And the only time a gate was powered by a planet's core was to dial the Destiny with the 9 chevrons, because that planet has a specific type of core but it restulted in the destruction of the planet.
The difference between the milky way and pegasus galaxy DHD make sense with different material behin available. But what about the gate itself. We know that the Gate in the milky way are built with naquadah but the structure itself of the pegasus gate are really different (more lean) would it be possible that the pegasus gate would be made out of entirely other material. In no point in SGA do they talk about naquadah (Beside of the Tau'ri Naquadah generator). Woudl it be possible that naquadah would be only available in the milky way.
I always thought the Stargate was powered by the magnetic field of whatever planet it is on. The DHD just needed small amounts of power for control purposes.
Nope sorry, If that was the case than the Earth gate would not need to be hooked up to the US power grid, and all of the times that SG1 didn't have a DHD they would not have needed to also search for a power source
@@TheStargateGuy well technically they only needed enough energy to free up the ring so they can dial manually after its dialled the gate can draw power from the destination dhd.
I think that yes, as if you go really far away back in time and change any event relative to the ascension of the Ancients, you modify the life of the ascended beings.
Yup, but it's coming back. We now have Stargate Origins and the MGM machine is starting to kick back into gear. Plus who cares if it's been dead for 10 years now. It has made a difference in people's lives and it still can.
See the only Two Issue I've ever had with Stargate is with the Gates and their various DHDs.

Thanks Phil I try.
I believe the smaller crystals outside of the MCC pit might be for running the lights under each key on the DHD as well as receivers for puddle jumper sent commands. They could also stand to be power spike diminishers in the event the gate is receiving energy surges from the dialing gate.

Yeah pretty much. That's why the Ancients put in "space gates" around the Pegasus galaxy.
you would think they would have some sort of "are you sure you want to connect to this gate" message pop up first.
Why you never see girls on channels like this?
I'm guessing the whole reason that the force shield is disabled when the puddle jumper activates a gate is prevent some idiot in the gate room from cutting a jumper in half by activating the shield.
Ba'al also seemed to have improvised some sort of handheld dialing device in Continuum (as did old Cassandra in the episode "1969").
Yup good point that is true. Both alternate timelines. :)
@@TheStargateGuy Perhaps Ba'al's time machine at the end of Continuum also qualifies as a DHD ?
I think portable DHDs were common among those who knew how they work. Even the SGC had a DHD laptop w/power source for situations where a native DHD was not functioning.
Don’t forget Thor and the Knox could open the gate without a DHD

The biggest hole I could find on my own with this theory, after some time thinking of it, is that this would mean stellar drift was enough since 1928 when the Alpha gate was moved away from its DHD to render all addresses but Abydos & Heliopolis unavailable, not thousand of years as the series states...
@@EllisWolf when you think about it though why does the dhd even need a poo symbol if it already knows its position in space
@@shaneebahera8566 a P.O.O. is the encoded position of the dialer gate. Since in 3d space, you need an (x), a (y), and a (z) in order to have a position, it'd make sense that the gate being dialed would send it's own P.O.O. back to confirm and establish the wormhole.
The Atlantis DHD dials quicker as well. Love the channel by the way. Pretty sure I’ve seen them all. I know I’ve watched some a few times
I always thought it odd that the DHDs in the milkway, looked very Goa'uld in design, but the gates themselves looked Ancient. The DHDs in the jumpers and in the Pegasus galaxy were more Ancient looking. Any ideas as to why the stylistic change in the Milkyway for the DHDs?
It's actually the other way around. Goa'uld designs were largely based on Ancient technology.
@@KohuGaly All I am pointing out is to me, the DHDs look more like Goa'uld design on the outside, than the gates themselves, which look more ancient in design. The Pegasus galaxy Dhds look more like an ancient version of a Foa'uld design. I am not talking about function nor who built them, just the outter casing's stylistic representations.
There's no in-universe explanation, unfortunately.
😅
Though I'd argue that the disparity isn't that great not least of all in the light of the disparity between Pegasus & Milky Way gate.
KohuGaly it’s just new technology our cell phones today look nothing like they did in 1995
Well the DHD's in Peagasus have the same black texture/design and I doubt that the Goa'uld had the power to reach that far out. And like someone else said, their tech is based heavily off the Ancients leading to similar dragons for some things
Nice summary, thank you. =)
But one thing I'm still wondering about is how the safety protocols work. Are they in the DHD or in the Stargate itself? Because in the "Red Sky" episode, the earth dialing computer apparently also had some restrictions that haven't been set up by humans. I don't remember if they have actually downloaded the whole data from a DHD at some point, but if not, that protocol has to be in the Stargate itself.
Also, there is a protocol preventing the wormhole going right through a sun, but not preventing accidental time travel involving solar flares, which I would assume could have been covered right there. Considering this happens twice in the show by sheer coincidence (SG1 "1969" and SGA "The Last Man"), it's hard to believe that the Ancients have never encountered this "glitch".
Solar Flares are random so would not be something they could calculate nor a sun going supernova and turning into a blackhole.
Great video, been watching a lot of your videos lately during my rewatch of SG-1. (I've seen seasons 1-8 of SG-1 and all of SG:Universe, but only a couple episodes of Atlantis. This rewatch i'm determined to finally get to the show everyone tells me is the best Stargate ever was.)
I wished Carter and McKay would have talked a little bit more about where they got the gates for the bridge.
Galaxy Depot?
I wish.
If i remember correctly McKay said they collected gates from planets that didn't need them. So i'm guessing uninhabitable planets.
@@tajayeb Correct.
It's interesting that science-fiction physics constantly try to say worm holes will be a method of transportation but they have no idea what a wormhole would be, what it would consist of the closest they say might be a tornado but again nobody has offered what a real tornado is made of
In the episode where they went back in time, they used an old army truck engine/battery to start the gate! That's not alot of power!
Yeah, that was some bullshit..
That's typical Hollywood total lack of understanding of electricity.
Good job my friend thank you for your infirmation.
most would be for the controls for the push buttons as they would require the info of all places each symbol could connect to as the amount of them is like impossible to just get right the first time and it would need to remember the other gates address to be able to connect at all
A great overview of the DHD, thanks.
A quick question: how is the Point of Origin symbol identified on off-world DHDs? Too simple to say they always occupy the same position. 🤔
It's probable that the Ancients programed where the planet was located, then took account of spacial drift like they did with other Stargates. Other than that, I don't really know lol.
I'm glad you liked the video. I believe that they didn't care about that too much. That they assigned a symbol to each gate, mapped out the network and set it to auto correct. :)
@@mustbewill They called the prop department and told them they needed a new simbol.
@@Mortlupo if it works it works lol
There is another control panel in the pedestal which houses other components like the buffer. The buffer stores information of what happens with the gate in the last usage until someone puts a new address into the system or it degrades.
Well it does keep a list of addresses dialed recently. However, when it comes to storing patters of things that have come through the gate that is in the gate itself. Take Teal'c for example.
@@TheStargateGuy That's what I was referring to but it also keeps the main programing for the stellar drift among other things.
Great description. Support it to 100%
Apparently the wraith darts also had some way of remotely controlling the Pegasus DHD's.
They must have Macgyve... oh nm.
@@skyserf Yep 😆
Yup, but they are Wraith, so we don't talk about them :)
@@TheStargateGuy You don't like to talk about the wraith ? I thought Todd the wraith was a great character. I loved his relationship with Shepard.
the episode where they went back and met General Hammond in the past, didn't they use a car battery to start the stargate? That's not alot of power.
They used a bunch of cars. like more than a dozen.
also, they werent really "cars", it was several heavy duty military trucks and jeeps, wouldnt be surprised if they found some generators in that warehouse as well
On power, I think a Stargate doesn't need a strong source of power, just enough stored power. I suspected that gates/DHDs absorb energy from the surroundings to enable dialing sequences to work. So, a single car battery running like a jumper would, after several minutes, charge a Stargate to successfully dial out. Portable dial devices (as seen in Continuum) would likely do the same...provide power if needed to dial the gate. A wormhole is limited to 38 minutes presumably because it's as long as this power charge sustains it. Whenever a limitless power source is attached, we've seen wormholes maintained indefinitely.
its explained in a few episodes they use manual dialing that the gate can draw power from the dhd or power source of either end of the wormhole so when they dial using trucks and jumper cables theonly needed enough energy to start the dialing process but not establish and maintain the wormhole
@@qdllc MOre like how long the wormhole stays stable enough for transit before the fail-safes shut it down unless overridden.
A Stargate by itself is fully capable of safe dialing. They have in built protocols to prevent such situations. They also have vast arrays of sensors and processing systems in built that it makes you wonder what the DHD itself is actually doing. The Destiny gates are a great example of being made using the most cheapest of materials but still having a good amount of sensors and processing not to mention storage for its raw data. On top of its secondary function of transporting people around.
So far my suspicion has been that the Milky Way gates+ actually have remote neural interfaces built into them. For the purpose of control by more advanced races.
My suggestion would be to consider DHD's an upgrade that was added after the Milky Way gates were built. They are far more programmable and updatable over the entire network. But most importantly, they allow lesser advanced races to use them no matter where they go.
As for their true function? My guess is it has to do with viruses and monitoring of travellers. Along with the ability to create matter in large amounts. Although it wouldn't surprise me to learn that the ascended Ancients were using them to gain their power from. Which is probably less of an issue since they wouldn't have a clue its happening.
The DHD definitely is an upgrade I agree, and the gates do have some built in safety features. But take a look at the episode Red Sky the Asgard stated that if the humans had a DHD it would have prevented them from getting a lock that would have destroyed the planet.
Another Great video Taylor thanks for the upload
Glad you like it thanks for watching!
No idea where I heard it, but I could have sworn the platforms that star gates sit on provide power to the gates.
Nope
the puddle jumper dhd has an all purpose point of origin input at the very bottom. if you think about it, it's obvious why it was designed that way
Indeed good point.
I suspect Taylor has a working DHD and Stargate at his home.
Why am I just now finding this! Do u have any videos on the Jaffa symbols on there fore heads. Different types for what gods. Also I do believe the DHD had a huge red crystal for a power source. Love the video. Gonna check out your others.
the reason they cant use the shield is explained in the episode where they return and take out the replicators they say they cant raise the shield due to them not having control of the gate in other words the puddle jumpers have a built in iff that auto controls the shield this would be so if they needed to access the gate room but could not they could use the gate and a puddle jumper to do it as even in the past the ancients could of used hyperdrive to get to another gate and then send the jumper through the gate to gain access
what about the guy who can dial a gate with his hand wrist remote thing? also in the 1969 episode, at the end, she dialed it with her hand remote too
I'm not sure if the Atlantis and puddle jumper DHDs are "better." The bulky DHD is clearly designed to withstand the elements. I wonder if the more compact units would fare so well if left outside. A DHD can be quite small if maintaining and repairing it isn't going to be a concern, otherwise you must over-engineer it to compensate for years of neglect and abuse.
if every gate needs a point of origin then surely the number of gates is limited to the number of symbols on the gate?
the gate should have used something like each symbol for a different pulsar and using that to triangulate a destination, so no need for point of origin
My theory is that there is one slot on the DHD that's for the point of origin symbol. However, as the movie indicated that symbols on the gate differ based on location in the galaxy, you'd think addresses would really be messed up to calculate...UNLESS they ret-conned the symbols to be the same on all gates (as seen from Earth) and the sequence of entry could still produce thousands of possible destinations.
I think there are the same 36 symbols on all DHD's and one symbol differs between all of them representing the point of origin. Still, it is a big amount of gates to exist. If I'm not wrong the amount of address availiable in the Milky Way (39 symbols - point of origin = 38) 38*37*36*35*34*33=1987690320 possible address. And that's just the 6 symbol sequence XD.
@@gpcexplorer makes you wonder how the point of origin symbol works considering the gate can still be dialed out even when its not in its original location. when Jackson dialed from the the mother he say he used earth as a point of origin but its highly unlikely that the dhd for that gate had an earth symbol to use as point of origin
Very cool, Taylor!!!
Now, we just need a video on "How Jack O'Nealls' mind works" Or is that something the Ancients would look at and say, "You're on your own guys! We're outta here!"
I'll go with the Ancient's answer there ;o)
His mind works!!! lol. That one is beyond my ability to explain, just like the Asgard.
maybe some information about the humanmade 'dhd' on earth?
That would take an engineering degree to figure out. lol. I'll add it to the list and try my best though.
It was built after months of research through trial and error and a couple of supercomputers trying to figure out the input and outputs that Earth's technology at the time could understand. Once it was found out how to "control" it in a crude way, some changes were made. New programming (fast dialing mode), skipping dialing steps for getting a lock and after the 8th season of SG1 a major upgrade to software was made although it seems that most interfacing technology was kept in the same way.
Power is supplied to the gate through a couple of inductors, possibly working like an RFID reader but with a much stronger power output to supply to the gate (as it can absorb any kind of energy, so in theory a strong electromagnetic field should do the trick).
All of this is what I can remember from watching the TV show so maybe I'm off with something XD
What are the other crystals for?
Well simple, red is for cherry taste, blue for blueberry, yellow for lemon. ... Ehm what? You did not know DHD's also produce gelato? :)
if i may the DHD does as far as we know does in-fact have a power source however it it not needed on certain planets and in certain situations also i believe that the control crystals for the Pegasus DHD are kept under the top of the pedestal not under the symbols however their are more than likely some under them anyway
Yup yup.
i was wondering if they could act like they were bluetooth connected. it connect to the nearest gate
what I never understood is this : 6 symbols are the target and the last one is the origin in an address, right? that means there each gate has its own unique symbol. that doesn't make any sense.
We know the gates require power though not alot as two army trucks produced enough electricity to do so as well as some fungi though the fungi was an organic source of cold fusion. So the question is what and where are the power supply. It's conceivable that the DHD has a power source that is exceptionally long lived, longer than a RTG or alpha decay battery (well maybe an alpha decay battery for a few thousand years but we are talking about millions of years), maybe thermal between surface temperature and underground temperature accumulated and stored over time when idle which brings to mind even a couple of thousand of years would be enough to bury these gates in sediment so whose been clearing the dirt, we've had entire Roman villas completely buried under tens of feet of dirt. But what of the STU gates where the DHD was a tablet and of the STA orbital gates... I suppose the gate itself could have a power source but certainly the Milky way gates were shown repeatedly to be unpowered.
Any one think it was odd that they could gather together hundreds? of Stargates for a galactic bridge but they couldn't find one extra DHD for SGC to use for at least an emergency backup?
They might of had one at Area 51 for more study. I don't know.
It's probably best to stick with the pedestal DHD that came with the good old Chappa'ai. Trying to make you own (or messing around with something so complicated) invariably causes problems. Although it was good material for more than a few episodes.
Indeed.
RE: Power sources. Didn’t the stargate inherently absorb power from the environment?
Apparently the schematic of the DHD made for Fifth Race mentions something about 'cold fusion' as the main power source for the DHDs, or so I've heard.
I couldn’t make hardly anything out of the writing so i don’t know about that.
@@TheStargateGuy I cannot make the writing out either. It was posted on a Facebook group, stating that that cold fusion was mentioned. I honestly wouldn't put it past the Ancients to have mastered cold fusion. It almost seems trivial to some of the stuff they've done.
@@ianclancy2261 I think it is messed up. In 2x03 Prissonners SG1 teams up with a woman who had a cold fusión type power source for powering the gate and dial out of the planet they were imprissoned.
DHD works through Bluetooth interface. Didn’t you know it?
great videos btw dude
I've always wondered. What did the ancients themselves call the DHD?
I’m not sure, something long and convoluted probably.
@@TheStargateGuy I did a Google search, apparently it was "clavis" I guess that means key in ancient.
stargate.fandom.com/wiki/Dial_Home_Device
Always wonder how they dialed. I get the last one is from the plant your are dialing on but how did the combinations work. I know on some eps they explained it but I cant get it. Where the six characters/numbers the same and only the last key is the plant they are on?
Is it just me or when the show first aired way back when didn't they say the DHD's were powered by ZPM's? I suppose it is possible I dreamt it, but I could've sworn I seen it on the show though
Nope sorry, if they were then whenever we needed one, we would just break a random DHD open and take the ZPM. No drama, no absolute need for the Atlantis expedition.
The Stargate Guy didn't McKay explain that when he wanted to take the one out that device from planet where they killed them selves a 25.., now that I think about it this could be what I'm remembering
on another point, certain people say that SGU was like BSG maybe even too much, but in 2001 Sg1 was going well and CBS started with Ent, but just as a thought the more current feel of that show could that have been partially inspired by SG1. would you agree that the same thing happened in 2009 as in 2001, more or less anyway
It's possible, I don't know of any quotes or evidence off of the top of my head that would support that though.
I know that, it's just an idea
I wonder why they said in the original movie that Abydos was on the other side of the known universe but in the shows pilot, because of stellar drift, it became the closest gate to Earth.
The gate is made fro naquadah, a natural occurring room temperature super conductor that absorbs any and all available energy from anything around it to work, with or without the DHD being present. this includes electricity (either from a power grid or lightning (Torment of Tantalus), cold fusion (Prisoners), Nuclear explosions (Chain Reaction), black holes (A Matter of Time, The Pegasus Project and Singularity), alien energy based life forms (Watergate) as well as other possible sources such as solar or static electricity.
Is it just my imagination or does the Master Control Crystal look suspiciously like the Master Control Program from Tron?
I know that there are 39 symbols on the Gate itself but I wonder if there are 39 on the DHD as well?
The puddlejumper DHD also can't deactivate the Atlantis shield like the Atlantis one can
The original 1994 "Stargate" film isn't 100% canon to the series. They made slight changes but kept the same story intact. The Stargate doesn't even look the same from the film to the show. In the film, they even say that the gate sends them to another galaxy. The series retconed those aspects which i actually like alot more.
Well in some of those instances the DHD was busted or not present, so power from other sources was needed.
@@TheStargateGuy The fact that you can use so many forms of energy to power the gate AND the fact that so many of the gates are located miles, even thousands of miles from local populations in some cases shows that they don't need to be connected to a local power grid to work. DHD or gate itself
@@TheStargateGuy Was the DHD physically attached to the gate or did it work wirelessly? Because we've seen them move people move the gate to different places and I've never seen any cables running from one to the other.
That would mean that the gate absorbs energy directly from various sources and the DHD just directs the wormhole to it's destination
How did Rodney alter the Pegasus DHD on the Super Hive in "Enemy at the Gate" to "Local Coordinates?
He changed the coordinates of the Pegasus DHD to use the 7th symbol of that DHD as origin point from Earth. I think he dialed the Pegasus Alpha site but from Earth.
What are the connections between Jaffa Staff weapons and Jaffa staff cannons as power source ? Go auld Hatak use staff cannons as the main weapons ? Personally , i like the Aukesh for weapons as they look and sound different
As far as we know they are simply liquid Naquadah that is charged so it's portable.
love the shirt!
Thanks.
arent the buttons just star signs
Mmmmm kinda yeah.
oh don't forget the zpm the zero point module for energy
Possible possible but then why wouldn’t SGC just canabilize them to get to and from Pegasus
that's a good question I remember hearing something like that happened in the multi versions of sg-1 teams alternates that passed through the blackhole and a council of carters thinking of a way to return them home
i thought that the gate gets its power from the planets core in sg1 anyway.
no idea about the orbiting pegasus ones tho.
I think it's the DHD's that powers the gate through "wireless" connection (the Ancients were capable of creating devices taht would teleport anything between planets or gaalxies, so why not a way to power the gates without physical connection ?) but they need extra power from a ZPM to dial a 8 chevrons adress. And the only time a gate was powered by a planet's core was to dial the Destiny with the 9 chevrons, because that planet has a specific type of core but it restulted in the destruction of the planet.
The difference between the milky way and pegasus galaxy DHD make sense with different material behin available. But what about the gate itself. We know that the Gate in the milky way are built with naquadah but the structure itself of the pegasus gate are really different (more lean) would it be possible that the pegasus gate would be made out of entirely other material. In no point in SGA do they talk about naquadah (Beside of the Tau'ri Naquadah generator). Woudl it be possible that naquadah would be only available in the milky way.
hunding1978 acording to stargate naquida was abundant in many galaxys
Well it could be that they just refined the material better and decreased moving parts which is possible as well.
I have a dhd dialing earth! Fox mccloud out help use the gate get home would now?
cool.
Dialing through BOOTES VOID?
I always thought the Stargate was powered by the magnetic field of whatever planet it is on. The DHD just needed small amounts of power for control purposes.
Nope sorry, If that was the case than the Earth gate would not need to be hooked up to the US power grid, and all of the times that SG1 didn't have a DHD they would not have needed to also search for a power source
@@TheStargateGuy well technically they only needed enough energy to free up the ring so they can dial manually after its dialled the gate can draw power from the destination dhd.
@@shaneebahera8566 It can? I always thought the sender needed to provide the power to maintain the wormhole
@@zethcader6478 yeah it draws power from either end , the sgc gate has no dhd so it pretty much relies on the other end to provide the power
I got a question that popped in my head. Does Time Travel affect ascended beings?
Off of the top of my head I'm not sure. I'll that question to the list of possible videos.
I think that yes, as if you go really far away back in time and change any event relative to the ascension of the Ancients, you modify the life of the ascended beings.
Reminds me of a certain dumpster.
Umm ok I’m confused.
@@TheStargateGuy I think you are too old to get the reference. Great channel nonetheless.
There can be two gates and dhd on one planet
Yes but only one gate can be hooked up to the DHD at a time.
Is the writing not in ancient on Jack's blueprints?
It's English it's just untidy and the resolution of the picture is not that great. At the time in the episode he could still write English.

The Stargate Network is powered under the hood by the Ethereum Galaxy Computer Blockchain Network invented by the Ancient named Buterin.

@@TheStargateGuy It's my own theory without any source. :D
WHERE ALL THE DHD MADE FROM NACWADTAD ???
Yup pretty much the same material as the gate.
Why do you say that the Destiny Stargate and DHD predates the Milky Way DHD.
It’s more primitive technology and the wiki page backs it up.
Stargate is Dead 10 years now.
Yup, but it's coming back. We now have Stargate Origins and the MGM machine is starting to kick back into gear. Plus who cares if it's been dead for 10 years now. It has made a difference in people's lives and it still can.
It has to me!
See the only Two Issue I've ever had with Stargate is with the Gates and their various DHDs. Namely with how the "Addressing works" and the actual precision required in plotting a course etc. For example the whole ideal behind the DHD and the references in SG1 etc. etc. is the gate system works like a telephone system. Meaning you "Dial" to go some where. If this was the case wouldn't the point of Origin be the first Symbol you dial not the last? or how about the 8th Chevron the so called Galaxy Area Code. What about the 9th Chevron the "Pass code" so to speak to get on Destiny? Even with current network packet transmission these codes are usually the first to be read so the packet can be not only sent to the correct destination but opened and read properly by that destination. Then we have the precision of the whole 6 points in space marked by star Constellations, that only works if you are within the visual bubble of those constellation once you exit them....yeah doesn't work anymore. More than likely why Atlantis and Destiny gates don't go with those style glyphs. Destiny makes it interesting by introducing an Ad-hoc method of scanning for gates much like wireless devices scan for access points. Ideally if this was the case a gate could then use the point of origin from other gates in the system to correctly depict its relative position etc. Which makes me think of another issue....if there are millions of gates in the system and only 39 or 36 glyphs on the gates themselves then gates wouldn't be able to be moved far from where they were originally located with out messing up major sections of the gate system.
