There have been a lot of negative comments about this being an E14 advertisement! Obviously these people have never tried to design a product for production. A company like E14, Digikey etc need to be involved at the design stage to check that all components are affordable AND have multiple sources. Single sourcing has sent many good designs to the scrap heap when that source dries up! Great to see your design process in action. Keep up the good work.
I hope for an episode where ben builds somthing that sounds impossible/like not a good idea and manages to make it possible in the end, just like the old videos. if i wanted to watch industrial design, I would watch videos on that topic.
Good episode. I liked the part with the guy from E14 but wish they'd have summarized it at the end with some overlays or something to show the viewer the key points in the context of the larger project.
@TBHS Suggestion for an episode. I was thinking can a driver board be designed to run kindle epaper screen? Raspberry pi projects would be great to use.
the transformer would be much much heavier. The grid frequency is 60 Hz. For 60 Hz you need comparatively heavy iron core with quite some cooper windings. Rectifying it (making it DC) is easy. The next step is to high frequency switch it and then to use a small transformer. The higher the frequency, the smaller the transformer. I mean: Look for an old power supply around to use. You know when it is old, when it is for something simple but is way heavier then a modern one. Safety is kind of a silly argument at this point: The circuit is encased and for safety - when the case is closed - mainly the insulation between primary and secondary side matters. How much of the circuit is on which side does not matter too much.
Hi, at 4:15 your rectifier is turning AC into PULSED DC 120Vdc is actually 120 * 1.414 = 169Vpeak .Then you use a transformer to reduce the voltage?????? "Change of Plan", good idea, that module does it better, AC to DC with filter cap, SMPS IC to chop DC through high freq transformer, then to rectifier and filter caps and 5Vdc output with a little bit of feedback to regulate the output. Well done Ben..
Is it more efficient to convert AC to DC and then drop the voltage or drop the AC voltage and then convert from AC to DC? Which loses the least amount of power or produces the least amount of heat?
Discounting the possible cheapy Chinese switching power supply here im not sure I would be wanting to run mains power through that prototype PCB. I'm wondering how much flash over could be an issue with this prototype PCB in an over voltage situation? Not to mention if it would burn or set alight under these circumstances. Could be ok for just the prototype im guessing though? Great project otherwise.
ABS is the better option since it typically has a higher melting point. The design of a glue gun typically has thermal isolation, such as a ceramic ring.
i almost think it would be better to convert a soldering station to a glue gun station. can hack those? add to code or something. has the heater on a cable, more heat capacity and faster heat up (and cool down, maybe) and just need to add a trigger and motor and a nozzle. i would think that they wouldn't be too far apart as in controlling a heater cartridge if just using the one on a glue gun.
The trigger should be tactile! Otherwise it would provide no feedback for the user. Why not just go with a mechanical switch with a little spring that resets the trigger?
one way or another, need a plug and cable. make the gun lighter, power box w/ controls and pigtail ac cable long enough. i mean it will minimize the cost, cause i don't mind a square enclosure. adjustable temp knob and feed rate. can use standard glue gun with case mod or new case to hold motor, heater and trigger. 2 cables with mutiple wires would allow more options for size, maybe intergrate it with a popular mcu like an uno or some thing with built in wifi like a zero w pi?, the zzero with wifi or a pi-3
Could you simply place a magnet directly over the hall effect sensor held in position with a spring, Then use a thin wedge or ramp attached to the trigger, as the trigger is pulled the wedge gradually increases the distance between the magnet and sensor . Replacing the neodymium magnet with a simple ferrous magnet may give a better range and sensitivity to the trigger.
There is a awesome thing with Silabs MCU's, when you programm them in C you can use sbit to simply add a name to a port pin and set it's value. Example: sbit LED1 = P0 ^ 1; // This would be Port 0 and the second pin "pin 1" LED1 = 1; //then you can simply set the value of the pin :) This is very usefull for simple applications :)
@Brad yeah.... Ben would be wrong in either case. Either it is pulsating DC with 110V RMS or after smoothing "real" DC with 170V. But hey: Ben is a designer, a visionary, not an engineer. I mean: I like the show as a show, but some people think that Ben is some kind of electronic wizzard, when in reality, he relays on his team and element14. (yet, having the element14 rep in the show rubbed me the wrong way - any representative of a company has to explain me first how he makes profit, before I listen to his offered services.). Ben is great at what he is doing, but the show does not show the "off camera work" (how could it show that?), where the roles of him and his team are different.
Jay Walt in all technicality that is 110 VDC that meter measures the average of the 170 volt spikes to get that. And as a side note there is no such thing as a true RMS DC measurement on a multimeter. RMS voltage is only used in AC mode.
Eman2000 I agree to some degree. the 170 peak is not noise though. If you filter it it would still be 170v and you certainly wouldnt use a cap rated at anything under 170.
PirateKitty well I was kinda making fun at the fact that most Americans don't bother trying to fix things themselves and rather either pay someone ridiculous amounts of money to do it or buy a new one. Yes of course if it cost more to fix than just replace that's the better option but with a lot of things most of the cost is labor and obviously if you do it your self then you have just eliminated most of the cost. I find this especially true with cars when it starts to get to the point where the car is just not worth more than scrap metal. Yea replacing or re building an engine is not easy for the average home gamer but replacing brakes or other potentially labor intensive stuff isn't so much hard as time consuming.
You do have an excessive spending mentality PirateKitty. You might not be able to see it from (quite literally) the rest of the worlds perspective, but statistics prove that without a doubt. So for anyone reading this just enjoy Moo Techs joke and stop worrying about it.
Commonly heating elements are around 1500 Watts. So, if you use a 5 VDC the current required to timely melt glue is 300 Amps. There isn't enough room to have wires that can handle that much current in your hand.
can you not use 2X BD131 NPN transistors and 2X BD132 PNP transistors for your H-Bridge might give you some leeway and more torque from the motor to better feed the glue stick, an XBOX360 power-brick could supply the power for the glue gun moving the High Voltage of the glue gun as the XBOX360 power-brick supplies 12v, 5v,-5v and possibly 3v.
I don't complain often but this video was awful. Nothing got done, there were no solutions presented for the problems (Hall effect), and the whole video was a scripted awkward ad conversation.
No wonder Ben let him introduce himself with a name like that. The way Hari says his own last name sounds like it even annoys him trying to pronounce it. damn i thought telemarketers had a hard time pronouncing my real last name.
I know that e14 sponsors this site, and there is the long interstitial advertisement in the middle of every video which is fine--Ben and the crew need to earn their living. But here, the content itself was perverted into a commercial for e14, which was very disappointing.
most start by saying I love the show. but this glue gun has gone on to long. come on let's have something else. more of the retro game console mods. Even if it's just for me!!

Great to see your design process in action. Keep up the good work.
Anyone else concerned about him resting his fingers on the protoboard whilst 110v AC is flowing at the other end of it?...
I hope for an episode where ben builds somthing that sounds impossible/like not a good idea and manages to make it possible in the end, just like the old videos. if i wanted to watch industrial design, I would watch videos on that topic.
thumbs up for the instant fail, blue smoke monster release. That's why I always buy 5 or more of everything!
FULL BRIDGE RECTIFIER
wait wrong channel
If this was that channel, the glue gun would spark and blow GFIs...lol
joenne I always prefer bridge rectumfryers
rectifier? i hardly met her! ill leave now...
Electro boom has full bridge rectifier and ave has the rectum-frier
I wanted to write the same..... FUUUUUULL
Hey guys... What´s about the n64 portable?
They're hoping everybody will forget about it.
I love this channel so much. It's like if Ray Stantz had his own electronics show, so good.
Ooooh, finally you guys are doing the "coming next week" a segment at the end of the video!
Good episode. I liked the part with the guy from E14 but wish they'd have summarized it at the end with some overlays or something to show the viewer the key points in the context of the larger project.
@TBHS Suggestion for an episode. I was thinking can a driver board be designed to run kindle epaper screen? Raspberry pi projects would be great to use.
Uhh why was the rectified voltage lower than the line voltage?
Nevermind it wasn't being smoothed.
Why not step the voltage down first before converting to DC? (seems a little safer that way).
the transformer would be much much heavier. The grid frequency is 60 Hz. For 60 Hz you need comparatively heavy iron core with quite some cooper windings. Rectifying it (making it DC) is easy. The next step is to high frequency switch it and then to use a small transformer. The higher the frequency, the smaller the transformer.

Thanks for the explanation, makes sense.

Well done Ben..
About the bridge rectifier: Is it a FULL BRIDGE RECTIFIER?
I'm finding it really interesting seeing the whole development cycle for a product like this. Keep it up! :)
Is it more efficient to convert AC to DC and then drop the voltage or drop the AC voltage
and then convert from AC to DC?
Which loses the least amount of power or produces the least amount of heat?
I love this project (mostly because I really want to buy one at the end). Can't wait for next week's video. Good luck TBHS!
Discounting the possible cheapy Chinese switching power supply here im not sure I would be wanting to run mains power through that prototype PCB. I'm wondering how much flash over could be an issue with this prototype PCB in an over voltage situation? Not to mention if it would burn or set alight under these circumstances. Could be ok for just the prototype im guessing though? Great project otherwise.
A great and long ad for e14. Annoying that there had to be breaks for some of the actual show.
are 3d printed parts a good idea? I'm able to melt PLA with the tip of my glue gun
ABS is the better option since it typically has a higher melting point. The design of a glue gun typically has thermal isolation, such as a ceramic ring.
Nice to see I'm not the only one who over engineers simple things. Magic smoke another thing we have in common.
I would love to get such a Glue Gun. But im from Germany, so... 230VDC. Plus, im a bit worried about the reliability, with all that Tech involved.
I miss the old thumbnails :(
What's wrong with the new thumbnails?
Idk they just seem like a step back. The other ones caught my eye.
Oh I like Felix and Karen :)
Love the progress guys/gales.. Can't wait to see the final prototype.
Finally, a video, third of which is e14 ad.
Ben: Would you like to introduce yourself?
Hari: Sure my name is Hari Kalyaohgoawdamnlongname
Ben: *in mind* So that's how you say it
i almost think it would be better to convert a soldering station to a glue gun station.
can hack those? add to code or something. has the heater on a cable, more heat capacity and faster heat up (and cool down, maybe) and just need to add a trigger and motor and a nozzle. i would think that they wouldn't be too far apart as in controlling a heater cartridge if just using the one on a glue gun.
The trigger should be tactile! Otherwise it would provide no feedback for the user. Why not just go with a mechanical switch with a little spring that resets the trigger?
Maybe use two Hall effect sensors?
one way or another, need a plug and cable. make the gun lighter, power box w/ controls and pigtail ac cable long enough.
i mean it will minimize the cost, cause i don't mind a square enclosure. adjustable temp knob and feed rate.

Replacing the neodymium magnet with a simple ferrous magnet may give a better range and sensitivity to the trigger.
why don't you import the picture directly into fusion 360?
There is a awesome thing with Silabs MCU's, when you programm them in C you can use sbit to simply add a name to a port pin and set it's value.
Example:
sbit LED1 = P0 ^ 1; // This would be Port 0 and the second pin "pin 1"

This is very usefull for simple applications :)
Super Glue Gun! Otherwise known as "Overly Engineered Gun That Should Have Used A Pot Instead Of HEF's and Lots Of Code!"
I really need a gluegun like this.
When will the Super Zlue Gun available for sale ? and if yes, how much will it cost to buy one of them ?
Will you make in 220V version >?
LOL !
Guns, BOMs, and exploding circuits?
All the interview was missing was Ben holding a note card saying: This man blows goats...... I have proof
The bridge rectifier should output around 170v pulsating DC, not 110vdc... Come on now, geez...
The meter is might be doing a RMS calculation
@Brad yeah.... Ben would be wrong in either case. Either it is pulsating DC with 110V RMS or after smoothing "real" DC with 170V. But hey: Ben is a designer, a visionary, not an engineer.

Jay Walt i agree with that statement but only if you put a cap across the output. And of course he doesn't have one.
I think it would be great if you ( The Ben Heck Show ) had an episode with an introduction to Linux on UA-cam (not just on the the Element14 website).
There... may be... something in the works.. something something wednesdays
I thought the American way was to just throw it out and buy a new one
Not an American phenomena. May be you should get it fixed for $40 when you can buy a new one for $10.
That would be smart. No?
PirateKitty well I was kinda making fun at the fact that most Americans don't bother trying to fix things themselves and rather either pay someone ridiculous amounts of money to do it or buy a new one.

Why put the AC in the handle, why just make your glue gun use a power brick to offload that space and complexity to an off the shelf part.
You need 120V AC for the heating element of the hot glue gun.
Commonly heating elements are around 1500 Watts. So, if you use a 5 VDC the current required to timely melt glue is 300 Amps. There isn't enough room to have wires that can handle that much current in your hand.
Makes sense, I wasn't thinking about the melting glue aspect, just the motors. That's why they don't let me build hot glue guns!
Anywhere near that. The heating element of a hot glue gun it's around 30w. Not even close to 1500w
everytime ben says "AC" or "DC" my siri triggers. and he does say it a lot in this video xDDD
can you not use 2X BD131 NPN transistors and 2X BD132 PNP transistors for your H-Bridge might give you some leeway and more torque from the motor to better feed the glue stick, an XBOX360 power-brick could supply the power for the glue gun moving the High Voltage of the glue gun as the XBOX360 power-brick supplies 12v, 5v,-5v and possibly 3v.
Someone needs to put an absolutely count on the guy from element 14 😂
Ow and a "argh" count 😂
A programmable hot glue gun
Now I've seen it all
can you do a game boy game with a modern data saving system please?
schematics?
i would of made a power brick with all that stuff in to it the only thing that goes to the gun is the motor wires and trigger wires
I would really like to see n64 portable I know it's hard but it would make a great episode
Or finish it
If they make this hot glue gun with a 240v compatible circuit then i'll buy one!
I don't complain often but this video was awful. Nothing got done, there were no solutions presented for the problems (Hall effect), and the whole video was a scripted awkward ad conversation.
The info-mertial at the end was pretty bad but I do understand that E14 is what pays Ben's check
And the audio varies in volume quite the lot.
Yaaay Hari is here to handle business!!!
No wonder Ben let him introduce himself with a name like that.
The way Hari says his own last name sounds like it even annoys him trying to pronounce it.
damn i thought telemarketers had a hard time pronouncing my real last name.
Pretty sure Hari is a cop
ben your looking like logan
can you show us how to build a nintendo switch
I know that e14 sponsors this site, and there is the long interstitial advertisement in the middle of every video which is fine--Ben and the crew need to earn their living. But here, the content itself was perverted into a commercial for e14, which was very disappointing.
좋아요 !
hey ben make some of my ideas please
the only thing that I understand is the programming..everything else just blah...blah..blah but it's fun to see this video
I glu gun
Again?
Boooriiiing.
most start by saying I love the show. but this glue gun has gone on to long. come on let's have something else. more of the retro game console mods. Even if it's just for me!!
Third!
schematics?
