I have been on a Marco Reps Marathon for the last 4 hrs. I wish this guy was my neighbor. I could literally watch Him work all day long just to soak up some of His knowledge! Your, DYI JBC soldering station by the way, Rocks!
Hahaha, the 'inner hoarding tendencies' and 'higher purpose' comments are so spot on, I know that feeling exactly! If only I was half as competent as you, i might have found a higher purpose for half the stuff I have hoarded by now!
Having a real JBC i am very fortunate...this looks as good in operation and if I hadn't inherited mine from an office closure I would be building this!
I've the same hoarding problem, that's why i havent made videos yet, my projects always look like crap, i've also loved the sounds from dungen keepers, one of my fovourite games! This channel is pure porn!
@@reps That was a great game. If I could play it on my more modern machines I would - I still have the CD. (I could never get DK2 to play reliably, the random crashes ultimately stopped me for playing.)
I understand about 10% of what you're doing, but it reminds me of my father. He was a hardcore electronics geek from the 1960's. He would try to explain thing the same way, including your sense of humor. Thank you! Now I want one. Probably just buy the Pace ADS200.
Very nice! JBC tips are awesome, when drived properly it behaves as if it had unlimited thermal mass; and that turns soldering to joy. I'm using C245 tips with my DC powered DIY controller.
I may be wrong but if you're using the MOSFET as a switch you're using it in the "linear region" shown in the diagram at minute 3:10, which is the "ohmic region" otherwise it will not act as a low value resistor. You use it in the saturation region if you want a current source (current is almost independent of the drain to source voltage) or as an amplifier. The thing here is to charge the gate as fast as possible in order to lower the ON resistance (which is the slope of the curves).
No! You should most definitely use a Mosfet. The problem is using Mosfets as a Switch in the Saturation region. You want to use it in the triode (ohmic) region! When you look at the Characteristic Curve (Id x Vgs) you will see that when rising the Vds, the Id will maintain it's value in the saturation region. Why is that? It's Because the Mosfet is rising it's internal resistance. It will get hotter and have a higher drop voltage between Drain and Source. BJT's as Switches are used in the Saturation region. Mosfets as Switches are used in the Triode region. (very close to the Saturation Region for better performance)
i have watched this vid a few times.. really amazed by the level of skill and knowing what to do..you should start a kickstart soldering station ahahah....call it universal direct heating soldering station.. to avoid using the JBC name.. i would buy such a station in a heartbeat.. but i have the TS100 on order.. will see what that does.. for now i'm enjoying this content..
I'm a welder and my monkey brain doesn't understand this at all. But ill be damned if I don't love watching your videos Marco, thank you for putting in all this work for us.
Danke Marco, für das lehrreiche Video mit den ausführlichen Erklärungen. Ich würde das Projekt gerne für die T245 Cartridges verwenden, der Widerstand der Heizelemente ist dort aber anders als bei den C470. Dieser beträgt bei der C470 knapp 9 Ohm, bei der C245 nur 3 Ohm. Was müsste man an dem Projekt ändern, um auch die C245 Cartridges verwenden zu können? Ich wäre für jede Hilfe dankbar....
Woher hast du die Angaben? Dachte das die C470 eher einen kleineren Widerstand auf Grund der höheren Leistung hat als die C245 Reihe. Bin selber am überlegen welches Handstück ich mit kaufen soll.
Would you be willing to publish some more pictures of your PCB? And maybe you could tell me where you mounted the thermistor, as I'm currently trying to build a similar station for the T245 handle. Thanks a lot in advance ^^
The PCB is very special fitted to the enclosure and the parts (a wild mix of through hole and SMD) I had available, I don't think it will help. The thermistor should be at room temperature. Because I don't expect any excess heat, I have just put it directly on the PCB
ok you ve done a pretty good job there. well done. I'm thinking of making one following your instructions. Mind if you share an image of your pcb layout. Also what transformer did you use in your project? thanks a lot keep it up. subscribed
2017 ! And it is today that i found this. Great! The dangerous prototypes posts are a mess to read. No Release version view? No clear power limitation? what does 'universal' mean ?
Thanks for this. The ridens power supplies are programmable all be it sadly via a pc. Is there a reason that nobody is just interfacing them together with a temperature from tip, to control the output of the power supply?
Regarding to tip connection. In TS100 they are using custom copper connector, similar to your fuse type. Maybe you can create your own from copper sheet. in TS80 portable soldering iron is used audio jack. Find this tip type for affordable price can be difficult task. So far I found Weller WL26640 for 20e. Check for teardown of this soldering irons to see how it looks like.
Great, just what I was looking for! A simple DIY project vs. buying something from AliExpress. Do you by chance have the pcb file or any other updates for this project Thanks in advance.
For zero crossing detection - it's OK to just put a 1M resistor in series to protect the atmega from the higher voltage? Do the protection diodes of the atmega pins handle the rest? Or am I misreading the schematic
Why is nobody using rectfied 24v to drive the heater ? I think using a mosfet and controlling the iron with PWM would make for a very stable temperature.
I don't know for sure, a normal Type K thermocouple amplifier was reading more and more inaccurately at higher temperatures, so I don't think it is a type K. The constant in the voltage to temperature calculation that sparkybg (dangerousprototypes forum) has found seems to work well.
+Marco Reps Very nice update! I like the idea of the SSR because I'm working on some SSR right now. My questions is, do u think this SSR will work with AC current? I have ordered the photovoltiac IC's (VOM 1271) and still waiting for them. Any tips?
Definitely works with AC, that is what I am using here! If you want to make the circuit board yourself, I would recommend to use regular TO-220 MOSFETs instead of those tiny powerpak ones, because easier routing!
thanks for the video, a bit late but can you tell me what range of temperature can handle it, Thanks in advanced. Sorry if you mentioned it in the other video. but my english is not very well
First thank you for your video and work this is exactly what I've been looking for. Been trying to create wine with pwm but timing it for thermo measurement is a pain. Looking at your schematic for the zero crossing detect. I just see you tapped off the toroid with no resistor divider. Unless I'm looking at it wrong or missing something, would the IO pin get over loaded with the 24vac sine voltage? Any help would be appreciated
Hey look at a casual uC inpit there are diodes to protect it. So the diode is limitng the voltage and the resistor the current. To be isolated you could use a bridge rectifier and an optovoupler.
Can you reverse-engineer the jbc hibernation and sleep function for extending tip life? My guess is that the stand is isolated by its own grounding into the microcontroler. And that its shorting some input on the microcontroler trugh the single wire thats connected into the stand when you place the handpiece into the stand. Would be nice to see that function 😁
I'm building a project using a c245 cartridge that uses DC power because I have an old laptop power supply. It's 19.5 volts with 6.8 amps, well it just enough for the cartridge. But there are a few problems here, Marco uses AC power while I use DC power. I have a reference to Aixun T3A, it uses 1 P-channel mosfet AO4413, obviously will have to modify the design of the power supply part for the cartridge but I don't know if it is necessary to modify the temperature measurement part and code?
Great video think I will have a go at this project! :) Just a few questions...what printer and transparency sheets do you use?? Im struggling getting nice pcb's with the toner transfer method. Also do you not still use your proxxon?? Nice solder mask. A video on your current PCB making methods would be a good watch. Thanks.
Cheap Brother hl-2270dw, Folex Transparencies (4220.5.141). The prints are not perfectly nontransparent but with precise timing (1 min 15 s with my 4-tube tanning bed) the results are perfect.
I wonder why you discarded the integrated SSR device. I have nearly identical S202S02 and it works perfectly at 25VAC although it's also specced as 80Vmin...
Hello, Very nice work, i'm thinking of creating the same kind of soldering station using DC instead of AC maybe feeding the tip with a flyback boost input source so that the soldering station could be powered by a battery. I was wondering, if the tip is powered by a transformer and the rest of electronic by an another, they should be isolated from each other, so it should be possible to monitor the voltage on the thermocouple when powering the tips, what do you think about that theory ?
Because the thermocouple shares the one heater wire it will read totally wrong when the volt drop/resistance losses in the common wire swamp the millivolt thermocouple signal. You can use the same technique with your boost converter of disabling the power when you want to take a reading. You will need to possibly use an isolated transformer output to prevent the ground issue though.
Hi, thank you for the great job... a doubt, where is connected the pin CT (GND-green-JBC) that appears in the scheme?, on earth (PE)? I see that ACA1 and ACA2 (24V ac) are the connections of the first secondary transformer and ACB1 and ACB2 (24V ac) the second secondary, the transformer I think is a Sedlbaver Typ-NR RTO826053? Is it necessary to have a good earth in the house for it to work properly? Thank you
I have had tip red hot, get this for 6, 7 seconds. Foolishly increased max temeperature in software to 450, but measurement stops about 420. Is there discusion on software somewhere?
I really enjoyed this one watched it 3times hahhaha cool. There are a couple of cool kits being sold on Banggood called diy t12" or "STC-T12" perhaps next project ??? To see how it performs and such don't know if I could build such a cool soldering iron I'm an it nurd not a engineering god like you... still fun to watch and waiting on the next TS100 ... TS-xxx

Worth it then?
Ordered the items to build your project :) Cant wait to see the result and have a good soldering station. Thank you for the schematics. Good luck.
How much did it cost in time and money?
The grave yard effect was cool. I had to watch it 3 times. Now I'm going back for one more.
That case must be worth more than most stations. Sweet build.
I love the boneyard/grave scene. Nice stuff!
awesome project, I like the way it looks in the end with the black enclosure and the performance isn't bad at all.

YES! That's it! Please, don't use the MOSFET as Switch in the saturation region! That for BJT's.
Unfortunately Macro does not understand MOSFETs
The Cgs of the Mosfet is very small, it almost charge instantly, it passed the ohmic region very quickly, so remind me why won`t use Mosfet again ?
No! You should most definitely use a Mosfet. The problem is using Mosfets as a Switch in the Saturation region. You want to use it in the triode (ohmic) region!
When you look at the Characteristic Curve (Id x Vgs) you will see that when rising the Vds, the Id will maintain it's value in the saturation region. Why is that? It's Because the Mosfet is rising it's internal resistance. It will get hotter and have a higher drop voltage between Drain and Source.
BJT's as Switches are used in the Saturation region.
Mosfets as Switches are used in the Triode region. (very close to the Saturation Region for better performance)
there are MOSFETs that are specially designed for that kinds of scenarios, so generally speaking, not always the case
Oh the iron y . What a great solder station it is . And some extra edit time for the special fx. Great video
I learned so much from watching this build. I think I'm going to try and build this Thanks for all the insight and all your other videos
I don't understand any of he's saying as I'm not into electronics but why is it so satisfying and catchy to watch lol
Hi, great project. All is missing is a stand, in witch tip goes to sleep mode, cools down and saves its life when in breaks between soldering.
finally the day I've been waiting for. thank you so much for all of your efforts and videos ... thanks for sharing
have used those MOFTES Series in a DCDC Converter, they are so nice.
I know the hoarding problem, i feel with you!
Naja hab meine ja auch bald fertig. Durfte bloß nochmal neu anfangen weil ich mir meine Komplette Konstruktion zerschossen hab ;-).
not true, but under the best "electronics video ever made" to be precise.

Nice dota music by the way
That Infernal Machine sound effect brings back some good memories!
Nice! Totally understand the hoarding thing! "Oh I can save that for a better project! But this is a better project!"
Looking back at these amazing old videos, it is a bit sad how much sponsorships, as great as they are, take away from DIY channels.
This feeling I'm experiencing, is it iron envy?
wow. that thing looks awesome! i think i would have been compelled to use an oled display to top off the sleek look.
How much did it cost (except the housing)?
The tip + handle costs about 100€ and the controller costs about 15€ probably (my approximation).
The transformer will set you back a lot. Most of the cost of the controller is in that.
His audio grade toroidal transformer is expensive. A switching power supply may be a budget choice.
would you please upload a pdf file of the pcb ?

Ok, thanks ^^ After a bit of calculations, it would seem like the thermocouple use is a type N, but I'm not quit sure...
