Part II: Powerful DIY JBC Soldering station finished

Cheap clone compatible with JBC tips www.banggood.c...
More from me: / marcoreps
This was long overdue! I am tying up some loose ends from the popular JBC soldering station video. The new design is simpler, cheaper, more efficient and equally powerful. I have learnt a lot about solid state relays in this project and I hope you will too.
Schematics and software:
drive.google.c...
If you are not sure whether you should build this, take a look at dangerousprotot... That is a well tested, often built and much more universal soldering iron controller than mine.

[@mikeselectricstuff]

When you do homebrew PCBs, it helps to put a small (0.5mm) hole in the through-hole pads - makes it much easier to hand-drill as the holes act as centering marks and help to guide the drill to the centre

[@dl8cy]

awesome! really great work! your senses of humour and calm comments makes your videos 100% perfect

[@reps]

Means a lot, thank you!

[@cellularmitosis2]

Really love the style of these videos!

[@salifrtsalifrt3817]

Very imformative And funny i guess Good job

[@ilozeet]

bitte! ;)

[@ronniepirtlejr2606]

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!

[@apaskiewicz]

I just bought the house next to him for this exact reason!

[@raphaeljamar2451]

Discover you with Greatscott JBC solder station. Yours are better and I like your approach and your humor.

[@Leonelf0]

2:38 Technically, both MOSFETs are turned on. The back to back configuration is necessary to also block in the reverse direction, but reverse biased MOSFETs can also "actively" conduct backwards, since they are unipolar devices. This is the same as running a very low resistance resistor in parallel to a diode: Almost no diode losses

[@Rich77UK]

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!

[@richardwilliamjohnson8566]

Worth it then?

[@TheMadMagician87]

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!

[@KeesHessels]

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.

[@hollygame7103]

How much did it cost in time and money?

[@ziopoe]

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]

Yeh, the good old Dungeon Keeper 1 days :)

[@sklepa]

Put it on door/window D shape gasket on bottom, and a lot of hot glue on the top :D and its almost completly silent :D

[@Shaun.Stephens]

@@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.)

[@procactus9109]

The grave yard effect was cool. I had to watch it 3 times. Now I'm going back for one more.

[@MrBrymstond]

That case must be worth more than most stations. Sweet build.

[@telegraph_hill]

I love the boneyard/grave scene. Nice stuff!

[@attackaffection5444]

Your channel is a hidden gem I found today

[@Thermosphere]

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.

[@GuilhermeRochaFast]

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

[@voltlog]

awesome project, I like the way it looks in the end with the black enclosure and the performance isn't bad at all.

[@estern001]

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.

[@TecKonstantin]

have used those MOFTES Series in a DCDC Converter, they are so nice. I know the hoarding problem, i feel with you!

[@ltech4174]

Naja hab meine ja auch bald fertig. Durfte bloß nochmal neu anfangen weil ich mir meine Komplette Konstruktion zerschossen hab ;-).

[@TecKonstantin]

not true, but under the best "electronics video ever made" to be precise.

[@dariusleckas]

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.

[@geurra6559]

That Infernal Machine sound effect brings back some good memories!

[@splashman63]

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

[@CesareAli]

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).

[@MatheusErvilha]

YES! That's it! Please, don't use the MOSFET as Switch in the saturation region! That for BJT's.

[@aqib2000]

Unfortunately Macro does not understand MOSFETs

[@obtsai8015]

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 ?

[@MatheusErvilha]

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)

[@FooBar89]

there are MOSFETs that are specially designed for that kinds of scenarios, so generally speaking, not always the case

[@chriswouse7713]

Nice! Totally understand the hoarding thing! "Oh I can save that for a better project! But this is a better project!"

[@DoRC]

wow. that thing looks awesome! i think i would have been compelled to use an oled display to top off the sleek look.

[@samdeur]

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..

[@ParthBhat]

finally the day I've been waiting for. thank you so much for all of your efforts and videos ... thanks for sharing

[@change_your_oil_regularly4287]

Why am I still so interested in this when I have a JBC soldering station? 🤔 Great work thanks for sharing 👍

[@Split10uk]

Great video. Thanks for taking the time to share this. Love your sense of humour as well!

[@DoctorNoMD]

This feeling I'm experiencing, is it iron envy?

[@Baptisteiom]

love the dungeon keeper 2 sound effect at the start, made me want to fire up the game again....

[@xenonmaster]

I loved the DungeonKeeper 1 hatchery intro!

[@ddavity]

I love your channel man, it's amazing and adds a bit of funny too! Nice dota music by the way

[@EdwinSteiner]

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.

[@PiperFishing]

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.

[@NetAndino]

Thank you very much for sharing the information

[@16mmDJ]

Loving the editing recently!

[@alexandru-danielpopovici7293]

You have way too few subscribers for the quality and entertainment that you pleasure us with.

[@MatejBosansky]

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.

[@johannratschiller8586]

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....

[@tcurdt]

Johann, hast Du in die Richtung noch was herausgefunden oder probiert?

[@maxw.7118]

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.

[@radry100]

How much did it cost (except the housing)?

[@tunahankaratay1523]

The tip + handle costs about 100€ and the controller costs about 15€ probably (my approximation).

[@vejymonsta3006]

The transformer will set you back a lot. Most of the cost of the controller is in that.

[@phuang3]

His audio grade toroidal transformer is expensive. A switching power supply may be a budget choice.

[@DougHanchard]

Wait.. what.. you built your own sodering station? Impressive.

[@tarunarya1780]

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?

[@RedToxy-rc7ev]

Would it be adequate and aesthetic way to control power by using solid state relay on high voltage side of transformer if it have minimal V?

[@symik3]

OH, geez, very well done!

[@Whatsthegeek]

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.

[@byoung255]

I love the juxtaposition of After Effects and Paint.

[@codydiehl6443]

That came out amazing

[@oha5929]

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?

[@dimitris470]

Very nice Marco. Thanks for sharing

[@frantisekskudrna9232]

would you please upload a pdf file of the pcb ?

[@MrTigger015]

[@brantwinter]

Never mind my previous comment ! I found this video ! Will there be a PCB layout / gerber files released ? I would love to build one of these.

[@WestEast3259585]

mad editing skills

[@TheFoxz2]

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

[@m.emrahozkaya9903]

this one was just great, maybe you could even fix the overshoot with smaller time increments in monitoring?

[@emtakarohidemty4405]

you should ground the case of the station and the tip too

[@CCTVReport]

What if simply use pid controller with jbc handle ?

[@ytbTheogr]

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

[@ZiyaanMuhammed]

The intro caught me off guard 😂😂😂

[@1959Berre]

Nice job, well done. Great design too.

[@PeterMilanovski]

Hoarding Tendencies!!!! That needs to be a reel shit... Love it.

[@FbnGmr]

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 ^^

[@reps]

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

[@FbnGmr]

Alright, thanks for answering so quickly, but doesn't the current through the body diode of the mosfet create considerable amounts of heat?

[@goranstecesin1186]

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?

[@daitedve1984]

Marc, are you happy with your DIY station or you use another station? Is there reason to make this station now? I read A LOT about modern "china clones of JBC", but all of 'em are clumsy w closed firmware and even break after one month of use. I want to make own JBC-clone station, but with more advanced control. And people say you use AC current, instead of DC - any reason for that?

[@leonardodominguez4470]

Hi. Could you tell me what CAD software you use? I do not know him and I can not open the schematic. Thank you

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...

[@user-ug9nn]

Nice project, but the only reason to do a project like this is for tip calibration from microcontroller software. Of course a project like this already done only require a microcontroller software update for this feature.

[@HolgerBarske]

Very convincing. Thank you very much. And I would use one of my Lemo connectors 😬.

[@a.hashik4786]

[@SuperLeoSG]

Excellent result!

[@radioelf]

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

[@robertbishop9229]

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.

[@jandusek5501]

Did you make it?!

[@omitsura]

Nice! Must have front-panel power button though

Why not to ground red instead of blue? Then there would be a possibility to drive heater with p-mos. Of course in this case PE cant be the same potential as PSU's dc ground

[@1pcfred]

It sure seems to me like folks don't like to drill holes in circuit boards. Personally I find it a rather relaxing activity.

[@felixokeefe]

Maybe a stupid question but I'm going to ask anyway. Why not drive the heater element with DC instead of AC? Surely that would make things far simpler.

[@Anvilshock]

7:00 - Okay, that cannot possibly be a real attic. Surely you built that set just for that shot out of empty yogurt cups and masking tape using an angle grinder! No real attic would be THIS empty, clean, and uncluttered! Also: 10:30 - OH GOD NO PLEASE NOT THE WATER TORTURE AGAIN

[@grozaadrian4134]

the project camed to and end and is very nice ! you could of bought an hirose rpc 1 connector for it .. since thats what jbc usess :)
