The simplest soldering station on T12 tips 

Fantastic project, great channel, unique on YT to have such a great approach to reuse, I recommend the channel regularly to people.

Great project and very nice result. Goes to show that you can achieve high quality soldering without spending a lot of money.

Love the soldering station videos. Next: JBC T245

You have become my favorite RU-vid Channel. I wish I were your personal student. Great work.

Hello from Poland. I love watching your channel. Great idea as usual. Thanks for another fantastic project. I'm waiting for the next great episode. Thanks, mate.

On the schematic there are only two 100nF capacitors, but on the PBC there were three. Also, on the schematic the electrolytic capacitor was connected to the output of the IC7805 but on the PCB it is on the input.

Dear friends,This is only for 24v dc soldering iron whicj comes with kada etc soldering station. Very nice job

Nice job. If you use acetone on a rag you can remove most silk screen text. I do *NOT* use an abrasive like a scotch brite pad most of the time as it will affect the surface finish. Most screen printing inks appear to be formulated from plastics similar to laser printer toner. Acetone acts as a solvent that can remove them. I use old tee shirts cut into shop rags for jobs like this. If a few layers of rags are used to cover the end of a wooden popsicle stick with a rubber band to hold the rag(s), it is possible to make a tool to work on smaller areas. I don't recommend using tape, or trying to mask off areas you want to keep versus remove. Acetone will find its way under almost any tape and will cause problems. If you really want to make a nice looking indicator scale, it is possible to use photoresist on a soda can and etch it like circuit board. It is easier to remove the outer painted surface of the can's aluminum. Don't damage the inner plastic coating. I cover this inside surface in an extra layer of box packing tape while working on the sheet of aluminum. Make the transparency mask lines around 75-80% the size of the final text. The aluminum will etch differently than copper. It tends to etch laterally (sideways) quickly while you are still waiting on the sharp edges to dissolve. I leave the aforementioned packing tape on the back surface of the aluminum when I etch. It is easier to control the process when only one side is exposed. After the etch is done the tape will help remove the coating that was on the inside of the can in the areas that have been etched through. You will still need to use a sharp razor to remove the rest of the liner coating inside the lettering, but this is easy. This process will yield a nice stencil. Now place the stencil on the surface, mask off everything else around it, and use a spray paint can to apply very light coats of paint to the stencil with the can held at 90 degrees and further away than usual. Do not be lazy and try to do 1 or 2 coats of heavy paint, or move the can side to side. Let very light coats of paint cover the work over time and do 8 to 10 of them with 5-10 minutes between each. I also use this aluminum can technique to make solder paste stencils. They work great too. -Jake

Muy creativo! Felicitaciones!

It is better to limit the VGS of the mosfet between 10..15V (add a resistor to the emitter of the bipolar so the drop across the GS resistor becomes the desired 10..15V). Operating it at the 18..20V, it will fail soon.

Many.many thanks this is I'm looking for last few days

I have some sugestion for your project :For exemple you cood use lm 317 with some resistor to get 5 v. The lm 317 have a beter termo stability and a curent consumation of 400a . And you will makeit more cood add the ground pin for the iron tip . În rest is a cool project

It would be nice if you willmake a digital display soldering iron for t12 tips and with all the features of the commercial soldering iron controller.

Very informative as always. Thank you

I would be very thankful if someone would explain in-depth how the circuit works

I assembled the components using the diagram shown here, when I tried it LED1 immediately turned on, and VR1 seemed to only provide a voltage range between 3vdc (minimum) and 3.7vdc (maximum). When I try to use a power supply to run the circuit and attach the soldering tip, the voltage will drop from 12vdc to 5.6vdc with a maximum current of 1.6. is there something wrong with my circuit. Thank you very much.

Please make hot air soldering station.

Thank you so much for sharing your knowlage and hard work, I would love to make one, but is it possible to add a displlay showing the temperature that is set

thanks for the diagram...im build it..very2 powerfull 👍👍👍👍👍👍👍👍

thank you

Not working. Where is voltage control points?

Nice ! Make a Video in which Temperature mesurement also show !

Love your videos, thank you. Subscribed.

I'm trying to change the mosfet with irf9540n, it didn't work. The mosfet was very hot, then my t12 solder tips were red hot burning. I use soldering tip ksger. Is there a solution to solve it? Thank you

Great project. What difference it does when connecting ground cable and not using it?? What will be the modification, if i connect ground cable? Thanks

Very nice

may you share the PCB layout

please provide pcb layout link

Does the two diode mandatory?

I have the simple controller for t12. Now I wonder what kind modification is need in the circuit to use AC24 volt for the heater instead DC. Any suggestion?

hi there I did it but I don't know why but the tip heats up very very hot .. first the led lights up whatever i connect the tip or not second i tried to see the voltage at the tip wire it gives me the same input voltage can u help me i need it to work very bad >

plz make with n channel mosfet

it can be use for C210 too ?

Circuit diagram upload??????

A few years ago I made a t12 station using arduino, a switch with bjt and P channel, and an op amp with 200 gain, one day the 7805 died and killed the atmega 328p, as I needed to solder I replaced the arduino with a comparator using the second 358 amplifier and it has been like this for 5 years, the only problem is an audible noise at 2KHz, but it is not the same design as the video, so I ask someone else has some noise, from the mosfet, in the arduino version used 30Khz to avoid this, does it happen to anyone else???

Merhaba Aka, çoook güzel bir paylaşım olmuş. ben yeni başlayan biriyim. Sizin T12 modülünün kurulumunu pek anlayamadım. Kart üzerinde gösterimini nasıl öğrenebiliriz veya yeni öğrenenlerin anlayacağı şekilde. Ayrıca ben bunu biraz daha düşük voltajda (5 volt - 12 volt)kullanabilir miyim? Yeni başlayanlara yönelik paylaşımlarınızı merakla bekliyoruz. İyi çalışmalar.

4:09 At the moment of the tip being heated by 18-24V from the power supply, won't the input on the OpAmp be the voltage of the power supply? How does the OpAmp "know" the voltage of the thermocouple if it's connected directly to the power supply output like that? P.S. I've built this station and it works. It keeps me up at night knowing that I don't get it. Please help :D

Why i can't find any application on playstore that can open your archive files ? May i know the app that can open .lay6 tipe of file ?

Hi there what green mat do you use? Is it ESD safe and solder heat resistant? Great Video!

Can someone explain to me why the 1n4148 vd2 diode is reverse between the 2 opamps? Pls

can it work with c210 ???????????????

Someone else. Build this schematic? It's really works???Seems fake, because don't match number of resistor and capacitors.. In one image shown a board with 3 capacitor and and in other with 4 capacitors..

It is a PWM circuit without any temperature sensing.That means increase manually the duty cycle until the solder melts in the desired solder point but can not be left prolonged because the next melting will be the solder iron itself.

can I replace the mosfet with another one, I'm having a hard time getting it. thank you

Can you help me do it.

any schematics ?

I m waiting for step up dc-dc converter with switch system of 10 different output system. Plz try to make a video on the topic

There is something wrong with the schematic and the PCB layout that you gave. The PCB is different from what is on the schematic.

resıstan ve sensör ohm ????

Are you from Earth

plz give me diagram link

Its "Vid-Eh-Oh" !!!

Please subtitle Indonesia

Pcb layout please

Mosfet is p-channel !!

T12 soldring tip is very costly

INYONG WIS NGGAWE....MANTUL...???!!!!

in china you can create everything in russia everything can happen
