How can I contact you via email?

Can you send me a mail somehow? I'm not fimilar with github.

Thanks.
Niki

Hi Niki, I think we can chat in this thread if you like.

[nikifena]

No problem, but I prefer to mail or FB... or whatever.

Anyway. I will modify my idea for the SCH and I will try to send it here.

Thanks

The original hardware designs were done in Altium Designer. It looks like @PaulusSmallus made a fork of the project and used KiCad.

[nikifena]

I have AD too and I like it and I use it. So I feel comfortable with it. I'm not fimilar with KiCad, but I can try it in the future.

[timothyjager]

It sounds like you will want to fork my project so you can commit your changes to a new repo that you control.

[PaulusSmallus]

If you look at https://github.com/PaulusSmallus/JBC-Soldering-Controller/blob/master/Hardware/MainBoard/output/main.pdf
you can see how I connected the extra channel up.

[nikifena]

Yeah! something like that.
What do you think about adding another soldering iron?
this means another as1118 and VN5E010?

I can make the PCB design as I told you, but I'm not familiar with coding

[PaulusSmallus]

The tweezers are essentially 2 soldering irons. So you would have a choice of 1 tweezer, or 2 normal soldering irons.
If you wanted more than that, I would use 2 processors. Driving from one uP might work, but it will not be worth the time.

I would like to ask a question.

How to calibrate the temperature?

How to adapt to different soldering heads?

[PaulusSmallus]

I calibrated the temperature using another thermocouple to measure the temperature of the iron. I then adjusted the code with the measurements.

Do you mean different tips (i.e. different shaped tips)? or different irons (i.e. trying to tell the difference between a PA120 and a T245)?

[liuweisword]

I use this to calibrated the temperature.

but,when I change the different tips the temperature need to cali again.
some tips is big, some is small. so the temperature always need to calibrated.
Can I set a Auto Calibration function for all the tips？

[PaulusSmallus]

Sorry for the late reply. I have been thinking about this.
What you linked to is the sort of thing I used to measure the temperature of the iron.

I don't know if this will work, but I think its worth a try (even if it is just for the fun of it).
The difference between the tip temperature and the thermocouple temperature is going to be proportional to the power going through the tip. Assuming that that this proportionality is roughly consistent between tips, you might be able to get a more accurate tip temperature by taking this error into account.
I hope that makes sense.
