STM32 Soldering Station

Post by .rpv » Thu Sep 29, 2016 8:27 pm

Hi there, so I'm adapting this project: https://hackaday.io/project/3417/ to the "blue pill", I tested it on an arduino pro mini and worked well so I decided to this be my first project on the STM32 platform, so almost finished and just missed a few things that I can't use on this platform like:

-the watchdog library.
-the TimerOne library.

This is the schematics I'm using:

It's pretty much the original project and this is a few photos:

Also I've a few doubts about the pin-out of the STM32, I tried to use the OUTPUT_OPEN_DRAIN output on the pin PB4, that won't work, so instead I used the PA9 as PWM_OPEN_DRAIN, so is there documentation about when (what pin) you can use this output types?

So far seems to work, I noticed an 10º-20º overshoot of the set temp but then stabilizes.

I like this platform a lot! :D

Thanks to you for porting this platform to the arduino IDE.
That was awesome!.

Its not all my own work ;-)

Much is owed to Leaflabs for their original work, and also to all the other community members as well.

Well, thanks to all people involved on this platform, as I said before, it's just awesome!.

Here are a few extra photos (if I'm abusing please said it and I'll stop 8-) ).

I made a small mistake on the graphic code and got shorted, it's supposed to be the half of the display.

love it :)
looks like a fun project :). Was it hard to get the temperature readings of the soldering iron correct?

Looks great, I always wondered how hard it would be to make a control board for a soldering iron!

I'm curious, how does it perform in practice? Does it take long to get up to temp? What kind of stuff can you solder with it, would it work on some bigger through hole parts with bigger thermal mass etc.? Is it better/worse compared to the el cheapo' Hakko clones?
