One interesting thing about them is that AD8628/AD8629 opams are used instead of microchip ones.

better than a microchip in terms of characteristics.

Yes and no. Microchip ones have a specified common mode input voltage 0.2V below lower power rail. Analog devices ones does not.

How about Max6675

1/4 power also works as a charm.

All worked from the first try, and I am a bit suspicious. :) C210 works muuuch smoother on 1/4 power on 24V. It now only jumst to +/- 1-2 degrees from the target.

Yes, that's it, but the sources from Tindie, where I bought it from, are the sources from the first pages of this thread.

There are so much forks on Github, that I cannot find the right one.

PS: Looked at all the forks of all the repos on GitHub - didn't find it. There's a fork where two of the functions are added (for the button swap and for the sensor filtering), but this is not the one that the controller came with.

Hi Sparky, good to see you back man. I have sent you a PM.

Latest version of all will be posted on this git repo:
https://github.com/sparkybg/UniSolder-5.2

Several notes and so on, you can find in this linked repo (Valerio made a great job):
https://github.com/valerionew/unisolder-notes

Only "with bootloader" hex is rebuilt with new things, here:
https://github.com/sparkybg/UniSolder-5.2/blob/035d798bdf19e8c1dd8bef4f32440eda3c508949/software/front/US_Firmware.X/dist/PIC32_with_bootloader/production/US_Firmware.X.production.hex

The new features are:
- 1/2 and 1/4 power (no need for lower voltage transformers for small irons anymore)
- JBC C105 / C115 iron profile is added

Small irons (C210, microtweezers, C105, C115) are working much smoother now.

Tested only with 24V toroidal transformer, so use with caution.

So is this the version with button position control and "wake from deep sleep" functionality?

No

Thought so, thanks for confirming. It would be great if this functionality could be added to the official FW sometime, but I understand it's a lot of work without the source code.

I've noticed on the Tindie there is a photo of fully assembled station, and it is exactly the same photo as 4nthonylin published some time ago here, http://dangerousprototypes.com/forum/index.php?topic=7218.msg71157#msg71157, so may be he knows something about those features.

Photo is likely ripped but maybe

New firmware is uploaded to Git repo:

Added features:
- Added PACE TD200 Blue
- Menu rotates.
- Menu options rotates.
- Display rotation option (0, 180deg)
- Wake from standby option (OFF, Key, Holder, Both)
- Button swap option (+/-, -/+)
- Display brighness option now works.

Fixed bugs:
- Hot tip heater detection now works - no need to wait for tip to cool down any more.

The repo is here:
https://github.com/sparkybg/UniSolder-5.2

Hex for standalone:
https://github.com/sparkybg/UniSolder-5.2/blob/main/software/front/US_Firmware.X/dist/PIC32_Standalone/production/US_Firmware.X.production.hex

Hex for bootloader:
https://github.com/sparkybg/UniSolder-5.2/blob/main/software/front/US_Firmware.X/dist/PIC32_with_bootloader/production/US_Firmware.X.production.hex

Now if anyone can give me a link to sources with "sensor filter" option, I will add it also.

New version uploaded, added holder sensor filtering (although IMHO this must be implemented in the very sensor, as is done in the MCU of the original IR optical sensor).

And some updates on what's shown on the display:
- ACF = AC, full power
- ACH = AC, 1/2 power (you can see this on JBC Microtweezers on 24V)
- ACQ = AC, 1/4 power (You can see this on smaller irons like JBC C210, C105, C115 on 24V)

DCF, DCH, DCQ - same for DC power.

And again - PAY ATTENTION WHEN YOU ARE USING DC POWER OR LOWER VOLTAGE THAN 24V. This is tested ONLY with 24V 6A toroidal transformer as power source, which I strongly recommend as the best power source for this project.

I don't know when I will be able to test it wit DC source.
