4 Channel Thermostat using PID loops

Might have a look through the code as I'm rather rusty lol. But hoping to write most of it myself to dust off the cobwebs and it's also a good way to fully understand what's going on etc. But might end up still asking a few q's etc which is why this forum is cool as so many pol willing to help etc.

Well I received 6 PCB's that I had made by PCBWing in Hong Kong, which I must say offer a fantastic quick service even on the "economy" option. I chose the 7 day turn-around, and the boards were received around 12 days after placing the order.

Here's the 1st board, not quite completed, but you can see the quality of the PCB. I'm hoping to get the first "production" unit complete in the next couple of weeks, funds permitting. I've already had people on the reptile forum dropping me PM's with offers to purchase it... - Just need to resolve the coms issue in the firmware first !

Great post! It must be cool to have a history showing your project going from start to finish. Just curious, did you end up using the Triacs and Optoisolators for cost, size or both? I have a HV control project and I am considering the difference between the two. Thanks.

Hi,

Yes I opted for the isolators and triacs for both cost and size.

Has the incPID_mc.pbp file been modified?
I can see several commented lines.
Has Henrik posted this file somewhere on the forum?

As far as I'm aware there was no modifications since the original one posted at the start of the thread. Here's the version I have used in all subsequent builds (change the TXT ext to pbp)
