Looking for TC4C board
mg512
I have found that a stencil is mostly useful for speed, and precision for SOIC components (i.e. the ADC and EEPROM). Resistors and the like are fairly easily done by hand. Personally I have had much better results with a hot air gun than with a hot plate, so I wouldn't sweat it too much.

Regarding a through-hole version of the board, I imagine it might be a matter of who would make one. Probably most people who have the skills to design a PCB also have the skills to do SMD soldering.

Also, just to be clear: please feel free to think of my CR3 board as a "TC4 v8.00". My intention with making them available is very much to meet the demand for TC4 boards. It's just that I had my own design already lying around, so I decided to just go with that one instead of whatever older version of the TC4 I could have found online. The board is literally a TC4 with some additional, optional extras. Not that I mean to discourage anyone from building their own TC4 - it's really good fun! But just in case I hadn't made it clear enough what the CR3 was: If you're just looking to get a TC4 without any hassle, that is what the CR3 is there for. I could also include a pre-programmed Arduino if someone was after a TC4C.

Hey I don’t want to hijack this forum. I’m completely new to forums. I noticed y’all hav had a time contacting Jim too. I’ve been wanting to run my roaster off a computer to get more consistent roasts so I gave Jim a call. I bought a ZCD board from him because he had some on hand. He was fixing to go on vacation and he said it would be October before any TC4C’s would be available. I tried calling him numerous times since then with no response. I’m getting desperate. Where can I find one?

I think we've all come to the realisation that Jim is no longer making boards. You're probably best using a TC4 or compatible board and Arduino Uno instead of a TC4C.

The good news is that TC4 boards and other compatible boards are available from forum members here. I've built a TC4 board and will be building some more in the next few weeks.

It indeed looks like Jim isn't in business anymore. I might have been one of the, if not the, last ones to receive a TC4 from him last September. I have since then designed my own board that incorporates a few additional features alongside those of the TC4, and have made those available since a number of people were looking for boards on here. See my separate thread for details:

If you were looking for the TC4C because you don't want to mess with the Arduino etc., I could send you a complete package with my board atop a pre-flashed Arduino - that would be a direct drop-in replacement for a TC4C.
