Viliam's TC4 and ZCD boards in action


Quoting Jan van der Weel from the above blog link:
A few months ago we wanted to order some extra TC4 boards for our roaster. This board is an arduino shield that can handle 4 thermocouples and takes care of precise temperature measurement. During the order process we had a problem. We could not order them anymore from the mlpg-website. All the “order buttons” seemed to be disappeared and mailing them gave no response. But somehow the universe came with a solution. A few weeks ago we got in contact with Viliam from Slovakia. He also needed TC4 boards for his projects and he told us he had decided to produce the TC4 by himself. In case he was succesful we could order from him. A few weeks ago he told us that he had succeeded and he would send us one of his first production TC4 v6.01 board and his Zero Cross Detector (ZCD). The ZCD is a device that detects the sine waveform transition which is needed to control the airflow of our AC Blower. Today we tested his boards and it all worked perfectly. Many thanks for Viliam to keep this valuable arduino shield alive!

The TC4 boards are hard to find these days but our friend Viliam has set up a very small production line. He sent us a TC4 v6.01 and a ZCD (Zero Cross Detector) which we test fly successfully here:

Hey! I've been following your roasting project now for a while and it's inspired me to start my own roaster project.

I've got most of the hardware figured out, got an arduino hooked up with artisan and was already able to do some test-roasts.
Now in order to proceed I would need a tc4 board, but unfortunately thetwebsite seems to be offline for the last month and I can't seem to find it anywhere else.Is there any chance you could get me in contact with Viliam and I could buy one off him? That would be really helpful!

Thank you guys so much for documenting your project, it's been hugely helpful.
Please keep up the great work!
Ps: I'm based in Austria ;)

Villiam seems to be offline -- we found another source. Email me at frans@goddijn.com and I will see if I can connect you.
