We made a little mistake when designing it so wires are there just because one chip for case temperature needs to be in the air not on pcb. Everything ealse is the same.
Kind Regards

Gotcha, just wondering. I've been considering doing my own PCB's for a similar system for a while. Glad to see such success.
Are you using the Max6675? I'm still trying to decide on my display ic as well as what system I will use to load over the microcode.
can you tell me the name of the Thermocouple-to-Digital Converter IC?
@n00b of l337
the Max6675 has a range from 0 to 1024°C
Ah thank you, been doing some reading and must have missed the low end number.Quote:

Just use an instrumentation amplifier circuit with the microprocessor's built-in A-D converter for the thermocouples. Then you just need a thermistor for the cold junction - No need to mess about with overpriced ICs.
quality & clean job as always .
Thanks :up:

Not bad at all :D

did you ever come up with a price for these?
No problems on low temps too. =)

Very professional looking.
What's the maximum power the fan header can supply to the condenser fan?
I forgot all about this thread, thanks almighty for making a post.
I'm curious how the thermocouple circuit was implemented, especially considering that it is good for very low temperature. LittleDevil I know this is a product of yours, so I will understand if you don't wish to share this information, but it is something that I am always curious about (thermocouple circuits are a tricky thing to get right).
