How do I make a simple dc constant temperature controller
« on: July 27, 2018, 08:52:33 pm »
I hope that one of you can help me constructing a simpel diagram:-)

I need to keep the temperature on a heatsink at +25 degrees celsius +/- 0.5 degrees.
It is to keep some IC chips at there optimum temperature the whole time.
If it is possible, it could be fantastic if a dual color LED could change color from i.e. green when inside the allowed temperature and maybe red when outside.

Hope that my explanation is sort of clear.
Even if I appear online is it not necessary so, my computer is on 24/7 even if I am not on.

Your initial question is too vague. You need to expand on your requirements a bit.

How are you measuring the temperature of the heatsink? Do you just plan on sticking some sort of a sensor on the heatsink?

Are the ICs you plan on keeping at 25C heating up on their own when they are in operation? Or are you looking for an Oven controller circuit? If not are you looking to control some sort of a fan?

Then you'll need both a cooler, especially this summer, as well as a heater. A thermoelectric cooler/heater is probably the best way to go. To change from cooling to heating and vice versa, all that's needed it the direction of the current to change.
