Hi Alun I have made that project and it works with the 230VAC, I think the DC was just an error. The fan should turn on @ approx 40

If I could design one,I would but I don't exact know how I would do it.That's why I started this temp control project.And start from there to go on and change to my needs, but it's not so easy :-\ If you would have any ideas, they're welcome

How much should I change it you think? And what would be the effect?

Hi here is the link http://www.electronics-lab.com/projects/motor_light/025/index.html The problem is that schematic is made for 230VAC And I don't have any DC availble

Hi I have made the schematic of the temp controlled fan. It works, but here is my question. You can set the starting temp of the fan. But is it also possible to tell @ a certain temp to stop the fan?
