Post by dorf » Sun Feb 05, 2006 3:29 am

I found car Heater fan controller in NUTS & VOLTS Magazine December 2005.page 13.

But problem is that i do not know whatkind capacitors are.
47µf is electrolyt capasitor that i know. i can only guessing that rest of them are "caramic" and "film capasitor", what is what, that is mystery.

there is -20 celsius out at this moment,need some heat in car.

Hi Dorf,
I don't think the type of capacitor matters too much in this design. The smaller ones, 2nF7 and 10nF, I would suppose is ceramic and the 330nF is a film type. The main issue is to get the values correct. :D

Please note that the input and output terminals on voltage regulator 78L05 is reversed. The input should be connected to the +12V. 8)
