DIY Ascom Fan Controller ....

Recommended Posts


I have been building again ! Some time ago I added a PC fan to the back of my 200PDS to help with dew prevention. The fan is controlled by a PC fan speed controller. The problem with this is I have to go outside to turn it on and off, I am inherently lazy 😉

I decide to build a remotely controllable fan. The fan can either be controlled manually via the rotary encoder or as a switch in ascom. Hopefully tomorrow I will get it all in a small box and bolted on the scope 🙂

Nice idea Alex, I've been wondering about a fan on my 250Pds on and off.

Thanks Mark

Its all finished now and in a nice box. I'll do another video when I get 5 mins.

Works great from NINA and SGP 4 🙂

Only annoying thing is you cannot turn off a PWM fan without killing the power to it, hence the relay
