RPI Cooling fan control

Hi !


I was so inspired by this post, thanks !!,  so I did some fine-tuning and documented it in this post https://pysselilivet.blogspot.com/2019/0...ntrol.html

Great , thanks for sharing. .... just a thought as the supply voltage seems to be rather critical for our raspi - can you also show the supply voltage in this NR - how would this be done?

Did a diagram I hope helps. In this case I used a TIP 120, NPN Darlington transistor, since I had a spare.  A 3 Amp 5V powersupply is enough to source, a SDR receiving AIS, direct via the RPi USB port
