Arduino based incubator - hangs - SOLVED - power supply issues

Good luck... BTW those eggs look smaller than the ones in Jurassic Park smiley-wink

Yes, fortunately. When they are 5 months old they still need to fit in my homebuilt plucker.

Before you rule out power issues completely, consider whether the mains power you're getting is ok. I recall another troubleshooting thread where the eventual problem turned out to be a very old fridge. When the compressor kicked in, it caused all sorts of issues for the electronics plugged in on the same circuit.

wildbill, thank you for that remark. Especially the part about the old fridge, because:

One likely culprit is standing there! But I noticed before the lights flicker heavily when inductive loads get switched on...
I placed a 2200 µF capacitor parallel to the output of my power supply and voila. No more reboots for the last 4 days.

Thank you so much!
