I build the diy relay board circuit and soldered up a compact little board, seems to work great.
I am powering the Raspberry Pi with a regular orbit brand 24VAC power supply and bought a little power buck converter from amazon to help power the relays separately from the Pi. I split the 24VAC from the power supply to the relays and the little buck converter board I linked to. The 24VAC runs directly to the relays for the valves, and the other side is converted to 5VDC for the relays.
Somehow overnight my power supply burns out.
I am not sure if my soldering caused the problem. I noticed once in a while ALL the relays are activated, maybe this condition burns out the power supply if left unchecked for too long? I can't find a reliable way to force the condition, but it never happens when the 24VAC is not connected...
I think my next test is with three different power supplies. Once for the pi, one for the relays, and one for the valves.
Any help or ideas are appreciated!
Thanks,
David
