So, I am building a new 'gizmo v3' using a gutted out PC case. This one has 12 separate plugs made by breaking the tabs on 6 120v wall sockets and controlled by 1 Kuman 8 channel controller and 1 Kuman 4 channel controller which in turn are controlled by a Raspberry Pi 3 B+ running Raspbian Deb Stretch, Apache2, php7 and Python 3. I gutted out the PC power supply and mounted a 120v 15 amp wall socket that splits off to supply power to each controller using a 12 gauge copper wire. The RPi power supply plugs into one of the socket of the input power plug. Each of the outputs on the controller transmits its power using the 12v 22 gauge PC plugs. If my calculations are correct, each string of LED Christmas lights drawn 0.34 amps and the 22 gauge wire can handle 0.92 amps, so I should be able to daisy chain 2 strings of lights per socket.

A 15 amp wall socket can handle 12 amps and that my overall usage will be 11.1 amps (8.6 amps for the lights and 2.5 amps for the RPi). Does this sound about right? Or am I missing something?

can you post a photo of this setup? kinda makes me worry.

There is a aquarium reef controller very similar to this called reef-pi that you build yourself.

Why would you worry? The wire guage and amp are all well within specs,
the box is properly grounded and using a multimeter on each channel shows
well under limits and the core temp is running at 36.6 c

okay, looks safe. if you plug it in and it doesnt blow up, it's good.
i wouldnt have stripped back the wires that far, though.
it does look weird but as long as it works.

It looks less weird with the side panels on, as far as the wire stripping I used Liquid Electrical Tape to clean it up, and yes, it does work very well, it controls 12 channels remotely via a web interface I scripted or timed channel events or it even takes voice commands via the STT/TTS scripts I wrote; bluetooth speaker and headless ... my Tab 10 is the monitor ... anyway, thanks for your interest,

Merry Christmas

Ya, there are a lot of projects that can be made using an RPi, one thing I'd like to get for mine is a UPS power hat and switch with led and power meter ... cheers brah

i used to build and repair cystoscopes and a device for trans urethral needle arberation [and other things for the past 24 years].

usually the rule is that if it works, it works. and dont spend too much time working on something. the more you work on something tiny and delicate the more you can mess something up.
