Failures, learnings, and final light (Cabinet Light Pt. 6)

This is, I hope, the last entry in the cabinet light saga. While it was fun to tinker with the programming of the first one, a number of issues arose that were annoying to deal with. With the learnings from the first "prototype", I created a second version that was easier to build & should be MUCH safer.

Which one looks safer to you?


New Version

So what happened with the prototype?

Repairing a P4400 Kill A Watt meter (aka 1800-Watt meter)

Recognize this thing? It measures your power usage and is somehow always more expensive than you expect. I definitely blew a fuse or something in mine drawing a lot of power - time to fix it!

P4400 Kill A Watt power usage meter

I learn after the fact that this is only designed to handle 15 amps, which at 120 volts is 1800 watts! That's a lot of watts.
