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.

I go with this design to prevent complicated carpentry work that I'm not confident about. Instead... I still do carpentry work I'm not confident about, but at least it's simple! Also, I get to buy a new toy :P

Cabinet Light Project - Part 1

I really want to replace this terrible light fixture under my cabinet:

Cabinet Light

It shines light right into your eyeballs and give you a headache. Not ideal.

  • A nice wooden housing
