The PCB (Christmas) Tree (#P32)

Epiphany has already passed and St. Knut’s day is next Wednesday, it’s about time to stop being lazy and get the Christmas tree out of the living room.
Well, yes, but not the usual way. As shown previously, it’s not an ordinary tree. It’s green and it has fancy little lights all around, but it’s also containing significant amounts of lead and it needs a PoE port to operate.

Meet the PCB Tree.

Made from scrap circuit boards, random bits of wire, leaded solder and a couple of Chinese ingredients, it’s a wonderful Christmas abomination that sat the entire last year in my office and received a significant addition in early December 2020. […]


24V to 5V 10A 50W DC DC Converter Regulator Car Step Down Reducer 24V to 5V 10AMP Daygreen CE Certificated (WHL #46)

Overengineered parts from China aren’t really my cup of tea, but this is for an upcoming project with power-hungry, rotating AND rusty plates, so I figured I would use something up for the task…

…and I don’t think I paid that much of a premium for it. So today’s item is a step-down converter model “D121” rated 10 amps at 12V, with 15-32V input voltage. Price was 2.86€ at the time; contrary to the usual item on this site, this was without shipping cost. […]
