I’m in the process of building the best desk ever, and my first step is managing power and metering for my AC computer and DC project systems.
My buddy just moved into a new apartment and was forced to downsize his workspaces. As a result, he sold me his partially assembled Zenworks CNC for CHEAP. I immediately set out to get it up and running.
At this point the system needs 120v AC, 12v & 5v DC, and I’ve designed a prototype power supply to deliver just that… And more.
My attempts to build a PWM dimming circuit based on just a 555 timing chip and a power transistor.
Long before Inventables sold an all-in-one controller/power supply for the X-Carve, I was busy making my own better version.
Have you ever been so excited about something, you forgot to take photos? Me too, but here’s what I did capture—
A quick and cheap 12VDC solder hood, made of scrap acrylic, LED tape, and computer fans.
