PlatformIO has really lowered the barrier to entry for a lot of the more hardcore mcu programming.

Switching gears away from gears to analog electron

Switching gears away from gears to analog electronics. I’ve been working on programming stm32 chips for a bit and ran into the issue where I’m programming a board and didn’t want external power bridging the USB into my PC or have the servo drawing too much current. I hate having to disconnect wires or unplug the USB, so I wondered if there was another way. I bought some SPST DG412 CMOS Analog Switches so I could toggle between USB and external power with a SPDT switch. I was getting fairly close to having it working when I found a way simpler workaround of just disconnecting 3.3V from the programmer. At least I managed to learn quite a bit about CMOS linear switches and transmission gates.

Kinetic sculpture parts for some local artists. This is the longest part I’ve ever worked on. Also I almost never turn stainless. So much learning.
