Please Do Not Water This Tree

About two years ago, I made a little LED tree as a gift. An extremely simple design with 17 white 0603 LEDs soldered to magnet wire, twisted and bent to make branches, and combined them to a small LED bonsai. Electrically, all LEDs are wired in parallel and connected to 4.5 V via an LDR. This lets the tree react to the ambient brightness and helps it to great battery life. Read more →

A Better STM32F0 Prototyping Experience

This project started when I was particularly annoyed by existing development board options and cheap Chinese PCB prototyping services were starting to emerge. Thus, the path forward was clear, but let’s start with the problems I was trying to solve. When I’m talking about ‘development boards’, I mean boards like the Teensy models, Feather variants or blue pill: a PCB based laid out around a microcontroller containing very little extra circuitry; a ‘least common denominator’ of typical projects using that MCU, if you will.
