Box breathing box
I wanted a device for box breathing, the technique where you breath in/hold/out/hold for 4 seconds. A device that wasn't a phone or computer. I built one, out of wood, plexiglas, metal, transistors, and a tiny bit of code. Then gave it the photo studio treatment, shared the code, and wrote about the experience.
Model 100 upgrade
I've designed a new mainboard for the Tandy / RadioShack TRS-80 Model 100, one of the very first tablet computers. The machine turns thirty years old this year and, amazingly, many of them still function! My upgrade replaces the Model 100's 2.4 MHz 80C85 with the more modern 16 MHz AVR AT90USB1286 on a Teensy++ and adds new features like VT100 emulation and the potential to increase the storage from the original by a factor of one million.

Powershop.co
Powershop search engine for PC components (like motherboards, CPUs, etc). My basic plan was to create a tool like diskcompare that would work for all types of components, as well as an attempt to come up with a modern HTML5 UI that would let you view and filter data the same way you would in a spreadsheet or database browser. Right now it works for CPUs, GPUs, RAM, Motherboards, Monitors, Hard drives (including SSDs), USB sticks (and flash cards), Monitors, Cases and Fans, as well as Laptops and Tablets.
The front-end was done entirely in javascript (about 5k lines of JS before compression), and no HTML is generated server-side, instead plain HTML is sent and the javascript code requests JSON objects for everything else. [more inside]
