Projects
- Needed a quick NAS, slapped a WD Black drive on a Beagleboard X15.
- A friend of mine needed to keep track of the water level in a rural water tank. Several years later, they needed a replacement.
- Sub-$10 sensor network node - Microcontroller, Lithium Ion cell charger, 915 MHz ISM band FSK/ASK radio. The 915MHz-BCON.
- Thirty-two digit, 7+1 Segment LED display panel. Suitable for DRO applications.
- Salvage an RF module from an Xbox 360 and use it with a desktop computer: a how-to.
- My 1320 lumen bike light project, made from old laptop batteries and spare parts.
- DIY bench-top power supply, made from salvaged and surplus parts.
- A basic 65C02 microprocessor computer on a 4"x3" PCB. Bonus: It fits on top of a Parallax BoE-bot frame.
- 'Low cost' two axis multipurpose desktop CNC table; Parallax Propeller, Allegro A4988 stepper motor drivers, and a whole bunch of aluminum.
Teardown and Tinker
- An in-depth look of the Light L16 camera, one of the stranger consumer devices I've seen.
- Looking to add exactly two Ethernet ports to your computer via USB? You have choices.
- Waited nine months for Starlink, took apart the router on day two.
- After Hewlett-Packard, probably Texas Instruments makes the most well-known graphing calculators. Watch as I crack into a TI-92 Plus, one of their flagship devices from the 1990's.
- Ever wondered what was on the inside of a Mitsubishi OmniQuest ST251 Mobile Satellite Terminal?
- Took a look into the microcontroller of the Nintendo Wiimote with an eye twoard running arbitrary code on it.
- Hey, look what I found! A Kodak Theatre HD Player for five bucks! Let's take it apart and make it do tricks.
- Documenting my shenanigans with a HTC Dream/T-Mobile G1/Google G1 phone
Deep Dives
- A short note on getting an Apple iSight Firewire camera working on Linux. Spoiler: No longer supported.
