The Spikenzie Labs Solder:Time Desk Clock is a fun through-hole kit to solder together. It includes a snap-together lasercut acrylic case with a really nice red tinted screen that increases the contrast on the 20×7 red LED matrix. Plus it is totally hackable with quite a few unused pins available for expansion (like Holly’s sunrise alarm clock).

The kit is available from Adafruit and I’ve written more information on information on programming custom firmware for the Arduino-compatible ATmega328P that is the brains of the clock.

If you’ve ever been running at night in New York City, you know that it can be dangerous, especially if other people can’t see you. This jacket was my attempt to not get flattened by a bicycle at night. Of course, I could have just bought some plain running lights, but what fun is that? Not only does this jacket have seven awesome flashy modes, but each mode responds to my heart rate!

Since my Garmin heart rate monitor uses the ANT protocol, I could easily intercept the heart rate information for my jacket. I used a Teensy and an ANT transceiver to control two LED strips based on the current mode selection and the current heart rate. The jacket is powered by rechargeable battery packs.

My first run with the jacket was the 2013 New Year’s Eve midnight run in Central Park. Since then, I’ve worn it to a few races and even to a tech talk. The full build out details can be found here.

Adafruit FLORA and Neopixel ring

Next weekend at NYC Resistor we are teaching a class on the Adafruit FLORA and Neopixel. These round Arduino compatible controller boards are a great base for wearable projects like watches, jackets and neck ties, as well as holiday decorations. Bring your laptop and we’ll teach you to make the LED ring blink with patterns of your own design. No prior programming required. The class fee includes a FLORA board, batteries, cabling, 4 RGB LED pixels and a 16 RGB LED ring.
