LED Track Jackets

Seven LED track jackets

I think I had this idea of stuffing LEDs down the stripes of track jackets many years ago but the technology wasn’t there at the time. I was probably assembling my LED matrix hoodie and wanting a way to keep the LEDs captive and straight. With the package size of addressable LEDs shrinking we now have ones that are small enough to to fit inside factory sewn stripes. My friends and I have built a few of these now and I wanted to share some of the techniques we use to make a hopefully robust glowing jacket. (tl;dr at the end) Continue reading

Teensy LC Breakout

Teensy LED breakout boards assembled

I work with Teensy dev boards and LED strips fairly often. Connecting the two to each other seems to be something I’m constantly reinventing. Here’s my most recent attempt at a board I could use for both quick prototyping and permanent installs. While I mill a lot of prototype PCBs, this is only the third board ever that I’ve had professionally manufactured. This time via Oshpark. Continue reading

Robotic paintball turrets

Hoppers rigged

I got to work on an interesting project for Toyota’s Make Your Mark campaign for the new Corolla. We built 2 robotic turrets with 3 paintball guns on each. The pan and tilt movement is driven by 2 Tormach rotary tables; these usually act as a 4th axis on a CNC mill. The paintball guns already had solenoid driven triggers but we adapted them for remote control. We also monitored the gun ball sensors to determine if a paintball was in the chamber. The guns are driven using G-code like any CNC machine. You can see a video of it in action below where it’s painting every time it receives a tweet. More photos from the event are on Flickr.
