When we last saw the Decagon Light the scale model wasn’t functional… Well, it is now functional!

I spent a bit of time at Kenilworth Open Studios getting things wired up and writing some code. I wrote a bunch of functions to run different patterns. Each function can be called with two parameters, the delay (which specifies how long the light is on) and the number of loops the pattern should run. Right now there are just four functions, but they can be called differently, and put into iterative loops. (I’m sure I’ll write more as this project progresses.)


For this test I’ve got the DecaLight powered by a Teensy with one of my Teensy BOBs. There’s also a USB battery pack from Brown Dog Gadgets supplying portable power. The final version will probably use the Teensy but use an AC adapter for power.

I reused a bunch of JST connectors that were chopped off some other wires to plug the LEDs into. There’s also plenty of pieces of wire and heat shrink holding it all together. At some point maybe I’ll build this into a much nicer looking unit.

Teensy + BOB

The combo of an OSH Park purple board with the SparkFun Pink Teensy 3.1 (Anouk Edition) makes this one of the most colorful PCB project I’ve worked on yet.

Here’s a quick video of the light in operation.
