I'm a big fan of blinky things and with my t-shirt design business going full swing, I wanted to combine the two things. So, about a year and a half ago, I built a t-shirt with an LED array on the front. It was a pretty complex set up using a Raspberry Pi 2 to control a FadeCandy NeoPixel driver board that in turn ran the Neopixel array. In order to control the display, I had a small wireless router set up and I had my Pi and my Android phone connected to my little mobile network. I used the TouchOSC Android app to send commands to the Pi over the wireless connection. It was a lot of stuff to carry considering I had to power all of it as well. I had a battery for the LEDs, one for the Pi, and one for the router.
I didn't do a whole lot of documenting of the project and I've since reused the Neopixel strips in another project. I've put together a quick video of some Vine loops I made when testing the original project.
All that being said, I've started putting together a brand new LED T-Shirt!! Whee!! And... I'll be doing a bunch of documentation this time around.
Stay tuned for more fun stuff!!
