A t-shirt with a LED strip in the shape of a raibow. The Light emmiting diodes cycle through the colours of the rainbow.

After we finished putting together five-0, my daughter put in a request for her own running shirt:

“Ummm. I really want to have a rainbow on my t-shirt. Bursting out, and with the colours of a rainbow.”

The rainbow shirt is fabricated from 14 APA102 LEDs, and an Attiny85. It is powered by two AA batteries and a DC to DC boost convertor.
