Oh man, this thing looks amazing. No sooner had I soldered pins on the Teensy 3.2 than a newer Teensy 4.0 arrived in the mail. The new Teensy is insanely more capable for the same price and in the same form factor. It’s 10-15 times faster on benchmarks, has 16 times as much RAM andContinue reading “What about the Teensy 4.0?”

My first experiment in speeding up the LEDs is to use something called OctoWS2811 which is designed to let you drive 8 strips of LEDs in parallel. Theoretically, this would allow me to boost the speed of my antenna from the dismal 9 frames per second to a much more attractive 72 frames per second.Continue reading “The OctoWS2811”

One of last years’ projects was a 46′ tall antenna “wayfinder” that we used to find our camp from miles away. It was awesome, but next year I want it to be even awesomer.

This blog is about programmable LEDs, and making them fast and colorful and cool.
