Got a Teensy 4.1? Want to use it with FastLED? You’ve come to the right place. The Teensy 4.1 is an incredibly powerful microprocessor at a very reasonable price, and FastLED is still one of the best libraries for driving WS2812 type addressable LEDs from Arduino type projects. Paul Stoffregen, creator of Teensy, has aContinue reading “Using Teensy 4.1 With FastLED”

For the future Turtle Antenna, I’m using 16 of these “flex led” strips. Each strip is 5 meters of WS2815 in a nice IP68 frosty silicone sleeve which creates beautiful, diffuse pastel colors. They are 60 pixels per meter so I’m using a total of 4800 LEDs. If you asked me a year ago IContinue reading “Teensy 4.1 is Amazing”

I have been experimenting with various ways to build power injection cables for long runs of LEDs that will be outdoors in suboptimal conditions. Here’s what I came up with, all using parts easily procured from Amazon. This is the power supply I chose. I like it because it is already reasonably weatherproof. I haveContinue reading “Power Injection”
