Playa Bike Build Tutorial: 3W LED Fiber Optic Tail
We’ve got some new content from Erin St. Blaine! Check it out:
This summer I’ve been working on converting my old mountain bike to a fabulous Festival Mutant Vehicle with lights, fun fur, and gorgeous paint colors. (See Previous blog post).
This week, I’ve added a 6-foot tall fiber optic “tail” to the bike, with around 50 strands of fiber optics and light pipe, to make a very visible and lovely tail flag for the bike. I’m using a Feather M4 Express with a PropMaker Wing added, connected to a super bright 3W RGB LED. The fiber optics are easily removable for transport, and they’re really bright and easy to see, even in the daytime.
The RGB LED uses Circuit Python to slowly shift through a rainbow of colors, lighting the fiber optics with a lovely, buttery smoothness. The whole assembly is really well protected from the elements — I even dropped the battery pack, LED and microcontroller into the pool to test it and it kept working even underwater!
If you trick your bike out for a festival this season, be sure to come by Show and Tell on Wednesdays, and show off your fancy ride!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
