TinyCylon v0.3 Larson Scanner
thingiverse
The TinyCylon, measuring at 49.5mm x 10.5mm, is a compact Larson Scanner featuring 12 LEDs. It operates via Charlieplexing and utilizes only 4 pins on an ATTiny85 microchip. Space-saving SMD components, including 1206 SMD LEDs and 0805 SMD resistors, are employed to maintain its minuscule size. KiCad offers the board's schematics for review. As a kit, it's currently available on Phenoptix's website; however, it remains a work in progress. To create your TinyCylon, you will require 12 color-coordinated 1206 SMD LEDs, four appropriate 0805 SMD resistors (1.8V to 5V), and an ATTiny85 SMD SOIC chip programmable via an Arduino Uno with a PROTO shield. Soldering skills are essential for assembly, and detailed instructions can be found at Phenoptix's blog.
