  • I've updated an old design of an 8-RGB-LED ring with dedicated constant current LED drivers and better firmware implementing Binary Code Modulation (BCM), which provides 6-bit depth per color and low cpu utilization and individual control of the LEDs with double buffering. Oh, and it's darn bright!
  • NameScavenger Hunt Beacon
  • Bykurt
  • Use this beacon to broadcast secret messages with infrared light. Only people with the Scavenger Hunt Beacon Decoder can read your messages. Place a couple of these around your town and have each one broadcast a clue about the location of the next one.
  • NameScavenger Hunt Beacon Decoder and AVR Programmer
  • Bykurt
  • Use this to decode the messages broadcast by a Scavenger Hunt Beacon. The messages are displayed on an LCD screen when the Beacon's IR beam hits the Decoder's receiver. This project also doubles as an AVR Programmer Shield for an Arduino.
  • NameMono VU Meter PCB
  • Bykurt
  • A VU meter is used to display the loudness of an audio signal. This open source VU meter lights up ten LEDs to show how loud a mono audio signal is. Two of these can be made to show the loudness of each channel in a stereo signal. This circuit is similar to "Mono VU Meter Breadboard" except it is...
  • NameArduino Hardware Reset Circuit PCB
  • Bykurt
  • This circuit uses one pin to let you reset your Arduino in code. It pulls reset high for a couple milliseconds to ensure the Arduino has enough time to complete its reset cycle. This circuit is similar to Arduino Hardware Reset Circuit Breadboard, but it uses a PCB and requires soldering skills t...
