  • NameRGB LED RING V2
  • Bymadworm
  • 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.

  • 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...
