  • Name8-bit port status indicator
  • Bymadworm
  • There comes a time when you just don't want to wire up a lot of LEDs on a breadboard anymore. It was fun the first time, but that exhilarating feeling soon went away. This little board just plugs into your breadboard and that's it. All resistors included. It even works in common anode or common ...
  • NameBlinking LED
  • Bykurt
  • Make an LED blink with this simple circuit. By using a 555 timer in astable mode, a square wave is generated. This square wave is output to the LED to turn it on and off. The LED blinks about 3 times per second with the values given in the schematic. The blinking rate can be varied by changing th...
  • NameLED Square - PT4115
  • Bymadworm
  • Small, daisy-chain-able LED board with integrated PT4115 buck LED driver. It's a small and simple project, quite suitable for getting started with surface mount technology. The schematic is strongly based on the PT4115's datasheet. It runs with 24V and only takes about 100mA. Total light output...
  • Namere-fabrication unit.
  • Byarduinopi
  • To start off this is just a concept at the moment that hopefully can develop into something, not a working bit of hardware.I'll break the concept down into two parts deconstruction and reconstruction. The idea is to create a unit which can break down a modern electronic piece of equipment into, a...
