BlinkenLEDs deutsch

The BlinkenLEDs project (hardware and player for Windows) from HooMair was one of the first 144-pixels-reproductions. The idea was born in a thread of the jaLCDs-boards, where they actually discussed about blinking keyboard-LEDs ([Link]read thread). One thing was certain, the set up of the hardware: 144 Low-Current-LEDs should be controlled from shift-registers on the parallel port. Very soon a tutorial was already available at [Link]BlinkenLEDs.de and some people started, to build a BlinkenLEDs, too. Later on some etch-templates and new software like BlinkenPlayerExxtreme or BlinkenTool were attached. Greyscales are originally not implementated for BlinkenLEDs, but can be upgraded.

BlinkenLEDs PCB


As the wiring of the PCB is quite difficult, Ca$cAde and Meb developed a BlinkenLEDs PCB. The latest version includes minor bugfixes by ST:



1stein has clicked a space-saving PCB, which additionally supports greyscales (for use with suitable software)
