BlinkenBadge is an extremely small Blinkenlights clone that can be used as a name tag or similar. Just in time for the 22C3, the first BlinkenBadge is ready and there is just some more firmware code missing now. :-)
Specifications
- Size: 67,5mm x 48mm
- 144 high-efficiency 1206-SMD-LEDs (Reichelt "SMD-LED 1206K rt")
- Several brighness values (8 or 16)
- ATMega128 microcontroller (the [[BlinkenlightsEnglish][Blinkenlights]] movies are stored in the microcontroller's flash using a special binary file format)
- Transfer of the Movies is done via RS232 (standard bootloader)
- controller is ISP-programmable (solder pads similar to BlinkstroemAdvanced)
- Battery: CR2450 lithium button cell (500 mAh)
- Maximum power consumption: <55mA (all LEDs switched on) --> Battery life (hopefully) >>10h
- Connection of 2 external AA batteries (or 3V power supply) possible for long-term usage
Schematic/PCB layout
- Schematic v1.0 [EAGLE]

- Layout v1.0 [EAGLE]
- Layout top (LEDs) v1.0 [PNG]
- Layout bottom (the other stuff) v1.0 [PNG]

Software
- Firmware v0.1 - just plays black-and-white movies
- Konverter (Perl) to create an assembler file from BLM-movies
The blinkenlights movies must be converted into a special format with the converter first. The resulting file (movies.asm) is then included into the firmware code, so the program must be reassembled if you want to change the selection of movies. Converter invocation:
$ ./bbadgeconv.pl Movie1.blm [Movie2.blm [Movie3.blm [...]]] >movies.asm
or for all movies in the directory:
$ for f in *.blm; do ./bbadgeconv.pl $f; done >movies.asm
The converter only works with black-and-white BLM movies with 18x8 pixels!
