Wall clock/weather info/etc, based around the weird plasma display I've picked up at an auction.
This project has high voltage, which could be lethal!!
The display comes from a bus or a train, supposedly.
It has the following labels on the PCBs:
- Morio Denki 6M06056 (the 8085-based control board I wasn't able to get running)
- MD 16101DS-CONT82 06 (the actual framebuffer/drive board)
- MD-24T-ADT (2) 8201 (the boards on the plasma tube itself)
Despite using a standard "HDD" Molex 4-pin connector for the drive board power, it expects +160V on the pin where normally +12V would be supplied. Take care not to mix up the power supplies. (Plugging in +12V into the plasma board doesn't seem to damage it. Plugging in +160V into an HDD, on the other hand...)
