This is a "Universal Stock Ticker", made around 1880. My father tinkered with it a long time ago and it's been on the shelf since. I've poked at it a few times, but this week I decided it would make a fun project. The obvious choice for control was an Arduino, but mine were all back at school, so I opted for using an FTDI USB-Serial Adaptor for GPIO. A few MOSFETs I found in my room do the heavy switching, and a computer power supply provides the juice. A little python script takes text and ticks it out on the ticker, just like in 1900. We're missing the original ink rollers, and I didn't have time to make that this time around, so I brushed on some wet sumi ink, which almost works... I'll make a web page with more information, photos etc. ASAP.
