Hi,
Could somebody who knows about electronics and programming please make a prototype bitcoin price ticker:
http://www.instructables.com/id/Make-a-Bitcoin-Price-Ticker-almost-from-scratch-us/Preferably wireless, so it can be put on a wall or wherever. Additionally, allow to set a "limit," that when the bitcoin price drops below the limit, trigger an alarm sound.
If this can be done and sold for ~30$, I bet it'd turn into profit. I'd certainly buy it. In the example above, the components alone cost $60, and that's too much...
It wouldn't be that hard to make using Arduino. Only thing is that the components would cost over $30 by them selves. I think $100 would be a more reasonable price.
