Back in October I was thinking about how I might build a Space Station visibility indicator. Yesterday I ran across a similar idea at ISS Above, and it got me thinking some more about how I would implement my own ISS appliance. My ideal device would be:
- small form factor, approximately 10 cm (4 inch) cube or smaller
- completely wireless, i.e. battery powered and using wireless communications
- simple and intuitive to operate
- relatively inexpensive to prototype, hopefully under US$50
I could meet most of these objectives with a Raspberry Pi model A, but batteries wouldn’t last too long. So I think my first prototype will include a power feed.
One of my other projects includes setting up ZigBee mesh networking. Once that’s done, I may look into a fully wireless device using an XBee/ZigBee powered by a LiPo rechargeable battery.
