Having said that, I pretty quickly came up with a list of ten or so things I'd like to do, from my own ideas or inspired by things I read on the web, for either the Pi or the Arduino:
- Play with RISCOS. See if !Draw is as good as I remember it to be.
- Garage door opener. More exactly, something which will close the door after some length of time, in case I go away and forget. Ideally with remote monitoring.
- Remove monitoring for door locks. The house alarm will go off if they are open, but it can't detect if they are locked.
- Household web/media/backup server.
- Temperature monitor, air quality monitor. More generally, a sensor board that I could carry around with me and upload data later on.
- Household power consumption tracking.
- Simple remote communication using off the shelf LEDs based on Dietz's ideas (http://www.forth-ev.de/filemgmt_data/files/TR2003-35.pdf).
- Remote lighting control, so I don't have to get up from my desk to turn on the light.
- Scanner replacement by hooking up a camera over USB. Recognize when a page has been placed under it, and take and correct an image automatically.
- Remote or timed dog feeder.
- Oscilloscope. Low frequency, but maybe better than the one I built using an Android phone.
The first thing I am working on is the sensor platform. More on this soon.
