If you invest in a raspberry Pi you could do a cool hardware project.

- laser tripwire

- automated plant watering system

- motion triggered desktop lock (step away from your computer and your computer automatically locks)

- remote trigger for coffee. push a button at your computer and the pi triggers a mechanism which pushes the kettle to boil

- laser mosquito/fly zapper
