What are some DIY electronics gift ideas for the holiday season?

[axmls]

Hello all

I'm looking for some cool Christmas gift ideas that I can build for friends and family at a fairly cheap price (~50-70$ assuming I've already got basic components/hardware) using electronics/microcontrollers. Most DIY sites I see after a quick Google are non-electronics oriented, so I was wondering if anyone here had any brilliant ideas or could help me out with figuring out some good gifts to build for any demographic.

Also, hardware suggestions are accepted too. Right now I have the most experience with Raspberry Pi/Arduino/PIC microcontrollers (in that order).

Thanks for any inputs
