I've been building things from electronic waste for years now, for more examples visit my site:
Turn three dead computers into a wall lamp.
needle nose pliers
drill & bits
3 computer towers - you can find obsolete electronics at local recycling facilities or businesses if you don't happen to have a surplus of electronics.
- or ask a neighbor - around 2/3 Americans have dead computers taking up space in a closet.
16 gauge wire
wire frame/shelf (from closet organizer)
3x light socket (< $3ea)
3x cfl bulb (bulk $1ea)
1x small light socket (+ cord in my case / as-is ikea $1)
1x small cfl bulb ($4 2pack)
15' extension cord ($2 ikea)
If you can find an old radio, they have great capacitors.
Please DO NOT attempt this unless you have some experience with basic electrical wiring.
