Multitouch – making of

After 2 weeks of collecting materials and several days of grinding, drilling and screwing (thanks dad!) I’ve finally managed to build my first multitouch table!

This is what i’ve used:

- Acrylic sheet (635mm x 475mm x 8m) – 80 PLN (23 EUR)
- 2 wooden frames – 120 PLN (37 EUR)
- 42 (3x7x2) IR diodes TSHA5502 – 30 PLN (9 EUR)
- 6 resistors, 6m of cable – 10 PLN (3 EUR)
- Old Logitech QuickCam Messenger webcam – 20 PLN (6 EUR)
- Mirror
- NEC VT470 projector (borrowed from school)
- Power supply from my old PC
