Avete un vecchio scanner da tavolo e non sapete cosa farne? Ebbene, c’è qualcuno che ha pensato a voi.
Questo pazzoide che va sotto il nickname di Sprite_tm ha estratto il sensore ccd di un vecchio scanner da tavolo e l’ha usato per trasformare un monitor normale in un pannello multitouch.

He extracted the single-line CCD and mounted that below the display. He then attached five LEDs above it to shine light down. When his finger touches the screen it casts a shadow on the CCD and, with a little (probably a lot) of custom software he’s able to triangulate the position of the touch. The system even works with multiple fingers, though we’re guessing should they overlap vertically the system might get a little finicky.
