Hi folks !
This is yet another attempt to make a laser projector. This device records the motion of your pen using IR mouse chip ADNS 2610 chip from AVAGO and stores it in RAM of P89v51rd2 (1kb) .And can reproduce the X-Y coordinates with a accuracy of 1mm ,technically the mouse has an resolution of 400 cpi (count per inches)which is more than sufficient, delta x and delta y registers are continiously read and displacement if found is stored in RAM .The current prototype can record 40 inch motion, recorded motion is reconstructed using two DAC0808 one for X and one for Y.the speakers can reproduce sounds up to 20 Khz however we require a refresh rate of just 20 Hz ,however the amplifier between x/y output and speakers is still under construction.sorry for poor quality video.
