Laser pointer light show using cd-rom drive's opto-electronic tracking module and a cheap "laser" pointer,
with Microchip's PIC16F73 microcontroller.
demo (youtube) video:
* still on-going pa rin ang pag-develop ng code, still looking for a better
beat detection algoritm* "hinaluan" ko muna ng "pattern" sa code
schematic (simplified):
* +/- 1V ang kelangan nung dalawang coils (represented by 2 motors in the schem.) ng module
* around 5ohms ang dc resistance ng coils)
actual circuit:
* pinalitan ko yung original lens ng module ng lens nung "laser" pointer (bigger diameter).
main components used:
*cheap "laser" pointer (super bright red LED) and CD-ROM drives's opto-electronic tracking module
