Design a PCB
Budget: €250 – €1,000 EUR
Design a PCB to interface to a bru-ray Optical Pickup Head (OPH) signals, using this (file attached) info as a guide and reverse engineering your way through!
The PCB should provide 3 programmable current sources for the 3 motion voice coils of the pickup head, 6 isolated outputs for photodiodes A, B, C, D - plus their sum (A+B+C+D) and diff ((A+C)-(B+D)) signals, as well as 1x analog input for driving the UV diode laser of the OPU
