This is another build. A laser set of three modules (power supply, driver module and galvo + lasers module) from China – put into enclosure. Added audio preamp for audio XY laser deflection control from computer – and some additional midi options (switching on\/ off one or more of the three RGB laser modules).<\/p>\n

On the top left: schematic swith stereo audio op-amp preamps for XY deflection galvo control
\nTop middle: midi input via optocoupler to arduino (Sparkfun) promini serial input pin D0
\nBottom middle: audio input layout for prototype board with optional audio sense on A0 and A1 inputs to blank the lasers when no signal
\nRight: arduino (Sparkfun) promini with pins D9, D10, D11 as on\/off switches via small mosfet transistors (not drawn…)<\/p>\n

Basic layout of modules and finished version in action – with audio preamp and midi control (via arduino pro mini)<\/p>\n\n\t\t
