3-axis laser effects work
Originally I’m very lazy man so I’ve chosen programmed microcontroller PIC18F1220 PIC implements 3 channels PWM generator. PWM signal toggles MOSFET transistor 2N7000. Mirror actuator is connected as load to MOSFET. As mirror actuator I used 5V 200mA CPU cooling fan. It’s easy to mount mirror on its flat side. Device accepts 5V and 12V fan with maximum current 200mA . Voltage is selected by jumper. Green laser pointer is rated at 3V so I’ve made LM317 based voltage regulator with adjustable output.

160W IGBT Amplifier Circuit
Anfi circuit output stage GT20D201 (p-channel IGBT) and GT20D101 (n-channel IGBT) used quite a quality amp circuit printed circuit board design also pretty stylish circuit 8 ohm speakers with 88W 4 ohm speakers with 146w RMS real power can give noise (THD Total Harmonic distortion) level is very low 0.002% (1kHz) input Impedance 47.7
Quiescent current setting is done with P2 1k trim pot amp input signal is idle before entering the current drawn by the speaker to be between 200 to 100 …. P2 trim pot should be set. Circuit of the power supply circuit for resource discovery 2x30v 2x43v after rectification diode bridge transformer may 350w ac dc high voltage 86v In total there is going to be careful is that value-hander.
