pic18f1220 microcontroller circuit controlled 3-axis laser show effects partially founded on a simple apparatus. PIC18F1220 RB2, RB3, depending on RA6 pin PWM MOSFETs are driven by motors belonging to construction have lots of pictures and details also shared PCBs and the C source code through
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.

PIC16F877 ISA Ethernet Web Server Project
The PIC16F877 microcontroller, prepared with activated an old ISA ethernet (3com eherl Link) Used guess PIC internet connection with an application I’m not sure 🙂 circuit aim could not understand the pic programming dealing with people who can solve resource asebbely asm PCBs (eagle) control program and so on. most likely reason for not publishing files to the work of people who are interested will work.
