Circuit can be used for multiple Camera – Switch to monitor
Circuit can be used for multiple cameras with one monitor. The circuit can be operated manually or automatically. When operated automatically the switch will be connected to the output of 555 astable multivibrator that will send a continous square wave in the 4017 counter. When counter is running, the 5 transistor will switch one by […]

The four channel PMT controller board
Controller Circuit Board The four channel PMT controller board is a PIC microcontroller based device that communicates with a PC by USB as an HID device and with a PIC-based “hand unit” via PIC-to-PIC RS-232 protocol. These two external inputs (USB and RS-232) send strings to the PMT controller that: * Sets the four high […]
