A simple Switch – flip flop

Given that the diode can be made to conduct, or not to conduct, simply by the choice of applied voltage polarity, then it must be possible to use any diode as a switch. So if you want to follow me, then just wire together the following circuit on a bit of breadboard, or something. Set […]

Making TV Pattern Generator with ZNA234E

Making TV Pattern Generator with ZNA234E This Circuit uses the ZNA234E IC which makes available all the waveforms necessary to produce the crosshatch, test patterns on a television screen. The composite video output can be injected directly into the video input of a receiver or used to drive a modulator for connection to the aerial […]

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 […]
