Here’s a standard for ATX Power supply connectors dan ATX power supply pinouts. Standard power supplies turn the incoming 110V or 220V AC (Alternating Current) into various DC (Direct Current) voltages suitable for powering the computer’s components. Power supplies are quoted as having a certain power output specified in Watts, a standard power supply would [...]
The original CK217 was an improvement on the CK200 FM Transmitter. This new FM Transmitter can transmit over 900 feet in the open depending on aerial used. The tank oscillator coil is built into the circuit board, and has been tinkered with to give the best distance and stability for it’s size. The battery supply [...]
The circuit below illustrates two pairs of LEDs that operate out of phase so as one pair slowly illuminate, the other pair will fade. Circuit description: This circuit is used to slowly illuminate and fade a pair of red LEDs (light emitting diodes). The fading LEDs could be installed as ‘eyes’ in a small pumpkin [...]
Switch-mode driven 1.5V bulb, Portable unit – 3V battery supply This device was designed on request; to control the light intensity of four filament lamps (i.e. a ring illuminator) powered by two AA or AAA batteries, for close-up pictures with a digital camera. Obviously it can be used in other ways, at anyone’s will.IC1 generates [...]
