Temperature Monitor with IC LM741 or LM301 Using a thermistor in the position shown makes a heat activated sensor. A change in temperature will alter the output of the opamp and energize the relay and light the LED. Swapping the position of the thermistor and 47k resistor makes a cold or frost alarm. Temperature Monitor [...]
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 [...]
An Uninterruptible Power Supply (UPS) is a device that sits between a power supply and a device to prevent undesired features of the power source (outages, sags, surges, bad harmonics, etc.) from the supply from adversely affecting the performance of the device. The UPS may be split into 4 main circuits: Input Power Factor Correction, [...]
