This project flashes 18 LEDs at three different rates and you can use these to create a Christmas decoration of your choice. The circuit is kept simple (and cheap!) by using the 4060B IC which is a counter and oscillator (clock) in one package. The circuit requires a 9V supply, such as a PP3 battery. [...]

The Monitor Test program is a Windows application which comes in the help of electronics technicians for adjusting computer monitors and for general users for testing the quality of their monitors. It displays different patterns on the screen and it also allows to change the resolution from 640×480 to 1600×1200. These patterns are useful for [...]
This camera battery charger circuit will keep the battery for a train mounted camera charged and will shut the camera off after a few seconds when power is no longer applied to the track. This camera battery charger circuit is designed for DCC systems and the battery is essentially used as a capacitor as it [...]
600W power amplifier bipolar circuit The power amplifier delivers 600 watts into 8 ohms (bridge mono) or 300 watts into 4 ohms (stereo) – ideal for clubs, churches, auditoriums and more. Admission to the 600W bipolar amps is achieved via XLR or phone jack, and output is achieved through two Speakon-type connectors or terminals.the 600W [...]
This is a really small alarm that could easily fit inside a pocket. However, I also demanded reliable operation, simple construction and very low power consumption. I started with CMOS logic gates, but was soon forced to abandon the concept after a few unsuccessful (and far too complicated) takes. Then I suddenly realized that a [...]
