Firecracker Igniter circuit [Remote Controlled with Timer]
In this post I will show how to construct a few fireworks ignition circuits which can safely ignite them via IR remote and timer. We have proposed three firecracker igniter […]
Higher Variable Output Voltage from IC 7812
You may have often wondered whether it was feasible to get higher voltages than 12 V from a 7812 IC? In this short post I have explained how to configure […]
Simple Tone Control Circuits
Tone control circuits are basically filter circuits which are used to filter audio frequency signals so that only the desired range of frequencies are allowed to pass to the amplifier […]
LED Star Circuit
This circuit can be used like a tree ornament, however the LED star circuit explained here has a variation; it’s completely electronic and it provides the impression of an exploding […]
