This simple yet highly sophisticated, smart LED street light circuit automatically switches ON a street lamp from low brightness to high brightness whenever it detects a moving object underneath it. This action is initiated only during nighttime, while during daytime the street lamp remains completely shut off. What this Circuit will do This advanced automatic […]

Modified Sine Wave Inverter Circuits using IC 555, 4017, 4049, 4093 and BJTs
When an inverter with square wave AC output is modified to generate a crude sinewave AC output, it is called a modified sine wave inverter. The following article presents interesting modified sine wave inverter designs with exhaustive descriptions regarding its construction procedure, circuit diagram, waveform output and detailed parts lists. The designs are intended for […]
3 Simple Battery Desulfator Circuits Explored
In this article we investigate 3 simple yet powerful battery desulfator circuits, which can be used to effectively remove and prevent desulfation in lead acid batteries. The first method uses PWM pulses from a 555 PWM circuit using existing battery power itself, the second concept involves high voltage spikes, while the third design discusses desulfation […]
Recover Energy from Induction Cooktop
The idea of acquiring free energy from induction cookwares using an external bifilar coil was suggested by one of the keen enthusiasts and a regular visitor of this blog. I have explained more regarding the details of this interesting radiant energy device, as explained by the author himself. WARNING: THIS CONCEPT ATTEMPTS TO VIOLATE THE […]
How to Recharge Dead Batteries
In this post I have explained how to recharge and use bad, defective discarded batteries using an innovative battery charging process invented by John Bedini. Lead acid batteries can sometimes be a problem to get rid of. They can also be high priced to upgrade. In case discarded in the wrong way, they have a […]
Solid State Relay (SSR) Circuit using Two MOSFETs
SSR or Solid state relays are high power electrical switches that work without involving mechanical contacts, instead they use just a couple of solid state semiconductors like MOSFETs for switching an electrical load, smoothly, and with high efficiency. SSRs can be used for operating high power loads, through a small input trigger voltage with negligible […]
