Today I am going to share a very useful and clever circuit diagram sent to me by Mr. August Peterson. This circuit is a non-contact HT spark tester and timing light tool. It is specially designed for modern cars where checking for a spark is very difficult and dangerous for the car electronics. Why Mr. […]

Make this DIY Spot Welding Machine using MOT and IC 555
Building a spot welding machine at home, it does not really need those complex SMPS circuits or costly stuff, nope. Instead a much simpler way is there, which people use, and it works quite well. We can use a microwave oven transformer, that MOT, and then add a small timing circuit with it, so now […]
DIY 100 Watt MOSFET Amplifier Circuit with PCB
MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easily beat the performance of other counterparts based on power transistors or linear ICs. Why use MOSFETs in Amplifiers Amplifiers based on mosfets are not always easy to design or make. Moreover after assembling a prototype, testing to perfection […]
Make this DIY Contact MIC Circuit
Contact mics can be used to sense unusual sounds when attached to various surfaces.It also Produce sound when voltage is applied to it.With the help of a basic Pre-amp circuit it can also be used to Electrify an Acoustic Guitar, where amplification is a must. Written and Submitted by: Ajay Dusa Piezoelectric Disc as the […]
DIY Taser Gun Circuit – Stun Gun Circuit
A Taser circuit also known as Stun Gun circuit is one non-lethal electric shock producing unit used to paralyze a person for a time being without causing any severe damage or injury. It is a very useful device, especially to immobilize an attacker. Using and making of stun gun is restricted in most of the […]
