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. [ ]
Special thanks to Mr. Ike Higgins for emailing me this article exploring a theoretical concept known as the Bubble Current Machine. Please note that this is presented purely as a conceptual thought experiment and design proposal. In practical physics, pushing air through a submerged nozzle against hydrostatic pressure requires external work equal to (or greater [ ]
Today I will explain to you how this simplest constant voltage and constant current battery charger circuit works. This circuit is very nice for charging battery safely without damaging it. It has two main jobs, one is limiting high current and second is stopping over voltage. Audio/Video Representation Main Parts Used In Circuit In this [ ]
In this post I am showing you one very nice and simple solar powered egg incubator circuit project. Many people ask me bro how to upgrade simple incubator with solar charger and battery backup so egg will not spoil when main power line is going off. In rural areas power cut is major problem for [ ]
Today I am showing you how to make very powerful pen style electric arc metal engraver circuit using IC 555 and MOSFET. Actually this idea is inspired by one of my blog reader, and my friend Mr. August. He made one crude engraver using 6V transformer and tractor charging coil, but he wanted a smooth [ ]
