1.2V simple ‘555 A-Like’ circuit
Low voltage, low current possible solution for those without 555 timers in the spares box. The basic circuit is much like a Joule Thief, similar toroids, windings and transistor can be used. The Collector…

Simple way of making sparks from an old television line output transformer. Main problem on these is that you are never quite sure of the pins to use for input output etc. Winding your…
This is a simple “Free Piston” Stirling Engine that I made in my kitchen. It is based on a design by Bladeattila here at Youtube.
This is my Muller testing unit upgraded and with a simple drive circuit. The drive circuit uses only one pair of coils and is similar to a Bedini SSG circuit. The device shown here…
This is my simple pulse motor running on a 10 farad super cap filled to 2 volts. In the video I stop the motor and show how the circuit goes into self- oscillation similar…
Voici une méthode simple et efficace pour savoir si une résistance ou un composant est inductif ou non. C’est aussi une méthode de mesure de la valeur d’une inductance de quelque µH à quelques…
This is a simple steam engine running on air blown through a drinking straw. The design is very old but is easy to build with basic tools and average skills. A link to the…
Hydroponics, simple without the fuzz of fish growing, using chemicals etc… 4 pvc tubes, connectors, a water buffer, 1 waterpump and some compost tea. Look how to make compost tea. I use some of…
Here is a very simple electric motor I built to try out a few things I have seen on Youtube. It is a combination of others ideas gathered into one device. Thanks to all…
This is my simple pulse circuit with a bifilar air core coil instead of the solid core coil that I showed in my last few videos. The advantage is that the strong magnet spins…
