Up is OFF. That is, when the gate turns ON the mosfet turns ON too, and the DRAIN voltage goes to the negative rail. When the gate turns OFF the mosfet turns OFF too,…
Here I use the standard Joule Thief circuit, with a 2n2222a metal-can transistor and an inductor with 1:1 winding ratio from an old TV set, to illustrate the use of the AC coupling function…
Experiments by Roy, R.; Rao, M.L.; John Kanzius. The authors have shown that NaCl-H2O solutions of concentrations ranging from 1 to 30%, when exposed to a polarised radiofrequency beam at 13,56 MHz at room…
This is a simple AM radio receiver that use an integrated circuit chip called the MK484 as the main component. This simple radio will run on one AA battery using an earphone. I show…

Thanks to all who is helping! Today I’m thanking JC Worthless. But I want to think you all! He is doing his part in the way he can to kelp me help you fix…
just another test in search for practical use of oscillators; alternative lighting from DC source (IT lighting inverter) . in second part some info about new Magnetic M-G from Pakistan
Based somewhat on a Jeanna’s Light or Lidmotor’s similar circuits, this is a lot smaller inverter than the one from the other day. It fits around the base of the 120V 2W Lights of…
