Simple solar inverter + tiny circuit 1.5V driven mains bulb
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…
Electric OU: Supplement: MOSFETS… How do THEY work???
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,…
Joule Thief: Supplement: More on AC/DC Coupling, Scoposcopy, 2n2222a JT
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…
Simple AM radio using MK484 IC
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…
Don Smith Device Project Part 19 C: New Driver with L1 and L2 Tank Circuits Complete
Completed the Tank circuit for both L1 and L2, the values are not quite correct for L2, .03uf is what i need, but i accidentally used .3uf 😀 So it should get even sweeter…
Salt water burns: the experiments and results
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…
