This is a pictorial diagram of a Joule Thief (JT). It is meant to give a simple visual guide to those who wish to assemble their own JT. I’m also adding sort of a Joule Thief FAQ to explain in simple terms what a JT is. JT – WHAT IS IT? A conventional Joule Thief

This is about a guy who recently posted a video based on “Free Energy” or overunity on Youtube. This guy seems very innovative, he builds a lot of stuff. He calls himself my video is on utube (with no spaces). I asked him for permission to put some of the messages here but he didn’t

I’ve got several power supplies that I use on my bench or wherever, and I really don’t know why I bought this new one. But It’s getting very close to Xmas and I wanted a present from Santa. I guess I’ll have to explain further to justify my frivolity. Hewlett Packard, AKA Agilent I have

A few years ago, 2007, I believe, I blogged a few Joule Thief circuits on which I experimented. I used the 2N7000 low power MOSFET and the TN0702 (I’ll get to that one in a later blog). Choosing a MOSFET The 2N7000 is a small signal, low power MOSFET in the standard TO-92 plastic package

Back in 2000 and 2001, Californians faced an electricity shortage crisis caused by market manipulations by companies the likes of Enron that stole tens of billions of dollars from Californians. The electric companies implemented rolling scheduled blackouts to prevent unexpected outages. During that time, many people were afraid of being caught in a dark place

I checked out the AGC microphone on Techlib website, and I like the circuit. I have some LF353 opamps I got from Radio Snack a long time ago (I used to look in the blister packs and see both LF353s and TL072s), and I could use it in place of the TL072. One thing he

I received a a lot of comments on my Supercharged Joule Thief circuit, which gives an efficiency of up to twice that of a conventional JT (more about this in my blog where I switch between JTs and measure the light output). The SJT requires a few additional components, nothing out of the ordinary. Essentially,

My Joule Thief Plus or JT+ circuit uses an idea similar to that used in my Supercharged Joule Thief (SJT). My motivation for designing this circuit was the situation faced by the experimenter when s/he wants to drive a high power LED using a 1.5V supply. The conventional JT runs into a major brick wall

This is my replacement blog for watsonseblog.blogspot.com. After it was “removed because of spam” (I don’t spam) I lost four years and over 700 blogs. I will attempt to recreate some of my most important blogs, judged by the amount of comments I received. More to come as time permits. BTW, if you have a
