A silly project – just for the fun of it. – A grabber toy.

Dr. Suess grabbing device.

Sometimes projects are highly planned out. Sometimes not. Sometimes you know exactly how you are going to do something because you have lots of experience doing it. Sometimes you try something new and experiment. This was one of those projects were I had very little idea how I was going

How a GFCI operates and why it requires no ground.

Magnetic field around a wire with the conventional current flowing into the page.

Way back, a long time ago, I started introducing the idea of inductance in a post called “Through the Looking Glass – Duality – The Inductor“. To start talking about inductance it is necessary to talk about electromagnetism and that is

Examples of Problems with Grounding Electrical Systems

Faking out the Ground Plug.

Tonight’s post is a continuation of the last post “Grounding and Neutral in Power Wiring” and I am going to show a couple of examples of problems with grounding in power and even instrumentation and audio systems. Some of these problems are in my opinion still not resolved and

In the last Post “Test 2 of The Box and Pan Brake – Making Progress” I said I was making progress. I am beginning to feel right now I am not although I think I am. Most blogs and D.I.Y. articles do not post

The Second Baby-Step with the Box and Pan Brake.

The clamp board with the steel edge

Remember, the reason babies are made close to the ground is so when they fall they don’t have very far to fall. Well, I am no baby, but I can avoid wasting a lot of time, money, and effort by moving forward in small steps and testing

Progress on the Sheet Metal Box and Pan Brake.

The Brake Base and Hinged Board

I have mortised the hinges using the fixture I described in “Making a Hinge Mortising Fixture” and have assembled the boards as I described in “The Hinged Plate for a Sheet Metal Bending Brake”. Like always there is good news and there is bad news. I think there

Making a hinge mortising fixture.

Router Guide Bushing

In computer programming there is a term called “stuck in an endless loop”. Usually programs do the same thing over and over using different numbers and if you somehow forget to tell the program how to stop executing the loop it just continuously keeps doing the loop forever. Sometimes us humans

Finishing up the Enclosure for the Power Supply

The final enclosure with everything mounted

Way back there I did all the sheet metal bending to form an enclosure box for my power supply. (Post “Brains not tools… Making an Enclosure for Electronics“). I did not like the power supply board open because it has 120 V on it in some areas and

Removing old, glued down, vinyl flooring.

The room after we were done with it.

This site is not about typical do-it-yourself home remodeling but I just put a large amount of effort in doing just that and I think I have something to add so I will add it. The room was in bad shape and our Granddaughter will be

Graphical Construction: Drawing a circle tangent to other circles

An actual problem solved. The build of wire making a coil

Tonight’s post is a graphical construction that does not have a built-in function in CAD. Drawing circles tangent to other circles was an actual problem I had to “go back to the books” to solve a problem. The picture to the left is
