A Homemade Box and Pan Brake – A better way

Sometimes… sometimes… you just gotta admit it. There is a better way and it ain’t yours. Actually that is what makes the net a great thing. There is always something to learn if you remain open to learn it and isn’t that the true goal: To become better and better. The only thing I wish

Stiffening up the Homemade Box and Pan Brake

The brace to stiffen the box and pan brake.

After doing a lot of work in previous tests I determined the brake could get the job done on small pieces of metal but just could not get it done on longer pieces because the hinged board was bowing when I applied the force necessary

Field Effect Transistor Theory – Part 3

Depletion Mode IGFET symbols

In part 2 I finished up the description of the JFET. Tonight I will describe the operation of an Insulated Gate Field Effect Transistor (IGFET). Most often an IGFET is called a MOSFET because of the materials used in it, Metal Oxide Silicon FET. For those of you that have

Field Effect Transistor Theory – Part 2

JFET symbols

In Part 1 we introduced a conceptual diagram of the construction of a JFET and talked about what happens if the gate voltages is changed in comparison to the source while the drain to source voltage is kept at a low value. Today we are going to start out talking about what

Theory Vs. Reality: First Comes the Assumpton Then It All Goes to Hell

This is a post where I could think of a lot of very funny names and titles, but when it came down to the actually writing one I chose the term I most often use in professional life. “First comes the Assumption Then It all Goes to Hell”. Very often the calculations and number crunching

Field Effect Transistor Theory – Part 1

JFET symbols

As we continue to work through the Desulfator circuit we only have one device left that we have yet to talk about and that is the MOSFET. A MOSFET is a type of Field Effect Transistor (FET). Tonight we are going to point the ship toward understanding it, but to understand the

Drawing the Schematic for the Desulfator in Kicad.

The Desulfator Schematic in KiCad

HAPPY NEW YEAR! Usually this time of year I think about what I accomplished in the last year and also where I want to go in the next one. I have been so busy this season that I really have not given it as much thought as usual. However,
