The 555 Timer I.C. Datasheet Explained – Part 2

The specifics of what is talked about in the video.

This is the 2nd post and video describing the 555 Timer I.C. The first post was “The 555 Timer I.C. Datasheet Explained – Part 1“. I finished up all of the important information about the chip and external components in this video. The Desulfator

The 555 Timer I.C. Datasheet Explained – Part 1

LM555 Block Diagram

The heart of the Desulfator is based around a 555 timer. The 555 Timer I.C. is a very old and proven circuit and I can remember it being used in the 1970’s when I was an electronic technician. This the first of probably three posts talking about the 555 timer datasheet.

More Testing Work on the Homemade Box and Pan Brake

Gap between the hinged board at 90 degrees and the base board with no metal.

Another step forward with the brake project. I cannot say the light at the end of the tunnel is very bright yet, but I am pretty sure it is not a train. I am a whole lot more hopeful

Introduction to Bipolar Junction Transistors – Part II

A testing biasing circuit for a PNP Transistor

Tonight’s post is a continuation of the previous post “Introduction to Bipolar Junction Transistors“. In that post I talked in detail about the current flow in an NPN transistor, this post will start out with the same detail about a PNP transistor. Later I will extend

Bipolar Junction Transistors

It has always been my goal on this site to present information to help to understand every project I attempt. I am currently working on the Desulfator. Although I am primarily taking the design of someone else and building a printed circuit for it, both you and I need to know

Debugging the Homemade Box and Pan Brake.

The stiffening bar on the back f the hinged piece

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
