Part 1 of this two part series is here.

In this video I continue to make my first LTspice circuit simulation. I am running this software under Wine on KDE Plasma running on Debian 12 bookworm.

I got some help with this simulation over on the EEVblog forum: Help with modeling multivibrators in LTspice.

There are some important errata concerning the above over on the EEVblog:

Part 2 of this two part series is here.

In this video I begin to use LTspice for the first time. I am running this software under Wine on KDE Plasma running on Debian 12 bookworm.

This is part one of two. In the second part I will show you the answers I got from my question over on the EEVblog forum.

My first LTspice circuit is the following circuit from project 9 from the Maxitronix Sensor Robot 20, which I have code named the 20in1.

The wires, power supply, resistors, capacitors, and transistors were easy to model, but the piezo buzzer and the CdS cell were both tricky.

In the end I found the Misc/xtal.asy component to use for the piezo buzzer. I got the various parameters for it from this datasheet (I just picked that component at random, I’m not sure what actual piezo buzzer is used in the Maxitronix kit).

The answer to my question on the EEVblog included hints about how to model the CdS cell.

Armed with my new knowledge I am now prepared to make part two of this interlude, so please stand by for that.

This video is part of the New Book Teardown feature of my video blog.

In this video I take a look at Beginner’s Guide to Reading Schematics, Fourth Edition by Stan Gibilisco published in 2018. The book has 209 pages.

Some things which came up during the video:

From the Wikipedia article on Bifilar coil: A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as different colored enameled wire bonded together. For three strands, the term trifilar coil is used.

From the Wikipedia article on Power dividers and directional couplers: Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of directional couplers is that they only couple power flowing in one direction. Power entering the output port is coupled to the isolated port but not to the coupled port. A directional coupler designed to split power equally between two ports is called a hybrid coupler.

From the Wikipedia article on Waveguide: A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which direct electromagnetic waves other than light like radio waves.

In this video I create some cables so I can attach my circuits to my roof aerial. I also announce the old book and new book for the upcoming teardowns which will be released in the next few days.

While doing this video I learned over on the EEVblog Electronics Community Forum that the specific RF cable connectors we are using in this project are Belling-Lee connectors.

There is going to be a break in Maxitronix 20in1 videos for a few days while I wait for my new Logitech BRIO webcam to arrive. Once that is here recording in the booth will resume.

In this video I mention the Silicon Chip magazine and Beginner’s Guide to Reading Schematics. Also the various new book teardowns I refer to are:

I also refer to MPLAB X IDE and MPLAB PICkit 4 In-Circuit Debugger.

The technology I mention in the beginning of the video is this:

The new monitor I refer to in the video is this UPERFECT 4K Monitor 15.6″ Portable Gaming Monitor UHD PC Screen USB C Monitor.

The cables I use in this project are these:
