Electronics is a hobby. I Blame Rev George Dobbs. His book, "How to Build a Transistor Radio," found its way into my hands when I was about 8. I'm now a radio amateur myself. And I teach radio and cyber to Air Cadets. My skills have gone from "take it apart, put it back together again and with a bit of luck it'll be fixed" to "I have designed and etched a PCB at home, hand-soldered the surface-mount microprocessor, AND it works."

But I am hampered by my workbench and lack of kit. I have an old CRT Tektronix scope that I acquired years ago from a radio rally. The timebase circuit is on its way out, so it only uses about 2/3 of the width of the screen. My bench power supply is a 13.8V linear CB power supply. My signal generator is a match-boxed size Vellman project which can do sine, square, and sawtooth. Oh, and I have a multimeter.

I'm just about to be starting a new career in cyber - hardware & physical penetration testing. I'll need to take network gear and IoT things to pieces, find serial ports, download firmware. I really don't think my workbech gear will be up to THAT challenge.

So I've included a picture of a project on my bench. This an an arial rotator that I modified by adding a USB interface. You can see the new relay board attched to the rotator in the front of the picture. In the background is my ailing scope. It takes up a big chunk of my bench too.

I've also included a pic of anothr work-in-progress. This is a test rig for checking CAN bus. I have a CAN device at one end and an arduino at the other. My scope doesn't do CAN decoding, so I have to attach the laptop to see what's happening.
