This is the inaugural Mini Project! I introduced the Mini Projects recently. They are developed and published by Silicon Chip magazine, and sponsored by Jaycar Electronics (which is an Austrlaian electronics store, similar to Radio Shack in the USA, hopefully it doesn’t end up suffering the same fate.)

In this project, codenamed JMP001, we develop a USB keyboard which can send interesting and unusual symbols (which aren’t usually available on a keyboard) to a Windows computer using the alt-codes that it supports in a typical codepage.

For this first Mini Project I felt it was important to actually buy my components from Jaycar which I did for roughly eighty Australian dollary doos. Approximately US$50. The parts I ordered were these:

Belatedly I did also search for rubber feet.

There was quite a lot that went into the production of this video, and we accumulated a lot of links. Those are here:

In the end this first project was relatively successful, and we did get it to work fairly well on one of my Windows computers. As for the rest you can find out for youself in the video!

This is a note for Future John about how to report a recent coredump (with debugging symbols) on Debian:

DEBUGINFOD_URLS="https://debuginfod.debian.net" coredumpctl gdb

Then bt is a magical gdb command to run to give you the call stack of the thread which… failed?

In this video I do the tenth Maxitronix 20in1 Electronic Project Lab project: Speech Conductor.

In this project we learn a little about transistors, amplifiers, and astable multivibrators.

Note: while I was making this video I took a detour into making a cable, which didn’t work out. You can see the video about that over here: Extra Content #13: Failing to Attach Banana Plugs to Microphone Cables | In The Lab With Jay Jay.

In this video I try to attach some banana plugs to my microphone cables, but I do not succeed.

I tried to find some examples of how to do this properly on YouTube, but I didn’t find much: how to assemble banana plugs

I did find a video of a guy who essentially just explained all the problems I ran into: Banana Plugs & Binding Posts

And this one over here confiremed: How to fit a Banana Plug

In this video I take apart a broken kettle then put it back together, then magically it is fixed!

In this video I use my Yum Cha Mini Magnetic Precision Screwdriver Set for the first time. It takes me a little while to figure out how to clip the tips in. I needed the triangle bit for this job.

Protoboard

I have been on the lookout for some good protoboard for a while now, and today I found this: ElectroCookie Solderable Breadboard PCB Board for Electronics Projects Compatible for DIY Arduino Soldering Projects, Gold-Plated (9 Pack + 3 Mini, Multicolor Pack).

It is cheap and well laid out, which is a combination of properties I have had some trouble finding. For instance if you search for ‘protoboard’ over on AliExpress you don’t get any good results.

Anyway. I got myself two twelve packs. Average cost of AU$2.25 per board.

p.s. I went back and got these as well:

This ElectroCookie stuff is good value!

In this video I announce a few things:

  1. The definition of a “new book” is now anything published during or since the year 2000 (it used to be anything that was published within the last ten years)
  2. The various features of the show now come with numbers per segment/feature (this is Channel News #4 for example)
  3. There will be a new main show feature called Maths Homework which will be starting soon (I just need to get a new camera so I can record this new feature)
