Thanks to my mate @edk from IRC I learned of the compose key. I configured my KDE Plasma desktop to use Right Alt as my compose key in System Settings -> Input Devices -> Keyboard -> Advanced. Then I updated the firmware and deployed a .XCompose file that I generated, and now I have a symbol keyboard on my Debian Linux workstation!

I want to learn more about sigrok and OpenTechLab seems like a good place to start…
gusmanb’s 24 Channel 100MHz Logic Analyser
In Build – gusmanb’s 24 Channel 100MHz Logic Analyser from Happy Little Diodes I learned about this Logic Analyzer project. I would like to try building one of these for myself one day too.
100MHz Logic Analyser
Today I watched Build – gusmanb’s 24 Channel 100MHz Logic Analyser by Happy Little Diodes which is about how to make your own 100MHz Logic Analyser for cheap.

Silly Job Title: Component Wrangler
In this video I add improved debouncing logic to the inaugural Silicon Chip and Jaycar Mini Project: JMP001.
Shout out and thank you to Tim Blythman for developing this project.
You can see Tim’s original code and my updates which improve the debouncing implementation.
In the video I mention that we use the pgmspace.h header from Arduino.

In this video I make a power breakout box. This is for use in testing my new multimeter, but it will be good to have for other uses in future too.

Interlude #8: Making My Maker Faire ‘Here There Be Makers’ Badge | In The Lab With Jay Jay

In this video I fix up and reassemble my Here There Be Makers badge which I received from Maker Shed in California.
This electrified badge was made by lectrify.it and PCBWay.
Previously I had installed a single 3mm LED in the top of this thing, but in this video I remove that (so I can use the hole to hang it) and install two 3mm LEDs on the front instead, which is my best guess as to what I was supposed to do with this thing, which didn’t come with instructions.
There is some information about their Maker Faire event on in San Fransisco later this year over here: https://make.co/welcome/
And also, yes, I should have combed my hair before making this video. :P
