Today I found Kevin Hubbard here:
He seems to know a fair bit about PCB design and FPGAs, which are things I am becoming interested in too.

New electrical wiring
My new 10-way powerboard arrived today and I wired it into the booth along with a PowerShield Defender 1200 UPS battery which I had spare.
Then I had two spare powerboards so I installed one of them (with an RCD Safety Switch) behind the bench. You can see it in the photo below. The thing you can see plugged in on the top is my Watt Meter, it reports on current draw and power usage.
I am pretty happy with today’s handiwork.
Sigrok and Logic Analyzers
I found this old series of videos from OpenTechLab which starts here: [001] Sigrok and Logic Analyzers.
There is more about sigrok over here:
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.

Electronics projects
I have organized the various electronics projects which will be coming up on @InTheLabWithJayJay.
Euler’s identity
I was talking to my friends about Euler’s identity and I was reminded of this one: The most beautiful equation in math, explained visually [Euler’s Formula].
In that context one of my friends brought Tau Day to my attention.
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.
Jan Axelson on USB (and Serial)
This week I discovered Jan Axelson. She’s a tech writer and her website is here: http://janaxelson.com/.
I have ordered four of her books:

In this video I use and mention my Jackcat Electric Scissors.
Also I managed to get my air-quality meter to work by squeezing it together with a clamp. It’s not pretty, but it works!
That red clamp you can see bottom left is holding the screen together and causing it to work…
