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.

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.
I found this old series of videos from OpenTechLab which starts here: [001] Sigrok and Logic Analyzers.
There is more about sigrok over here:
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.

Apparently GPT-5 will ship this year: BREAKING!! OpenAI **JUST** Announced GPT-5 [100X BIGGER].
I have organized the various electronics projects which will be coming up on @InTheLabWithJayJay.
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.

In this video I take a look at how to use all of the features of my new Fluke 17B+ Digital Multimeter.
This is the inaugural demo video. We now do an ‘unboxing’ and a ‘demo’ separately. In the demo videos we try to take a close look at each feature of a product. Whereas with the unboxing we just make a record of the unboxing experience and take a cursory look at a few features.
If you’re interested in the Fluke 17B+ then in addition to watching this demonstration video you might also like to see the unboxing: Unboxing #14: Unboxing of Fluke 17B+ Multimeter | Learning Electronics In The Lab With Jay Jay.
The slides for this video are here: https://www.jj5.net/fluke-17b-plus/
In the video we cover:
We were lead astray by the slide for the current test which indicates the wrong terminal for the current measurement! I got these slides from Fluke in the 15B/17B/18B | Quick reference guide on the Manuals+resources tab on their documentation for the Fluke 17B+ Digital Multimeter. So it is pretty disappointing that the official Fluke documentation led me astray like that! But we figured it out in the end so all is well that ends well.
Errata: at around the 24 minute mark I try to introduce a load across my 9 V AC input voltage but I don’t correctly wire it in. So when I think I’m testing with a load attached there is in fact no load attached.

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.
