Today I learned about the Baker clamp. It’s a circuit to help speed up transistor switching time. I learned about it over on Diode-transistor logic § Speed improvement where it said it was developed by Richard H. Baker who described it in his 1956 technical report.
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 watched this great video: Faulty Peak DCA55 Component Tester – I was shocked! | Can I Fix It? They had an excellent result from Peak Electronic Design Limited when they sought support for the DCA55.
One day, when I am rich, I plan to get the full set of measurement devices manufactured by Peak Electronics.
Today I heard about the Jumperless V5 over on Hackaday: Jumperless Breadboard V5 Readies For Launch. Looking forward to hearing more about that when it launches in a few days…
I plan to binge watch all of these videos: @OpenTechLab. I hope I can find the time!
This is great: Is That A Coaster? No, It’s An LED Matrix!
I want to learn more about sigrok and OpenTechLab seems like a good place to start…
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:
