I bolted an old PC case fan to my microphone stand to act as an air extractor over my soldering station.

I’m in the process of attempting to reverse the power control signal on an AC adapter I purchased recently, this is the first investigation…
This video goes with my question over on the EEVBlog forum: Help with DC adapter.

Decadence
When I was a kid I had a clumsy analog multimeter, and I would have been awed to have something like this. Now you can buy them for $5, so I got a whole bunch of them…

IDC ribbon cables
ChatGPT tells me about Insulation-Displacement Connector cables, such as these.
RTL
The initialism “RTL” can stand for both “Register Transfer Level” and “Resistor-Transistor Logic” as explained by ChatGPT.
Critical Path != Critical Section
I always get the concepts “critical path” and “critical section” confused.
The “critical section” is the part in your algorithm which you must hold a lock for; whereas the “critical path” is an idea from hardware design which relates to the time taken for the longest combinatorial logic that needs to be processed during a clock cycle, thus limiting the frequency you can run your clock at.
Although the terminology “critical path” came from hardware, the same terminology is used in software. ChatGPT has a fairly good write-up on the two uses of the term “critical path”.
I learned a little more about this in Introduction to VHDL for FPGA and ASIC design.
