Quick FYI for the bench-techs in the group.
A few months back, I became aware of this device, as well as the others
produced by the same fellow:

He's producing several types of low-cost, precision voltage / current /
frequency references. Prices

I'm not sure if it would make a difference but in your membership options to
the list you can choose the format of the messages and how you'd like to
receive them. I know my settings are plain text but I haven't played with the
others to know if they have an option like that.

There's a Sophie Wilson talking head exhibit at the Science Museum in
London where she says the prototype ARM chip worked well but when they went
to measure it power it used they discovered that the power pin was not
connected. The ARM CPU was running on current leaking from the chips it was

This reminds me of an incident of my own which is one of my favourite
examples of why learning about things at every level possible is
useful.

Just about anyone who's ever worked in ECL (non-saturating logic) is
aware of this and doesn't need to be reminded by anyone. The same for
anyone implementing logic using vacuum tubes.
In fact, the other aspect of digital logic is that it's a study of
transmission lines--and that's often voiced.

A somewhat related area is the many different ways in which a number
