In practice, this seems to work only for people with sufficient
background knowledge. They take the 2-transistor latch/driver-type
SE apart, are surprised (polite words) and proceed to design
something that actually works right - that's what for instance Ken
Huntington did, and resulted in his Micropower SE.

Without the background knowledge, and usually working alone with
nothing but Webpages in front of them, people are often merely
confused by the 2-transistor latch/driver plus voltage trigger
thingy. At some point they either give up or think they understand
when they don't.

Imho more can be learned by building properly designed, described
and explained gadgets. I think it would be a good idea to extend
the BEAM magic to circuitry of that kind.

Best,

Steve
