some of them may even end up as products :-( I am sure
I've told you
how
I once showed a so-called designer who wanted to use a microcontrolelr
module + input interface modules + ... as part of a control system that
his problem could be solved using few lengths of wire and otherwise
unused contacts on his relays and swithces. Hmmm...

I used to work for Volvo, developing the maps for ECUs for engine control.
One of my colleagues wanted a simple indicator showing the injection time,
i.e. for how many milliseconds each engine revolution the injectors were
open, to see how his mapping was working out in practice when test driving.
He asked for help from the electronics lab, who came up with a proposal for
a digital display, all-singing, all-dancing precision device which would
cost $$$$$, come in a nice 19" case and take months to design. He went off
and made his own indicator instead, using a 555, a moving-coil meter and
some passive components. Quite a number of his devices were built for
everybody else in the department, IIRC.
