I have been one who has built simple electronic circuits since my
childhood. It eventually influenced my higher education and
career choice. I've decided to share some of my designs in
that others can find some use in them. I am
these without any warranty or liability. It is the
responsibility of the builder to validate their work and ensure the
suitability of the circuit for their particular application.
to simply put things, use these designs at your own risk.
although you are free to use these designs, I kindly ask that you give
credit if you reprint or redistribute them. You are welcome
link to this page in doing so.
Model railroading can be a circuit-demanding
aspect which commonly requires electonics are switch machine
controllers. This is a circuit for that purpose.
Radiant heat is nice, except if it freezes up on
you. This circuit was designed for a friend to keep one of
hot water heating zones from freezing up when he used the woodstove.
Trunk System Scanner Advance
An older, now obsoleted circuit that I originally
help monitor an EDACS trunked radio system prior to the introduction of
EDACS capable scanners.
