hobbyist. Send me your favorite projects and your thoughts at email@example.com and I will publish them here.|
Let's have some fun sharng our enjoyment of this wonderful hobby!
|Don't Keep Bad Parts!|
you have paid good money for some parts but they seem to be of
questionable quality, just throw them out! You will be glad you did.
|200: Oldies But Goodies|
section is devoted to some of my early projects and the interesting
ways things were done "back then." Today these things are considered
pretty simplistic, but "back then" it was cutting edge stuff!
So, join me on a nostalgic journey to the early days of digital
|Product Design: How We Did It in the Old Days|
there were ʺolder daysʺ than this when we wrote machine language code
by hand on coding sheets, but by 1992 we had assembler software and
EEPROM burners that connected directly to
the PC. Major improvement! Hereʹs how product development went in those days. Click HERE
|Foucault Tester with Digital Readout|
you were an Amateur Telescope Maker (ATM) back in 1977 you know that
polishing and figuring the mirror was a major challenge. I was an
electrical engineering student back then and wanted to simplify
the process of figuring a mirror. A major help would be to have a
digital readout on your knife edge tester, so I designed this digital
micrometer. The design was published in Sky and Telescope magazine and later I was asked to make one for the Michelson-Morley Interferometer at the Palomar Observatory. Sky and Telescope Article
|The On/OFF Switch|
when the ON/OFF switch actually turned things ON or OFF? The ON/OFF
switch used to physically supply power or remove power from a machine.
the idea of "warm up" has been replaced with "boot up." Here's an
interesting bit of history about the way things used to be done. For this interesting article click
