Dual Slope A/D Converter
A few years ago I got this idea into my head that I wanted
a temperature gauge. This was before I knew about microcontrollers
other than as a part of my "To Learn" list. I decided
I wanted to build one. I could have gone to Radio Shack and bought
one for far less effort, but this was to be a learning experience.
I decided to build it all with discrete logic. This was my first
mistake. I remember in a few electronics classed we went over
dual slope analog to digital converters, always in a block diagram
sense, and I told myself that I could do that. Well I did,
and you can see the results. I don't know if I'll ever be
able to accurately reproduce the schematic, though once I find it,
I post my (flawed) original.
