Here's what I've been working on for a while. It still
needs a lot of adjustments. A surface-mount PCB-design
for the current schematic is 90% done - it fits in
less than 1/2 a euro-board. Don't expect the
through-hole version to be that small.
The LT1012 design got put on hold a bit - its only
advantage was that it can use larger resistors at the
inputs (though not large enough).
Please read the design notes on the schematic and
comment on what I've done so far.
Various stuff:
It runs on four 1.5V batteries.
It uses a LED for data transmission into a plastic
fiber. I've posted a schematic for the receiver
previously.
I've cut away everything non essential, so forget
about expandability...
