Back in '89, Daniel Durbin posted here that he built the A/D circuit
contained in DIGITIZE.ARC. More recently, Alan Jones released DGTZ-VOI.ZIP
which is the Digitized Voice Programmer's Toolkit for the PC containing
a newer schematic for the circuit and several support programs for it,
including an editor for the data files.
Now, I may be very late in discovering this, but Las Cruces BBS's
aren't usually filled with the latest releases. We're sort of a backwater
town deep in the wild west (yeah, right).
Has anyone besides Mr. Durbin managed to build this thing and get it to
work? I, and two other friends, have each built one of these 'things' and
none of us have come up with one that works. Two of us managed to get some
output from the thing, but it consisted mostly of pops coming from the
capasitors firing off. The third, well, nothing ever came out of it.
We also discovered that if we plugged in, say, a walkman, turned up the
volume all the way, and listened REAL carefully, we could hear what we were
putting into the circuit. But the noise from the circuit's capasitors (I'm
guessing that's what it is, I'm a BCS major -- the other two are the EE's)
drowned out and distorted the output. In short, it didn't compare to the
relativly CLEAR quality of the sample .VOI files that came with the package.
Does anyone have any suggestions or fixes for this?
