NOTES FOR THE VOICE DIGITIZER CIRCUIT


1. You can only print this schematic on an EPSON-compatible
printer.
2. I used batteries to power this circuit. It requires 12V,
which means 8 AA batteries. You could also use a 12V power
supply, but it has to be **QUIET**. I think the batteries
are easier. Since the circuit will only be on for a short
time, they should last just about forever.
3. Wire this circuit carefully and don't screw up any of
the connections. Take your time.
4. Wiring layout isn't critical. You should see my sloppy
circuit board.
5. All parts are available at MidState Electronics on
Monterey St. You can save a little by buying the Mic at
Radio Shack, though.
6. Cost for the electronic components should run about $15,
but the cabinet and other hardware bring the price up. For
resistors and capacitors, go to the counter and just buy
what you need. Avoid the packaged goods.
7. USE SOCKETS FOR THE ICs!
8. Observe polarities on the electrolytic capacitors.

Serial Port Notes:

If you have a DB-25 connector on your serial port, the pins
for this circuit are:

CTS ---------- Pin 5
Signal Ground -- Pin 7


If your serial port has a DB-9 connector, pins are:

CTS --------- Pin 8
Signal Ground -- Pin 5

FINAL NOTE:

When you first try this circuit, don't be surprised if it doesn't work.
The adjustment of the 50K pot is critical. For me, it worked almost
exactly in the center of the pot's travel. Experiment!

GOOD LUCK!

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
