Archive of the former Yahoo!Groups mailing list: MOTM

I just finished my Blacet / Wiard Miniwave converted to the MOTM format and
fired it up. Wow! Everything worked right off the bad except one LED was
bad. That was an easy fix. :)

I have some observations:

1. I must say this is an impressive piece of hardware. Great job Grant and
John on a fine module. I have only one, but I can see that I will
absolutely have to have another.

2. Calibration of the input trimmers for "span" and "offset" is fairly
critical, but was very easy to dial in perfectly in short order with an
oscilloscope. I really do not possibly see how that calibration can be done
properly without a scope.

3. I have a WAV that I think would be great in the Miniwave. It is sine
waves harmonically added together like a Hammond so that you can get that
"organ sound" stacked oscillator sound from one device. Anyone interested
in including it in any EPROM they are working on? It seems different than
anything already in the "A" prom.

4. Bank and wave CV control requires a full 10 volts for full range. Since
an attenuator is included in the package, I would have scaled the Minwave so
that 5 volts of swing would have been plenty. The attenuator could be set
to 50% for 10 volt swings. This seems like an easy modification. The
actual resistor cannot be changed, because it is part of a network. But, if
a 100K resistor is tacked across RN5 from pin 3 to 4 and another 100K across
RN6 from pin 5 to 6, full sweeping would be possible from 5 volts swing
with the attenuator set to 10.

5. This conversion from the Blacet to MOTM format is the most difficult
project I have run into because so much advance thinking and re-engineering
is required to make the package neatly fit the Stooge panel. However, I
think a really good set of instructions will make this task MUCH easier. I
have photographed my entire process. And, I am about 1/2 done with the
written instructions. When complete, I will post this detailed set of
assembly / conversion instructions to my website.

6 The silkscreen layout of Dave's for the Stooge panel requires one switch
to have pin 1 at the top while the other must have pin 1 at the bottom. I
will have all that detail in the instructions.

Lastly, I will highly recommend this module to everyone. It is an exciting
toy. Many kudos to John and Grant.
