Octavio,

I too would like info on your work.

Actually, let me ask you a question.  I play drums and often need to use a
metronome to set and maintain correct tempo.  This works but has drawbacks
in live situations where it is nice to let the tempo move around a bit but
still be at or near the reference tempo.  When using a metronome, once you
'drift' off beat you are 'out of sync' with the metronome and its difficult
to tell if you are still playing at the same rate with a quick glance.
There is a product on the market that uses a piezo on the snare drum and
displays the real time tempo (bmp: in beats per minute) on three 7 segment
LEDs (range: 40-300 bpm).  I bought one and it was terrible!  He used
discrete logic (11 IC's) and the tracking was bad and the resolution varied
according to the range.  Basically it was worthless!  I could really use
something like this and I knew even I could do better.  I've gotten started
on my prototype and so far have a metronome running along at a fixed 120bpm.
Using an '84 with a ICL7218D multiplex display driver (would eventually like
to roll this function into the '84), blah blah blah....

Anyway my question to you is, might you be interested (or have the time
even) to help?  I've been way to busy with work and other things to be able
to put time into this learning project but I could really use the working
product now.  I'm sure someone with your experience could whip something
simple like this out in no time.  Whereas, it will (already has) take me
much longer.  I do have some other 'features' to add to it if possible but
mostly just need to get this part of it going.  I don't know if you would be
interested in something like this or not.  If so, I'd take anything from
free suggestions to (depending on cost) compensating you for more detailed
help.  I will supply any info you would need (parameters, circuit ideas,
function, interface).

I guess I just need to know if you are even interested or able to do
anything like this? If so, what might you need to charge for your time?

Please let me know (or at least send the info on your semi-related projects
- anything that could help will be extremely appreciated!).

Thanks for your time...
