[time-nuts] Updated Shera controller

[EWKehren at aol.com]

I assume that some one will donate their time end effort like I am  
presently doing on the Dual Mixer I have spend in excess of $1000 on the project  
and untold hours and do not expect any payback. I thought that is what 
time-nuts  is all about.

Full  circle back to the software, the number of units sold, the cost per 
hour  
and time to complete project would determine the software cost.  Would not 
surprise me if the software would be the biggest  expense till you break 
the 1000 
unit mark unless the cost per hour  was very low. As a hardware guy at 
heart it 
is hard for me to assign a  cost/value to software ;-)

One more comment $ 40 would cover  every thing including PC board, May go 
up 
to 50 depending what D/A you  use.  Bert

Uhm, isn't this exactly  where you want to use  the
still-smelling-like-brand-new-car PICTIC II with  a good DAC  and
a microcontroller ?
