First, let me compliment you on your insanium project.  I have done a 
bit with the speakjet but nowhere near your effort.

I doubt that your request will get much of a response which is an 
indication that this project is dead.  I think that it is a great 
concept but that the potential user community is too small for a 
project to emerge.  There just aren't enough experienced volunteers 
with time and energy.

John and I did a display board which is currently useful only to PSIM 
users since the CVS does not exist.  I have learned that early 
expressed interest really means "maybe and ask me again later when you 
have it" and later turns into "not right now I'm too busy / broke / 
whatever".

I think this project is too complex and too costly for the DIY 
community. Obviously the project could be simplified, but with some of 
the ideas that were proposed about 0 to +10V and +/-5V inputs with 
offsets, two banks of potentiometers, etc. it translates into well 
over 50 wires to a front panel and a BOM well over $400 in cost.  The 
only practical implementation for the DIY community would be to do 
multiple PCBs - one for the processor and another for front panel 
mounted jacks, switches, leds, and controls.  This represents a 
significant investment in both time and prototype costs.

There are also multiple formats so there will never be enough volume 
to justify the cost of develping the PCB and panel.  There are just 
too many formats for anyone to do a design with enough resulting 
volume to make it worthwhile.

This forum has really turned into a support group for the few PSIM 
owners that are active with their modules and general questions about 
using processors for voltage control.

Anyone care to disagree?

Dave
