Grant,
Prior to the last week, no one with a suitable level of experience had
stepped forward to volunteer their time. Someone had kindly offered to
learn PCB layout to complete this effort, but this is not a beginner's
project. It really needs a medium level of hardware design expertise to
complete. My personal concern is that without a proper handoff the project
could get botched and leave an expensive and bad taste in everyone's mouth,
or it will require so much handholding that it would have been easier to do
it ourselves anyway.
While I have the ability, I don't have the personal time to complete this
project myself. I will get offline with a few folks to see what can be done
for a handoff of the schematics.
