I’ve modified the ergo mini board from the Atreus thread
with the necessary keys for most programmers (or those who
want a mini board without the need to Fn for numbers and
punctuation) and it’s only a fraction of an inch larger than
the original. This will be compatible with Easy AVR
Keymapper.
Since I’ve gone through all the work of
design and prototyping I figured I’d share with the
community if there’s interest in a group buy of the boards
and/or cases. I’ve got the first batch of prototype boards
ordered already, waiting on arrival for testing, then I can
move forward with a larger batch. If you’re interested in
helping with the prototype testing I can send you a board
for $25 ($30 total if you want the SMT parts too, I can
pre-solder them if requested) including shipping when they
come in.
For a small run <50 boards, the cost is:
$25
per board
$10 for the SMT components (soldering is
+$10)
$35 for the case in acrylic (4 layers: top 1/8”,
plate 1/4”, spacer 1/8”, bottom 1/8”, includes nuts, screws,
4 rubber feet)
$6 shipping
For a medium run 50-250
boards the cost drops to
$10 per board
$6 for the
SMT (soldering is +$10)
$30 for the case
$6
shipping
