It's been a little while; it's time for a new (yet also old) formal release! The biggest change since v0.4 is the use of SMD resistors to sense the PCB flex, rather than gluing on strain gauges. This was recently informally stress-tested with 2 days of hands-on demos at Open Sauce 2023, and the resistors held up well with no noticeable calibration issues or drift during that period. While long-ter...
- move C10 slightly so that the top paste/stencil is identical to v0.2 (accidentally modified a tiny bit in v0.3). not a big deal, but I already have a v0.2 stencil so this avoids an unnecessary stencil change/reorder
STLs exported from v185 of the F360 model. This is still not recommended for general use (and these particular designs have not been tested at all yet), but this release is provided if you'd like to be on the bleeding edge and try building one. It may not work correctly. You have been warned.
In general, tolerances are very tight as the model was designed for a high-resolution 3d print, such as...
Changes:
- Top side test/solder points #11
- Remove "service loop" marks #10
- shorten flexure bridges (decrease slot length) so slots are less visible from above at an angle
- add holes for alignment to back plate
- change 3.3v regulator pinout to match AP2114-HA (In, Gnd, Out)
