Programmer Jig #13
Comments
In lieu of a proper jig, I've been using logic analyzer probes to program my watches for wearing, and wire-wrap wire running into a watch case for development. The logic probes are actually a pretty good solution, except that there's nowhere to clip them for power and ground. A few extra through-hole pads for the next revision will be welcome. |
It should be pretty easy to design a 3d printed fixture that takes pogo pins. I can do this when the final board is done. |
@sconklin The pad placement for the GoodWatch20 will be retained for the foreseeable future. Still up for designing that pogo-pin fixture? |
Hi @travisgoodspeed @sconklin, I used this one successfully in the past: https://github.com/ebuller/openfixture You just have to mark the pad placements in Handy documentation and assembly guide over here: http://tinylabs.io/openfixture/ There are more lightweight fixtures out there, but not many parametrized/automated ones and so well suited for KiCad :) |
Closing this issue in favor of a pocket watch design that can serve double-duty as a programmer. |
I am absolutely up for this but . . . I can't commit to any sort of
schedule.
TL:DR is that we were planning to move out of state, but then decided to
stay, but as a consequence almost all my prototyping and fabrication
capabilities are still unavailable.
With any luck, I'll be getting back to normal in a few weeks, but it could
be March before I'm at anything close to full speed.
The openfixture link looks intriguing.
Steve

No worries, Steve. Just reopen this issue when you get your lab back together, and your design files for a jig will of course still be accepted to the repo. |
While a watch development kit can be constructed with fly wires and an old GoodFET, it would be far classier to have a programmer jig that could sit beneath a GoodWatch board to program it or remain beneath it for integration testing or to act as a radio host.
Close this issue when we have such a jig, constructed to match the GoodWatch10's layout. Friction and stiff wires should be used in lieu of pogo plugs, if possible.
