I2C? Never mind.
11/22/2019 at 06:20 • 0 commentsAfter plunking around a bit, I've decided to abandon the I2C interface. Doing that with Analog I/O just takes up too much space for a FeatherWing, at least for these purposes. (If this was a full-sized Arduino Shield, that would be a different story!)
On the other hand, I'm increasingly uncertain about the MAX2268's Shutdown pin. I thought I had a handle on it, but turned out to be wrong. For now I've moved the connection from D12 to Ground; in a future update I'll either switch it back or abandon having the function altogether.
Once I've figured that part out, I'll check on the measurements for the headers and mounting holes.
On the upside, I think I've sufficiently de-spaghettified the layout that I'll no longer have to worry about that... at least for now. Of course, if I add any features, that may change.

New team members?
11/20/2019 at 23:22 • 0 commentsJust so I'm clear: There is some urgency about anyone willing to offer expertise, do breadboarding, etc., but only in terms of entering this project in the Take Flight with Feather contest. I plan to see what I can do on all that on my own -- I do want at least a couple of these in my hands -- but for financial reasons I won't be able to until after the contest is over.
And of course anyone providing any of that help would be invited to join the Team on this Project, whether it's before the contest deadline or after. (In case it helps, I'm not sure I could even make use of that gift certificate.)

Mostly minor updates, but more questions
11/19/2019 at 18:44 • 0 commentsA few things I got done this morning:
- Tightened up the space between components, mostly to save on copper (we might as well conserve our natural resources when we can, right?) and to open up space for potential additions (like a possibleI2C connection, as mentioned in the Questions).
- Added a couple of Open Questions. If I add any more, I'll probably divide them between those asking for technical expertise, and those that just ask for opinions from a user's standpoint.
- Made a specific recommendation for the mike and speaker connectors. (See the Parts list.)
- Minor proofreading, mostly for grammar and style.
One problem I had with the Parts list is that the reordering doesn't seem to be working. I can move things around just fine, but when I Publish it, the list reverts most if not all of my changes. This hasn't happened with the names or Comments on the Parts; only on the list order. What's up with that?

General Expansion & Update
11/18/2019 at 18:14 • 0 commentsI took a close look at some items today, and accordingly:
- Changed two of the three pin connections
- Rearranged some of the traces on the PCB
- Expanded the questions for visitors to answer
- Did some miscellaneous checking and cleaning up
Hopefully I'll be able to get a little feedback.
