You're missing the "title" text from this comic [1]: "Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shit."

[doublepost=1534387470,1534386321][/doublepost]I've been idly thinking that the Pyra really needs a VGA connector. And a 25-pin RS-232 port could prove useful. And a kitchen sink would also be a nice-to-have, so that we can brag it's got one. And a connector for a docking station. So many interesting things to think about for an imaginary future version!

You can find many examples of USB RS232 adaptors, and 15-pin VGA adaptors too. I'm not aware of any USB kitchen sinks, but it's fair to say I've not actually checked. And I've never come across 15-pin RS232 either; it's always come on a DE-9 or a DB-25 where I am.

In other news I can see (an interesting message in the Pyra newsgroup) that @hns has been doing some amazing work fixing an intermittent issue with the modem powering down.

Most credit goes to ED, but there are plenty of other relatively unsung heroes...

Indeed. But they don't work reliably (I've tried both FTDI and Prolific chipsets), especially with slower devices with which reliable flow control is essential.

Yup, that was a typo. I've corrected it now. Thanks. (I've been using a full-sized keyboard for a few days, and coming back to the compact keyboard on my laptop, my "2"-finger reaches the "1" key!)

Strictly speaking this overvoltage design flaw is a consistent issue that was intermittently observered, rather than an intermittent issue. What a _huge_ relief that it can be worked around in software! (A board revision and another year's wait would have been A Very Horrible Thing.)

One can't help feeling, though, that this mistake should have been discovered when the prototypes were being tested last summer. Perhaps there is a lesson to be learned here and the test procedures can be made more thorough/complete.

To be fair, practically 100% of hardware/software issues can be predictably recreated once the underlying issue(s) are identified. The hardest part is usually identifying those root causes.

And yes, it is a huge relief :)

Regarding any "should have": hindsight is a great thing in terms of identifying what _could_ have been proactively done, but what matters most is that the issue has now been identified and fixed.
