There's not that many blank PCBs, maybe 8 BS, 4 BS-DW and probably another 8 Solenoid Driver PCBs. If you're going to get them made preassembled, then it wouldn't make sense to use my blank PCBs, as the price will likely drop dramatically the more you get preassembled. However if you were set up to ...

PCB Assembly. PCBs are just the bare boards, no components, nothing soldered. Very important of course but not a lot of use on their own :) PCBA is the full board with components soldered on, sometimes tested etc.

PCBs are one thing, PCBA is another. Plenty of places do small-quantity PCBs (OSHPark, Seee(eeeee?)d Studio, PCBWay etc. Small-scale PCBA is a bit different, there are a few popping up now but they tend to cost rather a lot the smaller the batch is unfortunately.

Who is using a Beamspring daily? How are your (kind of longtime) experience?

Looks quite sleek without those dividers. Although they don't really interfere with typing they do clutter up the visuals somewhat—not necessarily a bad thing, but with them missing the keyboard now looks a decade more modern. Lovely job :D

My F107 doesn't have any spacers/gaskets, the plates are just bolted together through the case. It does mean you have to be a little careful with assembly to align the plates with the case, otherwise (as with the beamsprings) you can have keys rubbing on the case. I haven't converted mine yet, no ti...

For ARM USB stacks (along with rest of libraries etc.), check out libopencm3. It's LGPL, not BSD, but still fine for most purposes, even commercial.

Those Sparkfun solenoids might not be such a good idea. Unlike the IBM solenoids, they have a very long throw, so there'll most likely be a noticeable delay when they activate. The IBM solenoid clickers only seem to move about 1mm or so. Also, the IBM solenoids hammer themselves against their own mo...

xmega is a very different architecture than the plain old mega (as per DT's beloved Teensy). They're (partly) 16-bit and the registers are completely different. They're also 3.3V.

Nice job! Why was it that you couldn't bolt it into one of the tabs? Was the ribbon cable just bending too much?

You think they'd do something about keying that female header though (or using colour-coded wire) to stop connecting it up wrong though; I didn't see the red dot but if it's on the device itself it'd be pretty hard to trace it back through twisted wires?

That speaker thing is intriguing, I remember seeing it on photos of Kuato's board but I thought nothing of it and must have though it was part of the mechanical assembly of the case somehow. 18 ohms is a bit low for the solenoids (they are 30–35 ohms I think); the interesting thing is that that woul...

You know (at least with LUFA) relatively easily if your microcontroller has enumerated and is functioning over USB. If it isn't, you default to PS/2. The electrical interfacing if you want to share a connector and pins is somewhat interesting, but not impossible. You may be able to just hook everyth...

There is kind of charm to the slightly uneven pressure across the board causing pitch-variations in the pings.
