I think I've settled on how to mount the Schism plate. I've added nubs around the perimeter of the plate with a notch on either side, and then you hook O-rings into those notches. That lets me tweak material and thickness of the gasket by getting different O-rings.

I want THICKER PHONES with FEWER SENSORS and REPLACEABLE BATTERIES and MORE LOCAL STORAGE and I'm not kidding!

I'm getting somewhat used to the way of doing things, switching between workbenches as appropriate (e.g. designing features in PartDesign, making arrays in Draft and doing boolean operations in Part.

I think it could be nice to have some of these features duplicated in other workbenches (e.g. PartDesign could do with having Draft's array tools). I'm sure there's some reason they're not, though.

Started designing the plate for the Schism keyboard. It's probably not necessary but I'm planning to gasket mount this, and generally do stuff to make the keyboard sound nice!

Updates on my Älgen guitar design: getting some actual wood, experiments in dying 3D prints, and designing some hopefully correctly complicated jigs:

If I've checked the "in stock" filter, why show me items like this, Farnell?

I think it's ready! I changed the connector over to an edge mounted one (which may or may not be very resilient to stress). Also took the chance to move the mounting hole close to the USB port, to hopefully strengthen that corner of the PCB.

It's not quite back to the drawing board - I'm pretty sure I can do my original plan which was to have the connector straddling the edge of the board. That way the connector orientation *does* flip with the board, so the pins do get swapped!

Good thing I checked the connector - it doesn't work out quite how I thought in my head! I thought flipping one PCB over and putting the header on the bottom instead of the top would connect pin 1 to pin 2 and vice versa.

But this paper mockup shows that pin 1 is gonna connect to pin 1, because both the PCB and the connector have been flipped so they cancel out.

Aaand I think that's the layout done! I need to review it (particularly how the connector between the two halves works) but I think that's pretty good!

Mostly done with the keyboard PCB - it's still a bit messy around the microcontroller, but I can live with that.

Oh, just realised I need to remove the ground fill under the antenna!

Getting there with the keyboard routing, but it's getting pretty messy. I think I'll need to redraw most of the tracks to tidy it up and rearrange stuff.

Show thread

It's starting to be less of a mess... or at least, a more compressed mess. Power stuff is mostly done, just got to connect everything to the microcontroller module and the keyboard half connector.

I'm gradually getting there with my split keyboard layout. I can tell that getting everything to the connector is going to be tricky! Tonight I'm dealing with the battery/power stuff in the top left.

Big news from the open hardware camera development front: watch the AXIOM PCBs run through our first industrial manufacturing run: apertus.org/axiom-team-talk-16

This is roughly what I'm thinking for (half of) the layout. It's a little weird-looking but I quite like it.

I think I can manage to make it so that you flip the left side PCB over to make the right half. If I can get my head around it, that is.
