how's the battery life?
Sorry for the late reply; this thing lasted a bit longer than I expected. I managed to get two samples of battery life using a hard-bound bluetooth dongle and the fully charged 4400mAh battery. Both lasted right around 4.5 weeks of continuous connection.

Re: Geac 8340

The diodes were simple enough, but how did you open the switches without damaging anything? I can't even seperate the individual switches that formed the right column. I left the 'waffle' assembly together and just pulled the sliders. There's two little clips on the bottom that hold in each one. I ...

Have you checked in the casing to see if the broken pieces are floating around? If you can find them I'd be glad to make a CAD model and print a few.

Re: Best font + color scheme to maximize keyboard readability?

Some of the commonly available 'high contrast' sets are just black text on bright yellow with large letters. It would really depend on the person what's most readable though; max contrast isn't always the best option. Some forms of sight/reading impairments benefit from different color schemes. A co...

Re: Has anyone successfully cleaned Monterey "Clicky" Blues (Alps Mount)?

Sorry for the necro! Just want to confirm - is it possible to open up Monterey/SMK switches while they're in a keyboard? (= not desoldered) Not really. Even if you could get the clips apart there wouldn't be a good way to align stuff when reassembling. The contacts would stay with the bottom housin...

I tore down the switches and ran them through an ultrasonic cleaner before I soldered everything in place. Threw on a quick QMK map and it works great! Switches are surprisingly smooth given their reputation. I got lucky with my board in that very few of the stems were cracked. I just put those on t...

It's yours to do with as you please but man do I hope you keep the surface finish as it is. Only way it could get that patina is years of neglect. Definitely one of a kind!

Re: Model M SSK Case

Awesome 3D models! Hopefully there will be one day when you can get reasonable surface quality with 3D printing for projects like this. You can pretty easily get mirror finish on an FDM printer if you are willing to do a lot of sanding/vapor polishing. Resin prints are even easier. Getting the orig...

Well the sanity check passed! The PCB won't be perfect but there's enough wiggle room that alignment can be made to look good. I finished up the PCB and ordered a set of 5 (the minimum); they should be here in about a week. Here's the KiCad project and the gerbers that I sent out: https://github.com...

Re: Omnikey Plate repaint

For bare metal it's a good idea but not strictly necessary. There's plenty of paints that don't require it such as the engine enamel mentioned. It generally won't be as durable as good prep+etching primer+color but for this application it doesn't make a huge difference. Biggest thing to watch out fo...

Re: Omnikey Plate repaint

I'd do primer on the whole thing since it can affect how the color layers look. The color coat would only be needed on the front of the build plate which helps. If you don't care too much about the finish (matte vs gloss vs satin) you could just do a few thin coats of black primer and call it good. ...

I scanned and counted pixels on the case, switch grid, and PCB and everything seems to be standard 19.05mm/u. The right F row was spaced a little funky on the PCB at only ~0.94u.

Re: Omnikey Plate repaint

You'll definitely need to remove the rust before you paint it but sandblasting and all that isn't necessary. I would: Remove the switches Get the bulk of the rust off with a wire brush or 220 grit sandpaper Soak the plate in Evapo-rust and rinse Get it pretty smooth with some 220-800 grit sandpaper ...
