Re: What parts have you successfully resin printed?

I printed only keyboard cases and some simple keycaps with an FFF printer.
But another deskthority user used SLA for keycaps and switches:

Re: Arthritis - Which layout and switches (need help)

I would go with a split contoured keyboard. Dactyl sounds ok. But you can save time (and probably also money) with e.g. Kinesis Advantage. You do not need to move fingers much with a contoured keyboard. But you can type with thumbs only (two finger typing) on a flat keybaord :-/ Definitely something...

Re: Ultrasonic Key Cap Cleaning - 2021 Edition

If you want to do it commercially for people who sent you a bag of keycaps and receive back a bag of cleaned keycaps then your approach is fine. But dehydrator does not make sense for people who clean their keyboards from time to time. The biggest amount of work is not cleaning or drying. Even when ...

Re: Ultrasonic Key Cap Cleaning - 2021 Edition

Ultrasonic cleaner is fine and useful but you do not need dehydrator. Keycaps can dry themselves on a piece of cloth or directly on the keyboard. I just dump them from the cleaner on a piece of cloth and start putting them directly onto the keyboard blowing on the underside of each cap to get any bi...

Re: (Concept) modulable keyfeel optical discrete switch

Wiki claims that the best of humans can hear up to 28 kHz. Dogs up to 45 kHz and cats up to 79 kHz. It is not a problem to make it about 30 kHz. Going higher, especially to the cat range would mean to cut corners a tiny bit on control precision since common counters are fed by 180 MHz source at most...

This is the part I have not very clear, why would I want to PWM the switches?

Re: (Concept) modulable keyfeel optical discrete switch

Have you calculated exactly how much power would be used by an HHKB sized board? Still not, but the stronger the permanent magnets and the less the wire gauge, the more power efficiency of the switch. That is rather strange way of understanding how electricity works. Although the current required t...

Re: Teardown - Omron B2H triple-magnet clicky Hall effect switches

I have a guess for the metal plate behind the slider magnet. It is there to linearize magnetic field change depending on press depth. The hall sensor output should be more linear with it.

I do not think Commander X16 makes sense though. MCUs are cheaper and better for a new stuff. Emulators are cheaper and better for the old Commodore stuff.

But the Commander X16 project is cute and funny. Not really useful though.

Since you do not have proper thumb clusters then +1 for a split space bar. Even if you use it in gaming sessions then you probably do not use full width of it with one hand.
