I've seen pictures of these, but I don't think I've used them more than once or twice. I wasn't crazy about them, but they sure do seem like they would make manufacture easier. How does their reliability compare to other mechanisms? > Before I found out about EOMA68 I was intending to make a raspi handheld > using this keypad layout https://mozzwald.com/public/images/misc/keypad.png > > Are there any preferred keypad layouts? That looks nice apart from the Esc key location. But I'm not sure where I would move the Esc key to within that layout: I'd have to experiment with it in my hands. Anyhow, users could re-map keys to suit their tastes, so that kind of detail may be moot :) _______________________________________________ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
