One man’s adventures in custom keyboard development

BlueCube-flat

As a software developer, [suka] spends a lot of time every day in front of a keyboard. He had been trying out different keyboard layouts far less common than even the moderetly obscure Dvorak layout, and after some time decided a custom ergonomic keyboard was what he wanted. His progress of designing his own custom ergonomic keyboard is a fascinating read, made even cooler by the fact these are real, professional-quality keyboards with mechanical switches and custom enclosures.

After starting off with a few USB numpads, [suka] dove in to the world of Cherry switches by crafting his own wing-style keyboard. [suka] works for one of the larger manufacturers of laser-sintering machines, so he was able to create the enclosures for his keybaord – as well as the key caps – fairly easily. The technology behind laser sintering allowed [suka] to create some strange bowl and trough-shaped keyboards before settling on his daily driver, seen above.

The Blue Cube, as [suka] calls it, includes an integrated stand, an integrated IBM trackpoint mouse, and is powered by a Teensy microcontroller. [suka]‘s keyboards might not be heafty enough for melee combat like the venerable IBM Model M, but it’s exactly what [suka] wants, and that’s just fine by us.

Kitchen scale key transplant

[Markus] is quite happy with his kitchen scale. It’s one of the tools he uses most frequently when cooking. But recently the button has begun to give him problems. He figures the years of spilling a little bit of this and that has mucked up the contacts. His solution was to bypass the button using a Cherry MX switch.

Really any replacement should do since the switch merely completes an electrical connection. But there’s a subset of hackers who swear by the Cherry MX switches that come in some keyboards. [Markus] had just such a keyboard on hand, which he was already using for parts, so he pulled out the switch and cut a hole in the scale’s case where he could mount it. After temporarily super gluing the switch in place he completed the task by filling the gap on the outside with hot glue, then running another bead of it along the inside. The addition of the ‘T’ key finishes the hack. The plastic key is easy to clean and will help shed flour, oil, or anything else he might spill during his culinary adventures.

This hack was fast and easy and may have convinced [Markus] to roll his own controller board for the device. We’ll keep a lookout for a follow-up post detailing those alterations.
