RaspPi/Keyboard Project called Kiiboard, Still Pronounced ‘keyboard’

[b10nik] wrote in to tell us about a pretty sweet project that he just finished up. It’s a mechanical keyboard with an integrated Raspberry Pi 2 Model B inside.

[b10nik] purchased a new Filco Ninja Majestouch-2 keyboard just for this project. Although it may make some people cringe, the keyboard was immediately taken apart in order to find an open cavity for the Raspberry Pi. Luckily there was space available towards the left rear of the keyboard case.

RaspPi2 Keyboard insideIf you are familiar with the Raspberry Pi 2 Model B, you know that all of the connections are not on the same side of the board. The USB, audio, HDMI and Ethernet jacks were removed from the PCB. The Ethernet port is not needed since this hack uses WiFi, but those those other ports were extended and terminated in a custom 3D printed I/O panel . The stock keyboard case had to be cut to fit the new panel which results in a very clean finished look.

There’s one more trick up this keyboard’s sleeve, it can be used with the internal Raspberry Pi or be used as a standard keyboard. This is done by way of a FSUSB30MUX USB switch IC that completely disconnects the Raspberry Pi from the keyboard’s USB output.

For another RaspPi/Keyboard solution, check out this concept from a few years ago using a Cherry G80-3000 mechanical keyboard.


Delving Into the Design and Manufacture of a Keyboard

A while back [Dave] decided he wanted to build his own keyboard. [Dave] has no experience in design, or dealing with manufacturing companies, or even sourcing materials – he just wanted to see if he could do it.

That’s the beauty of the DIY world – most of the time, you can do it, you just don’t know it yet. The keyboard is made out of laser cut steel and acrylic sheets. The switches and key caps are Cherry MX Browns, supplied by GONSKeyboards Works. A Teensy 2.0 lies at the heart of the keyboard acting as an HID device, and the whole thing assembled looks pretty slick – but it wasn’t easy getting to that point.

One man’s adventures in custom keyboard development


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.
