Aerodox Flies on Wireless Wings
[Simon Merrett] didn’t know anything about keyboards when he started this project, but he didn’t let that stop him. [Simon] did what any of us would do — figure out what you like, learn enough to be dangerous, and then start fiddling around, taking all that inspiration and making a mashup of influences that suits your needs.
The Aerodox design became a cross between the ErgoDox‘s key layout and the logic and communication of the Redox Wireless, itself a reduced-size version of the ErgoDox. Interestingly, [Simon] chose the ErgoDox’s dimensions and spacing, and not those of the Redox. Like a lot of people out there, I found the ErgoDox to be too big for my hands, mostly in that the thumb cluster is too far away from the mainland. It’s nice to see that it suits some people, though.
[Simon] worked up a custom hot-swap footprint that makes the board reversible, much like the ErgoDox. Each half has an NRF51822 for a brain, and there’s a third one that acts as a receiver. This external NRF board is connected over UART to an Arduino Pro Micro, which acts as the USB HID and runs QMK. It’s an interesting journey for sure, so go dig into the logs.

If you’re of a certain vintage and have ever done any technical drawing, chances are good that you used a r0tring of some kind, be it pencil or pen. Well, r0tring makes more than writing implements. They also made electronic scribers — a small plotter that pens ISO lettering on technical drawings based on typed input. This was a huge time saver over doing it freehand or stenciling each letter. The CS-50 is designed to hold the top-of-the-line r0tring drawing pen, which turned out to be the most expensive part of this restoration aside from the time spent sniffing out issues.
[Atkelar] likes to open things up and give them a visual inspection before powering them on. We think this is good practice, even if the suspense kills you. But really, [Atkelar] did so much more than that. He started by replacing the likely late-80s-era coin cell even though it registered north of 3 V. Then he swapped out all the electrolytic caps and one tantalum, cleaned the rubber dome keyboard parts with a cheap electric toothbrush, (another great idea), and completely disassembled the x-y mechanism to clean and re-oil it.
