In my last post, Starting Towards A Custom Built Keyboard, I left off with my pining over the idea of an ErgoDox; a split keyboard, with full programmability of the key mappings.
A new co-worker and some Obsessive Compulsive Syndrome
After an extended weekend with it, he was determined to learn to touch-type so he could try out my Das Keyboard with its Cherry blue switches.
It was at this point his (officially diagnosed) Obsessive Compulsive Syndrome kicked in.
He dove in and learned to touch-type, and soon he was ready to try out the unlabeled keys of the Das Keyboard which had been “taunting him” from my desk at work.
After just a few days with the Code, and then the Das Keyboard, he fell (back) in love with mechanical keyboards.
Of course, since he was learning to appreciate touch-typing, instead of just hunting-and-pecking, I introduced him to Steve Losh’s Modern Space Cadet post.
As the old IBM Model M’s don’t support USB, he found the TMK Firmware project by Hasu, and assembled some converters which would allow him to use his older keyboards with his current computers.
If you are curious on his journey down the rabbit hole, he has been starting to document it on his blog at www.clintgeek.com.
The Ultimate Hacking Keyboard
Meanwhile, I was still on the hunt for a split ergonomic programmable keyboard.
My thought was it would net me a programmable keyboard, as well as a split keyboard, without having to assemble it myself, and if it would turn out I wasn’t a fan, I could likely sell it to someone who missed the pre-order.
To top it off, it outlined that it was going to have magnets that would hold it together in a non-split mode.
Being uncertain of if I would even like a split keyboard, I saw a reduced risk in the purchase, in that if I tried the split mode and didn’t like it, I could always fall back to non-split mode for the keyboard, yet still have something that was programmable.
And of course, hardware being as it is, it has (understandably) been delayed a number of times as the project has progressed, but should hopefully be arriving this August (2017) as of last update.
Sierra and Karabiner
While awaiting the Ultimate Hacking Keyboard, and watching my co-worker dive deeper in to customizing his keyboards, I was sitting in a holding pattern before upgrading to OSX Sierra as it meant incompatibility with Karabiner due to changes in OSX.
Karabiner Elements was eventually announced as the replacement for Seil and Karabiner, but didn’t give the full extensibility of Karabiner, and I wasn’t going to lose my “Hyper key” from my keyboard without a battle.
Because of this, my co-worker was busy trying to sell me on the idea of building converters for my keyboards myself, but kept un-selling himself on the idea, as “a USB-to-USB protocol wasn’t quite supported”.
The “sales” cycle continued in this manner until he finally mentioned:
“Now, if your keyboards supported the PS/2 protocol, that would be very easy.”
Getting ready to make the dive
With those magic words, he convinced me to build a set of converters for my keyboards, as building the converters would mean:
- I can specify the key-mappings I want at the firmware level in the converter, and not have to worry about operating system compatibility of key remapping software;
- it also gives the added bonus of being able to bring my keyboard to someone else’s desk to pair, plug it in, and have my keyboard work as I am used to;
- remove the converter so that someone can use my computer with the standard key-mappings they are used to;
- or possibly even using someone else’s keyboard and using my converter with it to get my key mappings.
With a previous order of a nicer soldering iron over the $3 one from Harbor Freight I had, and an order from Amazon for:
- A three pack of micro-USB to USB adapters
- A five pack of USB Micro to USB braided cables and
- A three pack of ATmega32U4 boards.
I was ready to start on building some converters for my keyboards.
