What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

I finally finished my Infinity Ergodox keyboard. I received my Carbon SA keycaps yesterday.
This has been an excellent keyboard! It has also been fun to learn to type on it. The layout of the keys is comfortable, and the mechanical switches themselves are a nice feel on this keyboard.
For keycaps I am using the GMK Carbon SA keycaps modifiers and the PBT Double-Shot keycaps (Slate/Lilac) from another drop for the alphas. As I just installed them, I am still figuring out how I like the two sets together (The grays are ever so slightly different.)
I took some time to figure out the default layout, then looked online to see what others were doing. I ended up with a main layer and three additional layers , and I am enjoying it, as I don't have to move my fingers off home row (Except when using linux/unix style vi arrow keys ¯\_(ツ)_/¯ I mapped my windows arrow keys to match this, since I use both OSes ). The first layer is the default function keys over the number keys, and I added the arrow keys to HJKL. On the second layer I made the numbers be a layer lock for all the different layers (I was experimenting on the 4th and 5th layer with different thumb clusters layouts.) The third layer is a COLEMAKs layout, and I plan one day to learn to type using that layout
Here is my current layout:
The switches are Cherry MX Browns, and I like the slight tactile'ness to them, but thought the springs were a little light (I am guessing 45g-48g). So I ordered 78g and 68g springs from Originative Co to replace some of the keys. I ended up replacing the entire home row with 78g springs, then replaced the keys above and below with 68g springs. The 2u thumb cluster keys were replaced with 78g springs. This has been a better feel (Less accidental presses when my finger slightly touches another key during a press.) I might in the future replace the 78g's with 68g's and replace the 68g's with 58g's.
I am working on a way to know when CapsLock, NumLock, and ScrollLock are "ON", so far my thoughts have been to add LED's along the thumb cluster edge (CTRL, ALT, and END/PGUP), or reprogram the LCD screen to show a status bar with the different icons. I would love to know what others are doing to know the status.
I am tenting my keyboard with the Kinesis tents (V3 Accessory for FreeStyle2) that I modified to let them lay flat on the keyboard. I am testing two methods of attaching them (Velcro and some thin plywood that I cut wedged and dovetailed, then superglued to each side.) both methods seem to work well so far, and I usually tent it to the 10 degree mark.
Here an image:
I still need to make a case for this, since I haul it back and forth to work in my backpack. I am currently using a folded up towel, and each half slides down into it a separate pouch. It is a little bulky, and I think a little woodworking would create a nice solution.
Well, that's all folks, thanks for reading :-)
MD sent me replacement PCBs but now I have to de-solder 80+ switches and transfer them to the new PCB. I asked MD to send me switches + PCBs and I will return the ones I got but that was a no go. Some day this year (hopefully) I will find time to de-solder the switches and try your idea out.
I am worried about water damage on it though. My hands tend to sweat a bit in warm temperatures.
In case this information helps, some of the LEDs work if I put positive side to the right and some (on the same hand) work if I put negative side to the right. Some don't work at all.
I thought some connection got reversed somewhere maybe that's why this happened but I don't know what to look for. I didn't know there were LED driver chips in there as well. If you can help me out, I will be very grateful.
