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....

Edit: The seller actually just confirmed that it is a Teensy. What I did with the dfu tools is then irrelevant. On a different computer (windows 10) the default configuration is working again but I still do not manage to load anything on the board.
Windows 8
I bought this Ergodox from Ebay (http://www.ebay.com/itm/ErgoDox-Ergonomic-Mechanical-Keyboard-Cherry-MX-Blue-Fully-Assembled-NOT-Kit/182395182981?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D40806%26meid%3De281706be3e34d0e93bec8cba4891f42%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D182401231837).
First I tried to flash it using Teensy. I downloaded from the massdrop configurator the default configuration. I loaded the .hex file to the Teensy loader, and activated "Auto" mode.
Second I downloaded the dfu tools (https://s3.amazonaws.com/configurator-assets/kii-dfu_win-0.2e.zip) kii-dfu and dfu-util (v0.8). Pressing "List Devices" and "Flash" in kii-dfu give:
Then I started the Zadig tool (http://zadig.akeo.ie/) (v2.2), options->List all devices and in the list I get 3 items I expected plus "Ergodox ergonomic keyboard", but there is no " Kiibohd DFU Bootloader " as indicated here (https://github.com/kiibohd/controller/wiki/Loading-DFU-Firmware#windows).
Since then the keyboard does not respond any more, except I see the 3 RGB LED turning on when I plug it in. I do not know what to try next.
