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.

You will need a soldering iron, preferably with temperature control, solder, a fine soldering tip, a solder sucker, a sponge, decent eye sight and a well lit flat place to work.
Watch some videos on YouTube of soldering technique. Read some articles on adafruit. Watch a few videos of people building keyboards on YouTube. Wodan is pretty good, and shows the basic process. If it looks like fun, then go for it.
Just keep in mind a soldering iron is NOT a brush ;)
