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....

ZealPC has some gold ones that you can buy https://zealpc.net/collections/accessories/products/gold-plated-hot-swap-sockets-for-pcbs
You can also get them from Digikey in bulk, the led ones are cheaper then the golden ones so you can save a little there. https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/8134-HC-8P3/A114359-ND/1151726
Space: If you have a kitchen table, then you have space for soldering. Knowledge: As others have posted, there are very good videos online that can train you. It will work. Tools: This is the one thing that you probably don't yet have, and must physically acquire. The Sparkfun site has many appropriate tools for sale, though: https://www.sparkfun.com/. Other posters will probably have links to other good sites. You will need a soldering iron, solder, flux, and de-soldering wick and/or a solder-vac. Those tools don't take up much space when you pack them into a box in a closet, so space is not too much of a concern.
You can ask yourself if you want to own the tools at all. I think that if you are planning to solder even two different projects of this cost level, then it is worth owning the tools. One project? Maybe you could borrow the tools?
Have fun!
