I have finished this project almost 2 years ago, but I didn't want to release it before LittleSixteen V4. I have built a few keyboards and I have been using at least one of them almost daily for all that time, so I think I can say this has been tested quite thoroughly.
Building one of these is not a trivial task, but it can give you a lot of satisfaction once all the little bits and pieces come together, in particular if you have never messed with mechanical keyboards before, like me.
So, have fun!
Released files
Note that the released gerber files are password-protected. The original reason behind my projects was to allow anyone to make their own retrocomputing accessories cheaply. Instead of this, what I achieved was actually fuelling greedy people grabbing my work, making boards for a couple of bucks and the selling them at outrageous prices ($15 for a badly-soldered OpenC64Cart that costs $2 to make is just ridiculous).
I still believe in free software and open hardware, and that is why my projects will remain as such. I am no longer providing ready-to-use gerber files, but you can still generate them from the KiCad project or ask me for the password, if you think you don't fit the above statement.
If all you want is to get boards made, I would really appreciate if you did it as explained in the Support section in order to get them cheaply while supporting the project.
Note that you are NOT allowed to use these boards commercially, but I won't care if you sell them AT COST. Let me repeat that: AT COST.
