After finishing my handwire I began using my keyboard at work. I started loving it so much that I decided I wanted it to become a real thing, not only a handwired prototype, hence the Redox rev.1.
I used KiCad and this awesome guide to get things started. Since I didn't know if I could trust my skills and footprints I designed and manufactured a test PCB.
Needless to say it all worked out perfectly. I then extended what I already built and created the rev.1 PCB.
Then it was time for the hard part of the project: case design. My first idea went really bad: i wanted to replicate the handwired design but I couldn't get the angles just right and it looked horrible.
Also you may notice that my 3D printer had some problems in the final layers of the print.
I then decided to change the design of the case and adopt curved lines all over the place. This was the design I adopted in the final version.
At this point I realized I needed a way to recycle my failed prints...
Final assembly.
Instructions can be found here. Case files are available on thingiverse.
Materials:
- 70x: Cherry MX compatible switches
- 2x: Redox PCBs
- 2x: Redox cases
- 70x: 1N4148 diodes
- 2x: PJ-320A 4 poles 3.5mm TRRS connectors
- 2x: 4.7kOhm resistors
- 2x: Through hole momentary switch
- 2x: Arduino pro micro
- 1x: TRRS cable
- 1x: USB micro cable
- 70x: Cherry MX compatible keycaps
- 10x (8x for 1u Layout): 1.25u keycaps

This time around I added LED backlight because I felt so.
At this point I should probably mention that I like purple...
After publishing some pictures of the PCB on instagram I was contacted by Falbatech and now the Redox is a product available on his store.
