Btw I got a few PMs for questions of total costs and help with assembly. I'll just post it here too so know you what parts to source and cost expectations:
- 1 PCB $35
- 1 case $??
- 1 plate $18
- 1 teensy controller $20
- 87 diodes $2
- 87 switches ~$60
- 10 stabilizers (plate mounted cherry or costar) ~$10
- 1 USB cable $??
- keycaps $??
That's roughly
$150 before shipping and other fees. Of course the number of switches and diodes will vary depending on the layout you choose, but not by much. The only layout that adds significant amount of switches is the 7bit layout, which is a little over 100 switches.
edit: I just realized tjcaustin also posted a list of things needed. It's correct for the most part but $300 is grossly overestimated unless that includes buying a brand new $150 filco just for the case.
