Machining porn in awesome. For a way to mount the teensy check this link. On the second page there is a second version where the mount holes are on the sides instead of the ends so that the break out board puts the teensy port at the edge instead of inside the board. This was done for people using it as an external converter for terminal boards.
I love the simplistic feel and the look of the raw metal. By the looks of things I am guessing aluminum? What grade if I may ask.
Sending you a PM regarding machining questions.
You should have a look at my project. Check the M-64 link in my signature.
I ended up doing the diy home version of the board that was shown in that thread. Just like I posted in that thread about making on out of perf board. I originally directly wired to the teensy so I had to desolder it and remove the old solder to put it on headers pins to solder it to perf board though.
It has a removable usb cable but you have to remove 6 screws to get to it.
Yes it is made of aluminum I thought i posted that, however i don't know what grade it is as it was just scrap I got for free and I tend to not question free metals unless we are talking tool steels.
the keyboard only cost me $50 usd total and that was just the original keyboard and the teensy. It also weighs 4.064 lb as a completed keyboard so it sure isn't the lightest keyboard around lol.
