Why the Viterbi?

Keebio's Viterbi is a double 5x7 otrholinear keyboard.

I personnaly don't like a keyboard smaller than TKL.
For a while, I've been using a Kinesis Freestyle2 (split but not ortholinear), then a Typematrix 2030 which appears to be really great and ortholinear (even the membrane switchs) for typing text. If you want to play games on it, don't even think about the Typematrix!

In my opinion, the Typematrix is a greate keyboard. The placement of the enter/backspace/del (and media) keys is a real pleasure. The biggest drawbacks to me are the lack of programmability, the lack of mechanical switches and the price (140€ ATM for a membrake keyboard).

After looking for DIY split ortholinear keyboards, the Let's Split v2 seemed quite interesting but lacking a few keys...
Keebio has a few others: Nyquist (60%), Levinson (40%), Viterbi (70%).
Naturally, I had to go with the biggest form factor: Viterbi.
I've ordered the PCB and FR4 (PCB) plates from keeb.io.

Assembly

The assembly is really easy even if the build instruction seem quite blurry if you're not adventurous.
Official build guide is for a Nyquist with a few keys more.
If you want to get the general assembly picture, u/ruhe has made a great Viterbi photo build log.
Assembly is as simple as:
- solder the diodes (the line marking on the diode package goes on the square hole),
- solder the TRRS jack and headers for the Arduino mini pro (you need 2 arduino mini pro),
- solder the 2 resistors on the master half (some people report that you can put them on any half),
- double check!
- solder the switchs through the switch plate on the side without any component soldered,
- finally solder the arduino.

Flashing

Get the qmk_firmware.
Then plug one half on the computer and flash it with:

$> make viterbi/rev1:default:avrdude

Do the same with the other half.
You can then plug the TRRS cable and try your new keyboard!

What difference between plate's material?

The PCB plates (FR4) have assembly holes on the inside of the plate whereas the steel plates have mounting holes on the exterior.
It's not important until you want to put a nice 3D printed frame to protect the keyboard's internal.
