I tried to make the TravelDox earlier, but was not really happy with it, due to the size, thus beating the portable USP.
So, while AcidFire was on a rampage, I though of the ErgoTravel, an ErgoDox based smaller keyboard.
You can see below the keys I pulled off from the ErgoDox to use in the ErgoT.
The ErgoDox has 76 keys, ErgoT has 46 keys.
I wanted a keyboard that was small enough to carry however, kept the essence of the ErgoDox, the split design, the matrix layout, the variation in the column heights.
Hence was born the ErgoT. You can see below how each layer has an alternating hinge style plate, so they can lock and form a hinge at the top, which can be loosened and tightened to set the desired angle.
To solve the problem of having a connection cable between the two halves, I modded the second layer from the bottom to have a hollow hinge, which should allow a ribbon cable to join the two halves.
I switched out the one keys in the inner most columns at the bottom for a 2u keys to work as the primary thumb keys.
I also switched the 1.5u keys for 1u keys in the outermost columns to keep form factor small.
I got the layers cut today in 3mm acrylic. I will not bolt them together and add switches. I just realised I don't have a Teensy, so I will wait until I can get one. However the main idea behind this keyboard is the layout. The electronics are standard and should work.
I would rather start work on a PCB than wait for the Teensy at this state.
