Octodon has become folding again

Hello, Habr.
Under the cut is a small but important update for those who are interested in the process of developing a fast and accurate Octodon compact keyboard.
Background: from the very beginning , from the last series .

In the fall, we settled on the option of releasing a separate device that connects to Android and iOS devices via Bluetooth, which can be attached to a smartphone using a magnetic mount, or used as an independent input device with tablets, desktops or smart-TV.

In the course of optimizing the ergonomics of the device, we made two significant changes:
1) Octodon began to fold in half and fit into almost any pocket. Its dimensions are 128x70x10mm.
( 3D model in folded form )
2) In the unfolded state, it has become much more comfortable in the hands due to an increase in its thickness when unfolding.

As a result of the use of the new transformation, the most convenient case of the device in the history of octodonstruction was obtained. A device 1 cm thick gains the appearance of a good joystick, which is critical for the convenience of ten-finger printing:

In addition, within the framework of this concept, the communication issues between the moving parts of the device were quite simply resolved.

We are currently working to simplify the case of the device so that the accuracy of conventional FDM printers is enough for its manufacture. Now, this is mainly prevented by the teeth of the gears synchronizing the opening of the wings. Ideally, the mechanics of Octodon can be assembled, having access to the technology of laser cutting of thin metal and FDM-3D printing.

The latest project information is available in our social networks. networks. Before the start of our crowdfunding campaign, we finally redesigned our site and launched the Russian version. There you can find additional information, FAQ, as well as additional graphic and video materials of the new prototype.
The new Octodon prototype has recently been discussed at geektimes .
