A project log for Digitabulum: The last motion-capture glove

Digitabulum is an open motion-capture glove that was intended to be a full-featured, hacker-friendly user-input and sensor platform.

Devoted some time to adding another project to hack-a-day (WebRemote). It might end up being an early target for demonstrating android integration, since it is already a functional application.

Yesterday, I added Mathew to the project. Mathew and I have been friends and coworkers for years. He has written his own 3D game engine for android (from the shader code on upward to materials and physics), and has been an inestimatable help with the conceptual side of this project.

In lieu of a finished repo re-org, today's update is exported PCB artwork. These are the 4 signal layers....

There are also 2 power planes (6-layer PCB), but those are not interesting enough to post.

I let the auto-router make a variety of choices about the IMU boards. When the first prototype arrives in the coming week, I'll select the best PCB design and panelize it for a 4-layer process to save cost. The metacarpals PCB can probably also be cut down to 4-layers with some re-org. After the phenomenal success with the CPLD, I will be able to cut lots of complexity from the cable-attachment areas of both large PCBs.

To come will be the upload of all of the datasheets to go along with the BOM I posted yesterday at the project's site. I will have a longer digression about the PCB there.
