Shiny New Keyglove Firmware on Github

Shiny New Keyglove Firmware on Github

The development between now and my last post has been pretty significant. I published a new Kickstarter project update a few days ago, but I don’t want to fragment the news updates, so I’m (mostly) reproducing that content here.

The biggest news is the updated and largely rewritten Arduino firmware source code that powers the microcontroller at the core of the Keyglove design. Since this is an open-source project, it has always been my intention to publish the complete source so that anyone can understand or modify the functionality however they might wish to. However, I am a bit of a neat freak when it comes to code. Well, “a bit” may be an understatement. It’s hard for me to work with or around code that isn’t organized, and/or formatted, and/or documented well, and it’s even harder for me to publish it knowing that others may need or want to use it in their own designs. Before I feel good about handing something to the world, it must pass my own tests for organization, readability, and documentation.

VIDEO: Prototype D Autodesk Inventor COM API Demo

Keyglove #10 – Prototype D Autodesk Inventor COM API Demo from Jeff Rowberg on Vimeo.

This video demonstrates Keyglove Prototype D and the Keyglove Kit v0.4 PCB (v0.5 still pending design completion) along with the alpha Keyglove Manager app integrated with Autodesk Inventor using the COM API for true 3D input. This is just a sample of the kind of thing that can be done with the Keyglove. And, honestly, this isn’t even a very good demo due to the early stage of development of the Manager app and the loose mounting of the older revision of the PCB on the glove.

Actually, Here’s Keyglove Kit v0.4

Actually, Here’s Keyglove Kit v0.4

So, after extolling all of the electronic virtues of the v0.3 Kit PCB only a few days ago, I’ve gone ahead and created a new revision of the board already. It turns out that it can indeed be smaller, without sacrificing any of the existing functionality. In fact, v0.4 is a full 25% smaller even than v0.3, giving us a PCB that is now a mere 46% of the original v0.1 board’s size.

Keyglove Kit Progress

Keyglove Kit Progress

Good news on the kit PCB! I think I’ve got a winning combination of size, layout, and functionality. I just posted Keyglove Update #17 on the Kickstarter project page yesterday which discusses some of what I’m going to explain here, but I’ll summarize that bit again for those of you who don’t follow those updates, and include a bit more technical detail here and there.

Keyglove Kit Initial Development

Keyglove Kit Initial Development

I’ve got quite a backlog of updates for you all, seeing as I’ve been quite busy but haven’t actually written any real blog posts here for over two months. Some of the updates may end up being bundled together, but my goal is to keep them each focused on a single subject to better explain what’s going on. We’ll see. Those of you keeping any eye on the @keyglove Twitter feed and/or the Facebook page have undoubtedly seen the steady stream of quick updates and photos that have been posted, but for those relying only on blog posts, I apologize for the apparent silence.

If you need a quick update without waiting for upcoming posts, check out the two links above—especially the Facebook page—and read through a bit of the history until sometime back around Christmas.
