Robotic Tank (June 2016)

The robotic flamethrower tank is nearing completion. I redesigned quite a bit of it so it's now using more 3D printed components, and it's now controlled by a wireless Xbox 360 controller instead of with an Android app over Bluetooth.

Here's how it currently looks. If you want to see a video of the tank plus additional photos and details, check out the article on my Wordpress blog.

Arcade Cabinet (March 2016)

After thinking about it for years, I finally decided to build an arcade cabinet. It's powered by a Raspberry Pi and this project helped me get much more familiar with the Pi's, so my next project might be something related to the Internet of Things (IoT). The layout includes a joystick, a trackball, 6 action buttons and 2 buttons on the side for Start & Select/Insert Coin.

I've included a few pictures below, but if you want more information head over to the detailed overview on my Wordpress blog.

Robotic Tank Concept(Early 2015)

Things are progressing slower than planned, but overall it's been a fun project. I decided to swap out the wheels for tank tracks, and I replaced the wired controls with an Android app that communicates over Bluetooth. I also started doing some 3-D printing for components that I couldn't find a good way to make any other way.

The next step will be to solve some minor glitches with the tank treads, then maybe work on a turret to install on the top of the tank. Who knows, maybe my design will be so awesome that the military will want to give me a contract to build some prototypes!

Here's the updated robot:

Gears are bike sprockets with every other tooth filed off.
