Pickaxe Controller Is Great For Minecraft, Just Aim Carefully

October 9, 2019 by 8 Comments

Minecraft started out as a lovable indie game, and became an unstoppable billion-dollar juggernaut in a remarkably quick fashion. Over time, it’s become a favorite among modders and those that seek to explore what’s possible with the game. [Eric] decided that the game could be more immersive, and built this awesome pickaxe controller.

The controller is built around an off-the-shelf Minecraft pickaxe toy; a popular piece of merchandise given the tool’s importance in the game. [Eric] added an Arduino, an accelerometer, and buttons. This lets the controller act as a mouse, allowing the user to control the camera by moving the pickaxe. The buttons unlock further functionality, with the red button allowing the user to mine by swinging the axe. Reportedly this is a lot of fun, albeit tiring in long sessions. Other features are still controlled by the keyboard, such as movement and accessing inventory screens. We’d love to try it out; carving out a tunnel block by block would be quite satisfying after all the exertion!

[Eric] is actually giving the controller away to a lucky subscriber, so head over to the Youtube video if you’d like a shot to own the nifty pickaxe. We’ve seen other advanced Minecraft controllers before, too. Video after the break.

The TinyG Motion Controller

September 24, 2014 by 31 Comments

When you go to a trade show of any kind, you’re expecting cool demos in the booths. At Maker Faire, there were plenty, but one of the most hypnotic was a robot built around Synthetos’ TinyG motion controller.

The demo was simply a large CNC gantry moving a ball bearing around on a string. The gantry moved in the X and Y axes, and the miniature wrecking ball was spooled and unspooled in the Z axis. The ball move around the space, coming to a complete stop without any swaying. There were even a few clear plastic tubes that the ball fell in, and popped out of without raising or lowering the string. It’s the height of motion controller coolness, all made possible with the TinyG.

The TinyG was one of a few motion control and CNC boards found at the faire. In its base configuration, it has 6 axes of motion control, RS485 to network several boards for crazy machine configurations, and a suitably powerful processor to do everything correctly.
