Control the Real World with an Arduino-Enabled Minecraft Mod

Minecraft modding has become almost as popular as the block-based game itself, with tons of editors and tools available to create new kinds of blocks, mobs, and weapons. And now, with this mod framework that can talk to an Arduino, modders can build blocks that break out of the Minecraft world to control the real world.

While turning on a light from Minecraft is not exactly new, the way that MCreator for Arduino goes about it is pretty neat. MCreator is a no-code framework for building Minecraft mods, which allows modders to build new game capabilities with a drag and drop interface. The MCreator Arduino toolkit allows modders to build custom Minecraft blocks that can respond to in-game events and communicate with an Arduino over USB. Whatever an Arduino can do – light an LED, sense a button press – can be brought into the game. It’s all open-source and free for non-commercial use, which is perfect for the upcoming STEM-based summer camp season. We can think of some great projects that would really jazz up young hackers when presented through a Minecraft interface.

Hackaday Links: April 19, 2015

Bang & Olufsen have made some pretty amazing equipment for a long, long time. That last part can become a problem. [Oliver] found the electrolytic caps on his Beomaster 2400 were causing problems. He completely recapped the unit, all the electrolytics anyway, and the pictures of the process are nothing short of eye-candy.

The closure of the Bacman forums marks the end of an era. For years this has been among the top (okay, it’s definitely been the top one but we don’t want to start a flamewar) sites for handheld and console modding. Here’s just one random example of the many projects we covered from that community (note that main link is now sadly 404). The closure message cites the near-absolute death of modding. We haven’t thought about it much, but these mods were futuristic. Then smartphones.

Fans of How It’s Made and 3D printing will want to tune in on April 30th at 9pm EST. The show does a fantastic job of showing off the amazing story behind how all the stuff in our lives comes to be visited LulzBot in Loveland, Colorado for a segment on the manufacturing process of a 3D printer.

We’re not sure why we didn’t lead with this: All celebrate, for humanity is saved! The secret behind getting something out of nothing has been discovered. This reactionless generator has been tested at efficiencies as high as 250%. We’re working on a way to bottle all that extra juice and sell it at outrageous prices.

The thing about free energy is that you become dependent on it. What if the laws of physics return from vacation and the thing stops working? Then you have a robot apocalypse with all kinds of hidden messages and puzzles in it.

Dual-channel, variable voltage test box is a busy console modder’s dream


It seems like [Chris Downing] is always up to something new. If he’s not keeping busy by creating slick portable iterations of previous-gen gaming consoles, he is dreaming up ways to make his modding life a bit easier.

Recently while working on a Nintendo controller designed to control three different consoles, [Downing] found his desk buried in a pile of power supply and A/V cabling. Annoyed with his growing rat’s nest, he decided to build a universal power supply that would allow him to quickly switch between consoles with little effort.

He dug up an old PC power supply, and fed it into a LED control box built for cars. [Downing] then mounted an array of nine rocker switches on the box, adding A/V inputs and outputs along the way. A set of voltage regulators hidden inside allow [Downing] to dial in whatever custom voltages he might need at the moment.

The test box should come in pretty handy as [Downing] pursues even more modding projects in the months to come. In the meantime, be sure to check out the video below where he covers the finer points of the device’s design.
