Electroshock Timer Will Speed Up Every Game of Settlers of Catan

The fun of playing Settlers of Catan is only matched by the desire to punch your friend when their turn drags on with endless deliberating. [Alpha Phoenix] has solved that quandary of inefficient play by building the Settlers of Catan: Electroshock Therapy Expansion.

[Alpha Phoenix] is holding back on the details of the device to forestall someone trying this at home and injuring themselves or others, but there’s plenty to glean from his breakdown of how the device works. An Adafruit Trinket microcontroller connects to a single pole 12 throw switch — modified from a double pole six throw rotary switch — to select up to six different players (with the other six positions alternated in as pause spaces) and the shocks are delivered through a simple electrode made from a wire hot glued to HDPE plastic from a milk jug. The power supply is capable of delivering up to 1100V, but the actual output is much less than that, thanks to its built-in impedance of about 2.5M Ohms, as well as added resistance by [Alpha Phoenix].

To define what constitutes a ‘long turn,’ the Trinket calculates the mean of up to the first 100 turn lengths (instead of a static timer to accommodate for the relative skills of the players in each game) and zaps any offending player — and then repeatedly at a set time afterwards — to remind them that they need to pick up the pace.

The Prettiest Darn Arcade Cabinet You’ll See Today

We see an awful lot of arcade cabinets around here, and so it’s pretty unusual for a build to get much more than a second glance. But, this beauty is just too good not to mention. The entire build, named “Ready Player One” as a nod to the engrossing Ernest Cline novel, is detailed in [scoodidabop’s] post on Reddit.

Staying In and Playing Skyrim Has Rarely Been This Healthy

Looking to add some activity to your day but don’t want to go through a lot of effort? [D10D3] has the perfect solution that enables you to take a leisurely bike ride through Skyrim. A standing bicycle combines with an HTC Vive (using the add-on driver VorpX which allows non-vr enabled games to be played with a VR headset) and a Makey Makey board to make slack-xercise — that’s a word now — part of your daily gaming regimen.

The Makey Makey is the backbone of the rig; it allows the user to set up their own inputs with electrical contacts that correspond to keyboard and mouse inputs, thereby allowing one to play a video game in some potentially unorthodox ways — in this case, riding a bicycle.

Setting up a couple buttons for controlling the Dragonborn proved to be a simple process. Buttons controlling some of the main inputs were plugged into a breadboard circuit which was then connected to the Makey Makey along with the ground wires using jumpers. As a neat addition, some aluminium foil served as excellent contacts for the handlebars to act as the look left and right inputs. That proved to be a disorienting addition considering the Vive’s head tracking also moves the camera. Continue reading “Staying In and Playing Skyrim Has Rarely Been This Healthy”

Minecraft Trojan Horse Teaches Kids to Love Electronics and Code

Kids love Minecraft, and a clever educator can leverage that love to teach some very practical skills. The summer class offered by the Children’s Museum in Bozeman Montana would have blown my mind if such a thing existed when we were younger. (Rather than begging one of the dads in my Boy Scout Troop to pirate Visual Studio for me, which was delivered in the form of an alarmingly tall stack of CDs.) The kids in Bozeman get to learn hardware, software, their integration, and all while playing Minecraft.

Minecraft is an immersive universe that has proven to suck in creative minds. It’s the bait that pulls the kids into the summer class but Serialcraft delivers on making the learning just as addictive. This is accomplished by providing students with physical objects that are tied to the Minecraft world in meaningful ways we just haven’t seen before (at least not all at one time). On the surface this adds physical LEDs, toggle switches, potentiometers, and joysticks to the game. But the physical controls invite understanding of the mechanisms themselves, and they’re intertwined in exciting ways, through command blocks and other in-game components that feel intuitive to the students. From their understanding of the game’s mechanics they understand the physical objects and immediately want to experiment with them in the same way they would new blocks in the game.

The thing that makes this magic possible is a Minecraft mod written by [John Allwine], who gave us a demonstration of the integration at Maker Faire Bay Area 2016. The mod allows the user to access the inputs and output of the Arduino, in this case a Pololu A-Star 32U4, from within Minecraft. For the class this is all packaged nicely in the form of a laser cut controller. It has some LEDs, two joysticks, buttons, potentiometers, and a photosensor.

As you can see in the video below the break, it’s really cool. The kids have a great time with it too. For example, [John] showed them how they can attach their unique controller to a piston in the world. Since this piston can be controlled by them alone, they quickly figured out how to make secret safe rooms for their items.

Another troublesome discovery, was that the photo transistor on the controller set the light level in the game world by altering the time of day. Kids would occasionally get up and change the world from day to night, by turning the lights in the room on or off. A feature that has a certain appeal for any Minecraft player, is rigging one of the LEDs on the controller to change brightness depending on proximity to a creeper.

There’s a lot more to the library, which is available on GitHub. The kids (and adults) have a great time learning to link the real world with the world’s most accessible fantasy world creation kit.  Great work [John]!

Save a Spaceship with Spacehack!

York Hackspace needed a demonstration piece to grace their stand at Maker Faires and similar events. Their solution was Spacehack, a multi-player control console based starship emergency simulator game. Each Spacehack player has console with a selection of displays, switches, dials, and levers. Players must operate their controls in response to a series of sometimes confusing commands the game supplies them from their fellow crew members. Each wrong move brings the disaster-prone ship closer to destruction, and the aim is to keep it spaceworthy for as long as possible. The result is an engaging and addictive draw for the hackspace.

Behind the brilliantly designed consoles, silver ducting and pyramidal hub box the game relies on a Raspberry Pi acting as a server and a Beaglebone Black for each player. All resources can be found on York Hackspace’s GitHub repository. The hackspace has a selection of videos on the Spacehack website, the one below the break shows the game as well as a montage of its construction. Continue reading “Save a Spaceship with Spacehack!”

Snake On A BBC Micro:bit

The first of the BBC Micro Bits are slowly making their ways into hacker circulation, as is to be expected for any inexpensive educational gadget (see: Raspberry Pi). [Martin] was able to get his hands on one and created the “hello world” of LED displays: he created a playable game of snake that runs on this tiny board.

For those new to the scene, the Micro Bit is the latest in embedded ARM systems. It has a 23-pin connector for inputs and outputs, it has Bluetooth and USB connectivity, a wealth of sensors, and a 25-LED display. That’s small for a full display but it’s more than enough for [Martin]’s game of snake. He was able to create a hex file using the upyed tool from [ntoll] and upload it to the Micro Bit. Once he worked out all the kinks he went an additional step further and ported the game to Minecraft and the Raspberry Pi Sense HAT.

[Martin] has made all of the code available if you’re lucky enough to get your hands on one of these. Right now it seems that they are mostly in the hands of some UK teachers and students, but it’s only a matter of time before they become as ubiquitous as the Raspberry Pi or the original BBC Micro.  It already runs python, so the sky’s the limit on these new boards.

Connect Four Robot Uses Raspberry Pi

Most people play games for entertainment. Hackers build robots to play games for entertainment. That’s what [piandchips] did. He used a Raspberry Pi and a MeArm kit to build a Connect 4-playing robot. The robot–named 4-Bot–has to do two things: the first is it has to be able to manipulate the pieces. Secondly, it has to be able to see the board. The MeArm imbues 4-Bot with the manipulation ability, and a clever scanning system does the trick.
