The “Navigation Thing“ was designed and built by [Jan Mrázek] as part of a night game activity for high school students during week-long seminar. A night-time path through a forest had stations with simple tasks, and the Navigation Thing used GPS, digital compass, a beeper, and a ring of RGB LEDs to provide a bit of “Wow factor” while guiding a group of students from one station to the next. The devices had a clear design direction:
“I wanted to build a device which a participant would find, insert batteries, and follow the beeping to find the next stop. Imagine the strong feeling of straying in the middle of the night in an unknown terrain far away from civilization trusting only a beeping thing you found. That was the feeling I wanted to achieve.”
The Navigation Things (there are six in total) guide users to fixed waypoints with GPS, a digital compass, and a ring of WS2812 LEDs — but the primary means of feedback to the user is a beeping that gets faster as you approach the destination. [Jan] had only four days to make all six units, which was doable. But as most of us know, delivering on a tight deadline is often less about doing the work you know about, and more about effectively handling the unexpected obstacles that inevitably pop up in the process.

[Mathieu] wrote in with his laser target practice game. It’s not the most amazing hack in the history of hackery, but it’s an excellent example of the type of simple and fun things you can do with just a little bit of microcontrollering.
First off, the gun is a broken toy gun that used to shoot something other than red collimated light beams. The Arduino knockoff inside reacts to a trigger pull and fires the laser for around 200 milliseconds. The gun also has a “gas gauge” that fills up with repeated shots and cools down over time. And therein lies the game — a simple race to ten, where each player only has a fixed number of shots over time.
The targets are simply a light sensor, scorekeeping LED display, and a buzzer that builds tension by beeping at you as the countdown timer ticks down. The bodies are made out of 3D-printed corners that connect some of [Mathieu]’s excess wooden goat-cheese lids.
All the code is up on GitHub so you can make your own with stuff that you’ve got lying around the house. The “gun” can be anything that you can embed a laser in that makes it aimable. Good clean fun!
[Dr.Duino] recently completed the latest piece of what he calls “Interactive Furniture” – the GoonieBox. It took over 800 hours of design and assembly work and the result is fascinating. Part clock and part puzzle box, it’s loaded with symbols, moving parts, lights, riddles, sounds, switches, and locked compartments. It practically begs visitors to take a closer look.
The concept of Interactive Furniture led [Dr.Duino] to want to create a unique piece of decor that visitors could interact with. That alone wasn’t enough — he wanted something that wouldn’t require any explanation of how it worked; something that intrinsically invited attention, inspection, and exploration. This quest led to creating The GoonieBox, named for its twin inspirations of the 1985 film The Goonies as well as puzzles from the game “The Room“.
Embedded below are two short videos: the first demonstrates the functions of the box, and the second covers the build process. There’s laser-cut wood, plenty of 3D printed parts, and a whole lot of careful planning and testing.

When every month brings out a fresh console blockbuster game that breaks new boundaries of cinematic immersion in its gameplay, it’s easy to forget that sometimes the simplest of game interfaces can be rewarding.
“Hele Norges Knapp” (“All of Norway’s Button”), is a good example. As you might expect, it’s a button, a large arcade-style one, and the gameplay is simple. Press the button as many times as you can in 30 seconds. It’s a project from Norwegian Creations, and it was produced as a promotion that toured the country for one of Norway’s debit card payment systems.
The blog post and video is frustratingly light on hardware or software details, and their is nothing about it in their GitHub presence. But they tell us that at its heart is a Teensy 3.2 with an audio board, driving the big 7-segment displays for the scoreboard and the WS2801 LED lighting.
The button itself is Adafruit’s 100mm Massive Arcade Button, and given that it was pressed over a million times by eager Norwegians it would seem this project has proved its robustness.
The video below the break has details of construction and of the game in action, and there is another far more corporate promotional video on Facebook featuring a host of Bright Young People honing their button action in a sun-kissed Norway that looks almost tropical. The game itself does look as though it could be an amusing diversion in the same vein as those fairground strength tests.

[Andrew Milkovich] was inspired build his own Super Nintendo cartridge reader based on a device we covered an eternity (in internet years) ago. The device mounts a real cartridge as a USB mass storage device, allowing you to play your games using an emulator directly from the cart.
This uses a Teensy++ 2.0 at its core. [Andrew] had to desolder the EEPROM pins from the SNES cartridge and reverse engineer the pinouts himself, but the end result was a device that could successfully read the cartridge without erasing it, no small accomplishment. The finished cartridge reader is build on some protoboard and we’d like to complement [Andrew] on his jumper routing on the underside of that board.
Of course, the experience of any console is just not the same without the original controller. So [Andrew] went a step further and made his own SNES controller to USB converter. This had the venerable Atmel ATmega328 at its core, and can be used separate from the cartridge reader if desired.
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.

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.
