The GoonieBox challenges guests to solve its riddles

Friday, October 21st, 2016

Inspired by The Goonies movie and The Room game, Guido Bonelli has constructed a piece of Arduino-controlled interactive furniture to entertain his guests.

After what appears to be a massive amount of work involving 3D printing, laser cutting, wiring, and programming, Bonelli has come up with a puzzle box that shouldn’t need any explanation. Using button presses and other interactions with it, participants are able to unlock a treasure box in the bottom, a working wooden safe! (more…)

Cutting cable with scissors and Arduino

Thursday, October 20th, 2016

2PrintBeta solves the problem of cutting multiple cables with an innovative scissors setup.

At times, the 3D printing and engineering company 2PrintBeta needs to cut wires and other assorted materials to length. Sure, they could simply cut them by hand, but that takes time and their business is growing. An industrial cable cutter is quite expensive, so being an engineering company, they decided to make their own using a rather rugged pair of scissors actuated by a bolt attached to a drive disk.

For this operation, wire feeding is done by a pair of 3D-printed wheels, and the “brains of the operation” is provided by an Arduino Mega using stepper motor drivers. (more…)

Square Off is a chess board with a high-tech twist

Monday, October 17th, 2016

If you love chess, but aren’t thrilled about playing it on an app, the InfiVention team has just the board for you.

The origin of the game chess is a fascinating and somewhat unknown tale, stretching continents and many hundreds of years. In the last 25 or so years, however, it has gone from a game played on a beautiful board with finely crafted pieces, to something played on a computer or smartphone. Perhaps this is a good thing, since finding competition is as easy as signing into the correct game.

On the other hand, this type of play looses a lot of charm, and you can’t exactly pass the app on your beat up smartphone to your kids one day. Attempting to fill in the gap is the amazing automated board called “Square Off.” With an Arduino Mega 2560 at its core, it automatically moves the pieces, and detects where you move, allowing you to play in the real world with someone remotely–even if he or she is merely using a tablet!

A sheet metal Arduino MP3 alarm clock

Wednesday, October 5th, 2016

Wake up to your favorite tunes using this beautiful sheet metal alarm clock!

If you need to get up for work, class, or simply to avoid wasting the day away, setting an alarm is the obvious solution. Sure, you could buy a clock or just use your phone, but if you build Dejan Nedelkovski’s Arduino-based device, you can be reminded of your awesome Maker skills every morning. (more…)

Build your own electronic drum kit using an Arduino Mega

Wednesday, October 5th, 2016

If you’d like to save some money on a drum kit, this one is made using an Arduino Mega, MDF, and even a left sandal!

Drum kits can be quite expensive, Maker Victor Herrero has created his own nine-piece set with readily-accessible components. Arduino code was modified from another project by Evan Kale, and is available for download. Although electronics is discussed, the Instructables article focuses on how to physically make the set, mostly out of MDF.

The results are something that looks quite different than a “normal” drum set, with hexagonal drum pads and a flip-flop for hi-hat control! You can find the project on Instructables here, and the code that you’ll need on its GitHub page.

Building a sweet plastic MIDI controller

Monday, September 26th, 2016

With parts from a bathroom organizer and arcade buttons, Alex “GlacialGeyser” made his own MIDI machine.

MIDI controllers can be great instruments to supplement your musical skills. As seen in the video below, Alex’s project is no exception, and he’s able to produce some really beautiful music using it and a keyboard. Physically, he created this out of plastic parts from a bathroom organizer and a cutting board that he cut using mostly handheld power tools. An Arduino Mega serves as the brains of the operation along with two 75mm 10k faders, two 10k knobs, pitch bend and modulation wheels, and a couple of LEDs.

The build is finished off with a splattered paint effect and nearly a whole can of clear coat. Programming the device was a challenge, but it seems Alex gained some useful knowledge for next time! (more…)

An Arduino VU meter for classrooms

Friday, September 23rd, 2016

With his beautifully-colored classroom “noise-o-meter,” Mr. Jones knows when things are getting out of hand.

When you were in school (or if you are in school) the teacher likely told the class to be quiet, perhaps repeating him or herself over an over during the day. The teacher, however, likely never really defined what is good and bad. Mr. Jones has finally solved this issue by creating a classroom “noise-o-meter” using an Arduino, an electret microphone, and a programmable LED strip. In order (apparently) too keep the class in line, noise is simply marked as green for “expected,” amber for “louder,” and “red” for too loud which corresponds nicely with more “traditional” VU meters.

An animatronic talking takeout container

Thursday, September 22nd, 2016

An Arduino plus fake food and audio capabilities equals something truly unique!

Randy “randofo” Sarafan had an idea when he was in college: a takeout container that talked. To the world’s great benefit, now that he knows about electronics, he finally made this dream a reality. Using an Arduino Mega with a Seed Studio Music Shield, he was able to coordinate the movements of a servo and thus the lid of a box with the audio coming out of a speaker. After attaching googly, or “googily” eyes, and modifying a fake serving of spaghetti, he had something that should be quite entertaining! (more…)

The MR-808 is a robotic drum “synthesizer”

Monday, September 19th, 2016

The MR-808 robotic drum machine looks like a gigantic Roland synthesizer, but plays with real instruments!

The Roland TR-808 was released in 1981 and was meant to replace a human drummer for practice purposes, but was instead used to produce music itself, helping to birth the electronic, techno, and hip hop genres. Moritz Simon Geist and the Sonic Robots collective, however, decided to turn this on its head, with a machine made to look like a gigantic ‘808, but containing real instruments.

With a variety of hardware, including an Arduino Uno and Mega, an audience can program the MR-808 using a tablet and get down to the grooves they create themselves!


Connected question mark hopes to spark 1 million conversations

Wednesday, September 7th, 2016

Suicide prevention charity R U OK? has partnered with digital innovation agency Fusion to create a fully-connected device in the form of a question mark with hopes of sparking a million conversations throughout Australia. Similar to the Olympic Torch, Quentin will be passed from person to person as it makes its way from town to town starting on Thursday, September 8th.

But unlike the Olympic Torch, the route is not planned. Instead, the journey is determined by the challenge it issues to each new keeper motivating them to reconnect face-to-face with people in their lives. (more…)
