Control a tracked robot with your mind (or joystick)

Monday, January 16th, 2017

Whether you choose to control this vehicle with your mind or a joystick, the camera mounted on it will give you a new view of the world.

Maker “Imetomi” was inspired to create a tracked robot after he was able to salvage a camera off of a cheap drone. This became the basis of his FPV setup, which he fitted onto a little tracked vehicle. Although this would have been enough for most people, in addition to building a joystick-based controller, he also made it work with a brainwave headset. (more…)

An Arduino-powered automatic guitar footswitch

Friday, January 13th, 2017

If remembering to hit your foot pedal at the right time during shows is a challenge, this device will take care of it for you.

As creator Franco Molina points out, there’s a lot to worry about when playing guitar in front of an audience. Actually playing is one thing, but you have to pay attention to the crowd, move around on stage, make sure you don’t have any wardrobe malfunctions, and… hit a footswitch to change between clean and distorted channels when appropriate.

Molina’s device may not be able to help you with everything on that list, but by listing to a specially encoded ‘click track’ from a computer or MP3 player, it can automatically switch amplifier modes when appropriate. It does this by using an Arduino Uno along with an amp to listen to the track, then switch a relay to simulate a footswitch. (more…)

These students created their own Overwatch VR rig

Thursday, January 12th, 2017

A group of high school students in South Korea have created a multi-part rig that lets them play Overwatch in virtual reality.

Their console, which resembles somewhat of a Virtuix Omni treadmill, enables users to move around the battlefield by leaning in whichever direction they want to go, to fire and reload their weapon with a custom toy gun controller, and even to hit things by punching the air.

As you can see in the video below, the setup consists of a Samsung Gear VR headset, a smartphone, Arduino boards, an IMB sensor, a button, a ball bearing, a PC, a motion detection device, and a copy of Overwatch. (more…)

Attachment is like a modern-day message in a bottle

Wednesday, January 11th, 2017

If you want to reach out to someone, you could always pick up your phone and send a text. But if you’re seeking something a bit more random and indirect, one idea would be to write and attach a message to a biodegradable balloon using Swiss designer David Colombini’s “poetic machine.”

Colombini’s Attachment project allows you to do just that, by dispatching digital notes, images or videos gleaned from the Internet into the atmosphere. Once the Arduino Mega-driven device receives this input, the message is laser-etched on a thin piece of balsa wood, then released into the air (though a human has to ‘reload’ after five launches). Word space is limited to a Twitter-esque 120 characters, but the finder of the balloon can access any additional content that you include through a code on the project’s website. (more…)

Scare away unwanted guests with an eye-moving portrait

Wednesday, January 11th, 2017

There are certainly many ways to generate an old-looking portrait with moving eyes, but this method from Sonic Robots is simple and seems quite effective. The basic formula is to buy a Victorian-like frame, get a picture of a loved/hated/random person (preferably tweaked to resemble an antique oil painting), then put a strip of paper with eyes printed on it behind the person’s eye sockets.

This eyeball strip is pulled by a servo via a fishing line, and importantly, a rubber band keeps tension on it from the other side. This allows it to quickly snap back into place, creating an effect where the eyes randomly move then stay in place for a while, hopefully causing someone to question his or her sanity. (more…)

Watch an Arduino Mega-based robot play the bagpipes

Tuesday, January 10th, 2017

Using gigantic hands scaled up from a prosthetic design, “XenonJohn” can now hear the sweet sounds of Scotland whenever he wants.

Seeing this invention, you might note to yourself that most instrument-playing robots don’t actually bother to have realistic—if huge, at 171% normal print size—hands attached. Then again, you probably haven’t seen a robot configured to play the bagpipes.

The robot named Ardu McDuino plays the bagpipes, or rather the chanter part that is manipulated with one’s fingers, using actual prosthetic fingers to cover the holes. It also has a less-realistic “thumb” to cover a hole on the back. (more…)

Cozy Coupe toy car retrofitted with Arduino

Tuesday, January 10th, 2017

Using an Arduino Uno along with an Adafruit Wave Shield, Brent Chapman added more features to the Little Tikes Cozy Coupe including a push-to-start ignition and a sound system.

Although Chapman notes that the Coupe comes with some onboard entertainment options, he thought “his client” deserved something a bit more high-tech. This meant that he retrofitted the classic toy with several pushbuttons that allow him to select a fun song to play and replaced the key with a giant arcade button. He also 3D-printed a replacement hood for the car to cover the electronics, since the original was modified to fit them inside. (more…)

Arduino car alarm honks for help!

Friday, January 6th, 2017

Sure, if you’re going to get a new ride, a model from the twenty-teens would be nice, but for hacking purposes, the simplicity of an older cars makes modification fairly simple. It also makes hot-wiring easy, and as they don’t generally have an alarm system, these vehicles are often targets for theft.

After his friend’s VW Beetle was stolen, Instructables user Ben Schroeder (aka “Pantopush”) decided that he needed to protect his 1966 Bug. So, as any Maker would do, he took matters into his own hands with a GPS-enabled Arduino Uno in a locked glove compartment. (more…)

Turn an Atari 2600 into an electronic drink racer and timer

Friday, January 6th, 2017

The next time you and your friends want to see who can chug beer (or a non-alcoholic beverage for the younger crowd) the fastest, you may want to try building your own Cider Racer 2600–an electronic racing platform and timer for competitive drinking.

Created by YouTuber “MonkeyBOX Entertainment” for an annual Christmas party, the project consists of a broken Atari 2600 retrofitted with an Arduino Mega, two 4-digit 7-segment displays, some LEDs, wires, and other miscellaneous parts. A pair of custom coasters were constructed using force-sensitive resistors, soft springs, rubber actuators, and three layers of CNC-cut materials: acrylic bottom plate, brushed aluminum center, and acrylic spacer to make it level with top of the old gaming console.

This guitar-playing robot performs American folk music

Thursday, January 5th, 2017

Inspired by a statement written on Woody Guthrie’s guitar, This Machine Kills Fascists (TMKF) is an Arduino Mega-based, guitar-playing robot that performs traditional American folk music on a portable stage. Sheet music with the song lyrics are printed and left on the benches set up in front of the stage, while audience members are encouraged to sing along to the tunes.

Developed by engineer Dustyn Roberts, artist Troy Richards, and designer Ashley Pigford, TMKF is combines the analog tradition of folk music and digital technology of robotics. (more…)
