A touchless MIDI controller for your electric guitar

Arduino Team October 17, 2016

If guitar effects pedals aren’t really your thing, perhaps Evan Kale’s touchless MIDI controller will fit the bill.

Using an Arduino, along with a Colpitts oscillator and some other electronics, Kale has come up with a rather unique interface for his guitar. Instead of using a foot pedal, he put a strip of aluminum foil inside of a fingerless glove, then attached a homemade metal detector coil and circuit to the back. Read the rest of this entry »

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

Arduino Team October 17, 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!

Smartwatch prototype turns your wrist into a joystick

Arduino Team October 17, 2016

Although smartwatches were designed to be an easy-to-use alternative for your smartphone, interacting with their touchscreens still requires your opposite hand to be free. So what do you do when you’re carrying a bag of groceries or holding onto a bus handle?

This is the problem a Dartmouth-led team set out to solve with WristWhirl, a smartwatch prototype that uses the wrist wearing the device as a joystick to perform common touchscreen gestures with one-handed continuous input, while freeing up the other hand for other tasks.

WristWhirl was built using a two-inch TFT display and a plastic watch strap equipped with a dozen infrared proximity sensors and a piezo vibration sensor, which is connected to an Arduino Due board. Commands are then made by moving the hand as if it were operating a joystick, while a finger pinch turns the sensors on/off to indicate the start or end of a gesture.

University of Washington develops a self-driving tricycle

Arduino Team October 13, 2016

Autonomous cars seem to get all of the attention, but this autonomous trike is hoping to take things in a different direction.

With the support of Amazon’s Catalyst program, as well as from software company Kerika, University of Washington Bothell professor Tyler Folsom’s self-driving tricycle aims to help us lessen our dependence on fossil fuels. It’s a neat platform in its current form based on a recumbent tricycle.

As seen in the video below, it’s taken one of the first steps toward driving itself, taking a command to drive in a circle without direct control by an operator. Read the rest of this entry »

Collector is “a kind of reality re-mixer”

Arduino Team October 13, 2016

For his latest project, Dmitry Morozov (aka ::vtol::) has created a robotic machine that uses a microphone to record sounds from its surrounding environment, selecting only the loudest ones. Then, the aptly named “Collector” pieces these noises together in the order they were recorded to form an algorithmic  composition.

First, the Collector records the sounds until it has gathered 100 samples. From there, it plays the result as a loop through a pair of speakers for one minute, so they can be heard by those nearby. While in this mode, the recording stops. After that, it erases everything and begins a new search. Read the rest of this entry »

Ping Pong FM is a fun, musical take on table tennis

Arduino Team October 12, 2016

If you thought table tennis was hard enough, wait until you see what Mark Wheeler and a team of designers have come up with. Ping Pong FM puts a Guitar Hero-like spin on the classic sport.

However, unlike the actual game, Ping Pong FM is more collaborative than competitive. That’s because players must hit the ball back and forth to keep the music going. Select your paddle, choose your song, and serve. Rally too slowly, or miss the ball, and the music will wind down. Rally at the correct tempo and the party is on. As you can imagine, faster tunes like “Intergalactic” by the Beastie Boys or “Milkshake” by Kelis are more challenging. Read the rest of this entry »

Check the traffic autonomously on a modified clock

Arduino Team October 11, 2016

Using an Arduino and 1Sheeld, Integreight embedded engineer Eslam Ali set his office clock up to preview the traffic going home.

If you work in a traffic-prone area, there’s always a debate as to whether you should go home at the normal time or wait a few minutes to leave and avoid the traffic. To help make that decision, Ali likes to check the traffic before heading out. This might be fairly simply using a computer or smartphone, but doing so autonomously would be even better.

In a clever feat of automation, he embedded 12 RGB LEDs in a simple IKEA clock. These were then controlled by an Arduino Uno, using a 1Sheeld device to access the Internet through his smartphone. If traffic is bad, it displays as red, then blinks green when it’s time to go! A clever application in itself, something like this could be expanded for numerous uses, perhaps even involving animated lights. Read the rest of this entry »

This Arduino G meter shows how fast your car really is!

Arduino Team October 11, 2016

Using an Arduino with an accelerometer, this handy display lets you know how “extreme” your driving really is!

Modern cars tell us all kinds of information about how our vehicles are working and how you are driving. One thing that is generally missing is a display that tells you how many “G’s” (or how much you are pushed back into your seat) your car is pulling. With this clever setup, you can know how much force your tires are putting to the ground (neglecting body-roll factors) in both straight-line acceleration, braking, and even side-to-side turning.

The AtHeart 4Duino combines Arduino, Wi-Fi and touchscreen

Arduino Team October 11, 2016

A new season, a new partner! We’ve had our sights set on 4D Systems’ touchscreen product for quite some time, and we’re excited to finally introduce that this Arduino and Genuino-compatible product is joining the AtHeart program. The 4Duino-24 is a 2.4-inch, 240×320-pixel Intelligent Display Module with Wi-Fi capabilities.

“For years Arduino/Genuino users have been taking advantage of our Intelligent Display Modules for adding graphical user interfaces with touch capability to their applications. With the 4Duino-24 we wanted to make something a bit more special and combine some of the more popular shields and the ATmega32U4 into a compact easy to use package. We are delighted to become part of the AtHeart program and very much look forward to seeing a full variety of applications running on the 4Duino-24.” – Markku Riihonen, Products and Business Development Manager, 4D Systems.

Perfect for your next creative IoT project, the 4Duino-24 runs on an ATmega32U4 MCU and is powered by the 4D Systems PICASO Graphics Processor that offers an array of display functionality and options for any designer and Maker. The 4Duino-24 also includes the popular ESP8266 module, which is pre-programmed with the AT command set firmware enabling the 4Duino to have Wi-Fi functionality right out of the box.

Beyond that, the 4Duino-24 is equipped with an onboard microSD connector and headers in the layout of an Arduino, including power pins (5V, 3.3V, GND and VIN), 20 digital I/O pins—seven of which can be used as PWM outputs, while 12 pins have analog input capabilities.

The 4Duino-24 can be programmed using the standard Arduino IDE or the 4D Workshop4 IDE and its three new 4Duino-based development environments with the added dimension of graphics. Creating Arduino GUIs doesn’t get any easier!

Ready to get started? You can watch 4D Systems’ 10-minute video below, as well as check out its product page here. The 4Duino-24 is available as a starter kit and standalone module.

Galaga revived as a 4/5 scale MAME machine

Arduino Team October 7, 2016

This arcade machine helps creator Alex Weber relive arcade memories, but is slightly easier to move than a full-sized “cab!”

Galaga is one of Weber’s–and many others’–top five arcade games. Easy to learn, but difficult to master, it was just asking to accept your money and time! Now though, using a Raspberry Pi and MAME software, you can have this and other old-school games at your disposal. Weber built a cabinet for this purpose around an old CRT television slightly smaller than original size.

In order to keep from having to fool with the TV every time it switched on, he made an automated remote control with an Arduino and IR LED that sends signals to turn it on and switches the TV to AV mode. Read the rest of this entry »
