Save the date for Arduino Day 2017: April 1st

Arduino Team February 13, 2017

For the fourth year, we invite the open source community to join us in celebrating Arduino’s birthday on Saturday, April 1st!

Arduino Day is a 24-hour-long worldwide event – organized by our team and the community – where people interested in Arduino can get together, share their experiences, and learn more about the platform through all sorts of activities, tailored to local audiences. Participation is open to anyone, from young Makers and students to professional engineers and designers.

More than 330 were held by Arduino enthusiasts across the globe in 2016. This year, we are hoping to make that number 500! If you want to organize Arduino Day festivities of your own, please fill out the online form and submit your proposal here by March 11th.

In the coming weeks, be sure to visit the official website to learn more or find an event in your area. And don’t forget to post, engage, and follow along on social media using the hashtag #ArduinoD17!

Replace a microwave’s beep with the Windows XP startup sound

Arduino Team February 10, 2017

When your microwave is done with its food, it generally beeps… and beeps… and beeps. Though you definitely want to know when your frozen burrito is edible, if you get to it right when it wants, things can get quite annoying. Tim Gremalm decided to do something about it, and replaced the buzzer in his appliance with an Arduino Nano, an amplifier, and small speaker.

His initial speaker/amplifier combination wasn’t loud enough so he replaced it with more appropriate options. After this hack, he now has something that can play a more pleasing tone—in his case, the Windows XP startup sound—and do so only once!

An extremely well thought out marriage proposal with Arduino

Arduino Team February 9, 2017

Once solved via a series of brain teasers and a physical challenge, this puzzle box opens to reveal an engagement ring.

When proposing to your significant other, the normal course of action is to hopefully do something romantic, get on one knee, and present your hopefully soon-to-be fiancé with a ring. David Hoskins however, apparently confident that his girlfriend would have the will as well as the mental and physical capacity to pass his test, instead created “The Box.”

This device put the user through challenges including a water weight puzzle that will be familiar to Die Hard fans, an audio puzzle, a visual puzzle, and even an endurance challenge involving an exercise bike. Of course, if his girlfriend failed to complete the puzzle, that would really ruin the setup, so Hoskins, who got the idea for the game while studying for a masters degree in user experience design, tested things thoroughly beforehand.

A DIY Laser Scanning Microscope

Arduino Team February 9, 2017

With a DVD pick-up, an Arduino Uno, a laser, and an LDR, Instructables user “Venkes” has managed to create a DIY Laser Scanning Microscope (LSM).

A laser microscope works by shining a beam of light on a subject in an X-Y plane. The intensity of the reflected light is then detected by a photoresistor (or LDR) and recorded. When the various points of light are combined, you get an image.

Obviously you need a very small laser beam. Since a DVD laser unit has to work with the extremely small bit markings on these disks and has coils to steer the lens built-in, this seems like a logical choice to use with a custom microscope. Though it took quite a bit of effort to make, it’s capable of 1300x magnification and attaining a resolution of 65,536 pixels (256 x 256) in an area of .05 x .05mm. Results start around 3:00 in the video below. Read the rest of this entry »

Teleknitting: TV-based string art

Arduino Team February 8, 2017

Have you ever wondered what television would look like if transposed onto string and wrapped around another object? If so, you’re not the only one, as shown in this teleknitting sculpture.

Although it’s hard to say where the idea for this piece came from, Moscow-based artist ::vtol::’s teleknitting installation resolves a TV signal down into one pixel by lowering its resolution in eight steps. This process is displayed as video on an Android tablet, and the results are transferred to thread via a unique dying mechanism involving “dye arms.” Read the rest of this entry »

Start your day with Nerf target practice!

Arduino Team February 7, 2017

If you need motivation to actually wake up rather than sleep more, this Nerf target clock from “Normal Universe” could be a great solution!

For many of us, traditional alarm clocks have given way to smartphones, but the concept is still the same: an annoying sound, followed by either waking up, or hitting the virtual snooze button just… one… more… time. On the other hand, when this alarm goes off, you need to shoot it with a Nerf gun in order to silence it.

The alarm/target works using a piezoelectric sensor attached to the clock’s housing. When the alarm sounds, if it senses a dart hit by counting the signal pulses generated, it turns off. Ingeniously, and perhaps annoyingly, it can tell if it’s tapped by a finger, and not respond accordingly! Read the rest of this entry »

Haptic game controller UnlimitedHand joins AtHeart!

Arduino Team February 7, 2017

unlimitedhand

We are excited to announce that UnlimitedHand is now an officially licensed Arduino AtHeart product. Created by Japanese startup H2L, the wearable controller straps around your forearm like an Ace bandage and allows you to actually touch and feel things within the gaming world.

UnlimitedHand consists of a 3D motion sensor, an array of muscle sensors, a multi-channel electronic muscle stimulator, and a vibration motor, which together, enable you to interact with objects and characters in VR. It does this by syncing the movement of a user’s hand and fingers with its virtual counterpart, and contracting the muscles on the wearer’s forearm to simulate haptic feedback.

With UnlimitedHand, not only will you be able to experience the ricochet of a gunshot or pet animals, but also hack various customized gestures thanks to its full compatibility with the Arduino IDE.

According to H2L:

Arduino, with their commitment to open-source, has reached out with their technology to muster a great force of Makers and inventors. This omni-present community has no doubt supported us in many ways during the development of UnlimitedHand. By joining the program, we can now present our results back to the community.

UnlimitedHand–which surpassed its Kickstarter goal in less than a day–is now available for purchase on the Arduino online store and Amazon.

Converting a coffee maker into a 3D printer

Arduino Team February 6, 2017

Heavy duty coffee makers are good for, well, making coffee. On the other hand, if you were to look at the frame without the preconception of what it can do, you might notice that there is space on top where equipment could be attached, and space on the bottom with a built-in heating pad on which to place an object… in other words, a perfect 3D printer frame!

Tropical Labs realized this, and turned the ordinary household appliance into a delta printer with three steppers for motion and another to feed the printing media. An Arduino Mega serves as the brains of the operation along with a popular RAMPS 1.4 shield. Read the rest of this entry »

Sort your M&Ms or Skittles with this ingenious machine

Arduino Team February 6, 2017

Inspired by a YouTube video of another candy sorter, Willem Pennings decided to build his own version.

After nearly eight months of work, he now has a device that can separate M&Ms or Skittles into their respective color dishes. Control is accomplished via a pair of Arduino Nano boards along with two EasyDrivers and an RGB sensor. These actuate a small servo for mixing the candies, and a stepper motor to properly position the candy tube.

Besides designing the controls for the machine, everything is modeled beautifully in the NX10 CAD package. The results, as seen in the video, look extremely polished–and it’s quite soothing to watch these candies drop into their little bowls in automated fashion!

You can find more details on Pennings’ project page and check out the video that inspired him here. Read the rest of this entry »

The Hunt is both a playful game and tasteful home decor

Arduino Team February 2, 2017

Carlos Rodriguez–who not only happens to be an Arduino team member but also a Masters student at Malmö University’s K3 school–has shared with us a project that he and a group of his interaction design classmates have created. 

For the outsider, The Hunt is an Arduino-based light board; a piece of decoration in a tasteful home. Its six carefully crafted boxes are sources of light that shine when attached to the board. But what’s hiding in plain sight is a whole new world. The intrinsic light and shadow patterns hide an exciting game of strategy, hunt, and kill. Read the rest of this entry »
