An extremely well thought out marriage proposal with Arduino

Thursday, February 9th, 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

Thursday, February 9th, 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. (more…)

Teleknitting: TV-based string art

Wednesday, February 8th, 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.” (more…)

Start your day with Nerf target practice!

Tuesday, February 7th, 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! (more…)

Haptic game controller UnlimitedHand joins AtHeart!

Tuesday, February 7th, 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

Monday, February 6th, 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. (more…)

Sort your M&Ms or Skittles with this ingenious machine

Monday, February 6th, 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. (more…)

The Hunt is both a playful game and tasteful home decor

Thursday, February 2nd, 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. (more…)

The Rick and Morty Alarm will make sure you’re always on time

Wednesday, February 1st, 2017

Mike, CEO of the Useless Duck Company, recently got sidetracked playing computer games. After receiving a notification on his phone, he realized that he had lost track of the time and was late to a very important meeting. Being the Maker that he is, he decided to invent a system that would prevent this from happening again. Introducing the Rick and Morty Alarm.

Now Mike just has to enter how much time he has remaining (in hours, minutes and/or seconds), and he’ll receive an alert in the form of a Screaming Sun when it’s time to leave.

The alarm consists of a Windows Forms application that sends a serial signal to an Arduino Uno, triggering a stepper motor. He also designed and 3D-printed the mechanism that raises the TV show character’s cutout. Meanwhile, the loud yelling noise is played through his computer’s speakers.

Since this worked so well for his desktop, Mike says he created a mobile app to help him wake up in morning too. Check it out below!

Build your own MIDI accordion with Arduino

Wednesday, February 1st, 2017

If you want to play accordion via a MIDI interface, manufacturers such as Roland do make such a device. The downside is that they tend to be fairly expensive, as one would have to assume they are something of a specialty item.

Conversely, if you are able to get your hands on an accordion whose buttons and general movement work, but can’t actually produce good notes, you can build your own! This is just what developer and composer Brendan Vavra did, purchasing a broken instrument for $150 on eBay, then carefully disassembling the keys which were mapped to an Arduino Mega. (more…)
