Wrist thrusters let you fly through the water effortlessly

Friday, December 2nd, 2016

These small arm-mounted propeller units can carry a skin diver through the water with minimal effort.

YouTuber “PeterSripol” had only a week to prepare for his trip to Hawaii. Rather than purchase a set of fins or a snorkel, he instead hooked up two T100 thrusters that he had lying around to wrist straps. In his setup, these thrusters are controlled by a button interfaced with an Arduino that allows the user to select one of three power levels. (more…)

This wireless game controller looks like a rug

Thursday, December 1st, 2016

Cut in the shape of a gamepad, this controller sits on the floor for kids to enjoy!

Maker Jegatheesan Soundarapandian had gotten bored with computer games, and decided he, or rather his daughter, needed a new way to interact with the PC. What he came up with was a controller covered in cloth, with switches embedded between this covering and a wooden base.

Switches were made out of CDs and aluminum foil, which could be a good technique for others experimenting with unique interface devices. Control is accomplished with an Arduino Uno that communicates with a PC via a Bluetooth module. (more…)

Making beats on a tiny Arduino DJ controller

Wednesday, November 30th, 2016

Electronic music seems to be ripe for hacking, as a new device can be fun as well as quite useful. Imgur user “fatcookies” decided to create a small DJ controller using an Arduino Nano, six push buttons, three potentiometers, and four configurable LEDs. (more…)

This Arduino machine will judge how sick your ollies are

Tuesday, November 29th, 2016

In skateboarding, the ollie is a fundamental trick used to leap onto, over or off obstacles, or over gaps of unfriendly terrain such as grass or stairs. But how do you know just how sick your ollie actually was? Josh Sheldon has a solution.

The Maker has built a device that judges the sickness of your ollie and visualizes your score, rewarding the best ones with the chiming of a cowbell. Sheldon describes the project as something “like one of those hammer games at carnivals, but instead of trying to hit that thing with a hammer as hard as you can, the goal is to land the sickest ollie.”

The aptly named Sick Ollie Machine consists of two parts: a stand with LEDs and the skateboard itself. Underneath the board is an Arduino Uno, a 9V battery, and an accelerometer. The stand is equipped with another Arduino, a relay, and an RGB LED strip that goes up mast, as well as a solenoid on top. When the relay closes, the solenoid hits the bell. Both units also contain a wireless transmitter, allowing them to communicate with one another. (more…)

Turn an old payphone into a boombox for ’90s hits

Tuesday, November 29th, 2016

If you grew up in the ’90s and would love to play some of your favorite hit songs through something a bit more nostalgic than your smartphone, perhaps you can do what “digital alchemist” Fuzzy Wobble has done and transform an old-school payphone into a fully-functional boombox.

Fuzzy Wobble was able to get his hands on an inexpensive payphone and hacked it using an Arduino Mega, an Adafruit MP3 Maker Shield, a 20W amplifier, a 20W speaker, and some other components. The unique boombox is also equipped with a rangefinder that detects whenever someone walks by, triggering the phone to ring and enticing someone to answer the call. (more…)

QuadBot is a 3D-printable walking robot for everyone

Monday, November 28th, 2016

If you think building a walking robot is impossible, perhaps this little guy will change your mind!

With platforms like the various flavors of Arduino, robotics has become accessible for many more people. Walking robots, however, can still be challenging. Especially when it comes to electronics and programming, one has some fairly complicated mechanisms to figure out. Perhaps none is more frustrating than four-legged walkers, as they seem very stable, but that all changes when one foot is removed from the ground.

QuadBot aims to change this with an Arduino-compatible robot that, with clever cutouts for servo motors and plug-in headers on its main board, should be fairly easy to set up, yet capable of being expanded as needed. (more…)

An Arduino tachometer for your older vehicle

Monday, November 28th, 2016

Unlike most cars today, deepsyx’s old Opel Astra did not have a tachometer. So what’s a Maker to do? Build your own, of course.

To accomplish this, deepsyx used an Arduino Uno along with a few LEDs. The first LED turns on at 4000 RPM, while the others light up with every 500 RPM increment. At 5800 RPM, however, all the LEDs flash as a warning. There’s even a serial output of the RPM value, so logging real-time data can be a possible enhancement down the road.

I started by cutting a 5cm x 1.5cm piece of an old credit cart, drilled 4 holes in it, painted it black and glued 4 LED diodes to it. Then I soldered 220ohm resistors to each positive LED pin and used a common ground. I connected them to an Arduino via 5 x 30cm jumpers and hid the Arduino in a hole under the wheel. I connected the Arduino data pin via voltage divider to the signal pin of the coil and used an old phone charger to power the Arduino. In order to work, I shared the phone charger and Arduino’s grounds.

Intrigued? You can read more about this project on deepsyx’sGitHub page and over on Hackaday.

 

Harry Potter fans create a fully-functioning smart wand

Monday, November 28th, 2016

In the Harry Potter series, a Muggle is a person who lacks any sort of magical ability. Growing up reading these books, one can only imagine what it would be like to cast spells using a wand. Well, wonder no more as a group of NYC Muggles decided to build their own smart wand that can ‘magically’ control devices over Wi-Fi.

The 3D-printed wand is equipped with a voice recognition module that lets users cast spells of their own with a flick of the wrist, like ordering takeout from delivery.com, turning the lights on and off, as well as playing and silencing music.

A 3D-printed lunar phase clock for your nightstand

Wednesday, November 23rd, 2016

“Since there isn’t a supermoon everyday, make one for your bedside table!” This is exactly what G4lile0 set out to do using a 3D printer, an Arduino and some open-source tools.

The result was a moon phase clock consisting of a 3D-printed model and an LED strip to create the lunar phases. The lights are driven by an Arduino that precisely calculates which phase to show, as well as controls a 0.96″ OLED display revealing the date and time. Other electronics include an RTC module, a DTH11 sensor, a buzzer, and three push buttons.

The clock also features several modes, including an alarm, a wake-up light, a lamp, a thermometer, and a hygrometer. It can even help set the mood or start your next lunar rave with its relaxation and party-like special effects. (more…)
