This Arduino machine will sort your Skittles by color

Wednesday, July 20th, 2016

Do you just really hate yellow Skittles? Only love the red ones? Well, why waste your time sorting them out yourself when an automated machine can do it for you? As part of a recent tutorial, Dejan Nedelkovski has built what we calls the “Arduino Color Sorter” using a TCS3200 color sensor, two hobbyist servo motors, and an Arduino Nano. (more…)

The CALEIDUINO is a digital and sound reactive kaleidoscope

Tuesday, June 28th, 2016

The CALEIDUINO is an Arduino-based digital and sound reactive kaleidoscope, designed to serve as a toy, an art object, and a tool for teaching electronics and programming in a playful yet creative way.

At the heart of CALEIDUINO is a PCB for connecting an Arduino Nano, a TFT 1.8 “display, an analog 3-axis accelerometer GY-61, a piezoelectric, a switch, and a 9V battery–all of which are housed inside a hexagonal methacrylate case. Just like in any kaleidoscope, t three mirrors in triangular prism shape, while an accelerometer collects a user’s movement to generate the psychedelic graphics and sounds.

This funny robot pets your dog’s head and feeds them a treat

Thursday, June 23rd, 2016

While this recent project may look like something straight out of Simone Giertz’s notebook, it’s actually the brainchild of James Cochrane. The engineer, who admittedly loves building all sorts of crazy machines, has developed an apparatus he calls the IoT Robot People/Pet Affectionator.

As its name would suggest, the Affectionator is an Arduino Nano-driven device that automatically gives his dog T-Bone a pat on the head along with a spoon-fed treat at the touch of an arcade button. That’s not all, though. It even allows the pup to reciprocate by pressing his own button and sending over a token of his appreciation on a fork–which in Cochrane’s case is a gummy worm. (more…)

A DIY digital Arduino clock designed for and by teachers

Project-based lessons are a great way to introduce students to the world of electronics. Clearly Jenna Debois agrees, as she has built a DIY classroom clock based on an Arduino Nano. What’s even cooler is that it’s optimized for teachers!  (more…)

Dtto is a self-reconfigurable modular robot

Friday, June 10th, 2016

An entry in this year’s Hackaday Prize, Dtto is a snake-like robot designed to be modular and self-reconfigurable.

Inspired by Bruce Lee’s famous water quote, Dtto can transform into various shapes by changing the position and connection of its 3D-printed modules. As Hackaday points out, each section of Dtto is a double-hinged joint. When two come together, magnets help them align. A servo-controlled latch solidly docks the sections, which then work in unison. Impressively, it can connect and separate segments autonomously – without any human intervention. Creator Alberto believes the versatility of the bot will enable it to perform rescue missions, explore unknown environments, and operate in space. (more…)

Foxes Like Beacons explores alternative navigation systems

Friday, June 10th, 2016

Jochen Maria Weber’s Foxes Like Beacons is an exploratory project using open data of public radio stations with inexpensive, low-power signal detection in order to create an open positioning system. According to the designer:

Today’s satellite based GPS enable and augment uncountable everyday processes, ranging from logistics to fitness trackers and even intimate dating applications. These proprietary systems are mostly invisibly controlled and curated by governments, military and economic actors. Since GPS ubiquitously affect our interactions and experiences with our environment, economy and privacy, Foxes Like Beacons questions this present model, thus opening up space for speculations about alternative navigation systems and new models for interaction.

Open data about public radio stations, transceivers and open source signal detection can be used to calculate geo positions.

So, Weber developed three example devices based on the same technical structure using very low-power, open and off-the-shelf technology. This consists of an omnidirectional antenna, a 4.3″ TFT screen, a compass, gyroscope and barometric altitude sensor, a radio frequency tuner, a battery, an Arduino Nano (for signal processing), and a Rasperry Pi 2.

Control your DIY quadcopter with one hand

Friday, June 3rd, 2016

Back in 2014, Josef Holmner built his own DIY quadcopter with a flight time of 30 minutes. Impressively, he also developed a wearable controller that enabled him to maneuver his device through the air using just one hand.

As you can see in the video below, pitch and roll are dictated by the angle of his hand, yaw is handled by two push buttons in his palm, and throttle is achieved through the bending of his index finger. (more…)

Add biometric security to your next Arduino project

Thursday, June 2nd, 2016

If you’ve ever wanted to add biometric security features to your Arduino project, you’re in luck. That’s because Nick Koumaris of educ8s.tv has put together a quick tutorial on how to integrate a fingerprint sensor module with an Arduino Nano and a 1.44” color TFT display.

The fingerprint sensor module is small, nicely built, and it uses some advanced DSP (Digital Signal Processing) chips inside. The sensor works like this. It is an optical sensor, which means it analyzes the photo of a finger. It then renders the image, makes some calculations, finds the features of that finger and then searches in its memory for a fingerprint with the same characteristics. It can achieve all that in less than a second! This module can store up to 1,000 fingerprints in its memory and its false acceptance rate is less than 0.001% which makes it pretty secure!

As you can see in the video below, the project requires a valid fingerprint in order to unlock. If it recognizes the user, which in this case is Koumaris or his girlfriend, the fingerprint icon on the display turns green along with a kind greeting, e.g. “Welcome, Nick!”

Arduino MetroPhones will help keep you and your bag safe

Friday, May 27th, 2016

Walking the streets of a highly-populated city, or even a crowded event for that matter, comes with certain risks like pickpocketing. Mindful of this, Maker TVMiller has come up with a clever system to prevent bag thieves from unknowingly creeping up behind you. Called the “Arduino MetroPhones,” the device consists of a Nano, an ultrasonic sensor, a digital potentiometer, a coin-cell battery, and a few other components, all housed inside a 3D-printed case.

Draw images and words in falling water

Thursday, May 12th, 2016

The Base42 team, which is part of the hacking community Tecnoateneu Vilablareixhas created a stunning water curtain with the help of 3D printing and Arduino. The installation, currently on display at the Temps de Flors flower show in Girona, uses 128 3D-printed nozzles and 64 3D-printed valves to dispense water in floral patterns.

The water curtain employs four Arduino Nanos to control the valves, which work in pairs to draw the flowers, words or other images. Meanwhile, an Arduino Mega provides a Wi-Fi connection to issue commands. (more…)
