Make your own Operation-style board game with Arduino

Monday, July 24th, 2017

Usually, when you think of doing “surgery” on electronics, it’s to replace a component, or maybe modifying an appliance into something different. In this case, an Arduino Nano powers Hurry, Doctor!, an updated version of the board game classic Operation meant as a middle school STEM exercise.

This game, of which creator “TrevorB23” gives an extensive explanation in his Instructables write-up, features a LEGO minifigure with cutouts inside that house obstructions such as a “mental block” and “funny bone.” As with the original, the objective is to remove these foreign bodies without touching the sides, constructed here with conductive aluminum foil tape in order to signal the Nano.

Binge-watch and burn calories with the Arduino-powered Cycflix

Thursday, July 13th, 2017

As entertaining as watching Netflix may be, you’re not burning a lot of calories while binging on your favorite shows. In order to do both at the same time, hacker “Roboro” modded a stationary exercise bike to stop streaming if he’s not maintaining his fitness goals.

Bicycle speed is derived from the signal that’s normally sent to the built-in display. He uses an Arduino Nano to hijack the square wave, and sends this info to the streaming computer serially via USB. (more…)

Synth Bike 3.0 produces tunes with 12 Arduino Nanos

Monday, June 26th, 2017

After building a bicycle that could travel across town while making music, Sam Battle now taken things in a different direction. Synth Bike 3.0, which will be on display at the Science Center Dublin until September, is set up on a training fixture so that you can pedal it indoors rain or shine. This version also features a simplified control panel on the handlebars, allowing it to be played by anyone at a tempo controlled by the rear wheel’s speed.

Battle’s YouTube channel is named “LOOK MUM NO COMPUTER” however, this apparently doesn’t count microcontrollers. Hidden in the externally clean-looking handlebar groove box is a total of 12 Arduino Nano boards, along with a maze of wiring, strip circuit boards, frequency central PCBs, a SparkFun WAV trigger, and some other electronics. There’s even built-in speakers on the sides to output the created sounds.

Be sure to check out Synth Bike 3.0’s New Atlas write-up for more info on the project. (more…)

Face tracking with Arduino and Android

Tuesday, June 20th, 2017

Computer vision has traditionally relied on an assortment of rather involved components. On the other hand, everything you need to do this complicated task is readily available on an Android phone. The clever setup seen in the video here uses a smartphone to capture and process images, then send out a signal over Bluetooth to tell which way the device needs to be adjusted in order to focus on a nearby face.

An HC-05 Bluetooth module receives this signal and passes it to two servo motors via an Arduino Nano, moving the phone left/right and up/down.

You can find the Arduino code for this project on CircuitDigest, and the Android Processing code can be downloaded there as a compressed folder. (more…)

Arduino-controlled frame makes objects move in slow motion

Monday, June 19th, 2017

Though time may be relative, unless you’re planning on doing a lot of space travel, slowing things down in real life is “notoriously” difficult. On the other hand, with carefully-coordinated vibrations and lighting, the “sLOMO” device is able to make objects such as a feather or plant appear to move in slow motion with the naked eye.

Inspired by Jeff Lieberman’s Slow Dance Frame, this project is made out of a readily available IKEA Ribba frame, and the object inside vibrates using an electromagnet. An Arduino Nano controls this magnet and pulses a double-row LED strip, in order to make the item appear to slow down, or even distort itself into multiple overlapping images.


A Paris-inspired, Arduino-powered binary clock

Tuesday, June 6th, 2017

The La Fabrique DIY team has been working on a unique clock modeled after buildings seen along the Seine River in Paris. The “City Clock” is different from the others in that instead of a dial or decimal numbers, windows light up in a binary format, displaying the time in a binary sequence.

Electronics-wise, the clock can be made with an Arduino Uno, involving a fairly simple circuit with individual LEDs and resistors, as seen on this Imgur set. Also shown there is the Kickstarter version of the circuit, which amounts to a sort of gigantic shield that an Arduino Nano is plugged into.

With the City Clock, you calculate the time by adding every digit vertically. The first floor equals one, second equals two, third equals four, and the top equals eight. Using this system, it’s possible to create every digit from zero to nine by adding one number to another. (more…)

Computer gesture control via webcam and Arduino

Wednesday, May 31st, 2017

While touchscreens are nice, wouldn’t it be even better if you could simply wave your hand to your computer to get it to do what you want? That’s the idea behind this Iron Man-inspired gesture control device by B. Aswinth Raj.

The DIY system uses an Arduino Nano mounted to a disposable glove, along with hall effect sensors, a magnet attached to the thumb, and a Bluetooth module. This smart glove uses the finger-mounted sensors as left and right mouse buttons, and has a blue circle in the middle of the palm that the computer can track via a webcam and a Processing sketch to generate a cursor position.

Turn your door into an ‘alien portal’ using Arduino

Monday, May 15th, 2017

As YouTuber Evan Kale puts it, his set is was kind of boring. He decided to spruce things up by turning his ordinary door into an “alien portal,” lining it with a strip of RGB LEDs. Though this may not be the first time you’ve seen this type of lighting in action, he directs our attention to a few interesting details about using them in typical Kale style.

One interesting note comes around the 4:50 mark, where he points out his portal is controlled using Hue Saturation Lightness (HSL) via a potentiometer instead of RGB. This keeps the glowing effect consistent, while allowing color adjustment.

For this project, he employed an Arduino Nano, which looks like a great choice since it needs a limited amount of I/O. Using this tiny board, the entire control package can fit into his small 3D-printed enclosure. (more…)

Enhance your keyboard with the SlideBar

Friday, April 28th, 2017

Using a keyboard and mouse usually gets the job done, but if you want to navigate around a website or video, the process could be a little more efficient. It may not be a big deal to reach over and use your mouse and scroll wheel, but if you had this control on your keyboard, that tiny bit of time savings could add up over the thousands of times you do this.

For this purpose, Imgur user “Electricrelay” added a motorized force feedback slider to his keyboard using an Arduino Nano for control. This easily customizable device can scroll through pages, or switch between open browser tabs or programs. It can also act as a mechanical display, shaking for notifications, or sliding with keystrokes like an old-school typewriter. The Maker even created a plugin for timeline scrubbing in Adobe Premiere.

DIY panoramic thermal imaging

Wednesday, April 19th, 2017

Using an Arduino Nano and two rotary stages, this Maker hacked together a panoramic thermal imaging camera.

After ordering and finally receiving a thermopile (infrared thermometer) in the mail, the author of this project set to work to construct his own scanning thermometer. This type of setup acts like an IR camera, but instead of taking one instantaneous picture, it stores thermal data points that are then resolved into a coherent image.

Though the panoramic results can be fantastic, since the thermometer has to be rotated to each point individually via stepper motors on the rotary stages, a single image capture can take over an hour. (more…)
