Making music with your muscles!

0
0
After being inspired by an Old Spice commercial where actor Terry Crews plays music with his muscles and EMG sensors, hacker Julio David Barriga decided to do the same thing using an Arduino.  While Crews’ setup involves an entire one-man band, Barriga’s system is greatly simplified, detecting the amplitude of the electrical signals emanating from […]

DoggoBot is an Arduino-controlled cardboard robotic pet

0
0
While building a walking robot especially with less than six legs can be quite a challenge, maker “Skill Mill NYC” decided to construct a quadruped robot named DoggoBot using cardboard for its body. Four micro high torque servos power the legs, which are able to move the robot around with the help of unpowered knee joints. […]

Teddy Ruxpin answers queries with Arduino and Google Assistant

0
0
If you have an unused Teddy Ruxpin lying around, you’re in luck. This hack from “Jayden17” turns the iconic ’80s toy from a fancy tape player into your own talking bear assistant! The build started out with obtaining one of these vintage bears and fixing up the internals, as well as equipping it with a new speaker. […]

A Flexible Arduino Prototype

0
0
We recently visited NextFlex, the flexible electronics manufacturing institute in Silicon Valley, where they developed a flexible prototype based on the Arduino Mini. Their mission is to make flexible electronics mainstream, opening up all kinds of new applications. How did you make the flexible Arduino prototype? Some of the equipment we use is familiar. For example, automated screen printers and […]

A DIY Automobile Black Box with Arduino Mega

0
0
If you’d like to monitor your driving habits, or perhaps keep them handy in the event of an accident, a “black box,” or more properly a “telematics” device is just what you’re looking for.  Monitoring driving habits can be interesting, but what if you’d like to make a telematics box yourself, giving you total control […]

These high school students built their own vending machine

0

If you’re a high school student and would appreciate a vending machine in class, what’s to be done? Most of the time the answer is “not much,” but Tustin High T-Tech students were able to get one—by building it themselves! In fact, this excellent device functioned both as a class project and as a fundraiser […]

This Arduino-controlled robot slithers like a snake

0
0
Would you like to create a robot that slithers from place to place like a snake? Well now you can, thanks to this bio-inspired design from Will Donaldson.  Donaldson’s project uses 10 metal gear servos to allow his robotic snake to curl its body back and forth, sliding along on small wheels that replace a real serpent’s […]

Pull small planes around with this Arduino Mega-based tug

0
0
While there are many ways to move an airplane on the ground, Anthony DiPilato decided to create a “tug” of his own.   The treaded device looks like a tiny tank, and when it slides under the aircraft’s front wheel it locks in place, allowing a 5,200-pound plane to be pulled around courtesy of the RC system’s […]

Arduino here, there, and at all the EDU faires!

Arduino All Over With the arrival of Spring, just prior to the ending of the academic year in Spain, teachers and education initiatives have been celebrating STEAM events all over the country. I personally attended RoboCampeones in Fuenlabrada, a small city outside Madrid, but there were a lot more: Robolot, FanTec, Cantabrobot, Granabot, ROByCAD, and even […]

Meme Weaver guides users through fabric creation

0
0
We all need to wear clothes, but where do they come from? If you answered “the mall,” then perhaps it’s time to play a couple rounds on the “Meme Weaver.”  As seen here, this project by the husband and wife team of David Heisserer and Danielle Everine prompts users to adjust levers correctly in order to […]

An Automated Paper Cutter

0
0
Are scissors and manual paper cutters not working for you? Well, “Mr Innovative” has the solution in the form of an Arduino-driven device that cuts paper to length automatically.  As you can see in the video below, a user simply inputs the length of paper and the number of strips needed via a series of […]

SmartCash can sort and give out change

0
0
If you run a small business where transactions are made, handling out coins is a necessary part of the job. While a cash register does the trick, perhaps you could try out the SmartCash device—a cylindrical electromechanical system running on an Arduino Mega—to help you count coins and make change. Aside from sorting coins, there’s the added […]

MESOMIX is an automated paint mixing machine

0
0
If you’re an artist who works with paint, getting your colors right is critical, and somewhat of an art form in itself. For those that need a little assistance, the MESOMIX paint mixing machine is here to help using four 3D-printed peristaltic pumps to pull the right amount of cyan, magenta, yellow, and black (or key) to […]

TerraDome is a Jurassic World-themed terrarium

0
0
If you need a warm place to keep your tropical plants, then look no further than the beautiful “TerraDome” from maker “MagicManu.” The device is equipped with an Arduino Mega that helps regulate the temperature inside its clear octagonal structure via a reptile heating pad, along with a fan salvaged from a PC power supply. […]

Earth Clock brilliantly tracks the sun’s light

0

While we understand that the Earth rotates to produce day and night, and tilts on its axis to vary the day’s length, how is the planet positioned in relation to the sun right now? Unless you’re well-attuned to our solar system’s rotational dance, this is difficult to visualize. To help with this, hacker “SimonRob” came […]

Control your GoPro wirelessly with an Arduino MKR1000

0
0
As Arduino boards have revolutionized what people can make at home, you might say that GoPros have done the same thing for portable cameras. Later generations of these devices even feature WiFi capabilities, so with the proper programming, Arduinos like the MKR1000 can be used for control! In this project write-up, maker Randy Sarafan (AKA […]

Robotic Connect Four lets you play remotely

0
0
In order to restore some tactile feeling to remotely-played board games, maker “lyudatan” created a pair of Arduino Uno-based Connect Four robots.  When a player makes a move by dropping a disc into a slot, this is recorded by an IR proximity sensor on the first board. The data is then transmitted via an Ethernet […]

An auto-curing chamber for SLA prints

0
0
If you have a 3D printer, it’s probably the fused deposition modeling (FDM) type that deposits melted material onto a bed, eventually building up whatever you had in mind. Stereolithography (SLA) printers, however, work in the opposite way using light to solidify liquid material, which is then pulled out of a vat.  While an interesting […]

Bucky Glow is an Arduino-controlled LED dodecahedron

0
0
After successfully building a gigantic geometric interactive light structure, Jonathan Bumstead decided to do things in a more approachable manner, creating a more a reasonably-sized dodecahedron controlled by an Arduino Nano. The device, named “Bucky Glow,” uses 11 RGB LEDs to light up each side with the exception of the bottom pentagon section. While it […]

Audio preamplifier with tiny OLED display and unique case

As spotted here, Sam Izdat decided to make a preamplifier for a friend who provides voice talent for audiobooks and the like. The primary audio circuitry for the build is provided by a purchased PCB based on the INA217 chip from TI, but from there things get a bit more interesting. To complete the project, […]
