Using an Arduino, along with a stepper motor and ball bearings, YouTuber GreatScott! has created a very smooth camera slider.

Time-lapse sequences can be interesting on their own, but if you can add motion to the camera, this adds a really neat element. To give a little extra flair to his video production, GreatScott! built his own motorized slider using stainless steel and aluminum parts. Movement is accomplished via an Arduino Nano controlling a stepper motor, and ball bearings are used to keep the shots smooth. You can see the results and process in the two-part video sequence below.

In this project, I will show you how I repurposed two old camera tripods in order to create a motorized camera slider. The mechanical system consist mostly of aluminium and stainless steel which makes the slider sturdy and pretty decent looking. The electrical system consists of an Arduino Nano with LCD, rotary encoder, limit switches and stepper motor.

My Goal was to come up with a design where all the speciality parts could be ordered  for under $20US.

The bill of matirels (BOM) looks like this:

2 ea 9g CR Servos

2 ea Wheels for the Servos

1 ea 4xAAA battery box with switch

1 ea SR-04 ultrasonic range sensor  

1 ea Arduino IDE compatable ATTINY85 based controller board.  Such as a Digispark, Iteaduino or any one of the similar devices.

The MR-808 robotic drum machine looks like a gigantic Roland synthesizer, but plays with real instruments!

The Roland TR-808 was released in 1981 and was meant to replace a human drummer for practice purposes, but was instead used to produce music itself, helping to birth the electronic, techno, and hip hop genres. Moritz Simon Geist and the Sonic Robots collective, however, decided to turn this on its head, with a machine made to look like a gigantic ‘808, but containing real instruments.

With a variety of hardware, including an Arduino Uno and Mega, an audience can program the MR-808 using a tablet and get down to the grooves they create themselves!

In 2013 I [Geist] found Sonic Robots a loose group of friends, hackers, technicians and artists and we had the idea of reversing the concept of the ‘808 and putting the physical aspect back into this gorgeous drum machine. For the Installation MR-808 we began to replaced eleven sound with mechanical actuators like motors and solenoids, so that reals drums (snare, BD ..) could be played live.

You can read all about the device on the Sonic Robots page, as well as find more information on how it works here.

Spectroscopy is an incredible tool for chemical analysis–and now you can make your own Bluetooth-enabled device with an Arduino Pro Mini.

If you took advanced chemistry classes, you may have had the opportunity to work with a spectrometer. It probably seemed like a magical gadget, identifying the chemicals in a substance through its light characteristics unlike the experimental methods you previously had to use.

Using off-the-shelf components–including an Arduino, a Bluetooth module, an LED, optical filters, and a LiPo battery–housed inside a 3D-printed case, the WiSci aims to take this tool out of the lab, and into the “real world.” By following the instructions on its project page, you can build one for just under $250.

What’s really neat is that the portable spectrometer can even scan a fruit and then wirelessly send the data over to an accompanying Android app to tell you whether or not the fruit is ripe. (You can view its IEEE Spectrum article for a little more background on that!)

A spectrometer is a very powerful tool. By analysing intensity/wavelength pairs of the interacted EM radiation with the material under study, detailed information like its chemical composition, crystal structure and other elemental information can be extracted. It can also be used for food analysis. For example, it can reveal adulteration in milk or oil and analyse toxins to understand causes of food poisoning to name a few uses.

A group of students from Farmington, Connecticut partnered with artist Balam Soto and master teachers Earl Procko and Jim Corrigan to create a community-based sculpture project that allows people to explore the sights, sounds and history of their town through new media.

The installation runs on Arduino Uno and XBee, and is comprised of two panels which act as viewing screens for multiple visual projections. Visitors can interact with the display and manipulate the images using 24 buttons placed on the physical map. Plus, they are encouraged to record and add their own stories and memories of Farmington to the ever-growing multimedia library.

Permanently exhibited in Farmington’s public library, the Farmington Map Project was also the opportunity to introduce the students to physical computing, digital fabrication, woodworking, Arduino programming, and to the potential that Makerspaces have to offer for bringing ideas to life.

The project was created with the support of an Arts in Education Mini-Grant, funded by the Connecticut State Department of Education, the Department of Economic and Community Development, the Connecticut Office of the Arts, and the Connecticut Association of Schools, Farmington High School’s Fine and Applied Arts.

Inspired by the traditional thermal printers, the PyroGraph is an experimental plotter that uses a soldering iron to burn images onto paper.

Created by the team of Bjørn Karmann, Lars Kaltenbach and Nicolas Armand, PyroGraph works by analyzing any picture and then converting it into dots that are scorched onto a piece of paper with a 450 °C tip. The time of contact between the iron and the paper determines the grayscale of the dot?—?the longer it presses against the paper, the darker the dots get.

The machine uses a paper roll (so the length of the printed piece can then be up to 100m) and a head moving on a fixed x-axis, controlled by servo motors and a custom software developed by the group of Copenhagen Institute of Interaction Design students.

But that’s not all. The PyroGraph will also listen to the ambient noise within its environment to make a connection between the space and the printer. The drawings will be distorted depending on the sound activity of the room in which it will be displayed.

From our Chairigami Maker Faire booth furniture to Google VR headsets, we’ve seen various use cases for cardboard. Added to that list is a robotic arm, courtesy of Uladz Mikula.

According to the Maker, the design can be replicated in two hours using Arduino and four servo motors. Aside from the electronics, the project also calls for a piece of hardboard for the base and three clips.

The arm, which Mikula calls “CARDBIRD,” can be controlled in one of two ways: either from a PC using a Processing program or remotely via an IR pult/receiver. Ready to build your own? Check over to its Instructables page!

While exploring new tangible interfaces, designer Martin Hertig wanted to do something a bit different. He chose to transform the zippers on a guitar bag into a fully-functional instrument. Rather than strum the strings of the guitar, he simply pulls the bag’s zippers to jam: one zip for playing notes or chords, another for changing the bar, and a third for the vibrato.

As Hertig explains, the case was converted into a MIDI controller using an Arduino and conductive thread stitched along the zipper, while a Raspberry Pi synthesizer hidden inside produces the guitar sounds.
