Have you ever wanted a vending machine for snacks but didn’t know where to start? With an Arduino Mega, some motors, and an infrared sensor to detect coins, Dejan Nedelkovski decided to build his own using only hand tools.

The DIY vending machine’s structure is made out of MDF, and uses wires bent into helical shapes to twist items out of four storage spaces with continuous rotation servos. While they could just drop to the bottom, Nedelkovski added a little extra flair and constructed an elevator system powered by stepper motors to gently lower the chosen treat to the exit opening.

You can see the project in action below, and find more details in Nedelkovski’s write-up here.

If you want to make your own custom PCBs at home, one method is to paint a circuit board blank with photosensitive material, then expose the portion you don’t want to UV light using a printed transparency. After a process of etching and stripping, the correct traces are generated.

As seen here, in order to help with the UV process, GiorgiQ decided to create his own two-sided exposure box. It uses arrays of LEDs to produce the correct light, and an Arduino Nano for control.

The box itself is constructed out of MDF, white acrylic, and drawer slides to allow for easy insertion and extraction of the PCBs. It looks like an excellent tool, and his instructions would be a great place to start if you want to build your own!

Quiz games, where contestants try to “buzz” in and answer questions make for fun televised game shows, but they can also be great for making learning fun. In order to avoid paying several hundred dollars for an official quiz machine, Instructables user “arpruss” decided to build one for his school using an Arduino Mega.

The device uses a series of CAT-6 cables to connect individual arcade-style buttons to a central control unit with RJ45 connectors, allowing each contestant to buzz in with an answer. While not approved for official competition, the system can pick out button presses down to a precision of 50 microseconds or less and displaying the order on an LCD screen, reliably determining the fastest individual nearly all of the time!

The Certamen quiz team competition from the Junior Classical League involves quiz questions on Greek/Roman subjects. Individual contestants press buzzer buttons when they have an answer. The machine keeps track of the order in which buttons were pressed, subject to the team-lockout rule that once a player on a team presses a button, the other presses from that team don’t count. The machine we built was for three teams of four players each. Additionally, so that other school groups could use the machine as a standard quiz machine, there is an option to disregard teams and just keep track of button order.

Alejandro Clavijo, together with his father Jerónimo, spent two years building the first official fan-made model of the R4-P17 Star Wars droid. For those not familiar with this family of droids, R4-P17 was the robot companion to the young Obi-Wan Kenobi.

The replica is made of aluminum and wood, and runs on four Arduino boards. Impressively, the project has also been approved by Lucasfilm, the studio behind the saga, allowing Clavijo to bring it to official Star Wars events all over the world.

Clavijo sent us a bunch photos showing R4-P17’s construction, and more can be found over on its website. As you can imagine, the robot has been a big hit, already making several appearances on TV and in a number of blogs.

When not recreating Star Wars characters, Clavijo spends his days working as an engineer and has designed controls for “clean rooms” using Arduino Uno. You can see his design–made with CATIA–on Thingiverse.

Strandbeests, as originally conceived, are gigantic PVC creatures that walk across the sand under wind power. While building one is certainly an enormous undertaking, smaller models are available that let you experience this strange kinetic motion in a more approachable size. These are also normally propelled by moving air, but maker “ArduinoDeXXX” decided to take things further with a pair of DC motors and an Arduino Nano.

The project came together over five distinct iterations, starting off with the normal wind-driven version, then adding uncontrolled motors. After that, the Arduino was included for automation, and this was upgraded with an IR remote. Finally, ArduinoDeXXX integrated simple gesture sensing using an array of IR LEDs.

You can see the mini Strandbeest in action below, along with a few “bonus” improvements at the end.

Planning on attending Maker Faire Rome next month? We’re currently seeking volunteers to join our team during the event—staffing tables and displays, leading one-on-one workshops and demos, and providing technical assistance when necessary.

If you volunteer with us for one shift, you won’t leave empty-handed! You’ll receive a day pass; spend two days with us, and you’ll have a ticket for the entire weekend to explore the show. Water and snacks will be provided, of course, along with some Arduino goodies.

As outlined in this Circuit Digest write-up, with the right hardware, you can now control your computer using hand gestures. While interesting, this kind of technology can be a little expensive. But if you’d like to augment your notebook or laptop via simple gesture capabilities without breaking the bank, B. Aswinth Raj has your answer in the form of an Arduino Uno and two ultrasonic sensors.

His system places the two sensors at the top of a screen, which are read by the Uno. This data is then passed on to a Python program running on the host computer that allows for actions such as play/pause, fast-forward, and volume control while watching videos.

Given the nature of the setup, there’s no reason why more sensors or programming couldn’t be added for further control, perhaps as shortcut “keys” for your favorite design software package! You can read more about the project here, and see a demo of it below.

IT professional (and Arduino cap fan) John Milner had a minor problem. While his retro gaming setup could emulate a wide variety of systems and games, it was still missing the tactile feedback of the original controllers. Rather than “submit” to playing with only an Xbox 360 controller, he developed the Multijoy Retro Gaming System that can change gamepads with the turn of a knob using an Arduino Micro.

The resulting system lets him not only choose the original controller for each game, but if you want to mix things up and see how Super Mario Bros. would feel on a PlayStation 1, or even a Genesis controller, you can do that too! It also features shortcut buttons on the new console.

The Arduino presents itself as two joypads with native plug-and-play support for Microsoft Windows 7+ and Linux/RetroPie. The selector is simply a ring of LEDs with a potentiometer in the center, using the knob will move the lit LED to the desired controller pictured in that position, a simple system with an unexpected bonus of being a little retro in its appearance.

You can check it out in the video below, and see more of the project on his blog and on GitHub.

We’re excited to announce a new update to the Arduino Create web platform, which will enable fast and easy development and deployment of IoT applications with integrated cloud services on Linux-based devices.

What this means is that users will be able to program their Linux boards as if they were regular Arduinos. Multiple Arduino programs can run simultaneously on a Linux board and programs can communicate with each other leveraging the capabilities of the new open source Arduino Connector. 

Arduino Create Cloud now allows users to manage individual IoT devices, and configure them remotely and independently from where they are located. To further simplify the user journey, we’ve also developed a novel “out of the box” experience that will let anyone set up a new device from scratch via the cloud without any previous knowledge by following an intuitive web-based wizard

The initial release has been sponsored by Intel® and supports X86/X86_64 boards. As a reference implementation, a simplified user experience has been designed for the AAEON® UP² board, although other platforms are already supported by the Arduino Create Cloud platform, such as the Intel® NUC, Dell Wyse®, Gigabyte™ GB-BXT.

In the coming months, we plan to expand support for Linuxbased IoT devices running on other hardware architectures. Until then, you can find more information here and follow the tutorials below to help get you going:
