Create the smart home gadget of the future with Alexa and Arduino

Tuesday, November 21st, 2017

We’re excited to announce a new challenge with Amazon Alexa and Hackster.io, which invites the Arduino community to design the smart home gadgets of the future.

Makers have already come up with exciting ways to integrate Alexa and Arduino into their projects, from talking teddy bears and singing animatronic fish, to voice-controlled blinds and holiday decorations, to robotic coffee machines and drink mixers. And now, we want to see what next-generation devices you can come up with. Personalized lighting? Room temperature automation? Security and doorbell systems? Pet toys and feeders?

Contest winners will be awarded with prizes that can help take their ideas from prototype to product through Dragon Innovation’s certification process, Kickstarter coaching sessions, cash, and more. (more…)

Antique grandfather clock retrofitted with Arduino control

Monday, November 20th, 2017

When you see a mechanical clock, you know on some level that it took a vast amount of expertise and craftsmanship to get working, but you might also assume that this could all be swapped out very easily with modern electronics. While this might be the case with a clock that only tells time, as David Henshaw shows with his project, once you add in extra features like a moon phase, date indicator, and chimes, things get complicated quickly.

Henshaw began by purchasing an 1847 vintage clock from England without the movement—the parts that actually it tell time. He then replaced the mechanical assembly normally found inside with stepper motors, sensors, an Arduino Uno, and a variety of other wires and bits. (more…)

Building an 8-step keyboard sequencer with Arduino

Monday, November 20th, 2017

Sequencers, as YouTuber “LOOK MUM NO COMPUTER” explains, are musical devices that go through a sequence of tones one by one. While this can be done quite simply with a 4017 counter chip, if you instead substitute in an Arduino board for the counter, you can make your gadget behave normally, go backwards, or even act as a sort of keyboard using input buttons.

This particular project employs a Nano for control, giving it a conveniently small form factor to fit inside your equipment. (more…)

DIY vending machine with Arduino

Friday, November 17th, 2017

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.

An excellent two-sided UV exposure box

Thursday, November 16th, 2017

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. (more…)

Creating a classroom quiz machine with Arduino

Tuesday, November 14th, 2017

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!

Star Wars fan builds an Arduino-powered R4-P17 replica

Monday, November 13th, 2017

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. (more…)

Desafío STEM + Arduino Podcast [Español]

Monday, November 13th, 2017

Con el fin de apoyar a los nuevos participantes del Desafío STEM 2017, Arduino y Telefónica se han unido para crear una serie de tres podcast, abiertos al público en general, conducidos por David Cuartielles.

Desafío STEM es un concurso interescolar que fomenta el desarrollo de competencias tecnológicas, creado por Telefónica Educación Digital para impulsar la implantación de nuevas formas de aprender a través de dinámicas motivadoras y fomentar las vocaciones STEM.

Durante los podcast se abordarán los siguientes temas:

  • Primer podcast: 15 de Noviembre
    Cómo crear proyectos creativos usando tecnología digital.
  • Segundo podcast: 22 de Noviembre
    Identificación de problemas técnicos en la creación de proyectos.
  • Tercer podcast: 5 de Diciembre
    Nuevos usos de tecnología en el aula.

La duración de los podcast será de una hora comenzando a las 19: 00 GMT+1. Podrán seguir la transmisión del podcast en: http://verkstad.cc/urler/desafiostem

David responderá durante el podcast preguntas de la audiencia que se envíen antes de los podcast. Para enviar las preguntas, seguir el link que se presenta a continuación y llenar el formulario: http://verkstad.cc/urler/desafio-preguntas. También se podrá participar en twitter con el hashtag #desafiostempreguntas.

Mini Strandbeest goes electric with Arduino

Thursday, November 9th, 2017

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. (more…)

Maker Faire Rome 2017: Call for Volunteers

Tuesday, November 7th, 2017

UPDATE: Thank you for all those who applied. Our call for volunteers is now closed. See you in Rome!

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.

Interested in helping out at our booth? Please fill out this questionnaire, and we’ll get back to you soon!

If you are underage, we will need your parents’ permission.
