Automating a bubble blaster with Arduino Micro

Friday, September 18th, 2015

Thomas Renck is a coder and a maker. He went to Disneyland, saw a bunch of little kids having fun with bubble guns and realized that a bubble blaster is a sure way to measurably improve joy and happiness in life.

Back home, it took only two hours to create and add-on to automate the bubble blaster using a 3d printer, Arduino Micro and a servo: (more…)

A spider quadrobot built with Prusa and Arduino Pro Mini

Monday, September 14th, 2015


It takes 14 steps, a Prusa i3 3D printer and a lot of soldering to build Spider Robot v3.0, a quad robot running on Arduino Pro Mini.  That’s what told us  RegisHsu, a maker who shared his project’s tutorial on Instructables and the 3d printable files on Thingiverse.

It took 12 months of work to build the robot and it reached the fourth generation of  design, that you can explore on his blog  if you are interested in its history: (more…)

A DIY smartwatch designed by a kid for kids

Tuesday, September 8th, 2015


Omkar is a special 8 years old who created a wearable device called O Watch: an Arduino Zero-based smartwatch kit for kids. The project, recently kickstarted, allows young people to learn programming, 3D printing and a bit of craft while making their own smartwatch and customizing it. The kit will be released with a series of learning tools including a kid-friendly website with easy tutorials, examples and a community to share creations. (more…)

Building a giant Iron Man suit you can actually wear!

Thursday, July 16th, 2015


If you are a fan of cosplay, props and hand built creations you can’t miss the work of  James Bruton. Based in Uk he’s got a personal project YouTube channel with a new video every week describing his work in details. At the end of June he posted the 34th “episode” of the project started nearly a year ago about  building an Iron Man Hulkbuster giant suit you can actually wear! (more…)

An open hardware quartz crystal microbalance

Monday, March 23rd, 2015


Marco Mauro is a physicist currently employed as Scientific Coordinator at Novaetech, the first Spin-off Company of the National Institute for Astrophysics (INAF) in Italy. He shared with us all the info about a project he’s been working on  and based on Arduino Micro.

OpenQCM is a fully open source scientific microbalance capable of weighing mass deposition down to 1 billionth of gram: (more…)

Open Source 3D Printed Rocket Engine controlled by Arduino

Friday, February 27th, 2015


Fubar Hackerspace (New Jersey) member Graham has been working on an open source liquid fuel rocket engine with regenerative cooling and precise flow control built on Arduino Uno.  In order to test it he’s also built a cool rig for testing propellant flow control: (more…)

A tutorial about avoiding warping with Arduino Materia 101

Wednesday, February 11th, 2015


Some of you may have experienced that when you start to print a cube or box-shaped objects they can easily warp on the corners. The reason for this is the change of volume that plastic goes through when cooling down: it shrinks when becoming cooler. Even if PLA, the corn-based plastic we use on the Arduino Materia 101, shrinks much less than ABS, it can become a problem when printing things that require a high level of precision. (more…)

Now you can 3d print lego- compatible LED bricks

Wednesday, February 4th, 2015


The 3d printing tutorial Kristoffer, our 3d specialist, prepared this week is not part of the ongoing LEGO power functions compatible series but makes you still play around modding the famous bricks to add some cool light effects.


If you follow the 8 easy steps you’ll be able to print bricks with Arduino Materia 101 that can include addressable LED’s in your models. As in the previous tutorials, he modelled it using FreeCAD, but the way he did it should be applicable to just about any CAD-software or 3d modelling software.

Notice that in the last step of the tutorial you can also download the perfect settings to obtain good prints out of small pieces!


Check the previous tutorials on 3d printing with Material 101

Interested in getting in touch and showing your experiments? Join Kristoffer on the Arduino forum dedicated to Materia 101 and give us your feedback.

Circular Knitic and the power of doers in open source

Tuesday, February 3rd, 2015


Circular Knitic is an open hardware project created for DOERS, an exhibition curated by Arduino co-founder David Cuartielles, which takes place at Etopia Center for Art & Technology in Zaragoza, Spain.

It consists of an exhibition and a series of presentations, workshops and seminars focusing on the world of open creation, invention and personal fabrication. It aims to unveil a variety of extraordinary creations, ideas that are transforming the world, but mostly show visitors a group of people: “the DOERS, constantly looking for new projects that surprise us”.

During a period of eight months, 5 knitting machines will be knitting slowly and produce enough tubulars so that the ceiling of the art centre will be covered with knitted scarves.

Using digital fabrication and maker tools like 3D printing, laser cutting, makerbeam, and Arduino Uno— Knitic duo designed a replicable circular knitting machine. It’s not the first time they experiment on knitting techniques. A couple of years ago I interviewed them on this blog for their previous project focused on giving a new brain to old knitting machines using Arduino Due. (more…)

Design a LEGO- compatible servo holder and print it with Materia 101

Tuesday, January 27th, 2015


This week we are presenting you a new tutorial on 3d printing of Lego-compatible pieces with Materia 101. Kristoffer designed a brick with the parametric 3d modeler FreeCAD that can hold a small servo. Following the 10-step instructions  you can easily add wheels to robots built in LEGO and  use specific servos with different sizes. (more…)
