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!

In the video below you can follow how he’s sorting out the arm mechatronics for the elbow, hand and cuff weapon with some 3D printing with Lulzbot and controlling the interaction with  Arduino Uno (electronic part starting around minute 10):

openQCM

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:

The sensing core of the microbalance is a piezoelectric quartz crystal oscillator. The deposition of a very tiny mass on the surface causes the variation in the quartz frequency. openQCM belongs to a new generation of innovative smart sensor which boast high resolution and ultra high mass sensitivity. The open source strategy made the creation of openQCM available at low cost which represents a bit fraction of the cost of similar scientific products.

openQCM was built keeping in mind the emergent principles of the open source hardware movement. The open source hardware gives people the freedom to control their technology through the open exchange of all the project features, 3D design, electronics and software. The open hardware potentiality is even greater when it comes to hardware for scientific applications.

openQCM is exactly something like that, the first open hardware quartz crystal microbalance with applications in a wide range of scientific fields, such as chemical and biological sensing, material science.

openQCM has an Arduino Micro board inside at heart. By hacking the timer counter of the AtMega32U4 Arduino microcontroller, it is possible to measure the quartz crystal frequency variations using the 16 Mhz microprocessor clock. openQCM team has designed an Arduino Micro shield with an embedded quartz crystal oscillator driver circuit and a temperature sensor. The output of the quartz crystal oscillator driver is fed to the Arduino Micro timer counter and the analog value of the temperature sensor is fed to the analog pin of the board. This configuration allow you measure the quartz crystal frequency with a resolution of 1 Hz, which roughly corresponds to a mass resolution of 700 pg over the entire quartz surface in air.

One of the major challenge of an open hardware project is that such devices require funding to prototype and manufacture. That’s why the openQCM team have selected the 3d printing technology to keep high quality and low cost. Using 3d printing to print out the prototypes via the SLS process from OS Formiga P100, P110, P395, and P730, the openQCM team created the device’s parts, which required a precision down to 60 µm.

The open source concept made openQCM publicly available so that anyone (scientists, technology enthusiast, makers, hobbyist …) can study, modify, and develop the hardware based on the original design. openQCM is now working and ready to win the heart of the scientific community and more.

Go and make one yourself!

Open Source 3D Printed Rocket Engine controlled by Arduino

Openrocket_Small

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

My project is building Open Source 3D Printed Rocket Engines with Arduino microcontrollers. As an individual interested in building liquid fueled rocket engines as a hobby I quickly realized there were almost no resources online or forums to share or learn from others. I decided to combine my interests in Software, hardware and open source projects to develop and build a functioning liquid fueled rocket engine. However, unlike most other projects it had to be open source and easily re-produced.

In order to ensure it was as open source as possible I used the Arduino Uno board and IDE to develop software to safely control the engine. To meet the easily reproducible requirement I decided that 3D printing was the right approach rather than labor/time intensive traditional machining.

The end result is an engine that can easily be reproduced or modified. This gives others interested in this hobby a starting point for best practices, safety, etc… so that future projects aren’t starting out from scratch.

All of my design files and software are on GitHub  and a detailed description of the write-up is on the FUBAR labs makerspace wiki 

Here’s the video of the testing of the 3D Printed GOX/Ethanol Injector:

A tutorial about avoiding warping with Arduino Materia 101

3D printing, 3DPrinting, arduino, Featured, materia 101, Materia101, tutorial, warping Commenti disabilitati su A tutorial about avoiding warping with Arduino Materia 101 

materia101tutorial9

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.

That’s why Kristoffer prepared a tutorial to solve the problem and shares some 3dprinting tricks with all of you. Follow the 5 steps of the tutorial and learn how to print without warping.
