Une rencontre pour le matériel scientifique open source. « Malgré les progrès technologiques, de nombreuses innovations scientifiques ne se concrétisent pas faute de matériel abordable et personnalisable, explique François Grey, professeur à l’Université de Genève et coordinateur de Citizen Cyberlab, un partenariat entre le CERN, l’Institut des Nations Unies pour la formation et la recherche (UNITAR), et l’Université de Genève – qui a co-organisé l’atelier GOSH!

Une rencontre pour le matériel scientifique open source

2016. « Cette pénurie de matériel scientifique accessible est particulièrement gênante pour les groupes scientifiques d’initiative citoyenne ou les organisations humanitaires qui ne disposent pas des mêmes moyens qu’un institut correctement financé. » Accéder librement au matériel scientifique permettrait en effet de limiter les coûts liés à l’instrumentation et d’élargir le cercle des utilisateurs, tout en facilitant la réutilisation et l'adaptabilité.

Australian scientists use soybean oil to create graphene

Graphene, a strong carbon material, is just one atom wide and conducts electricity better than copper. It was discovered at the University of Manchester in 2004, winning its inventors a Nobel Prize in 2010. Now researchers say they can make graphene with soybean oil, potentially making it more commercially viable. Michigan Technological University - Academia.edu.

Increasingly, this consolidation stems from an understanding that big-banner issues—such as climate change—are not the root causes of our present global predicament. There is a growing and collective view that issues such as this are actually symptoms of a much more vicious, seemingly insurmountable condition: our addiction to economic, consumption, and population growth in a world of finite resources. Explicit cookie consent. TAKE a cardboard disc and punch two holes in it, close to, and on either side of, its centre.

Thread a piece of string through each hole. Now, pull on each end of the strings and the disc will spin frenetically—first in one direction as the strings wind around each other, and then in the other, as they unwind.

Follow me on Twitter: @SteveSchuler20 and right here on Hackaday: KRA5H My original LaserOscope was featured on Hackaday.

Ethan Zonca, author of the article wrote the following about my LaserOscope: "If you’ve ever used an old-school analog oscilloscope (an experience everyone should have!) You probably noticed that the trace is simply drawn by a beam that scans across the CRT at a constant rate, creating a straight line when there’s no signal. The input signal simply affects the y-component of the beam, deflecting it into the shape of your waveform. CD/DVD based immunoassay - Wikipedia. Illustration of the basic componenets of a CD/DVD based immunoassay, which includes the disk (grey), a probe (green), gold nanoparticle (red), analyte (yellow), and silver particle (blue) A compact disk/digital versatile disk (CD/DVD) based immunoassay is a biochemical analytical test which determines the concentration of a compound by performing the test on a standard CD/DVD surface.

CD/DVD based immunoassay - Wikipedia

Samples are bound to the surface of the CD or DVD in a microarray format, and an antibody binds to the compound of interest. The CD/DVD based assays are read using standard CD/DVD readers. The technique using CDs/DVDs is cheaper than many comparable techniques.[1] Principle[edit] CDs and DVDs have a polycarbonate surface and metal reflective layer which allow for storage and retrieval of information. Applications[edit] The technique has a wide range of applications. The SkyLight - design for global health & science education by Tess & Andy. Kickstarter Collections Projects We Love Saved.

Open source hardware has the potential to revolutionise the way we build scientific instruments; with the advent of readily available 3D printers, mechanical designs can now be shared, improved, and replicated faster and more easily than ever before.

Abstract The introduction of affordable, consumer-oriented 3-D printers is a milestone in the current “maker movement,” which has been heralded as the next industrial revolution.

PLOS Biology: Open Labware: 3-D Printing Your Own Lab Equipment

Combined with free and open sharing of detailed design blueprints and accessible development tools, rapid prototypes of complex products can now be assembled in one’s own garage—a game-changer reminiscent of the early days of personal computing. At the same time, 3-D printing has also allowed the scientific and engineering community to build the “little things” that help a lab get up and running much faster and easier than ever before.

Welcome to the hackaday.io project page for the ramanPi! The ramanPi is a raman spectrometer that I decided to build back in April of 2014 because I needed one for another project and could not afford the tens of thousands of dollars a commercial product costs...and there are no DIY or open source systems in existence until now.

I knew nothing about spectroscopy, let alone raman spectroscopy back then and everything here documents my learning process towards my goal.....A fully functional, and fairly high resolution raman spectrometer. When I started this project, I had wildly different ideas about how I was going to achieve my goal. The project logs begin very early in my design process and document how I changed my approach and what led to the form it is taking now.

In the process of designing this system, and participating in TheHackadayPrize, I have learned a great deal.. #LOWCOST - #LED - A Simple, Low-Cost Double Beam Spectrophotometer for Colorimetric Detection of Nitrite in Seawater. 5–30 , but higher deviations elsewhere.

To do science, scientists need money—and usually a lot of it because specialized equipment and tools don’t come cheap.

That means researchers often have to spend a significant amount of time pursuing funds from government agencies and private entities. But the era of open-source software and cheap hardware, including 3-D printers, is making it easier for them to quickly test innovative ideas and make their own research tools.

#Hackers - Article - Why Neuroscience Needs Hackers. #LOWCOST - #i3D - Flypi - cheap microscope/experimental setup. Scientists need to have the proper tools to perform experiments and test their ideas. These tools are expensive, because they normally use cutting edge technology and are produced in "small" quantities by only a handful of companies. This ends up restricting who and where research is being done, which aggravates the situation in a lot of places where simple research could bring a lot of improvement to society.
