Open Microfluidics Instrumentation Playset

Posted on by

Micro-what? Microfluidics! It’s the field of dealing with tiny, tiny bits of fluids, and there are some very interesting applications in engineering, biology, and chemistry. [Martin Fischlechner], [Jonathan West], and [Klaus-Peter Zauner] are academic scientists who were working on microfluidics and made their own apparatus, initially because money was tight. Now they’ve stuck to the DIY approach because they can get custom machinery that simply doesn’t exist.

In addition to their collaboration, and to spread the ideas to other labs, they formed DropletKitchen to help advance the state of the art. And you, budding DIY biohacker, can reap the rewards. …read more

Riding Rollercoasters with 3D Printed Kidneys, Passing Stones

Posted on by

Citizen science isn’t limited to the nerd community. When medical professionals get a crazy idea, their options include filling out endless paperwork for human consent forms and grant applications, or hacking something together themselves. When [David Wartinger] noticed that far too many of his patients passed kidney stones while on vacation, riding rollercoasters, he had to test it out.

Without the benefit of his own kidney stones, he did the next best thing: 3D printed a model kidney, collected some urine, and tossed a few stones that he’d collected from patients into the trap. Then he and a colleague rode …read more

Hackaday Prize Entry: Profiling Underwater Light

Posted on by

The goal for the Citizen Science portion of the Hackaday Prize is to empower people to create their own devices to perform their own analyses For [Adam]’s project, he’s designing a device that measures the health of waterways simply by looking at the light availability through the water column. It’s called PULSE, the Profiling Underwater Light SEnsor, and is able to monitor changes that are caused by algal blooms, suspended sediments, or sewer runoff.

The design of PULSE is a small electronic depth charge that can be lowered into a water column from anything between a research vessel to a …read more

Highlights From Robotic Shipwreck Exploration

OpenROV shared the results of their June 2016 underwater expedition to locate and robotically explore the wreck of the S.S. Tahoe, currently sitting at a depth of 150m in Lake Tahoe. Back in 1940 the ship was intentionally scuttled in shallow water, but unexpectedly slid to a much deeper depth. OpenROV used a modified version of their new Trident design to dive all the way down to the wreck and take a good look at things, streaming it over the internet in the process.

We previously covered the DIY research vessel that was designed and created as a floating base …read more

Hackaday Prize Entry: An MRI Machine

Posted on by

Magnetic resonance imaging devices are one of the most fantastically incredible machines humans have ever built. They’re capable of producing three-dimensional images of living tissue by flipping protons around with a magnetic field. Ninety percent of the population doesn’t know what that sentence means, yet you can find an MRI machine inside nearly any reasonably equipped hospital in America.

For his Hackaday Prize entry, [Peter Jansen] is building a magnetic resonance imager, capable of producing the same type of images you’d get from the radiology department at a hospital. It’s going to be a desktop unit, capable of scanning fruit …read more
