Science

DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!

MAKE Volume 29: DIY Superhuman

MAKE Volume 29: DIY Superhuman

We have the technology (to quote The Six Million Dollar Man), but commercial tools for exploring, assisting, and augmenting our bodies really can approach a price tag of $6 million. Medical and assistive tech manufacturers must pay not just for R&D, but for expensive clinical trials, regulatory compliance, and liability — and doesn’t help with low pricing that these devices are typically paid for through insurance, rather than purchased directly. But many gadgets that restore people’s abilities or enable new “superpowers” are surprisingly easy to make, and for tiny fractions of the costs of off-the-shelf equivalents. MAKE 29, the “DIY Superhuman” issue, explains how.

The Tesla Valve: One Way Flow With No Moving Parts

The Tesla Valve: One Way Flow With No Moving Parts

Here’s yet another delightful mechanical curiosity from among Nikola Tesla’s nearly 300 known patents. Shown above is the sole drawing page from US patent #1,329,559, “Valvular Conduit,” issued 1920. You may have to stare at the upper section, for a moment, to figure out what’s going on: Flow from left to right, as illustrated, is against the valve’s bias—the stream is broken up and diverted in circular paths that return to interfere with each other. Flow from right to left, however, is not so impeded.

Solar Heater From Can Lids and Woven Plants

Solar Heater From Can Lids and Woven Plants

An interesting experiment from students in a course at Humboldt State University called Appropriate Technology Engineering 305. The parabolic form is essentially a large, shallow basket woven with fibers of locally-gathered Himalaya blackberry, which the students identify as an invasive species. In good weather, their dish could boil a jar of water in about two hours. I always like to see the clever thinking that can result from radical design constraints. [via No Tech Magazine]

Hamster Powered Submarine

Hamster Powered Submarine

This project dates back to 2009, but it’s entirely new to me: the HPS Hamstar is a hamster-powered submarine constructed out of a 3-liter bottle, a hamster wheel, and a few other household materials (with a total cost of $57). Its maiden voyage—documented above—was powered by Houdina, now in retirement after a single trip in the submersible.

LCD Projector Hacked Into a Medical Imaging System

LCD Projector Hacked Into a Medical Imaging System

I love stories like this, about how people are making use of off-the-shelf technologies to mimic the effects of more sophisticated and expensive scientific equipment. Yay DIY! The slow march of optical spectroscopies toward the clinic has been helped along by technologies borrowed from communications electronics. Those technologies are allowing optics researchers to build things […]

Cubelets Modular Robotics System

Cubelets Modular Robotics System

Cubelets are a robotic construction system from Modular Robotics. Using color coded cube modules, a maker can create a robot from snap together pieces that contain sensors, logic circuits, or “actions”. When attached together, the modules communicate via i/o built into the connector. Cubelets seem like they’d be the perfect introduction to robotics because you could easily get started creating robots without having to pick up a soldering iron.
