Scientists from Cambridge University in the UK have developed a 3D printable microscope that can be used to test water. The device uses a Raspberry Pi and a tiny camera, and is currently being tested by British charity Oxfam, which could use it to speed up water testing in remote areas.
Tech-minded folk have long recognized the huge potential of ultra-compact, ultra-affordable computers like the Raspberry Pi. However, given that some of the most popular, talked-about, or “upvoted” examples of Pi projects tend to concern things like Gameboy emulation, you’d be forgiven for forgetting that such computers can be used to carry out truly important tasks.
Thankfully, a Cambridge University research team is currently working hard to serve up a slice of seriousness from the Raspberry Pi, having developed a 3D printable microscope that can be used to test water samples for bacteria. The device could be used to determine the safety of drinking water in remote areas.
The five researchers behind the WaterScope initiative are attempting to reduce the cost of water testing in the developing world, where many are at risk of catching waterborne diseases such as cholera, dysentery, and typhoid fever.
By creating a simple, open-source device that can be fabricated, asse...
