[RyderCalmDown] was watching a road painting vehicle lay down fresh stripes on the road one day and started thinking about the mechanism that lets it paint stripes in such a …read more Continue reading Is This The World’s Largest Dot Matrix Printer?
While there are already garments which cool or warm their wearer via circulating liquids, those garments tend to be equipped with cumbersome, noisy pumps. An experimental new system, on the other hand, uses interwoven tubular fibers as pumps.Continue R… Continue reading Clothing with interwoven “fiber pumps” could warm or cool wearers
Let’s just clear something up right from the start with this one: there’s literally no reason to build your own tire inflator from scratch, especially when you can buy a …read more Continue reading Homebrew Tire Inflator Pushes the Limits of PVC Construction
When you’re maintaining a fish tank, it’s actually quite important to get all your basic chemistry right. Mismanage things, and you’ll kill all the helpful bacteria in the tank, or …read more Continue reading Fish Tank Dosing Pump Built Using Pi Pico
Researchers at Columbia University and New York Presbyterian have developed an implantable pump that can continuously deliver chemotherapy drugs directly into the brain to fight hard-to-treat cancer. In a phase 1b trial, patients were able to undergo t… Continue reading Implantable pump drip-feeds chemotherapy directly into brain tumors
Lobe pumps are perhaps most popularly known for their use in Rootes-type superchargers, but they can pump water, too. [Let’s Print] demonstrates this ably with a 3D-printed design that can …read more Continue reading 3D-Printed Lobe Pump Shifts Water Well
Kidneys perform a vital function in removing waste and toxins from the blood, but how exactly cells transport that fluid through the organs has remained a mystery. Now researchers at Johns Hopkins University have investigated the mechanical forces at w… Continue reading Previously unobserved pumping action of kidney cells discovered
The peristaltic pump is perhaps most well known for its ability to pump fluids without the pump mechanism coming into contact with the working fluid. This is key for food-safe …read more Continue reading Stout Peristaltic Pump Fabricated From Scratch
