There is something inherently fascinating about tiny mechanical devices, especially when you’re used to seeing much larger versions. This is the case with [Penguin DIY]’s tiny centrifugal water pump built …read more Continue reading Turning a Pair of Syringes into a Tiny Water Pump
Whether you need to pump water out of your basement this spring, or just want to have fun shooting water around in the yard this summer, here’s a way to build a pump instead of buying one. This is a simple but ingenious build, and [NavinK30] did everything shy of machining his own hardware and making his own tools. Well, it looks as if he might have made that drill.
As you’ll see in his how-to after the break, this centrifugal pump is mostly acrylic, PVC, and fasteners. [Navin] cut two sides and a base for the paddles from acrylic, …read more
[Yoshihito Isogawa] almost never employs non-LEGO parts in his creations. He created an excellent centrifugal pump out of 100% LEGO. While mostly a curiosity, you can definitely get a sense of how the mechanics work.
A Power Functions motor turns a 6×6 round plate that appears to have 1×2 smooth plates jammed between the studs, and secured with a 4×4 round plate on the other end. He geared up the motor so the assembly is spun very quickly, with those smooth plates forcing the water through a Technic mounting hole in one of the bricks.
[Yoshihito] is known for his …read more
