Ink stamps can be fun to make and use, and 3D printers are uniquely positioned to create quality stamps of all kinds with just a little care. As with most things, the devil is in the details and the best results will require some extra work. Luckily, [Prusa] has a blog post that goes through […]
A research project shows that it’s possible to create complex single-piece lenticular objects, or objects that have lenticular lenses built directly into them. The result is a thing whose appearance depends on the viewer’s viewpoint. The object in the image above, for example, is the same object from five different angles. What’s really neat is […]
Generally, the projects featured on Hackaday actually do something. We won’t go as far as to say they are practical creations, but they usually have some kind of function other than to sit there and blink. But what if just sitting still and blinking away randomly is precisely what you want a piece of hardware to […]
Here’s a design for a split-flap clock that doesn’t do it the usual way. Instead of the flaps showing numbers , Klapklok has a bit more in common with flip-dot displays. Klapklok updates every 2.5 minutes. It’s an art piece that uses custom-made split-flaps which flutter away to update the display as time passes. An […]
Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to levitate inside a rotating copper tube, so he cast a spherical copper cage to levitate a magnetic sphere. Metal casting is an […]
Most of us have made paper airplanes at one time or another, but rather than stopping at folded paper, [VirgileC] graduated to 3D printing them out of PLA. Then the obvious question is: can you cast one in cement? The answer is yes, you can, but note that the question was not: can a cement […]
Marble machines are a fun and challenging reason to do engineering for the sake of engineering. [Engineezy] adds some color to the theme, building a machine to create 16×16 marble images automatically. (Video embedded below.) The core problem was devising ways to sort, lift, place, and dump marbles in their correct positions without losing their […]
[3DPrintBunny] is someone who continually explores new techniques and designs in 3D printing, and her latest is one she calls “pause-and-attach”, which she demonstrates by printing a vase design with elements of the design splayed out onto the print bed. The splayed-out elements get peeled up and attached to the print during a pause. At […]
[Ben] may be 15 years old, but he’s got the knack for 3D printing and artistic mechanical design. When you see his 3D-printed mechanical jellyfish lamp, we think you’ll agree. Honestly, it is hardly fair to call it a lamp. It is really — as [Ben] points out — a kinetic sculpture. One of the […]
