Adding threads to your 3D prints is a life-changing feature, but obviously there are a lot of trade-offs and considerations when deciding on how to go about this exactly. Between self-tapping screws, printed threads, heat inserts and a dozen other options it can be tough to decide what to go with. In a recent video […]
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 […]
[Project Farm] has a video in which a wide variety of AA cells are analyzed and compared in terms of capacity, internal resistance, ability to deliver voltage under load, and ability to perform in sub-freezing temperatures. Alkaline, lithium, and even some mature rechargeable cells with a couple thousand cycles under their belt were all compared. […]
You never know when inspiration is going to strike, and for [Ekaggrat Singh Kalsi], it struck while he was playing with one of his daughter’s hair ties. The result is a clock called “Bezicron” and it’s a fascinating study in mechanical ingenuity. The hair ties in question are simple objects, just a loose polymer coil […]
For one-off projects, adding a few integrated circuits to a PCB is not too big of a deal. The price of transistors is extremely low thanks to Moore and his laws, so we’re fairly free to throw chips around like peanuts. But for extremely space-constrained projects, huge production runs, or for engineering challenges, every bit […]
In the world of creation, few stories inspire as much as [Mrblindguardian], a 33-year-old who has been blind since the age of two, but refuses to let that hold him back. Using OpenSCAD and a 3D printer, [Mrblindguardian] designs and prints models independently, relying on speech software and touch to bring his ideas to life. […]
