We’ve always been interested in fluidic logic and, based on [soiboi’s] videos, he is too. His latest shows how to use silicone and a vacuum to build a multiplexed dot matrix display. This is a fascinating look at how you design with air instead of electrons. Just like a regular display, it isn’t efficient to […]
Silicone bakeware has become a staple in many kitchens due to its flexible, yet temperature-tolerant nature. New research from Canada shows it could be causing trouble for your liver and lungs, however. The siloxanes that make up silicone bakeware can target “the liver through oral exposure, as well as the liver and lungs through inhalation […]
[Prusa] have a number of announcements, and one of the more unusual ones is that liquid printing is coming to the Prusa XL. Specifically, printing in real, heat-resistant silicone (not a silicone-like plastic) is made possible thanks to special filament and a special toolhead. It’s the result of a partnership with Filament2, and the same […]
Have you ever finished up a bit of code and thought that typing “git push” in a terminal is just not a satisfying finish? So did [penumbriel], so he built a big red button he could smash instead. This is a very simple hack: an Arduino sits inside a 3D-printed case that holds a big, […]
For most of us, mirrors are something we buy instead of build. However, [Unnecessary Automation] wanted to craft mirrors of his own for a custom telescope build. As it turns out, producing optically-useful mirrors is not exactly easy. For the telescope build in question, [Unnecessary Automation] needed a concave mirror. Trying to get that sort […]
They might call it Levity, but there’s nothing funny about Rapid Liquid Print’s new silicone 3D printer. It has to be seen to be believed, and luckily [3D Printing Nerd] gives us lots of beauty shots in this short video, embedded below. Smooth, and fast. This bladder took 51 minutes according to the RLP website. […]
Capacitive touch buttons are a great way to turn just about any (non-conductive) surface into a button, but people generally dislike the lack of tactile feedback. [KontinuumLab] apparently agreed and decided to experiment a bit with ways to make such buttons more springy. You can check out the results of those experiments in the video […]
There are a number of ways to give a robotic actuator a sense of touch, but the AnySkin project aims to make it an overall more reliable and practical process. The idea is twofold: create modular grippy “skins” that can be slipped onto actuators, and separate the sensing electronics from the skins themselves. The whole […]
While it’s the ideal choice for mass production, injection molding is simply no good for prototyping. The molds are expensive and time-consuming make, so unless you’ve got the funding to burn tens of thousands of dollars on producing new ones each time you make a tweak to your design, they’re the kind of thing you […]
