Complex Movements From Simple Inflatables, Thanks to Physics
Inflatable actuators that change shape based on injected pressure can be strong, but their big limitation is that they always deform in the same way. But by taking structural inspiration …read more Continue reading Complex Movements From Simple Inflatables, Thanks to Physics
You Can Put Toothpaste In the Tube (With Effort)
Old wives’ tales, folk knowledge, common sayings, and even cliches and idioms are often taken as givens since they form an often unnoticed part of our vocabulary and culture. There’s …read more Continue reading You Can Put Toothpaste In the Tube (With Effort)
Vacuum Dragster Uses Syringes For Propulsion
Atmospheric pressure is all around us, and capable of providing a great deal of force when used properly. As Otto Von Guericke demonstrated with his Magdeburg hemispheres over 350 years ago, simply removing air from a chamber to create a vacuum can have astounding results. More recently, [Tom Stanton] has …read more

Halloween Costume Turned Positive Pressure Suit
As a general rule, you probably shouldn’t be getting your Personal Protective Equipment (PPE) from the party store. But these are exceptional times, and rather than potentially depriving medical professionals the equipment they so desperately need on the front lines, the team at [Robots Everywhere] has been looking into improvised …read more

Pouring Creativity Into Musical Upcycling Of Plastic Bottles
Convenient and inexpensive, plastic beverage bottles are ubiquitous in modern society. Many of us have a collection of empties at home. We are encouraged to reduce, reuse, and recycle such plastic products and [Kaboom Percussion] playing Disney melodies on their Bottlephone 2.0 (video embedded below) showcases an outstanding melodic creation …read more

Exploring the Science Behind Dirty Air Filters
Obviously, if the air filters in your home HVAC system are dirty, you should change them. But exactly how dirty is dirty? [Tim Rightnour] had heard it said that if you didn’t change your filter every month or so, it could have a detrimental effect on the system’s energy …read more

Robot + Trumpet = Sad Trombone.mp3
[Uri Shaked] is really into Latin music. When his interest crescendoed, he bought a trumpet in order to make some energetic tunes of his own. His enthusiasm flagged a bit when he realized just how hard it is to get reliably trumpet-like sounds out of the thing, but he wasn’t about to give up altogether. Geekcon 2018 was approaching, so he thought, why not make a robot that can play the trumpet for me?
He scoured the internet and found that someone else had taken pains 20 years ago to imitate embouchure with a pair of latex lips (think rubber …read more
See the Fabulous Workmanship in this Smart Pressure Regulator
For many projects that require control of air pressure, the usual option is to hook up a pump, maybe with a motor controller to turn it on and off, and work with that. If one’s requirements can’t be filled by that level of equipment and control, then it’s time to look at commercial regulators. [Craig Watson] did exactly that, but found the results as disappointing as they were expensive. He found that commercial offerings — especially at low pressures — tended to leak air, occasionally reported incorrect pressures, and in general just weren’t very precise. Out of a sense of …read more

Putting More Tech Into More Hands: The Robin Hoods of Hackaday Prize
Many different projects started with the same thought: “That’s really expensive… I wonder if I could build my own for less.” Success is rewarded with satisfaction on top of the money saved, but true hacker heroes share their work so that others can build their own as well. We are happy to recognize such generosity with the Hackaday Prize [Robinhood] achievement.
Achievements are a new addition to our Hackaday Prize, running in parallel with our existing judging and rewards process. Achievements are a way for us to shower recognition and fame upon creators who demonstrate what we appreciate from our …read more
