3D-Printed Hydraulic Pump, Braided Rope-Maker, and Halloween Props

Plus an emergency exit in your coffee table and a drone with propellers on a gimbal [Digi-Key is a proud sponsor of the 2021 Hackaday Prize]( [3602421454791242043.png] Wednesday, October 13, 2021 [Mac-o'-Lantern »]( A Keynote From LIGO, Plus Get Your Ticket and a Shirt! [Keith Thorne]( Keynote: Keith Thorne Did you hear the news? Keith Thorne is presenting a Keynote [at Hackaday Remoticon](. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is the most precise instrument humans have ever created, capable of measuring to a resolution of 1/10,000 the width of a proton in search of gravitational waves passing through our planet. Keith has worked on the project since 2008 and plans to share a ton of technical detail on bringing the project online and running the 4 km long instrument. [You don’t want to miss this so grab your ticket now!]( [Remoticon.2 Shirt]( But wait, there’s more news: this year we have shirts. Here’s how it works: [you only need 1 ticket]( to take part in the conference but you have two choices. If you opt for a $25 ticket you get one of these glorious conference shirts! This includes shipping in the US, international shipping is +$10 (sorry, this the reality of what we were able to set up). If you don’t want a shirt, no problem, just grab a free ticket so we can plan for how many people will show up. This is far from the only exciting Remoticon news, so sign up for one of those tickets and we’ll keep you in the loop. Highlights from the IO POPULAR BITS [project thumbnail]( [Flying, Rolling, Scooting Robot]( Here's an aircraft-of-a-different-color that manages to break all expected modes of locomotion. A pair of propellers are mounted on a spherical gimbal at the center of the skeletal frame. Each of six legs has a small wheel at the bottom. The propellers can roll it across a flat surface, or lift it into the air and travel in any direction. [project thumbnail]( [3D Printed Hydraulic Pump]( This hydraulic pump, which can be 3D printed, takes its inspiration from the hydraulic systems on Boston Dynamics robots. Unlike a peristaltic pump, the fluid travels directly through a double-helical gear system inside of a water-tight chamber in order to move the fluid within the hydraulic loop. [project thumbnail]( [Computing on a Bubble Display]( Our modern computers are so complex that users are kept far, far away from the actual functioning of the hardware inside. But this little Arduino-based emulator gets you up close and personal with the registers and how they work. For added awesomeness, a set of bubble displays read out data values, with plenty of push buttons included for input. Hack Chat LIVE CHAT WITH LEADING EXPERTS EVERY WEDNESDAY [Today: Resin Printing Hack Chat]( Andrew Sink will join us for [this week's Hack Chat](. It's hard to find a build these days that doesn't include a 3D-printed part, and that's testament to just how powerful the technology is. But while most of us are still squirting melted plastic for our 3D printing needs, stereolithography is getting cheaper and more accessible than ever. If there's a resin printer in your future, join us as Andrew Sink shares some of what he has learned lately.
