Ever wondered what happens to old electrical cables?” A cable recycling machine cuts, strips, and separates copper or aluminum from insulation with high precision. Using vibration and air separation, it recovers valuable metals with minimal waste—turning discarded cables into reusable resources. Efficient, eco-friendly, and built for a sustainable future.

More tests. It's not possible to make the squishy surface for a full character with this method, but it's promising to see and fun to play around on!

How I built an Anime.js-style site with Claude 👇 • Ask Claude to plan a minimal interactive website with smooth motion • Install Anime.js → "npm i animejs" • Use Claude to generate timelines, staggered text, and hover animations • Add smooth SVG, scroll, and cursor interactions with Anime.js • Keep UI minimal so motion becomes the focus • Use easing + timing to make animations feel fluid and premium Save this 🚀

Repairing Underground Cables. NO Road Damage At numerous locations within Brookefields Layout, we have installed ducts and chambers to access underground cables and valves. Last Monday was the most recent cable fault. Where typically the road is hacked out and a crater left behind, here we simply un-weld the duct lid. When the underground cable is mended, we re-weld the lid. No road damage. Minimal traffic stoppage. Aside from allowing access, the duct, made of structural steel, protects 8-10 cable joints from hammering by ongoing traffic, and has reduced cable faults from once per month to once a year. A reminder that this duct was built with locally sourced money (Rs. 10 lakhs), and its design was provided by a local structural engineer. Local engineering talent. Local funding. Local execution. Local problem-solving.

made my first fired alumina print! lightcell energy 🔆 maybe i’ll call it a “lattice flame tokamak” 😉 this is where the flame occurs, held in place like a smoke ring. it’s supposed to be where the hot air and fuel mix, with channels pointing inward along a torus. the flame rolls around mixing fuel air and salt, like a rolling vortex, like a smoke ring. i constructed the geometry like this, it’s a triply-periodic minimal surface (TPMS). this divides a cylinder into two interlaced volumes with minimal material and the maximal surface area. it’s a “Schwartz-Diamond” type minimal surface with a bias, in cylindrical coordinates. the TPMS divides a space into two interlaced volumes. if you delete the material dividing these volumes then this is where the fuel and flames with mix and the reaction will take place. in addition, on average the channels will be pointed in along the torus throughout, canceling momentum and holding on to a recirculation vortex, there a flame will remain lit and where sodium can mix in via salt conducted in via wall surface tension, like a wick, and evaporation. the TPMS curves in all dimensions, so it is quite resistant to thermal stresses, can relieve stain along any of its curves. and it has thin walls so it can easily diffuse gases during debinding and sintering. had a small collapse in the center (probably a singularity in the model, cylindrical coordinates) but fired it anyway and it sintered beautifully! i used the latest version of Hyperganic hydesign for the geometry and a Formlabs Form 4 in Alumina 4N to do the printing. 💁🏻‍♀️☸️

GSTAR: Gaussian Surface Tracking and Reconstruction Contributions: • A new framework for tracking and reconstructing dynamic scenes, combining 3D Gaussians and meshes to effectively manage changes in topology. • A method for Gaussian unbinding and surface re-meshing, allowing for the generation of new surfaces as topologies evolve. • A method for handling large or fast deformations of surfaces between frames using scene flow warping. Abstract (excerpt): However, tracking dynamic surfaces with 3D Gaussians remains challenging due to complex topology changes, such as surfaces appearing, disappearing, or splitting. To address these challenges, we propose GSTAR, a novel method that achieves photo-realistic rendering, accurate surface reconstruction, and reliable 3D tracking for general dynamic scenes with changing topology. Given multi-view captures as input, GSTAR binds Gaussians to mesh faces to represent dynamic objects. For surfaces with consistent topology, GSTAR maintains the mesh topology and tracks the meshes using Gaussians.

Math. A rare peek from within a "Gyroid," a fascinating minimal surface in geometry that separates space into two oppositely congruent labyrinths of passages. By Andrea Belloni, Water flowing | anbello.eth | anbello.tez, Used with permission. This infinitely extending "labyrinth" surface divides all of space into two identical, intertwined, mirror-image passages: without ever intersecting itself. Discovered by mathematician Alan Schoen in 1970, it's a triply periodic minimal surface (zero mean curvature everywhere, like a soap film), with no straight lines or mirror symmetry. It can be approximated by the surprisingly simple equation: sin(x)cos(y) + sin(y)cos(z) + sin(z)cos(x) = 0. Nature loves it too: gyroid nanostructures in butterfly wing scales create iridescent colors through light interference, and similar forms appear in cell membranes, polymers, and even ketchup-like fluids. It's a superstar in materials science for lightweight, strong 3D-printed structures and photonic crystals.

Imagine slapping solar panels on your roof, shed, car, boat, or even a tent like a sticker! New paper-thin flexible panels stick to ANY surface (even curved), no drilling needed, bendable, and pump out up to ~85W per sq meter. Solar revolution incoming! ☀️🔋 Who's ready?

Updates to the Skateboard are on the way! It hasn't survived the best over the past couple years with VRC updates and a lot has changed. Tricks no longer spas out Have a grounder to rotate the board on a given surface Full VRC Fury compatibility- no more manual install!

I made it to the ball… Yes, I was horizontal again 40 mins later, feeling like 50 shades of shite with a heart rate of a hummingbird… and my carer in somewhat of a panic But I danced and laughed… I DANCED!!!

What looks like a server boiling underwater is actually one of the most advanced cooling technologies used in modern computing This demonstration showcases a two-phase immersion cooling system, a method increasingly explored for high-performance computing and AI infrastructure where traditional air cooling becomes less efficient. Instead of using fans to move heat away, server components are submerged in a specialized non-conductive dielectric fluid that safely surrounds the electronics without causing electrical short circuits. As processors generate heat, the liquid absorbs thermal energy and begins to boil directly at the component surface.

Another Art Trade with "HellShark1999". They wanted Roxanne Wolf in stocks getting licked and tickled by Glamrock Foxy. Been a long time since I've used the tongue as a tickling method, so it's nice to finally do it again. Thanks a lot my friend and please enjoy.

Did you know this machine can output up to 3000 kg of pressure? The brinell hardness test makes use of a 10 mm tungsten carbide ball to indent onto a surface, helping determine the hardness of a material. This can be primarily used for coarse structures like castings and forgings used in wellheads and blowup preventers. Having a higher hardness number would also mean the material would be suitable for conditions with constant abrasion, such as drill bits and pump liners, ensuring their longevity.
