Had some spare time today so this is what I built. A #Tesla #turbine #levitating on #neodymium #magnets
Check out these other videos of the awesome stuff I’ve been working on.
I built a car wheel out of epoxy

Spinning chemicals for faster reactions
Cardiff University scientists have devised a new way of making reactions up to 70 times faster by using state-of-the-art equipment to spin chemicals around.
They found that efficient mixing within a chemical reaction could be achieved by spinning chemicals and catalysts around in a small tube, causing the reactions to happen much quicker.
The new findings could have a profound influence on the way that chemicals are made in a wide variety of industries, from drug development to agriculture and fragrances.
Self Fuelled Transformable Liquid Metal Machine
Synthetic self-fuelled motors, which can spontaneously convert chemical energy into mechanical activity to induce autonomous locomotion, are excellent candidates for making self-powered machines, detectors/sensors, and novel robots. The present lab (Zhang et al. in Adv Mater 27:2648–2655, 2004 [1]). discovered an extraordinary self-propulsion mechanism of synthetic motors based on liquid metal objects. Such motors could swim in a circular Petri dish or different structured channels containing aqueous solution with a pretty high velocity on the order of centimeters per second, and surprisingly long lifetime lasting for more than one hour without any assistance of external energy. The soft material liquid metal enables the motors to self-deform, which makes them highly adaptable for accomplishing tough missions in special environment. Interestingly, the motors work just like biomimetic mollusk since they closely resemble the nature by “eating” aluminum as “food”, and can change shape by closely conforming to the geometrical space it voyages in. From practical aspect, one can thus develop a self-powered pump based on the actuation of the liquid metal enabled motor. Further, such pump can also be conceived to work as a cooler. Apart from different geometrical channels, several dominating factors, including the volume of the motor, the amount of aluminum, the property of the solution and the material of the substrate etc., have been disclosed to influence the performance of the autonomous locomotion evidently. This artificial mollusk system suggests an exciting platform for molding the liquid metal science to fundamentally advance the field of self-driven soft machine design, microfluidic systems, and eventually lead to the envisioned dynamically reconfigurable intelligent soft robots in the near future. In this chapter, the typical behaviors and fundamental phenomena of the self fuelled transformable liquid metal machines were illustrated.
Smart necklace will know you binged on Chunky Monkey
There you are wrist deep into a quart of Ben & Jerry’s Chunky Monkey, digging ever deeper. You can’t deny it. Your necklace is recording the ice-cream binge, which it will later dispatch to a coach or dietician.
The aim is not to induce guilt but rather answer the question: “How did you get here?”
Meet NeckSense, the first technology to precisely and passively record multiple eating behaviors. It can detect in the real world when people.
3D Printing is Revolutionizing the Chocolate Industry
Charles Goulding and Ryan Donley of R&D Tax Savers discuss 3D printing as it impacts chocolateering.
Chocolate has been around for millennia now, dating as far back as early 1750 B.C., presumably in the area of the Gulf Coast of Vera Cruz where cocoa beverages or chocolate drinks were used in ceremonies by pre-Olmec peoples. Evidence suggests cacao pods may have even been used in alcoholic beverages as early as 1400 B.C. Today, the cacao bean has evolved to encompass a $50 billion chocolate industry worldwide that consists of edible chocolate confections being brought to mass markets.
Researchers Create Shiny Rainbows of Nanotech Chocolate
While so many of us are working at home during the coronavirus pandemic, we do worry that serendipitous hallway conversations aren’t happening.
Last year, before the pandemic, it was one of those conversations that led researchers at ETH Zurich to develop a way of making chocolates shimmer with color—without any coloring agents or other additives.
The project, announced in December, involves what the scientists call “structural color”. The team indicated that it creates colors in a way similar to what a chameleon does—that is, using the structure of its skin to scatter a particular wavelength of light. The researchers have yet to release details, but Alissa M. Fitzgerald, founder of MEMS product development firm AMFitzgerald, has a pretty good guess.
Tiny Weed-Killing Robots Could Make Pesticides Obsolete
Clint Brauer’s farm outside of Cheney, Kansas, could be described as Old MacDonald’s Farm plus robots. Along with 5,500 square feet of vegetable-growing greenhouses, classes teaching local families to grow their food, a herd of 105 sheep, and Warren G—a banana-eating llama named after the rapper—is a fleet of ten, 140-pound, battery-operated robots.
Brauer, the co-founder of Greenfield Robotics, grew up a farm kid. He left for the big city tech and digital world, but eventually made his way back to the family farm. Now, it’s the R&D headquarters for the Greenfield Robotics team, plus a working farm.
When Brauer returned to his agricultural roots, he did so with a purpose: to prove that food could be grown without harmful chemicals and by embracing soil- and planet-friendly practices. He did just that, becoming one of the premier farmers growing vegetables in Kansas without pesticides, selling to local markets, grocery store chains, and chefs.
Age-related heart disease linked to gut bacteria metabolite
New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.
High blood levels of trimethylamine-N-Oxide (TMAO), a metabolic byproduct of digestion, have been strongly linked to negative cardiovascular health. When one eats red meat, eggs or other animal proteins, certain types of gut bacteria feed on chemicals in those foods and produce TMA, or trimethylamine, which is then turned into TMAO in the liver.
A number of studies have linked TMAO to heart disease, however, until now it hasn’t been clear exactly how this metabolite causes cardiovascular damage. A robust new study, published in the journal Hypertension, is offering one of the first thorough mechanistic investigations illustrating how TMAO damages the cardiovascular system.
