Coming in hot from Cornell University, students [Amanda Huang], [Caroline Hohner], and [Rhea Goswami] bring a project that is guaranteed to tickle the funny bone of anyone in the under-40 set, and sadists of all ages: The Tamagochi Torture Chamber. He’s dead, Jim. In case you somehow missed it, Bandai’s Tamagochi is a genre-defining digital […]
Currently the typical way that crude oil is processed involves a fractional distillation column, in which heated crude oil is separated into the various hydrocarbon compounds using distinct boiling points. This requires the addition of significant thermal energy and is thus fairly energy intensive. A possible alternative has been proposed by [Tae Hoon Lee] et […]
Starting June 20th, any cordless phone, smartphone, or feature phone, as well as tablets (7 – 17.4″ screens) have to meet Ecodesign requirements. In addition there is now mandatory registration with the European Product Registry for Energy Labelling (EPREL). The only exception are phones and tablets with a flexible (rollable) main display, and tablets that […]
Here’s a great hack sent in to us from [Simon]. He uses an e-paper photo frame as a weather map! By now you are probably aware of e-paper technology, which is very low power tech for displaying images. E-paper only uses energy when it changes its display, it doesn’t draw power to maintain a picture […]
Before YouTube, you had to watch your educational videos on film. In the 1970s, if you studied radio, you might have seen the video from Universal Education and Visual Arts, titled Understanding Electronics Basic Radio Circuitry. The video’s been restored, and it appears on the [CHAP] YouTube channel. The video starts with a good history […]
I was watching Ben Krasnow making iron nitride permanent magnets and was struck by the fact that about half of the video was about making a magnetometer – a device for measuring and characterizing the magnet that he’d just made. This is really the difference between doing science and just messing around: if you want […]
We like scale models here, but how small can you shrink the very large? If you’re [Frans], it’s pretty small indeed: his Micro Tellurium fits the orbit of the Earth on top of an ordinary pencil. While you’ll often see models of Earth, Moon and Sun’s orbital relationship called “Orrery”, that’s word should technically be […]
To paraphrase an old joke: How do you know if someone is a Rust developer? Don’t worry, they’ll tell you. There is a move to put Rust everywhere, even in the Linux kernel. Not going fast enough for you? Then check out Asterinas — an effort to create a Linux-compatible kernel totally in Rust. The goal […]
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, […]
The last time we checked in with the ELIZA archeology project, they had unearthed the earliest known copy of the code for the infamous computer psychiatrist written in MAD-SLIP. After a lot of work, that version is now running again, and there were a number of interesting surprises. While chatbots are all the modern rage, […]
