Many everyday objects make some noise as a side effect of their day job, so some of us hack would them into music instruments that can play a song or two. It’s fun, but it’s been done. YouTube channel [Device Orchestra] goes far beyond a device buzzing out a tune – they are full fledged […]
Direction finding has long been a pastime of the ham radio community. Fox hunts and other DF events have entertained many, as they swept their antennas hunting for a transmitter. As with rock and roll and flared pants, time changes all things, and [Corrosive] has been experimenting with a very modern way to go about […]
In Alaska, the impact of climate change is easy to see. Already the melting permafrost is shifting foundations and rocking roads. Hotter summers are also turning food caches from refrigerators into ovens. A permanent food cache. Via Wikipedia [rabbitcreek]’s friend builds food caches with kids as part of a program to teach them traditional native […]
Functional circuit sculptures have been gaining popularity with adventuring electronic artists who dare attempt the finicky art form of balancing structure and wire routing. [Kelly Heaton’s] sculptures however are on a whole other creative level. Not only does she use the circuits powering her works as part of their physical component, there are no controllers […]
As the 2019 mushroom foraging season approaches it’s timely to combine my thirst for knowledge about low level machine learning (ML) with a popular pastime that we enjoy here where I live. Just for the record, I’m not an expert on ML, and I’m simply inviting readers to follow me back down some rabbit holes […]
The concept behind non-line-of-sight (NLOS) imaging seems fairly easy to grasp: a laser bounces photons off a surface that illuminate objects that are within in sight of that surface, but not of the imaging equipment. The photons that are then reflected or refracted by the hidden object make their way back to the laser’s location, […]
Not so very long ago, orbital rockets simply didn’t get reused. After their propellants were expended on the journey to orbit, they petered out and fell back down into the ocean where they were obliterated on impact. Rockets were disposable because, as far as anyone could tell, building another one was cheaper and easier than […]
The Charliewatch by [Trammell Hudson] is one of those projects which is beautiful in both design and simplicity. After seeing [Travis Goodspeed]’s GoodWatch21 digital watch project based around a Texas Instruments MSP430-based SoC, [Trammell] decided that it’d be neat if it was more analog. This is accomplished using the CC430F5137IRGZR (a simpler member of the […]
