Bluetooth is a great protocol. You can listen to music, transfer files, get on the internet, and more. A side effect of those many uses is that the specification is complicated and intended to cover many use cases. A team of researchers took a look at the Bluetooth specification, and discovered a problem they call […]
It seems a bit unfair to pile on a product that has already been roundly criticized for its security vulnerabilities. But when that product is a device that is ostensibly deployed to keep one’s family and belongings safe, it’s plenty fair. And when that device is an alarm system that can be defeated by a […]
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 […]

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, […]
