Electron Microscopes Are Awesome: Everything You Didn’t Know You Wanted to Know
Electron microscopes were once the turf of research laboratories that could foot the hefty bill of procuring and maintaining such equipment. But old models have been finding their way into the hands of eager individuals who are giving us an inside look at the rare equipment. Before you start scouring Craigslist, go on a crash course of what you need to know with Adam McComb’s Hacker’s Guide to Electron Microscopy. He presented the talk at the 2018 Hackaday Superconference and the recording was just published, you’ll find it below. …read more
Predicting Weather with the Internet of Cars
Follow this train of thought: cars have sensors, cars are in frequent use over large areas, cars are the ultimate distributed sensor network for weather conditions.
Many years ago, as I wasted yet another chunk of my life sitting in the linear parking lot that was my morning commute, I mused that there had to be a way to prevent this madness. I thought: What if there was a way for the cars to tell each other where slowdowns are? This was long before smartphones, so it would have to be done the hard way. I imagined that each vehicle …read more
Hackaday Podcast Ep6 – Reversing iPod Screens, Hot Isotopes, We <3 Parts, and Biometric Toiletseats
What’s the buzz in the hackersphere this week? Hackaday Editors Elliot Williams and Mike Szczys recap their favorite hacks and articles from the past seven days. In Episode Six we cover an incredible reverse engineering effort Mike Harrison put in with iPod nano replacement screens. We dip our toes in the radioactive world of deep-space power sources, spend some time adoring parts and partsmakers, and take a very high-brow look at toilet-seat technology. In our quickfire hacks we discuss coherent sound (think of it as akin to laminar flow, but for audio), minimal IDEs for embedded, hand-tools for metalwork, and …read more
In Space, No One Can Hear You Explode: The Byford Dolphin Incident
“It wouldn’t happen that way in real life.” One of the most annoying habits of people really into the “sci” of sci-fi is nitpicking scientific inaccuracies in movies. The truth is, some things just make movies better, even if they are wrong.
What would Star Wars be without the sounds of an epic battle in space where there should be no sound? But there are plenty of other examples where things are wrong and it would have been just as easy to get them right — the direction of space debris in the movie Gravity, for example. But what …read more
Hack My House: Garage Door Cryptography Meets Raspberry Pi
Today’s story is one of victory and defeat, of mystery and adventure… It’s time to automate the garage door. Connecting the garage door to the internet was a must on my list of smart home features. Our opener has internet connection capabilities built-in. As you might guess, I’m very skeptical of connecting a device to the internet when I have no control over the software running on it.
The garage door is controlled by a button hung on the garage wall. There is only a pair of wires, so a simple relay should be all that is needed to simulate …read more
