FANCY BEAR Targets Ukranian Howitzers

Posted on by

Just in case you’re one of the people out there who still doesn’t believe in “the cyber” — it appears that the Russian military served malicious cell-phone apps to the Ukrainian army that allowed them to track a particular artillery cannon.

The legitimate version of the Android app helped its operator use the 1960’s-era former Soviet howitzer. The trojanized version of this application did just the same, except it also phoned home to Russian military intelligence with its location. In addition to giving the Russian army valuable information about troop movements in general, it also led to the destruction of …read more

Computers For The Masses, Not The Classes

Posted on by

Retro is new again, and everywhere you look you’ll find films, documentaries, and TV shows cashing in on the nostalgia of their target audience. There is one inaccuracy you’ll find with this these shows: Apple computers are everywhere. This isn’t a historical truth – Commodore was everywhere, the C64 was the computer the nerds actually used, and to this day, the Commodore 64 is still the best-selling computer in history.

Commodore is gone, replaced with a superfund site, but the people who made the best computers in history are still around. At the 2016 Hackaday SuperConference, Bil Herd gave …read more

Pioneer AVIC Infotainment Units Hacked to Load Custom ROMs

Posted on by

Pioneer’s flagship AVIC line of in-car multimedia systems is compatible with both Android Auto and Apple Car Play, and offers all manner of multimedia features to the driver of today. What’s more, these in-dash wonders have spawned their own community, dedicated to hacking the units. The ultimate infotainment hack is to develop custom ROMs for these devices.

What this means is that owners of Pioneer AVIC units will eventually be able to flash a custom ROM onto their in-car device, allowing it to operate more like any other generic Android tablet on the market. The potential is there for installing …read more

This Old Mouse Keeps Track of Filament Usage

Posted on by

Keeping track of your 3D-printer filament use can be both eye-opening and depressing. Knowing exactly how much material goes into a project can help you make build-versus-buy decisions, but it can also prove gut-wrenching when you see how much you just spent on that failed print. Stock filament counters aren’t always very accurate, but you can roll your own filament counter from an old mouse.

[Bin Sun]’s build is based around an old ball-type PS/2 mouse, the kind with the nice optical encoders. Mice of this vintage are getting harder to come by these days, but chances are you’ve got …read more

The Joy of the ESP8266 and Blynk

Posted on by

I’ll admit it. I can be a little cheap. I also find it hard to pass up a bargain. So when I saw a robot kit at the local store that had been originally $125 marked down to $20, I had to bite. There was only one problem. After I got the thing home, I found they expected you to supply your own radio control transmitter and receiver.

Normally, that wouldn’t be a problem but lately… let’s just say a lot of my stuff is in storage and I didn’t have anything handy. I certainly didn’t want to go buy …read more

Raspberry Pi Radio Makes the Sweet Music of Bacteria

Posted on by

We’ve noticed a lot of musical groups are named after insects. Probably has something to do with the Beatles. (If you study that for a while you’ll spot the homophonic pun, and yes we know that the Crickets inspired the name.) There’s also Iron Butterfly, Adam Ant, and quite a few more. A recent art project by a Mexican team — Micro-ritmos — might inspire some musical groups to be named after bacteria.

The group used geobacter — a kind of bacteria found in soil — a Raspberry Pi, an Arduino, and a camera to build an interesting device. As …read more

Star Trek Phone Dock Might as Well Be From Picard’s Night Stand

Posted on by

Star Trek is often credited with helping spur the development of technologies we have today — the go-to example being cell phones. When a Star Trek April Fool’s product inspires a maker to build the real thing? Well, that seems par for the course. [MS3FGX] decided to make it so. The 3D printed Star Trek-themed phone dock acts as a Bluetooth speaker and white noise generator. The result is shown off in the video below and equals the special effects you expect to find on the silver screen.

Taking a few liberties from the product it’s based on — which …read more

Down the Rabbit Hole and Back Out Again: Serial Over Headphone Jack

Posted on by

[ttsiodras] tells an epic tale of getting a custom Debian kernel installed on an Asus MemoPAD (ME103K) tablet. Skipping to the end of the saga, he discovers what looks like serial data coming out on the headphone jack when the system boots, but the signal was so distorted that he couldn’t simply interpret it. The solution turns out to be attaching a level-converter chip.

A level converter is a non-inverting amplifier, usually with a Schmitt trigger for immunity against noise. In this case, it acts like a “binarizer” — outputting a high voltage when the input rises above a threshold, …read more
