Hackaday Links: January 22, 2017

What is a 1971 Ford Torino worth? It depends, but even a 2-door in terrible condition should fetch about $7 or $8k. What is a 1971 Ford Torino covered in 3D printed crap worth? $5500. This is the first ‘3D printed car’ on an auction block. It looks terrible and saying ‘Klaatu Varada Nikto’ unlocks the doors.

Old Apple IIs had a DB19 connector for external floppy drives. Some old macs, pre-PowerPC at least, also had a DB19 connector for external floppy drives. These drives are incompatible with each other for reasons. [Dandu] has a few old macs and …read more

Steve Collins: When Things Go Wrong In Space

Posted on by

[Steve Collins] is a regular around Hackaday. He’s brought homebrew LIDARs to our regular meetups, he’s given a talk on a lifetime’s worth of hacking, and he is the owner of the most immaculate Hackaday t-shirt we’ve ever seen.

For the 2016 Hackaday SuperConference,  [Steve] took a break from his day job of driving spacecraft around the Solar System. As you can imagine, NASA plans on things going wrong. How do you plan for that? [Steve] answers all your questions by telling you what happens when things go wrong in space.

Space is the worst possible place for hardware. Not …read more

Shmoocon 2017: The Ins And Outs Of Manufacturing And Selling Hardware

Posted on by

Every day, we see people building things. Sometimes, useful things. Very rarely, this thing becomes a product, but even then we don’t hear much about the ins and outs of manufacturing a bunch of these things or the economics of actually selling them. This past weekend at Shmoocon, [Conor Patrick] gave the crowd the inside scoop on selling a few hundred two factor authentication tokens. What started as a hobby is now a legitimate business, thanks to good engineering and abusing Amazon’s distribution program.

The product in question is the U2F Zero, an open source U2F token for two-factor authentication. …read more

Shmoocon 2017: Software Defined Radio for Terahertz Frequencies

Posted on by

Before Bluetooth, before the Internet of Things, and before network-connected everything, infrared was king. In the 90s, personal organizers, keyboards, Furbys, and critical infrastructure was built on infrared. Some of these devices are still around, hiding in plain sight. This means there’s a lot of opportunities for some very fun exploits. This was the focus of [Mike Ossmann] and [Dominic Spill]’s talk at this year’s Shmoocon, Exploring The Infrared World. What’s the hook? Using software-defined radio with terahertz frequencies.

Infrared communication hasn’t improved since the days of IrDA ports on laptops, and this means the hardware required to talk to …read more

Shmoocon 2017: Dig Out Your Old Brick Phone

Posted on by

The 90s were a wonderful time for portable communications devices. Cell phones had mass, real buttons, and thick batteries – everything you want in next year’s flagship phone. Unfortunately, Zach Morris’ phone hasn’t been able to find a tower for the last decade, but that doesn’t mean these phones are dead. This weekend at Shmoocon, [Brandon Creighton] brought these phones back to life. The Motorola DynaTAC lives again.

[Brandon] has a history of building ad-hoc cell phone networks. A few years ago, he was part of Ninja Tel, the group that set up their own cell phone network at DEF …read more

Raspberry Pi Launches Compute Module 3

Posted on by

The forgotten child of the Raspberry Pi family finally has an update. The Raspberry Pi Compute Module 3 has been launched.

The Pi 3 Compute Module was teased all the way back in July, and what we knew then is just about what we know now. The new Compute Module is based on the BCM2837 processor – the same as found in the Raspberry Pi 3 – running at 1.2 GHz with 1 gigabyte of RAM. The basic form factor SODIMM form factor remains the same between the old and new Compute Modules, although the new version is 1 mm …read more

What’s more expensive than a car and a less useful means of transportation? A 747 flight simulator built in a basement. There’s a project page where a few more details are revealed. There’s a 180 degree wrap-around screen for the main display, a glass cockpit, and the controls and gauges are ‘good enough’ to feel like the real thing. The simulator is running a highly customized version of FS9 (Microsoft’s flight sim from the year 2004).

For the last few years, Google has been experimenting with high altitude balloons delivering Internet to remote populations. This is Project Loon, and simply …read more

Shmoocon 2017: A Simple Tool For Reverse Engineering RF

Posted on by

Anyone can hack a radio, but that doesn’t mean it’s easy: there’s a lot of mechanics that go into formatting a signal before you can decode the ones and zeros.

At his Shmoocon talk, [Paul Clark] introduced a great new tool for RF Reverse Engineering. It’s called WaveConverter, and it is possibly the single most interesting tool we’ve seen in radio in a long time.

If you wanted to hack an RF system — read the data from a tire pressure monitor, a car’s key fob, a garage door opener, or a signal from a home security system’s sensor — …read more

Shmoocon 2017: So You Want To Hack RF

Posted on by

Far too much stuff is wireless these days. Home security systems have dozens of radios for door and window sensors, thermostats aren’t just a wire to the furnace anymore, and we are annoyed when we can’t start our cars from across a parking lot. This is a golden era for anyone who wants to hack RF. This year at Shmoocon, [Marc Newlin] and [Matt Knight] of Bastille Networks gave an overview of how to get into hacking RF. These are guys who know a few things about hacking RF; [Marc] is responsible for MouseJack and KeySniffer, and [Matt] reverse engineered …read more
