Ah, the movies are an inspiration for so many projects. How many times have you seen a spy movie where a cutout in the pages of a book are hiding something? This was the inspiration which led [Paul] and his crew to try using a laser cutter to remove a handgun-shaped cutout from the pages. The fail began before the project even got started. The sacrificial book they had chosen was too thick to cut directly so they tore it in thirds for the cutting process.
The hijinks are portrayed well in the clip after the break. The infectious giggling as this first trace of the laser cuts the outline makes the video worth watching. As they try to go deeper, the success falls off rapidly. This makes for a great Fail of the Week discussion: Why can’t you cut through multiple layers of a book with a laser cutter? Is this merely a focal length issue that would be solved with a higher-end cutter or is there something else at play here. Let us know what you think by leaving a comment below.

This is the first in our series of videos meant to spread the hacking goodness far and wide on the net. As you can see, it is a pretty silly video, hopefully you enjoyed the humor. This wouldn’t be hackaday without an appropriate writeup though!
Initially the idea was to make this as a device that my boss could deploy from his Tesla Model S. Ultimately, we missed the release of SkyFall, so the whole 007 theme seemed a little flat. However, we did just happen to have a wonderful woman in the office that agreed to be an “overly attached girlfriend”. Here’s a link to the meme for those who are unfamiliar. Even though we made her look like a crazy person, she was a great sport about it (Thanks [Stephanie]!).
The Goal was to have a radio controlled device that would send live video and audio to someone and had the ability to plant a small GPS tracker on the undercarriage of a car.

Parabolic microphones are used to listen in from a distance. You see them on the sidelines of NFL football games, but they’re part of the standard issue in detective and spy novels. Now you can build your own parabolic microphone by following this example.
The one component that may be hard to find is the parabolic reflector. You cannot simply use a bowl or other curved object as the precise parabolic shape ensures that sound waves are reflected onto one finite focal point. For this build the reflector was obtained from an eBay seller. But the other parts are scavenged from easy to find sources. The microphone itself is an inexpensive element from Radioshack. It is mounted in the shell from a tweeter speaker, which helps to gather the sound if the element isn’t exactly aligned with the focal point. The setup also needs a preamplification system, which uses many components. Luckily there’s a schematic and other reference material linked in the write up.
You can also build a laser microphone which detects sound waves on a pane of glass.
[Thierry Legault] doesn’t just look up at the stars, the uses a motorized telescope base of his own making to track and photograph secret objects orbiting the earth. What do we mean by ‘secret objects’? Spy stuff, of course.
Last month he captured some video of the X-37B, an unmanned and secretive reusable spacecraft (read: spy shuttle) which is operated by the United States Air Force. That was back on the 21st of May but a few nights later he also saw the USA-186, an optical reconnaissance (Keyhole) satellite.
After trying to cope with manual tracking using the RC control seen above [Thierry] set out to upgrade his equipment. He ended up designing his own software package (and then released it as freeware) to automatically track the trajectory of orbiting objects. He uses a second telescope to locate the object, then dials it in with the bigger telescope. Once in frame, the software takes over.

Here’s a surprisly simple way to build yourself a laser-based listening device. It consists of two modules, a transmitter and a receiver. The transmitter is a set of lasers, one is visible red for aiming, and the other is infrared for measuring the vibration of a surface. Point the transmitter at the window of the room you want to listen in on and the laser can be reflected back to the receiver. The receiver module has a phototransistor to pick up the infrared laser light, and an LM386 audio amplifier to generate the audio signal sent to a pair of headphone. The need to be well-aligned which is easy enough using a pair of tripods. Check out the demo after the break.

Our initial view of the Spy Video TRAKR “App BUILDR” site had us believing this would be an internet-based code editor and compiler, similar to the mbed microcontroller development tools. Delving deeper into the available resources, we’re not entirely sure that’s an accurate assessment — TRAKR may well permit or even require offline development after all. Regardless of the final plan, in the interim we have sniffed out the early documentation, libraries and standalone C compiler and have beaten it into submission for your entertainment, in order to produce our first TRAKR hack!

Last Friday we looked at Wild Planet’s Spy Video TRAKR programmable RC vehicle mostly from an end user perspective. Much of our weekend was spent dismantling and photographing the device’s internal works, and poring over code and documentation, in order to better gauge the TRAKR’s true hackability. Our prior review included some erroneous speculation…we can clarify a number of details now, and forge ahead with entirely new erroneous speculation!
