[Thomas Renck] recently picked up a 1000mW wireless video transmitter that he ultimately planned to mount in an RC plane. Before he strapped it on a plane to potentially kiss it goodbye for good, he wanted to play with it a while to see what it was capable of.
After a friend helped him determine the camera’s maximum range (about 1900 feet on open ground), he thought it would be fun to strap it on his nitro R/C truck. That didn’t work out so well due to some vibration issues, so he constructed a makeshift R/C car from the shipping box the camera arrived in, along with some other odds and ends.
As you can see in the video below, the propeller-driven “Boxmobile” zips along quite nicely. The video feed from the camera is pretty impressive too, allowing him to easily guide the car while it’s well out of sight.
At nearly $350, the self-proclaimed “ghetto-bot” is certainly not cheap, though we hear body repairs are a piece of cake!
Reports say that it can hit a top speed of 40 mph, but it seems that the fun is relatively short-lived, as the drone runs out of juice after about 8 minutes. While it is flying, the drone appears to be incredibly agile and fairly easy to control. The built-in camera isn’t top end, but it looks more than sufficient for general surveillance use.
While we love quadrocopters and all of the cool acrobatics they pull off, there’s something awesome about a drone that can hit the ground at speed, roll, and take off again without incurring any serious damage.
Anyone care to start work on a civilian prototype with a longer battery life?
This deathstar like ball is actually an autonomous surveillance camera. [Basil] wrote in to tell us about it. The body is custom designed for the project, then 3d printed. It can be dropped anywhere, as it is battery powered for up to a month, and communicates via cellar networks. It checks an email folder once an hour and responds to any requests with a snapshot of what is going on. In the video, which you can see after the break, he gets an immediate response. You can download the sourcecode as well as the files for the enclosure here.
If you wanted to reduce costs, that case could be done away with, but we suspect it helps with some moderate weather conditioning. We would also love to see a version that rotated around that equator on command for better pictures. Great job [Basil].
The students at the University of Oklahoma have put together a robot that will surely join the other drones in our future robot overlord regime. This autonomous vehicle was produced to replace human security patrols which can be both boring and dangerous. Intent on delivering surveillance to most locations, an all terrain vehicle was used as the base. It can navigate by itself through an obstacle avoidance system and communicate video and audio wirelessly. After the break we’ll take a look at the systems that make this work.

[randy] from F.A.T. tested the theory that infrared LEDs can actually hide you from the prying eyes of surveillance cameras. We’ve previously covered camouflage, IR, and other suggestions for eluding the cameras, but haven’t taken to sewing stuff onto our clothes yet. [randy] lined his hoodie with high-intensity infrared LEDs, hoping to create a halo effect that would hide his head, and tested his results. Unfortunately, his efforts were unsuccessful. He tested many many different combinations and we’re confident in his conclusion that it would be very hard to make this work.
The British military held a competition to find the newest batch of robotic surveillance drones. The article mentions that they compete in a mockup village, but sadly we don’t get to see any of the action. We strongly recommend watching the video so you can see some of the robots. There is an interesting helicopter concept that has angled props for better stability and lateral motion, but more importantly you get to see the little guy pictured above. He very well could be Wall-E’s great grandfather. Though his constant buzzing around during the interviews is slightly annoying, his little camera mount looking all around is instantly endearing. If he doesn’t win this contest, he may have a shot at the [crabfu] challenge.
This project has two demonstrations on their site. The first is dubbed the RTS-2 (Racial Targeting System). This system is essentially a camera which follows faces and is able to analyze and interpret the person’s race. The second is SOLA. This system is able to quickly scan someone and calculate their body mass index then publish this information to the web. Both systems achieve their goal by blatantly pointing out a line in which more surveillance does not equate to more security. They also show the wealth of personal data that can be obtained about a person by a simple camera.

Imagine our chagrin when we first laid eyes on this “laser surveillance defeater.” It’s supposedly built to the security requirements of federal agencies. We don’t believe most government issue devices have exposed circuit boards or 9V batteries dangling from them. Laser surveillance works by bouncing the beam off of a room’s window. People speaking in the room cause the window to vibrate, which modulates the reflected laser beam. This device looks like it’s just a piezo buzzer meant to vibrate in vocal ranges. A quick search didn’t turn up any DIY projects, but it looks simple enough. Shomer-Tec would love you to purchase one for every window at $69 each. A small price to pay when you’re taking on people willing to spend $20.
