If you have been listening to security now with Steve Gibson for a few years you probably heard about the portable dog killer (listen from 57:46). Not sure if Matt Meerian has listened to this Security Now episode but the Ultrasonic Dog and Cat Deterrent Project he sent in sure sounds similar to that project. Matt built this project to use on a bike to ward off dogs and
Check out the video above it demonstrates what a Horizontal Stabilization Camera System can do. You can see the build details over at Instructables. A camera mounted 8 feet behind the car sure gives you a cool perspective. This rig is being controlled by a huge servo and the actual arm that has the camera mounted to is has a large counterweight on it to balance it out. Not
 Most of the quadcopters we see look almost the same, you need to look at the specs to see what is different about them. Jose Julio sent in his Quadcopter that was made to look like a Formula1 Race Car, now there isn’t any mistaking it for another! The body looks great yet the construction seems to be nice and simple, Jose took some red coroplast plastic and cut
This GPS Dog Collar by Adafruit Tracks how far your Dog has Walked. This is great to make sure your dog is getting a healthy amount every day. It is based on a small microcontroller board, a GPS module and a cool OLED display. Becky Stern shows us how she put together the project in the video below. That ribbon material that is used to make the electronics look
 If you are like us you have a cat that roams the house and pushes the boundaries. When our current cat came home for the first time he was often seen sleeping in the middle of the table, chasing him off the tables for a week or so did the trick and now he knows that the tables are off limits. Very occasionally he still sneaks up on
So you thought that your camera gear was kick ass? Have a look at the rig that Pedro Guimaraes has put together. If a 3D RED camera system wasn’t enough he has linked in his steadicam onto a Segway so that he can drive around by simply leaning and effortlessly swing around the huge monstrosity of a camera to capture the optimal smooth shot. I can’t wait to see
Jeri shares some interesting build details of the C64 Bass Guitar. The brains of the system is a Spartan FPGA, I was surprized to see that the pickups were made using round disk piezo elements that were cut into rectangles. I didn’t think that a piezo element would work properly if it were cut like that. I guess they are much more robust that I had thought! If you
