"Another piece of my ongoing FPGA stereo-vision project. This board is, as the name suggests, a breakout board for Aptina’s excellent MT9V032 1/3″ VGA image sensor. The board’s main purpose in life is to connect the LVDS output of the MT9V032 sensor to my FMC-LPC to SATA adapter board, which would then route the LVDS data into one of Xilinx’s Spartan-6 FPGA development boards. Multiple camera boards would be connected to support stereo vision."

"I wanted my robot to be able to track object and follow them. The first thing I wanted to do is give the robot the ability to follow an object with its head camera. The head camera is mounted on a pan-tilt servo system, and hence is capable of moving left and right, up and down."

"PanoBot is a rudimentary panorama-taking device for any Canon camera running the CHDK firmware. This project was made back in ’08 so there are numerous projects that are much more full-featured than this implementation; nevertheless, I am making the code available for reference."

"The most straightforward approach to this would be to take apart an existing remote and fire its button with a microcontroller. However, that didn’t sound like much of a challenge, so instead the goal became to train the micro to output the signals itself."

"The circuit works great for dropping coins, marbles, fruits and the like into a glass of water, but the microphone pre-amplifier is just not sensitive enough to detect a single drop of water falling from a height, unless you hold the microphone really close. Am still working on a more sensitive version that should be able to do that."

"I got a new phone a couple of weeks ago: the Nokia Lumia 928. It has a great camera, so I decided to build a rig for panning and tilting it. The robot features two degrees of freedom that can be manipulated independently, is controlled through Bluetooth via an easy to use remote, and rotates the phone exactly around where the lens is located."

“How to control your camera shutter release from your Ipod (r) or other MP3 player. An ‘intervalometer’ is a device that remotely triggers the shutter in a DSLR camera at pre-defined intervals. This can be a very useful device for shooting time-lapse video or simply a sequence of shots at regular intervals without operator intervention.”

“Project Holodeck is a virtual reality platform built with consumer facing technology, DIY off-the-shelf components, cutting-edge custom software, and creatively integrated peripherals. The goal of Project Holodeck is to bring 360-degree 6-DOF full-body virtual reality out of the research lab and into a fun, accessible consumer gaming platform.”

“Last summer, I found myself with a few broken cameras on hand. Having lots of lenses to choose from, I decided to try to build a projector.”

“This is an IR remote control for Nikon cameras. It is compatible with the Nikon ML-L3 remote control…The circuit is extremely simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery. You could even omit the transistor and resistor, and connect the IR diode directly to the ATtiny13V, but that will limit the LED current and therefor the range.”
