This camera mod had to happen at sometime or another. Take cheap one-time use store bought digital cameras and mod them so you don't ever have to return them! This type of digital camera is improving in quality as digital parts continue to fall in price. So take a look if you want a digital camera but don't want to pay $100's.
This system has many different devices interfaced together all controlled by a central computer & program with a straight forward gui. The idea is to spice up this guys dorm room. He's made a decent write-up with pictures and videos, take a look.
We've seen high-altitude balloon projects before, here's another one! The project write-up has all the details of the computer system inside. Be sure to checkout the high-altitude aerial photos, awesome stuff.
The goal of the CMUcam project is to provide simple vision capabilities to small embedded systems in the form of an intelligent sensor. Since the project is open source, everything they've done is available for download and use in your own projects!
So what's with the tomato? This project was made to make a camera flash when it 'hears' a loud noise. In this case, a bb gun shooting a tomato! Check out the project write-up for a full description on the modification.
Moving to a true pyro design, we have the Stunning Camera. With some slight modifications to a single-use camera a stun-camera is born. Whenever someone tries to take a picture it gives them a mild shock (The video demonstration is pretty good).
CMOS cameras have recently become inexpensive for hobbyists and clean interfaces have been developed for them. This project uses an ATmega16 microcontroller to capture and output data from the camera. The complete report write up and source code is available for download so take a look!
Webcams are cool but night vision webcams are cooler. This project write up shows us exactly how easy it is to mod a generic webcam for night vision capability.
