This camera rig uses a Raspberry Pi to send a camera down fifty meters (mirror on RPi blog) in order to spy on sharks. We got really excited at first thinking that it might be using the camera module from the Raspberry Pi Foundation but that isn’t the case. Do keep reading though, there’s a lot of cool … Read the rest

Camera-based touchscreen input via an FPGA
May 20, 2013 By 5 Comments
[Chonggang Li] wrote in to share a link to the final project he and [Ran Hu] built for their embedded systems class. It’s called Piano Hero and uses an FPGA to implement a camera-based touch screen system.
All of the hardware used in the project is shown above. The monitor acts as the keyboard, using an image produced by … Read the rest
Bending and printing a curved camera dolly track
April 25, 2013 By 9 Comments
How lucky is [Transistor Man] that he found the materials for the tracks of this curved camera dolly just lying around the shop? The three rails making up the system are quarter-inch diameter and he was able to bend them by hand with the help of a 55 gallon drum. But to hold them in place so that the camera … Read the rest
Hacker sends this through the mail to record a video of the process

[Ruben van der Vleuten] wanted to get a look at the adventure a package experiences when shipped from one place to another. So he threw together this mishmash of components to record the experience. We certainly enjoyed watching the fast motion video found after the break. We wonder what the shipping agency thinks about this sort of thing?

We’re never really sure what to call these things. When we say “back up camera” it sounds distinctly like a redundancy system for when the primary camera fails to work. But it is used for when you move in reverse in an automobile. [Jeremy Blythe] built the distance sensing video system using a Raspberry Pi board as the brain.

DIY $6 serial cable for vintage Apple QuickTake cameras
March 26, 2013 By 15 Comments
Knowing he was a guy who liked electronics and taking things apart, one of [Erik]‘s friends sent him a vintage Apple QuickTake 100/150 digital camera as a bit of a joke. [Erik] enjoyed the gift, but since his friend hadn’t sent the necessary serial cable he really couldn’t do that much with it. He searched online only to discover the … Read the rest
LiFePO4 batteries work much better in a camera than NiMH
March 23, 2013 By 13 Comments
We agree with [Zapmaker] that Canon cameras chew through nickel metal hydride batteries. But we’re not going to use Alkaline because we think it’s wasteful. His solution is to use a battery that has a higher voltage rating. What you see here is a single lithium iron phosphate cell paired with a dummy cell to increase life between charges.
The … Read the rest
