Using a chicken as a steadicam

This has been circulating around the net for a bit. For those that haven’t seen it, let me just give you a quick rundown of what is happening. This guy strapped a camera to a chicken’s head. No really, that’s it. There’s some interesting science behind it though. He’s taking advantage of the Vestibulo-Ocular Reflex in the chicken.  It is basically the reflex that we use to keep our eyes firmly focused on something while our head is moving. In a chicken however, they move their entire head. This means that he can strap a camera to the chicken’s head and have an instant steadicam. At least that is the theory. As you can see in the video after the break, the harder part is getting the chicken to look at what you want it to look at. We also found a conversation about it with the creator,[MrPennywhistle] in some reddit comments.

Triggering a DSLR shutter with an audio clip

Apparently Pentax DSLR cameras have a remote shutter option that used infrared signals. [Pies for you] gathered up several different hacks and built a method of triggering the camera using custom audio. He put together the dongle above, just a headphone extension cord and two IR LEDs, which plugs into the headphone jack of any audio device like an iPod or an Android phone. When you play back a file the audio signals drive the IR LEDs. This is completely worthless unless you craft your own audio file using the correct frequency, duty cycle, and bit encoding. [Pies for you] did just that and got things up and running. Looks like the system doesn’t do so well with MP3 compression, but take a look at the waveform analysis that he posted and then make sure you’re using a lossless format.

Remote camera trigger built from air freshener parts

[jcopro] took a look at a Glade automatic air freshener he had sitting around and couldn’t help but open it up to determine how the mechanism worked.  After taking it apart, he found that the automated system was comprised of a 3v motor, a series of gears, and a mechanical arm.  When actuated, this arm simply pressed the spray nozzle of the air freshener canister contained within the device.  After some consideration, he decided that the components would make a great remote trigger for his Casio point and shoot camera.  He fabricated a small plywood rig including both the camera and air freshener components, which was able to be mounted on a tripod.  [jcporo] also mentions that the air freshener has the ability to be triggered by a built-in timer.  Although the presets are locked at 9, 18, and 36 minutes, he suggests that a 555 timer could easily be used to add some custom timing intervals when wired to the manual trigger.  Be sure to check out his video of the remote trigger in action.

Bringing an LCD viewfinder back to life

[Foobarbob] posted a pretty simple job of bringing an LCD viewfinder back to life. He doesn’t specify what was wrong, but since he replaced the backlight, we’re guessing that was the main issue.  It was pulled off of a JVC camcorder. The camcorders with LCD viewfinders are getting more and more common at garage sales, so we’re surprised we don’t see more of these used. [Foobarbob] cracked it open, traced out the power lines and replaced the backlight with an LED and a makeshift diffuser made from a bottle cap. His results look great, we could see this being perfect for an HMD, or possibly a home made VR helmet.
