Hunting Down Farmyard Pests With Technology

hunting_with_a_camcorder_night_vision_scope

[Snypercat] makes no bones about the fact that she despises rats, and does everything in her power to keep them off her farm. We can’t blame her though – they spread disease, eat other animals’ food, and can get your farm shut down if there are too many running about. While most of us might hire an exterminator or set out a ton of traps, she chooses to take a far more hands-on approach, hunting down each and every one of those little buggers with an air rifle.

If you’ve ever gone rat hunting in the dark (and who hasn’t?), you know that it can be difficult to aim in the dead of night. Night vision scopes can be expensive, but [Snypercat] shows how you can make your own scope that gives you the added benefit of recording your kills along the way. She happened to have a Sony camcorder with built-in night vision capabilities, and with a bit of tweaking she was able to mount it on her rifle’s scope. An IR flashlight was mounted on the rifle as well, giving her enhanced visibility without spooking her prey.

Be sure to check out the pair of videos below to see how [Snypercat] attached the camcorder to the scope, along with how well it works in the field.

Go Ahead, Let The Kids Play With Your Digital Camera… After Some Additions

Would you throw this camera around on pavement and trust that it wouldn’t get broken? We have a hard time believing it too, but that’s exactly what happens in the video after the break. The colorful add-ons are pieces of Sugru creatively positioned to help protect the camera. From what we’ve seen this adds quite a bit of shock absorption, letting the normally delicate hardware bounce and roll. After all, the stuff is made from Silicone.

It doesn’t look like the protection is meant to be removed from the camera, although we have seen Sugru used for that in the past so this method may be adaptable. A mistake was made during the project which prevented to battery compartment from being opened but it turns out you can peel the stuff of the camera later on, so this isn’t a completely permanent transformation.

We’d wager the camera component to be most concerned with is the LCD screen. We’ve got one that cracked without any plausible cause to point to. But if you’re just reinforcing the device to hand to your kids, who cares if the LCD doesn’t work? It kind of makes it like a film camera again if you have to take all the pictures and then wait to use a computer to “develop them”.

Don’t forget, if you don’t have Sugru on hand you can try mixing your own.

Homebrew Weather Station Plus A Pan And Tilt Camera Rig

[Sebastian] wrote in to share his web site, where he has a bunch of different electronics projects. After looking through them, we found a pair that we thought you might find interesting.

The first project is a homebrew weather monitoring station that [Sebastian] put together. He designed a weather shield, incorporating humidity, pressure and light sensors, along with digital I/O ports for monitoring an anemometer. The entire setup is powered using solar panels, and data is relayed to his computer via an Xbee.

The second item that caught our eye was a digital camera pan and tilt rig. The system was built using a Lynxmotion pan and tilt kit, which is controlled by an Arduino. The code he provides allows him to capture very large composite images without having to spend too much time “sewing” them together. While this second project mostly consists of schematics for a base plate and pan/tilt code, it struck us as something that could be very useful for any budding photographers looking to take panoramic shots.

All of the schematics and code for his projects are available on his site, so be sure to look around – you might find something interesting!

Using An MSP430 For Time Lapse Photography

vistaquest_keychain_timelapse_msp430

Hackaday reader [onefivefour] had an old VistaQuest VQ1005 keychain camera kicking around, and wanted to do something useful with it. A while back he hooked up a 555 timer and did a bit of time lapse photography, but he wanted more control over the process. Specifically, he desired the ability to tweak the delay between shots in a more granular fashion, as well as way to prevent the VistaQuest from going to sleep after sitting idle for 60 seconds.

His weapon of choice to get this task done was an MSP430, since the microcontroller can be found quite cheaply, and because it is relatively easy to use. He added a few header pins to the LaunchPad board wiring them up to the camera’s trigger as well as the on/off switch. When the wire connected to the trigger is pulled low, the camera snaps a picture. The wire connected to the on/off switch is always held low, ensuring that the camera is on and ready to go whenever it’s time to take a shot.

It’s a relatively simple project, but definitely useful. While there are many ways to build an intervalometer, the MSP430 is a great platform to use, especially for beginners.

Stick around to see a quick video [onefivefour] put together, showing off his time lapse rig’s capabilities.

Two-axis Panning Time Lapse Rig Built From Lego

2_axis_lego_timelapse_dolly

[Jochem] wrote in to share a neat time lapse camera dolly he constructed out of Lego bricks. He is a big fan of the two-axis panning time lapse effect where the camera moves while recording images. He figured it would be easy enough to construct one of his own, so he dug out his pail of Lego and got to work.

The rig consists of a stationary motor platform which pulls a movable sled using a simple gear and string. The motor platform is controlled by an Arduino, which pulls the movable sled along every so often, snapping pictures along the way. [Jochem’s] Nikon D80 supports shutter release via IR, so he programmed the Arduino to send a quick IR pulse each time it has finished moving the dolly.

The rig looks like it works pretty well as you can see by the video below, but [Jochem] says that it still needs a bit of work. We just can’t wait to see what other time lapse movies he puts together once he finds an “interesting” time lapse subject.

Play-by-play Of A High Altitude Balloon Flight

[Greg Intermaggio] and [Shumit DasGupta] at Techsplosion launched a high altitude balloon last week that climbed to 90,000 feet above sea level somewhere over California. The play-by-play of the flight is one of the better stories we’ve seen on high altitude balloon builds.

The balloon, christened VGER-1, carried a SPOT satellite GPS messanger to send telemetry back to the ground. We’ve seen a few home brew balloon tracking devices, but [Greg] decided to use an off-the-shelf solution for the sake of simplicity. Like other balloons the VGER-1 carried a CanonPowershot camera with CHDK firmware.

Sound Activated Flash For High Speed Photography

High speed video is everywhere these days, but the cameras and necessary equipment is a bit out of reach for a hobbyist. [Bassam] found a compromise and came up with a way to shoot high-speed photographs using a sound triggered flash.
