808 camera hack produces a time-lapse Tic Tac box

It’s not really conceived as a spy cam, but it could be. [Quinn Dunki] built this tiny time-lapse camera project with racing in mind. She’s involved in a group that endurance races clunkers, and part of the fun is sharing the experience of riding around in the old beaters. The module seen above takes a picture every four seconds and will last 24 hours before needing new batteries or an SD card change. We wonder if that’s longer than some of the ‘racecars’ make it?

She picked up an 808 camera, which looks like the key fob you use to unlock your car doors. They’re so cheap you can include them in projects and not really care if you don’t get them back. Inside it’s got a small lithium battery, the circuit board with a processor, microSD card slot, and of course the SSD used to capture the images. To control the device she used a tiny relay with an ATtiny13 used for the timing. We think the battery selection is a bit overboard, but maybe the next version will be a little more conservative.

There was one folly along the way. She wanted to attach this to the body of the car with a handful of magnets. But they don’t play nicely with the magnetic relays so that was out. The solution was to add that lanyard ring to the case which will allow the camera to be zip tied to the vehicle. So far there are no time-lapse movies available, but keep your eyes on our links posts and we’ll try to include one when it pops up.

Solder Your Pin headers Straight

If you’re worried about how to solder your pin headers straight, why not try this simple trick and put them into a breadboard before soldering?

Etiquette for Open Source Projects

soapbox Phillip Torrone

If you use or develop open source projects, it’s worth checking out [Phillip Torrone]‘s Unspoken rules of Open Source article. You may not HAVE to do all the things he says, but it’s certainly a good starting point for being ethical with your hacks.

The [GoAmateur] Camera Mount

go-amateur camera mount for bike

If you can’t afford a professional camera mount for your bike, why not make one yourself? As pointed out in the article, normal cameras aren’t really made for this, so do so at your own risk. If this isn’t shoddy enough for you, why not make a mount for your 4 year old dumb-phone (Env2) out of a block of wood?

A 3D Printer BOM

If you’re wondering how much a 3D printer will cost you, or where to source the parts, this Bill of Materials for a Prusa Mendel should help. We would assume this project will be updated as everything is built, so be sure to check back!

MakerBot Assembly Time-Lapse

Along the same lines, if you’re wondering about getting into 3D printing, this time-lapse of the Thing-O-Matic being assembled may give you some insight into what’s involved in getting one functional!

The Picture Post – Observe Your World in Extreme Slow Motion

The “Picture Post”, a tool for a program going on through the University of New Hampshire, is a method of taking what amounts to extreme time-lapse photography. The purpose of this project is to observe the world around you with a 360 degree view taken at a regular interval.

The setup is quite simple consisting of a 9 inch diameter post, and an octagon to set your camera against.  Just place your camera one edge, take the picture and repeat around the octagon until done. You can register on their site to make your post official and contribute to society’s general knowledge about the environment and seasonal changes.

Although interesting in itself, this concept could be applied to many situations that one would want to record in this manner.  For instance, a “hacker post” could be set up in a hackerspace for members to record their projects on or even the progress of the building itself.  For another much less developed way to take photos, check out this trigger device using air freshener parts!

Panning time-lapse rig

Here’s a simple camera setup that lets you make your own panning time-lapse videos. It uses a couple of motors driven by an Arduino to snap successive still images which can later be rolled into a video format.

[Acorv] was not thrilled with the fact that his new Lumix LX5 didn’t have a time-lapse option built-in. But luckily it does have a standard connector on top for an external flash. He saw on a forum post that someone had built a jig which mounts to the flash bracket and uses a servo motor to depress the shutter release button. He recreated that and had half of this hack done.

The panning portion is facilitated by the Gorillapod. This particular model offers a swivel feature. This is automated by connecting it to a stepper motor with a piece of string. As the stepper turns the string is wound on a spool and gradually pans the camera. Simple, and it seems to work great. Check out the video after the break to see a test which was shot at sunset on the shores of a lake.

If you have a camera which offers an IR remote shutter release the time-lapse portion can be handled with an IR intervalometer, making the mechanical build a bit easier.

Extending battery life while taking time lapse photos

msp430_camera_control

[Peter] loved using his GoPro HD camera, but he found the time lapse functionality a bit lacking. It wasn’t that there were not enough settings to satiate his needs, but that the camera would run through its batteries in just a few short hours.

He found that the camera did not turn off or enter any sort of sleep mode between shots, wasting precious battery life. He could have simply added a bigger external battery pack to the camera, but for the sake of portability, he had a far better idea in mind.

The GoPro has a pretty well documented interface called the “Hero Bus”, so all it took was a little bit of online research before [Peter] had all the information he needed. The camera has a neat feature that immediately snaps a picture when it is powered on, so he decided that he would use a microcontroller to turn the camera on and off at specific intervals, rather than using its built-in time lapse function. He chose a Texas Instruments MSP430 for the job, since it is very well known for being a power miser.

Once he had his code up and running, he connected it to his camera and found that it worked perfectly right off the bat. Now, he can take anywhere between 1,500 and 2,000 shots before the batteries run out, instead of the measly 200 he was getting without the modifications – quite an improvement!

Build cheap panning camera mounts for time lapse photography

diy_ikea_panning_camera_mount

Panning time lapse photographs always look pretty cool, but there’s that whole “making a panning time lapse” rig that gets in the way of all the fun. [Getawaymoments] put together a tutorial quite a while ago showing how to use Ikea egg timers as cheap and dispensable panning units, and has updated his instructions with a pair of refreshed designs.

He stumbled upon two new egg timers at Ikea, the Stam and Ordning, which sell for $1.99 and $5.99 respectively. The Stam is a small plastic model that can be fitted with a set screw, to which most cameras can be mounted. A small bushing can also be installed in the timer’s plastic base, allowing it to be mounted on any standard tripod.

The Ordning is a beefier unit capable of withstanding more abuse than its plastic brethren, hence the larger price tag. A few minutes on the drill press makes room for a metal bushing, allowing the Ordning to be installed on any tripod as well.

The hack isn’t high tech, but we’re impressed with the results he was able to get with these simple kitchen timers. For the cost and time required to build them, they are sure to give most other panning rigs a run for the money.

[Bunnie] mods Chumby to capture epic time-lapse video

When [Bunny] moved into his apartment in Singapore he was surprised to find that a huge building project was just getting started on the other side of the block. Being the curious sort, he was always interested in what was going on, but just looking in on the project occasionally wasn’t enough. Instead, he set up a camera and made a time-lapse video.

This isn’t hard, you can find a slew of intervalometer projects which we’ve covered over the years. But being that [Bunnie] is one of the designers of the Chumby One, and frequently performs hacks on the hardware, it’s no surprise that he chose to use that hardware for the project.

Luckily, he’s sharing the steps he used to get Chumby capturing images. He mentions the hardest part is finding a compatible USB camera. If you have one that works with a 2008 Linux kernel you should be fine. The rest is done with shell scripts. Mplayer captures the images when the script is called from a cron job. Once all the frames are captured, he used mencoder to stitch the JPEGs into a movie. See the result after the break.
