Simple Power Adapter Thumbs Its Nose At Proprietary Connectors

June 5, 2012 by Mike Szczys 19 Comments

[Mike Worth] wanted to use his camera for some time-lapse photography. Since it’s used to take many pictures over a long period of time, he doesn’t want to deal with batteries running low. But there’s no standard power jack on the side; instead the official charger consists of an adapter that is inserted in place of the batteries. Rather than break the bank with the special cable, [Mike] made his own battery compartment A/C adapter.

You can see that it is made up of two parts. The first is a standard wall wart that outputs the correct voltage and has an acceptable current rating. The other part is the adapter cable that connects to the camera on one end, and has a barrel jack on the other. [Mike] rolled some paperboard around a pencil until it matched the diameter of a AA battery. Once of the cylinders has a thumb tack for the negative lead, and the other uses a screw and washer for the positive side. He soldered some wire to these and he’s in business.

He must be snapping photos frequently enough to avoid the auto-shutoff feature. That or he’s disabled it with the use of some custom firmware.

Amazing ass… for a robot

Yep, Japan still has the creepy robotics market cornered. Case in point is this robotic posterior. Don’t worry, they’ve included a dissection so you can see how the insides work too. [via Gizmodo]

Time-lapse camera module results

As promised, [Quinn Dunki] sent in a link to the photo album from her time lapse camera module. In case you missed it, she built it in a Tic Tac container and stuck it to the side of a racecar.

Kinect controlled killbot

Didn’t we learn anything from RoboCop? We could totally see this Kinect controlled robot (which happens to weigh five tons) going out of control and liquefying an unsuspecting movie extra standing near it. [via Dvice]

Laser popping domino balloons

apparently [Scott] has set a world record by using a laser to pop a line of 100 red balloons. We enjoy seeing the size of the 1W laser that does the popping… it can’t be long now before we get a hold of handheld laser pistols. [via Gizmodo]

Laser balloon targeting

If that last one was a bit of a let down, you might enjoy this automatic targeting system more. The blue triangle shaped icon is setting a target, the amber triangles have already been targeted. Once all the balloons are identified a laser quickly zaps each in order. Quite impressive, although no details have been provided. [Thanks everyone who sent in a link to this]

Autonomous Time Lapse With A Video Camera Throwie

April 12, 2012 by Brian Benchoff 12 Comments

When [Matt] came across a small video camera made to fit onto a keychain, the first thing that came to mind is a time-lapse video throwie. Like the LED + coin cell battery + magnet we’ve seen we’ve seen before (and deployed…), [Matt]’s video throwie would be deployed in interesting spots for a few days and shoot a time-lapse video until the battery ran out.

The camera [Matt] picked up has the capability of shooting video or still pictures and writing them to a microSD card. To make his camera film a time-lapse video, [Matt] connected an ATtiny45 to the camera shutter and power buttons and uploaded a short bit of code that would snap a picture ever 15 seconds.

Right now, [Matt] is having a few problems with his video throwie. When the camera is turned on, it iterates through the SD card to find the next unused file name. This eats up a few seconds, so the current setup will slowly speed up the time-lapse video. This isn’t an insurmountable problem, so we’re looking forward to the very interesting videos these tough little cameras will film.

Check out [Matt]’s video of ice melting after the break.

808 Camera Hack Produces A Time-lapse Tic Tac Box

March 29, 2012 by Mike Szczys 9 Comments

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

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

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

November 22, 2011 by Jeremy Cook 9 Comments

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

November 8, 2011 by Mike Szczys 4 Comments

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.
