$50 Aerial Digital Photography from a Balloon 205
jizmonkey writes "This guy built
a balloon to
take digital aerial photographs from thousands of feet up. It cost
less than $50 altogether, including the image sensor, controller, and
balloon. The circuit is surprisingly straightforward: just a hacked Vivitar
minicamera, a 555 timer
chip driving a relay through a voltage regulator, and a one-meter
party balloon like the ones you see at used car dealerships. It just so
happens that the entire circuit, strapped to a piece of a pizza box and
tied to a really long string, is light enough to be lifted by the balloon.
What could low-cost aerial photography be used for? I'm sure some people have
some ideas...."

The reason you would do this is not to get just any pictures from the sky, it's to get YOUR pictures from the sky. Like a picture of your house, or your car, or your neighborhood (all of these with you standing in the picture (or out of it depending on how YOU feel) controlling where the balloon goes to take pictures. Not an archived photo of someone elses. And that's $50 A MONTH, not close to a one time fee of $50.

Now, I've seen a "digital single-use cameras" from Kodak which just used film, and the only thing "digital" about them is that when you send them in for processing, they scan the negatives and send you a CD along with the prints.
But this one SAYS "Delete and Retake Last Shot," which, to me, suggests that it really IS digital. It's $10.99. It says it will take 25 images. No indication of resolution. And no indication of precisely what you do after you have taken the pictures.
I probably need to get one and crack one open. It sounds like a very interesting device for hacking.
It will be very annoying if it turns out that $10.99 means that you pay $60.00 up front and get $49.01 back when you bring it in for "processing," though.

Ok, second idea. What about some wireless hookup for the digital camera, so that you could put a camera up there, and not take it down often, but control the camera (zoom?) - or at least take the pictures, and then transfer them to the ground. I would think that this could really rock. Get 4-8 of those party balloons (at what point is this a 'weather balloon' and are there any laws about these?), so you could pick up 2-4 lbs, then, mount the stuff on a little box.

Its interesting to note that there are lots of methos for creating unstructured panoramas. Where you have a set of images and the algorithm does its best to determine how to stick the images together to form a panorama.

Weight reduction & circuit suggestions... (Score:3, Interesting)
First, I don't see a protection diode on that relay. You need a diode that will be normally reverse-biased on the coil... otherwise, when the relay clicks off, the inductance of the coil will kick back enough voltage to blow out the 555. It's a reliability issue.
Second, the 555 is a nice analog circuit that's rated for 4.5-15 volts, so no need to use a 7805 voltage regulator; you can connect to the battery directly.
Third, a battery idea: Radioshack has some 12 volt batteries that are about N-size (sub AA). They are typically used for lighters, pagers, or remotes.
Lastly, as you mentioned, the ultimate would be to get rid of the relay and connect directly to the camera. The CMOS version of the 555 would be ideal because (1) it's low power, so you might be able to drive if from the camera's step-up power supply and (2) it has a FET output, so it'll drive much closer the the GND&VCC rails than the TTL version (this should help compatibility)
