    I used to live in Bowling Green, OH and while I was searching around for caches to do in the area (and talking to someone I knew from Toledo) I was directed and half stumbled upon this [geocaching.com] cache. Basically you need to take pictures from the air of an assigned number. The cache owner didn't particularly care how you accomplished that (whether it was by plane or some more inventive means).

    Well, this [geocaching.com] group did it with helium balloons, ethernet cable, and a webcam. Just as inventive, a lot less solder, and if your picture taking device falls you aren't completely out of luck as it may actually survive the fall.

    The only difference I see is that you aren't going to be able to have pictures with the same quality which is certainly a bummer but the coolness/geek factor certainly is way up there :)

      We used a deep cycle battery and a power inverter. The cam was an Axis 2120 network camera. We stripped the insulation and one of the pairs from the ethernet cable, used the remaining pairs for data and a hacked power over ethernet solution for the cam.

      Set the axis up to FTP an image to an iBook at the other end every 5 seconds. We ended up with over 300 images to dig through and found about 20 decent ones.

      • Seriously what are you talking about? A 555 timer is a great little cheap chip. The HC series of microcontrollers cost upwards of 100$ a pop. I doubt the chips cost a cent each if bought in bulk. Just look at it in froogle - you can buy individual ones for 50 cents. I defy you to find a microcontroller at that price, or 10x that price. Maybe at 100x time price you will be getting somewhere.
        • Actually, some microcontrollers just about as cheap as the 555 -- $1 to $2 or so. But often you need to upload firmware into them, and that complicates matters greatly, especially if you need to write that firmware yourself.

          For example, I've been looking into building myself one of these [rc-cam.com] for R/C aerial photography. The microcontroller used can be ordered for $1.50 -- but then I need to find somebody who can program it for me (or buy the equipment, which isn't very expensive.) I may just go ahead and

              If I'm reading the spec sheet right, the LM555's typical current usage is 3 mA of current at 5 volts. I'd say this usually falls into the `who cares?' category, at least for this purpose. (Certainly, for many applications, 3 mA is a big deal, but I don't see this as one of those.)

          The lowest cost 8-bit microcontrollers by Atmel, Microchip, Ti, Motorola are around 1$ or less. And you already get quite a bit for that amount of money. Motorola announced the first MCU priced 50cents in high volume years ago.
