    If you don't hack the camcorder, you're paying $2 and change a minute to buy it, record 20 minutes, and have those 20 minutes put on DVD. Considering how many obvious artifacts were in the demo scene from the DVD, I am ready to boycott CVS just on principle. Charging that much money for such crap!

    Now the obvious answer is "hack the camcorder. Then it doesn't cost so much and you get more value for your money." Hmmmm... I can get a 16 ounce sh*t-flavored milkshake for $3, but with a little trick, I can turn that into a gallon. What a bargain, so long as I don't mind that it's still sh*t-flavored. If I want more sh*t-flavored goodness, then darn, I better learn the trick. If I want a milkshake that doesn't taste like sh*t, I think I'd better save my pennies.

    The ONLY reason I can think of getting this is to get a camcorder for your kid. If they break it, big deal.

    It also sort of reminds me of that old Mattell video camera that recorded grainy B&W on audio cassettes. Though crappy, it has its own kind of retro cool if you can find one now. Perhaps these cameras have value as collectors items.

      Wow, if you don't like a deal someone is offering, just don't take it. Show me a store that isn't charging too much for something or that offers something that doesn't present a value proposition that you accept. You're going to have to be self-sufficient if you start boycotting all of 'em.

      I'm thinking of getting a weather balloon and tying one of these on to see what happens. $30 sounds good.
    • The video really isn't quite as bad as you're describing. Pict0004.avi is actually fairly decent (shot at the highest datarate) and is about the same quality as a VHS tape recorded at extended play.

      Maybe that kind of quality isn't usefull to you, but for many people that kind of quality is decent enough to be usefull. For someone on a small budget, $30 ($20 with coupon) is actually affordable, where $200-$300 for a real digital camcorder isn't at all.

        Yeah but you can only use it for 20 minutes unless you steal it from CVS. If you're going to do that, just go to rent-a-center and get a nice camcorder for free.

        • By my calculations 417 kilobits/sec in 128 megabytes of flash would leave enough room for 42 minutes of video. That's pretty decent.

          I guess I'm not sure what you mean by "steal it from CVS". Is CVS only renting the camera, and you're expected to return it? I don't see any references to that anywhere. Unless you have to sign something when you buy it saying you'll return it, that camera is yours to do with whatever you please. Don't blame hardware hackers if CVS chose a bad business model.

              And an article in todays Star Tribune http://www.startribune.com/stories/535/5475334.htm l [startribune.com] says that there's no security deposit, and you don't have to return it if it's broken. That doesn't sound like a rental agreement to me. Coupled with the fact that there's no rental contract, I'd say "rental" is just a convienent word to use for people to describe the arrangement.

              So if I ask to borrow your car to drive 20 miles, and I don't sign anything, I can take your car on a 2000 mile trip, turn back your odometer, and get away with it?
              This isn't an informal "borrow a car from a friend" relationship. This is a storefront where people buy things and if a contract is involved, it's spelled out quite clearly. In this case, they sell you the camera, and then hope you'll bring it back.

              A contract doesn't have to be signed in order to be binding.
              No it doesn't but you do have to have at least a verbal agreement to have a binding contract. Unless they say whenever you buy one of these things "buy buying this product you agree to return it" then you have no obligation whatsoever to return it.

              Sure, you might get away with breaking it, but that doesn't mean you're not stealing.
              Gee.. I thought stealing meant someone took something from you without you giving it to them, or selling it to them. Since CVS is actually selling these things to consumers, there's no "theft" involved. If you want to co-opt the word theft to your own personal definition, fine. But don't go around using it that way and expect people to agree with you.

      That was my thought with the first disposable digital camera. IIRC, I didn't find an obvious erase in the firmware, but that's a moot point because I never found a recycled camera. The camera wasn't really designed to be recycled -- it had a surface that could easily be scratched, even with very light use.

      The second still camera (the PV2) has a USB function that sucks out all the important system files out of Flash memory and saves them in SDRAM. It then reformats the memory and copies the files back in. It's a pretty good erase (maybe not NSA secure, but recovery would involve probing the IC wafer), and I don't see why it wouldn't be used.

      But, the biggest security risk seems to be the time after development and before sending the cameras back to Pure Digital for recycling. According the people who operate the machines, the development machines don't erase the pictures. They stay on the camera in case something messes up -- they didn't want to have angry customers saying "what do you mean you accidently deleted my prints". It seems that the used cameras stay a while at the stores, so any operator could make prints of your pictures for up to a couple of weeks after you have them developed. But, bad employees is probably about the same risk as with traditional development.

      Since the camcorder uses a separate partition with only picture data, I suspect it would be pretty easy to reformat only this section completely. (the PV2 had system and user data in the same filesystem, which is why it had to save the data in ram)
  • I wonder, if these people based their camcorder MPEG-4 encoding using the actual XviD codebase, where's the code? (not sure, but is XviD LGPL or GPL?)
    I also wonder if they paid the MPEG-4 licensing fee too. (probably on that one)

    Disposable Digital Camcorder Interfacing

    Pure Digital's Single Use Camcorder for CVS

    [PureDigital CVS camcorder]

    Introduction
    This web page is a little raw because I just got the camera and I'm leaving on a trip soon. So, I'll be brief and hopefully informative.

    If you're not familiar with the camera, here is a good review.

    Disassembly
    Here's a photo gallery of the disassembly of my unit.

    Similar in constructioon to the PV2, this unit is rugged and can be easily recycled.

    Preliminary Analysis
    Others found that pressing the Record and Delete buttons while turning on the camera yields a special diagnostic page. Mine said:

    FW-VERSION: 03.40
    CAMERA ID:
    6B7051xxxxxx
    PCB VER: B2

    FLASH Memory Analysis NEW
    I was able to get my videos out of the camera and onto my home computer by removing the 128MB flash memory chip and putting it into my home-built flash reader. I originally built the system for the PV2 camera -- here's some more info on it. The only modification I had to make was for the increased memory size of the new part. The reader is nothing special -- just a cheaper (and slower) version of comercially available units.

    I've placed my analysis of the camcorder's flash memory on its own page. That page also has sample videos I have recovered from my camera.

    Resources
    The most current discussion that I follow is on the Camera Hacking message board. There is also discussion on Dakota PV2 discussion board.

    Is this legal? Yes.
