New Disposable Digital Cameras with LCDs
del_ctrl_alt writes "Pure Digital Technologies are set to introduce the world's first ever disposable digital camera [ed. note: see below], retailing in the USA for $19.99. Ritz, CVS, Disney World and Longs Drugs are all going to stock the 2-megapixel camera, which somewhat amazingly has a color preview screen and allows you to delete images before you take it to the store for processing (where you will receive a free picture CD along with your prints)." It's not the first disposable digital camera, which was hacked shortly afterwards, but these include a LCD display (they're made by the same company which made the first ones). Have fun!
Film processing is expected to retail at $280 per camera.
How long before "disposable" becomes "free" with a simple hardware/software hack?
"Have you ever thought about just turning off the TV, sitting down with your kids, and hitting them?"
I really hope it is hackable. I mean, a 2 megapixel digital camera with LCD for $19.99 would be a pretty good deal, even if it takes a day or two, and even 1 or two broken cameras first. I hope someone comes up with a hack!

For exactly which economic bracket is $20 considered "disposable"? I consider myself middle-class, and I'm not going to throw anything away unless it cost under $8, if I can help it.
You don't throw the camera away. You take it back to the drugstore for processing, where they reset, refurbish and generally sell it again.

Preliminary stuff of interest
The edge connector of the PV2 electrically matches that of the classic Dakota, at least as far as the USB pins go; whatever cable/contraption used to access the classic should work for this one without modifications.
Holding down ALL the buttons at once (shutter, Display, Delete) while turning on power will display a diagnostic screen showing the camera's serial number, firmware revision and similar information.
See John's Dakota page with an update for the PV2, including some USB info, datasheets for the more interesting parts (including the LCD) and a gallery of good dissection photos.
USB info
Here is the dump-out from SUCR commandline, walking thru the device properties. (All versions of SUCR do this, in case the manufacturer decided to get clever and move the devices/interfaces/endpoints/altsettings around). This gives a good idea of the 'organization' of the camera's USB interface.

The camera has 2 configurations, one is for 200mA and the other is for 100mA, but "seem" otherwise identical. (See the testlibUSB dump-out below for additional details.) When the configuration is set by SUCR, the camera emits a 2-tone ascending beep, and the LED comes on. However, regardless of which of the configurations is used, all control transfers produce a CRC error message from Windows: LIBUSB_DLL error: error sending control message: win error: Data error (cyclic redundancy check).

Is it possible to make something like this that's more trouble to hack than it's worth? How much work would it be?
Embedded CPU with built-in mask-programmed or fusible-link ROM. Encrypted images in the flash, with the key in the CPU's ROM so it can't be read out. It shouldn't be impossible to lock something like this down hard enough that it'd cost more than the value of a cheap digicam to unlock it.
huh? why exactly is it a _bad_ idea, if they just can make it profitable?
ever used crappy disposable cameras? the worst thing about them is that a lot of the pictures you take turn out as total crap. a preview screen on them would be a great improvement.
it's a replacement for MEGACRAPPYSHIT disposable cameras, and a lot of folk visiting disneyworld or whatever would like one of these. it's cheap for them(customers), so they don't have to have even any stress about if it breaks in the rides or if they lose it and yet they can take better pictures than with a normal disposable one.
20$ for a rent of a 2mpix camera and service to get the pics on a cd isn't _that_ bad at amusementparks & etc..
world was created 5 seconds before this post as it is.
Forget the 2megapixel camera, I want cheap LCD's.
Hopefully the hardware gurus recycle all of the parts, so we can have a webcam, a display, and a memory stick, all for the low low price of $20.00
A $20 color LCD for all your cool projects!
Of course, in this case Disposable == Recyclable. Or do you really think they simply pitch the 2 megapixel CCD sensor, LCD display, internal memory, camera body, etc. in the garbage after you bring it in?

I did the original hack on the old camera, and, of course, I'm working on the new one... here's my web page on it.
The next step is a ROM dump -- then we can see if there is any code in the flash memory, or if it's stored on the ASIC. I suspect that there is a bootloader on the ASIC and the bulk of the code (certainly the pre-programmed images) is on the flash. Don't know if it's encrypted or scrambled yet.
We're still working on the resolution of the sensor. I read the part number last night, but didn't return any google hits. We can't really rely on the size of the pictures one would get back from processing because, in the past, they've upscaled it.

The first disposable digital camera was the SiPix Blink I got for $50 from Fry's. After using it, you want to throw it away even if you have the receipt, because you want to prevent any other human being from undergoing the sheer torture. I looked at the $50 as a charity expense.
What's your damage, Heather?
that I should google first but... I haven't had my quota for abuse today:
Has anyone done any cool hardware hacks to utlize a digital camera's LCD for other purposes? (thinking case mod, mp3 jukebox (like a real jukebox (friend's site), not an ipod) display.
my understanding that trying to use an old laptop's LCD (separate from the laptop) is near unpossible or not worth the effort...

Don't expect it to look better than the 1.2 Megapixel camera it really is.
LCDs are manufactured using an resource-intensive process, AFAIK, with large volumes of contanimated water as a waste product, and large volumes of dangerous chemicals being used/reused/disposed in the process.
The same goes for CCDs and the electronic guts.
How the fuck can anyone conceive this as a good idea? What an utter disregard for the inheritance of our children!
That said, I want one, just to hack. But, shit, surely we humans have *got* to get a clue one of these days.

Why do people insist on calling these cameras disposable?
The business model is basically to rent them out for a rather steep $20, which gets you use of the camera until you fill the on-board memory and then a CD with your images after.
My guess is that the retailers have a minimal markup on the camera with the expectation that they will make their money doing digital prints.
The manufacturer makes their money by being able to rent the same camera multiple times.
Certainly some of the cameras will be "lost" to hackers, but this is a cost of doing business and is probably far cheaper than creating and inforcing some sort of deposit mechanism since, for the average user, the "deposit" is the precious memories stored on the camera that they can only get back by returning the camera.
If "hacking" of the cameras become widespread, then one can expect that the company will either take action or go out of business.
If they take action, there will no doubt be much grousing among the slashdot community, but really, what right does a parasite have to complain when the host its bleeding dry seems to extingish it? Better to keep a low profile.
I'd be willing to overlook the common misuse of "LCD" with "display" if it's prefaced with "an", as in "an El See Dee display". But beginning it with "a" makes it a clear case of saying "a Liquid Crystal Display display", which is just plain wrong.
If a job's not worth doing, it's not worth doing right.
Why does society insist make making more and more disposable crap?
Because at the rate (this) technology is advancing, you might as well consider all digital cameras disposable within a few years. Also, there are people who demand desposable cameras so they won't be afraid to take it on their mountain climbing trip.
This whole disposable movement just evolves us to making more stuff that has lower and lower quality.
Yes, because we all know that this 2 megapixel camera with LCD display is of extremely poor quality as compared to the 1 megapixel cameras that cost several times more. (Won't even bother to tell you that these are returnable, not disposable)
Hence the saying "They don't make 'em like they used to."
Reminds me of another old saying, "Do not say, 'Why were the old days better than these?' For it is not wise to ask such questions." -- Ecclesiastes 7:10
it is not wise to ask such questions." People have been complaining about how good the old days were for 3000 years already. Maybe you should just accept progress and be happy with our improvements in medicine, travel, etc. (You can mod me down now, for mentioning the bible.)
Don't waste your vote! Vote for whoever you want, unless you live in a swing state it won't matter anyways
It'll cost 20 bucks at the local Rite Aid, but I can guarantee you that once past the gates of Disney, it'll cost at least 40 or 50. Or any other amusement park, for that matter. Enough that it'd negate any economy. But, you forgot your own camera, so you pay.
Actually, I envision the park security no longer allowing you to bring your own camera. You know, to improve safety and give you a more enjoyable experience.
Hey, a bottle of water costs 3 bucks in there.
I don't need no instructions to know how to rock!!!!
The LCD is detailed on the Maushammer pages. DataSheet for the LCD is here.

I know most of the people on here are looking at this as an opportunity to get a usable digital camera for cheap (with a little elbow grease), but even if the attempts to hack it aren't successeful, the camera is still worth more than they're selling it for. You see, for hobbiest electronics people, LCD screens are ridiculously expensive. In single quantities you'd be lucky to get a lower resolution, monochrome LCD display for twice the cost of this camera, more likely three times the cost. LCD screens, more than any other products are given great discounts in bulk and huge price inflations in small quantities.
This whole thing depends on "taking the camera back to the store". What's wrong with this picture?
There's a desperate, last-ditch attempt by the camera industry to re-introduce consumables into a product that no longer needs them. Expensive incompatible flash memory cards, expensive special paper for inkjet printers, and, of course, the "printer ink" industry all fit this model. They're just delaying the inevitable.
Incidentally, the inkjet situation should open up in a few years. Key patents are approaching expiration. The basic bubblejet patent expired this year.
