Examples:
a. Hold the OneScan fridge magnet onto a drawing. Press
the button. The OneScan is now a fridge magnet with the
message.
b. Hold the OneScan business card and you have the image
of your business card in your hand. The guy you give it to
can store other business cards and go
through them.
c. Hold the OneScan picture album to old images and scan
them directly in. This one also has a memory card.
Use a tiny LCD screen and one or two buttons for input.
Use a low cost camera, and scan in slowly and focused, or
maybe some other digital or optic method. - I'm leaving
that for the engineering second half.

Amazing, lens + CCD + flash memory + LCD + battery + microprocessor = $3. I'll take two! |
|
| |
I too am impressed you can do all this for $3 |
|
| |
ha that's nothing - somebody else is proposing a jet
engine for 25 cents |
|
| |
No, the flash memory one is more expensive. $10. |
|
| |
Low res CCD (on Alibaba) at 10K units: 80c. |
|
| |
Microprocessor: (e.g. COP888EK from National
Semiconductor) 49c. |
|
| |
LCD: http://www.yes-lcd.com/yes/ Less than a $. |
|
| |
Mounting said CCD, lens, processor and LCD - $2. Components to mount it 50c ea (3-4). Wiring and wiring assembly, $2-3. Clean room facility to do assembly, $10,000,000 (admittedly not per unit). Sales and marketing ~$2-3. Profit to the manufacturer $2-3. Profit to the wholesaler $2-3. Profit to the reseller, $2-3. |

//the flash memory one is more expensive// So, how does the cheap one retain the image? |

Hey what's this? The smell of baking?? Since when has
COGS been a concern at the halfbakery? |
|
| |
Since [pashute] and [MechE] got into a dispute with their HMO
and lost the funding for the atypical neuroleptics that helped
keep their symptoms under control. |

Anyway, they'll do it in china for 20 cents a piece if
you buy 400,000. But you stand a 60% chance that it
will work and even be sold nicely, but by your
competitor - who happens to be the same aforementioned Chinese company. |

Electroconvulsive therapy. |
|
| |
Your chosen microcontroller is nowhere near powerful enough for any
kind of image acquisition, processing, storage, or display. It would be
more suitable for a meat thermometer or kitchen timer. |
|
| |
Most display technologies require power to continue displaying an
image. Electrophoretic displays (e-paper) don't, but they don't have
good (or usually any) color reproduction. |

How are you going to make an optical system even 10 times as thick as
a business card, even if you're comparing it to other electronic
business cards (like the ones engineers design to stand out from other
job applicants, which are up to about 2 mm thick)? |
