Here is my second try on a thread about connecting a scanner to the PSP.
But this time it is SERIAL!!!!!!!! (not that USB is not serial, neither that there are no USB > serial interfaces .)),
So, it would be a 5-10 USD scanner with a high enough resolution to scan a line of text!!!

just thought you are interested in Jeroen's page:.)

And yes,

... ADNS2610... the sensor has a tiny 18x18 CCD, which can be read out using the serial port (


SW:
the main idea would be to allow
- scanning text and
- storing it as image
- compressing it
- OCR
- dictionary.

Killer App:
you see a text written in a foreign lan (Ge) and decide to trynslate it.
yepp.

HW:
once we get this (or another sensor with higher res.) working,
I'll definitely make a nice tiny box with a 'short' serial cable to the PSP,
but first back to the roots:

ok, i made a test:
the Agilent sensor has a view of sthng like 0.5x0.5mm, which is quite few..
it would definitely require to replace the lens, which makes everything complicated.
Another issue is the speed of transfer: the SW provided
on that webpage allows very-very slow sliding of the mouse, otherwice the
scanned image becomes non-continuous. Hopefully there is a cure for this,
but the lense-problem....!?!?!
ciao!

A scanner is a fun idea, but I would go for some kind of pressure pad sooner. :) More varied amounts of fun for that.

These days, a mobile phone's camera would be a more efficient scanner.

What would you need that for? Isn't it enough if you can talk to the mobile phone somehow, to transfer data? Infra-red, WiFi or USB should be your options. USB would be great of course, for the phones that support it, but you'd have to get this USB OTG thing sussed. Infra-red would probably be easiest at the moment - there are some libraries out there that would be fairly easily ported and I suspect most phones support it. Of course it would also be slowest but hey.

Figuring out USB OTG would be the next best thing since WiFi was unraveled though, imho. It would also open the door to voice recognition for instance, like Talkman demonstrated, or connecting your real digital camera, phone and whatnot.

yepp, there was a day ...
..when a similar topic was started....

USB version locked:
http://forums.ps2dev.org/viewtopic.php?t=4096&highlight=scanner

WiFi version attacked
http://forums.ps2dev.org/viewtopic.php?t=4094&highlight=mic+input
(from post nr. 6 and so on)

you see, this is why we are at the Serial version now...
otherwise, without discouraging people, maybe..
maybe we would already be somehwere else.. as the honda project.
