Does anyone know if someone manufactures something like this, or
manufactures an inexpensive (monochrome ok) touchscreen LCD display
(3x5" = okay) ? I am curious how expensive/difficult it would be to
build touchscreen notecards - just a "dumb" screen that you draw/write
on with a stylus and it holds the image in memory (kind of like an
etch-a-sketch). It would probably have 2 or 3 buttons - one to erase
it, one for "erase mode" - when you hold that down, pen input erases
instead of draws, possibly a 3rd button to "open image from sd". It
would have an SD slot to xfer images off of it (or possibly a mini-USB
plug to sync to computer). When you plug in a SD card you'd see a
sorted list of filenames on the SD card with a scrollbar. Scroll down
to the image you want and click on it to edit in the device. Basically
it would be a dedicated dumb digital input device, powered by a
lithium battery like in a motherboard, or small watch battery (like in
a laser pointer) or maybe a solar cell. The initial idea for these was
to use as 3x5" note cards for project planning (ie scrum development)
so the target price would be as cheap as possible so you could have a
bunch of them (50-100) at meetings. I'd be curious to hear people's
knowledge of any such products/components that could be used for
this...Thanks
