Re: super leightweight, super cheap, uncomplicated book scan

This is why I decided against a foot pedal. I use one almost everyday in surgery for cautery and it forces you into uncomfortable positions when you are constantly needing to have one foot floating off the ground. After several hours it can give you a sore back. Our other cautery is activated direc...

Re: Apple iPad announced

I think what it comes down to and what gives me the chills is that with all the content control and DRM, I would not own an Apple product these days but the product (and Apple) would own me.

Lockable joints may be an idea. It might be even easier to get a 90° bracket and fix that with wing nuts. Plus the triangl...

Re: super leightweight, super cheap, uncomplicated book scan

Nice to find that you like it :-) I just did a timing test: removed the loop and measured the time from starting the script to exit. It's ten seconds to take two pictures and to be ready for the next. That's not superfast but ok for me. In theory, that's 720 pages per hour... This is for Powershot A...

super leightweight, super cheap, uncomplicated book scanner

I wanted to share my setup for my book scanner. It's super leightweight, super cheap and uncomplicated. IMHO the best thing about it is the method to hold down the pages. Power Supply: I use two Canon Powershot cameras which I power via two voltage regulators (LM350). Although the cameras have 4.3V ...
