Re: CHDK/SDM Remote button/settings autostart

Looks like this was more or less user error. Autostart uses the last run script. I had just re-installed CHDK on my card when I tried it, and I thought default.bas was the script that was always used when Autostart was enabled. I'm not 100% positive, but I don't think that's the case. It looks to me...

CHDK/SDM Remote button/settings autostart

I'm thinking this should already be covered somewhere, but I've done a bunch of Googling on this site and CHDK's and can't find the information I need. I've got a pair of Canon A480s. I've got CHDK installed/autobooting, using Spamsickle's grid, and using the the remote button script that's in the s...

Re: Lighting Specs

It may be that brightness ultimately does not matter, given the option on a solid rig to hold the camera shutters open for long times, but 278 lumens / 9W continuous lighting just doesn't seem bright enough -- isn't that less than the output of a single 40w incandescent bulb? Most of the rigs on th...

Lighting Specs

Found the spec/product sheets for the light rails I've been thinking about using. I haven't read the lighting threads in full to know how these lights compare to the ideal, but based on the test shots I think I'll be sticking with them.

Looks these generate 278 lumens.

Re: Has anyone looked at gPhoto2?

I've just been getting ready to dig into this myself, will be installing it into my Linux VM shortly. Have you seen Translucent's build which uses Gphoto?: http://www.diybookscanner.org/forum/viewtopic.php?f=1&t=495 I don't believe the perl-gtk app he mentions scripting is readily available though. ...

Lighting

Lighting is still a bit of a question mark. Right now I'm thinking about using this lightbar. I've got an inside connection on these from the manufacturer, so the price is right. That said, a bit more light wouldn't be bad - the shot below was taken at 1/25 of a second, which should be fine for this...

Camera Mounts

Machined 45 degree pieces of 80/20 extend from the two vertical bars for the camera mounts. Another flat piece is positioned there to provide the final resting place for the camera.

Temporary Sale offer for 80/20 Scanner

I just came across enough 80/20 extrusions to build a scanner that I would be willing to sell. See the scanner I've been building for my own personal use at this thread. . I'd be willing to deviate somewhat from this build, but not too much as I don't want to spend much time figuring out how to do t...

The Platen

While Railman's CNC router bearings look like they rock, the best price I found on ebay was $99 for the same thing. I also looked at 80/20's linear bearings - ordered these just to check them out, and wasn't that impressed - the primary sliding mechanism is just nylon which moves along the extruded ...

The Cradle

The cradle is one area where I veered from the other designs. The dimensions are the same as the other build (aside from using 3/4 inch plywood), but I wanted to take advantage of the sliding action that the new standard scanner uses to handle different sized book bindings, and I wanted to use somet...
