Slightly tweaked "New Standard Scanner" build

Slightly tweaked "New Standard Scanner" build

I'm posting this in the hope that it will be of benefit to others building their own scanners. Here's a bunch of of construction photos:

It's essentially the New Standard Scanner build after having also read Clemd973's New Standard build notes. Variations are as follows:
  • Top piece of column slots onto bottom piece (lots of drilling and chiselling - see http://www.flickr.com/photos/tserong/78 ... 1235755228)
  • An unbelievable amount of time was spent sanding and painting everything. If you're going to do this, do it *before* assembling the base, or you'll spend a lot of time with masking tape on the drawer slides :-/
  • Camera mounts are both towards the back, rather than one towards the back and one towards the front. More visually balanced. They're still basically centered though (one is on the near hole of the mounting bracket, one on the far hole, so they're pretty much centered to within 1cm or so of each other).
The cameras are Canon A480s I picked up a year ago, specifically because they were known to work with CHDK. They're both powered from cheap knockoff (i.e. non-Canon-branded) 3.15v mains adapters. I was going to splice those into the shutter release switch, but to my intense annoyance that's not enough voltage for a trigger, so I've got a separate 4.5v 1amp wall wart wired into a push button and thence to two USB cables. It's a bit less elegant than it could have been, but seems to work fine so far.

Total cost was something like AUD $300-400, with about half of that being the cameras. Note that if you're in Australia, you probably won't find keyboard drawer slides and column slides in large hardware stores (Bunnings/Mitre 10), so may instead have to visit a more specialist architectural fittings store for those pieces. I also couldn't find wing bolts to mount the cameras, so substituted short 1/4" bolts and packed them out with a nut each.

Geez... that might be the nicest finish I've seen on a New Standard in a long time. Congratulations, and thanks for going through the effort of coming back here and sharing it with us.

My pleasure, and thank you! (although, I can't really take credit for the finish myself - my wife is much handier with a spray can).

In related news, I just had that "OMG OMG OMG this is so cool!" moment of scanning something, cleaning it up (Scan Tailor), and OCRing it (tesseract), and having it mostly work. So my thanks to you for kicking this whole thing off :)
