What is the best lighting for a variety of applications for a “Beta”?

What is the best lighting for a variety of applications for a “Beta”?

San Francisco’s hackerspace Noisebridge just transferred one of their two Bookscanners to Oakland, CA’s Sudo Room hackerspace. I believe this kit was what Daniel Reetz called in this video a “Beta” prior to marketing the Archivist.

Here are some photos of our “Beta”:

There seems to be a tremendous amount of discussion on lighting on this list which must have resulted in some solid recommendations. At the Sudo Room, we are expecting that over time, different cameras will be used for different types of digital book production with this rig.

Possibly not always using cameras you recommend like the Canon PowerShot ELPH 160, what is the best lighting for a variety of book scanning applications?

THANKS!!!

That scanner is a 'hackerspace' model. You can tell because of the all-plywood construction including a plywood handlebar. If you want to upgrade the lighting for that scanner, there are two threads you can pull.

First, you can buy high quality LEDs rather than the lights you bought for it. SORAA 00919 is the recommended LED light bulb. You will need optics (for spreading the light), fixtures, a mounting plate, and a 12v power source to make it all work. Take a look at the Archivist descriptions here:

http://diybookscanner.org/archivist/ind ... age_id=267
http://diybookscanner.org/archivist/ind ... age_id=317

If you have specific questions I am happy to answer them. If you want to know how to get a particular part, let me know and I can either point you at a supplier or quote you a price.

Second, you can move the lights further away from the platen. Because of various design constraints, Daniel put the lights closer to the platen than is ideal on that model. For later models (like Daniel's Archivist design), the lights were been moved further away to reduce glare and hot spots. You want to reproduce this in some way. So just build a simple frame you can set on top of the scanner to lift the lights. There is a mathematical way to find the minimum distance, but it might be easiest just to do it empirically, pulling the lights away and taking sample photos until you see that there is no reflected light source.

Best of luck on your project.

Hi again Jonathon,
I am trying to get us to scanning ASAP. Could I purchase from you all the parts including lights, sockets, wiring, mounting bracket, jack and power supply?

Do you think the entire lighting system of the “quill” could be easily mounted on top of our 'hackerspace' model? Does that solve the spacing problem? Since “The lighting system on the Archivist…excels at putting light only where it needs to be,” could our 'hackerspace' model benefit from that?

How much would it cost to buy that entire piece?

Any reduced pricing or donations for the Oakland Sudo Room is needed.

Jacques
