I'm building scanner #3 & #4:
Book Scanner #3 will be a 2x camera, full platen build for robust, high-output books scanning, similar to my first 2 builds. I'm looking for a device that will power up LEDs when the camera trigger is fired, then shut-off the LEDs after each capture. The LEDS need to mount on a canopy from above instead of pointing directly at the platen like the cameras do.
Book Scanner #4 will be a minimalist-designed, iphone 4+ (or future iPod w/LED flash). I'm working on a dock-connector app that allows remote firing from the Macbook Pro. No on-rig displays for this build, ultra-thin materials, portable, collapsable, recyclable, and powered by a fold-out 55W solar blanket (pictured).--The solar-fold-out panel can lay outside on the deck and charge a new unibody Macbook Pro under full sunlight--fact. The Macbook can power the iPhone, and with an LED lighting option--or LED onboard the iPhone, I'm beginning to think I can scan books off-grid. We're really close to having less technology bulk with increased quality. That's primarily why I like Apple products with the applications of book scanning integration. Despite the latest rage and hype of the company, I personally believe they still focus on well-enginnered designs which could lend to how I build hardware that is low-fat and well made.
I have 1.5 years experience with household LEDs in my apartment but I really need to wrap my head around adequate lumens, unified color, power, and cost-effectiveness. I read some debate about lumens and color for LEDs. But I've also seen some improvements in the industry and some LEDs are inexpensive and powerful. What LEDs should I consider? -- If at all possible, I'm more inclined to buy USA-made.
Send me your facts, opinions and criticism. I'd like to hear every idea before embarking on my next builds.
