Tracking with solar cells "might work" somehow, but isn´t very precise. Due to the high concentration of a parabolic dish you will need a very precise and 2 axis tracking.You can build a 1 or 2 axis tracking device with some LEDs and some microcontroller (aka arduino or alike). Check this site for more info:http://www.redrok.com/Site itself is indeed awful, but the most complete collection of ideas and solutions regarding solar energy I found yet.

I would recommend to get some sheets of (black) photo carton from an office or art supplies store. Not that expensive, bendable and available in different colors and gradients. Those have a matte finish so you don´t have to deal with glares from lighting sources or flash. Easy to fix with tape or clamps.Use some stabilizing fixture for your camera (tripod if you have one, zip lock bag halfways filled with rice placed on a flat surface also works fine [and on the cheap] as a camera stabilizer, even for macro photos).If done so, you can experiment with camera parameters and lighting sources. Check what parameters the All-Auto-Mode shows (aperture, exposure time), take those as reference. Higher aperture (aperture more closed) allows for sharper images / better depth of focus, but needs longer exposure time (Av-Mode). But until your camera won´t move, you don´t have to worry about that and can take sharp images even in low lighting situations. Cable trigger or self-timer can further help to prevent any camera shaking. You can still use auto-focus unless your object and background are pretty low-contrast and/or dark.If Av-Mode results in over- or underexposed photos, try all manual mode and adjust exposure time until you get the results you were looking for.Bending the photo carton behind the object allows for a nice and seamless bg gradient.Hope this was helpful, Regards
I make the spiral notebooks at work - punching bookblocks and binding the spiral wire - try using a embossing heat gun or even a hairdryer will help to remove the labels . We insert the books in diecut cardstock boxes for shipping. This is a good idea.

Glad you found it useful :) Thx for your comment!
Thank you for this post of such good advice on being prepared and the logical areas that need flashlights. A possible emergency this morning, brought me to a basket of 7 older flashlights, wrong replacement batteries, and a new LED one with no bulb.

Thanks for letting me know, I hope you will like the result!
PULL CORD ON DIMMER SWITCH
Rare Earth Magnet in a Bottle
Sticking with imerrymarys and WalkerD1s comments. Nice one!If you would attach a little bar to both ends of the cord you should be able to turn the lights on, off and dim precisely with a flick of the wrist. No need to grasp for the other end of the cord.For keeping the cord to the knob just hotglue a mason jar lid or alike to the knob, but I think you had that idea by yourself already.
