My wife and I gave my Mom a glass sculpture for Christmas. When my Mom opened it my brother piped up with "RadBear (well he actually said my name) could build you a light box!". He said this because as someone who collects glass I've built a couple of light boxes to display my collection.
However, since I'm not a carpenter some of my light boxes aren't pretty and since this is for Mom it has to look good. So I decided to reuse a wooden box I picked up in a thrift store as the basis for the project. This way Mom won't feel obligated to keep a piece of crap in her very nice home.
This is what I made my light box out of:
* A wooden box with a hinged lid
* 1 piece of glass
* 1 piece of mirror (not pictured)
* 1 piece of cardboard
* 1 white LED
* 1 AAA battery holder
* 1 switch
* 2 Philips head screws
* Scrap wood (I used a chopstick)
* Metal duct repair tape
* E-6000 (or your favorite permanent adhesive)
I plan to use frosted glass spray paint to help diffuse the light, however with the current weather conditions this will have to wait a few months.
The mirror is not pictured as it was added after I finished the project. My wife suggested this addition and it is yet another reason why she is a kick ass human being.
