I saw an Instructable for these neat LED-lighted jars some time ago - I thought it would be cool to make a couple to leave in my room. It’s a very simple hack - you gut a solar garden lamp, replace the LED if desired, and then place the parts into the lid of a large-mouth jar. Then simply do something to diffuse the light emitted - I used a glass frosting paint but you could just as easily add in a sheet of tracing paper or the like. I ended up making four - they turned out very nice, and I gave two away at the Phoenix DIY Meeting. Full Flickr photoset.

Really, there weren't many construction photos to take, but here's the garden lamp guts being epoxied to the jar lids.
