I did (a year ago). See a second half of the page:

I've tried many different illuminators (including Verilux), but mine (LightWedge based) is absolutely the best! I'm using it almost every night.
The battery I use (GameBoy Advanced) is perfect. The charge lasts for about 3 Sony Redaer charges (several weeks). Current stabilization is a must. To be short, I believe my design is almost perfect (at least to me). The battery/electronics box on a clip is pretty convinient.
If you are thinking about commercial device, I think there is a better technology, but very hard to make it without special equipment. A plastic sheet with 10 micron scratches (triangular), seprated by 100 micron gaps. This design perfectly direct light to the page at the same time being transparent. In contrast to LightWedge, the thickness of the plate can be thin. This technology is used in some frontlight illumination displays. I was not able to get one to try.
I would pay for good illuminator (like mine, or the one described) as much as $200. Night reading for some people is 90% of reading (like me or my wife).
