P3D My own lighted radex - Alan Lewis is great, but...

["Dana Nibby" <dnibby@xxxxxxxxxxx>]

Had fun looking through Alan Lewis' stereophotography projects site; 
Liked his lighted radex design but, unfortunately, I don't have access 
to skill saws and other expensive tools.

[my collection of tools = a soldering iron, a few screwdrivers,
 and a hammer]

Went to radio shack and purchased their "enclosed battery holder" (2 
AAs) and a ~2.40 volt Xenon bulb. ( ~ $3.50 total). 

I found that the battery holder itself could be super-glued quite easily 
to the diffusers on the radex, and a bulb, pointing downwards, fit quite 
nicely - in the center, between the slide tray and the battery holder. 
Had to solder directly to the bulb because I couldn't find a bulb holder 
which fit (super-glued the bulb as well). Add a mini-slide-switch - or 
just twist the last two remaining wires together - and voila! Lighted 
viewer. 

I was a bit worried about there being no back enclosure, but it works 
just fine. A little ugly, with exposed wires and such, but I think it 
looks quite cool. My room-mate told me it looked like night-vision 
goggles.

So, for ~ $6.75 ($3.25 for the radex + $3.50 in components), you too can 
have a lighted radex viewer.

I'll try to take some photos of it (wish I had a digital camera) and put 
the plans for it on the web somewhere. Any cheap, easy modifications are 
welcome.
