[Drosophila] Re: Dros Digest, Vol 55, Issue 9

[Slawek Bartoszewski]

Dear Sandra,

Please, check the page:

http://130.15.90.245/gfp_stereoscope.htm

The system is described by worm people. I tried to set it up.  My problem 
was that all the materials were US based, it took ages to import them 
through the ocean and some parts were missing.  They used a LED lamp and 
filters which are mounted inside the microscope.  I finally got the 
materials, but still had to change the current - an electrician made 
something very simple.  It didn't work for me, the bulb did not produce a 
single wave length light.  Maybe a simple extra filter would help or the 
current was too weak.  I admit I didn't have a good workshop who would help 
me.  You might try the same, it will be easier for you and not so expensive. 
I would be interested to know if you get it working.

Regards,
Slawek Bartoszewski.
