fl@C@So, I have been testing and experimenting with the filters, etc.. trying to get a spectra from a sample of tap water using a makeshift setup... It works, I was able to get a faint sign of progress.. Enough for me to go on anyway.. Here's some shots of my tests..
Here's the first run...Yes...those are legos providing the height for some of the optics.. :) (Images of the spectra are down further... )
Another angle..
Here's a shot of the second round... That's the sample in the middle that's so bright..
Everything looks so cool under laser light...
Not much, I know... but this was taken with my cellphone camera by hand...the color didn't come out well and the full lines aren't showing in these for some reason..but you could clearly see the red when the sample was in front...
I've been researching more imaging devices...and I'm probably going with a linear ccd or a MEMS micro spectrometer like the hamamatsu C12666MA....
And some other things that have been going on...
Motors for the lens assembly...
The display and interface micro...
A test print of the newer design...

It's funny.. I had a rostock 3d printer that I had built and used previously...but maintenance on it was really getting to be too much for practical purposes.. So I bought one of the DaVinci printers for this project... I haven't regretted it.. The filament situation is unfortunate but I have to say...I have not had a single problem with it.. none.. and the prints always come out great... The texture on these is mostly a result of the print quality I chose while prototyping these parts.. :)
