Digital Camera Spectroscope
Intro: Digital Camera Spectroscope
This simple mod allows the slide to be mounted to most cell phones, turning them into digital spectrometers.
How-To
How-To
STEP 1: Salvage Springs From an Old Floppy Disk
You need four floppy disk ( 3"1/2).
STEP 2: Modify Springs
With a pince, modify springs to get arms parallel. Do it for each spring
STEP 3: Use an Old Photo Slide
open it.
STEP 4: Soldering Springs
with a candle ( or something else ) turn springs very hot ( red ), and quickly solder it on the slide.
put glue on each spring ( and in all corners )
put glue on each spring ( and in all corners )
STEP 5: Side2
close the slide with the other part. Press it for 3 seconds.
STEP 6: Rubber Band
take an old mouse pad and cut four parts ( 1cm x 4.5cm )
STEP 7: Glue Rubber
put one rubber part under spring. put glue. put the second part on it and press hardly for 5 seconds.
do it again.
do it again.
STEP 8: Finish !!!
now you finish it ...
STEP 9: Diffraction Grating Slide
put a diffraction grating slide in front of it ( glue or other ).
STEP 10: Be Mounted to Most Cell Phones
you can use it on most cell phones
STEP 11: Make Spectro Picture
Now you can make this kind of picture

I did not read the bottom of the page .......... :o/
So yes, in that case, 5 euros is a better price ! =o]

About "RGB filter", I wanted to mean "Color filter mosaic" or "color filter array" of course : Each pixel of the sensor having a different color filter (R, G or B).
I know that the human eye uses a similar method.
But like I explained in my next comment (the one with bold writings), if I said that, it's because I've personally noticed that none of my cheap DC or Camcorder were able to capture spectra correctly (ie, captured spectra were less complete than when I watched them with my nude eyes).
For instance, a captured spectrum of the direct sun-light (which is supposed to display some absorption lines) had a giant hole between one or several narrow B strips, and an incomplete G band, etc ... It looked like the spectrum of a fluorescent lamp.
My interpretation of this phenomenon :
- R, G & B filters used by the sensors of my DC and Camcorder are of a too bad quality (narrow B filter, composite G filter, and large R filter), and I've wrongfully generalized by saying that color sensors were unable to capture complete spectra ...
Then, DoreJC sent me a private message and gave me a link to a French site showing some very complete and perfect spectra captured with a simple webcam. And that's how I went to the conclusion that my cheap DC and camcorder must be really terrible ...

J'ai eu votre message.
About my previous comment, I wrote that because I failed to film or photograph a full spectrum using my digital camera (Kodak C310) or my camcorder (Samsung VP-D371).
Au sujet de mon prEcEdent commentaire, j'ai Ecris cela parce que je ne suis pas parvenu A photographier un spectre complet avec mon APN (Kodak C310) ou mon camescope (Samsung VP-D371).
So I guess that some cheap DC and Camcorder will not make it ... unless we want inaccurate spectrum ...
Donc je suppose que certain APN et Camescopes bon marchE sont A dEconseiller ... A moins de vouloir des spectres incomplets ...
Just for reference, could you, please, tell us what device you tested it on ?
Juste pour rEfErence, auriez-vous, s'il vous plait, l'amabilitE de bien vouloir nous indiquer les appareils sur lesquels vous avez rEalisE vos tests ?
