  • Also, it might be useful to either normalize the readings to the specific emission spectra of the white led or even use an RGB LED and string out the measurements over a time span with each spectrum range being read, or at least saved in memory from the register while that spectrum is being emitted. I know I could do this myself, but I figured other people might want to know that too. The code, as it is, reads all ranges in one function call, from my understanding of it. Maybe ill try to work this out and share it somewhere. I imagine this would do alot for the precision of the readings. This might even allow this sensor to do some readings related to atomic absorption spectroscopy, which is extremely powerful. Thanks again, this has actually inspired me to get back to this idea. Now I just need this sensor to be available again haha.

  • Not at all usurped, I am happy I was pointing in the right direction. Thanks for the response. I am definitely picking one of these up, see if I can try to pull out the the kind of data I had envisioned.

    By the way, thanks for a great site, store, and resource. This has always been my favorite site, due to the quality of your products and the range of depth of your tutorials. I recently used the eagle tutorials on here to design my very first PCB, a VNH5019 Motor Driver board. Not too pretty, but it handles 10-20 amps so I am proud. So thank you.

  • Really this is a spectrophotometer. Great job by the way guys.

    I was trying to make this exact thing for like 2 years. Unfortunately when I started I knew exactly nothing about electronics. The whole reason I got into electronics was because I had the idea for a cheap photospectrometer to be used in water quality analysis. Damn, o well. Bravo. I was even planning on using these AMS sensors for the first iteration after I saw it on mouser and emailed AMS about it, then once you guys released your sparkx spectral sensors and I saw another cheap and easy spectrophotemeter in the wild I knew Id never catch up. You guys should make a water proof container that allows water analysis, although the light source has to be much bigger.

    The applications of this in water chemistry and water quality are huge, although the precision would have to be bumped up. AMS has a couple other options, which of course make it much more complicated. Distributed sensor networks analyzing our water distribution networks, or wastewater, or streams and rivers for water quality would be BIG government contract style money. That market is still there, but im still relatively useless in electronics. Water is my thing.


    The video shows an amazing use for this product. If I could afford it, I would be pulling as much data out of the sky as I could. I mean satellites, but still. It is just amazing to be able to pull data off a small box flying above the atmosphere at many thousands of miles per hour. I wonder if you could do even more with the blade RF. I'd love to figure this all out. Hope somebody else who owns one can figure this out and maybe put up a tutorial here.

    I am offering my services to sparkfun if they want to send me one of these or the blades. I'll write out a detailed illustrated tutorial and make a video for you guys. I'll even send it back if I am unable to produce any results worth sharing. Maybe I can just assist one of your "hackers in residence" no need to pay me and I want no ownership of produced material. Just the experience.

No public wish lists :(
