Re: [DIYbio] Re: Does Anyone Know Of A Submersible Arduino/RaspberryPI Compatible Spectrometer?

Hi folks,

I thought I'll chip in as well as I am struggling with a similar project. I am building a closed bioreactor to grow algae with, and that can essentially do what you need it to: monitor nutrients/spectral characteristics of a body of water. I helped design a prototype a few years ago, there are instructables for that one here: http://www.instructables.com/id/Biomonstaaar/

At the moment I am trying to come up with a new design that allows for more automation but being a biologist my electronics knowledge is limited. At the moment I am hooking up demo sensors to an arduino board and using the instrumentino package (https://github.com/yoelk/instrumentino ) on a Pi to log and graph all the data but the system does not work too well.

So if you do come up with a design that work and could keep me posted I would be utterly grateful. Also, if you feel like looking into why I can't get my own system working that would be amazing.

Let me know if you find any of this useful.

Cheers,
Mate

It's important to be as objective as possible when defining
requirements and when choosing appropriate tools to handle those
requirements (including the reasons behind those early requirements),
i.e. without bias.  It will make any project much more successful both
short and long term.   Most of the project failures I've seen could be
traced back to arbitrary decisions in the requirements or early design
process, not in the later implementation.
