Hi George,
I'm copying publiclab-northeast where we've started to pool some Mainers.
see http://publiclab.org/wiki/maine to read about some of the interested local parties and add your beloved area of interest, hopefully???? http://publiclab.org/wiki/maine
I may create a Maine email thread to introduce everyone on the publiclab-northeast group. Please join that.
let me know how i can help!
Liz

I am proud to serve on the Host Committee for 596 Acres' upcoming benefit on October 2. 596 Acres has helped neighbors create 25 new formal community-managed open spaces in NYC -- and counting! Help us keep opening up those fences by attending Mapping Matters on October 2, 2014 in DUMBO. Details here.

Liz,
I am interested in meeting people doing water instrumentation in Maine. Please provide info.

Don,
Are there separate sensors boards?

Hi George,--
Hah! Sorry, I apparently replied to everyone I thought was relevant to your question except for you, somehow :)
Below is my response to your earlier email -- and I've now placed us on the 'waterquality' mailing list ...
Feel free to follow up with any additional questions ...
Cheers!Don

Hi George,
Great that you dug in and opened up the files in gEDA! I believe the version of the Riffle that you're looking at is actually an earlier version of the device based on a different microprocessor (an ARM K20). That design is actually more powerful, and will ultimately be cheaper to produce, than our current version. In the meantime, we've been working on an Arduino UNO-compatible version (based on an Atmel 328p chip), which is located here:
This (most recent) version requires using Eagle CAD to view the files.
We went with the Atmel design for the time being just to make development on the device as accessible as possible for as many folks as possible (given the popularity of the UNO). But the ARM-based design is still very much viable, and ultimately we'd like to return to, or at least offer it in parallel. So, if you have some familiarity the requisite tools, it'd be great to have your help in pushing that branch of development forward!
In case you'd like to have the ARM-based device assembled, I'm including Ben Gamari on this thread, who is the designer of the device, and may actually have an assembled prototype for you to purchase.
If you'd like instead to start using the Atmel version, we're planning on starting to distribute an 'alpha' version of the hardware in the next few weeks. The initial cost for the board, FTDI cable, and conductivity + temp + light sensor will probably be around $150 at this stage, with the hope that as we scale up in production, and optimize our workflow, the cost will come down.
Would love to discuss ideas around measuring turbidity ... we've got a basic way of trying to do that on the 'latest' board, and it'd be great to hear your thoughts ...
Let's continue this conversation on the plots-waterquality list (included above) in order that I'm not spamming the main list with further arcane details :)
Cheers!D

Don,
I will wait and let someone else do the assembly work!! Looked at the schematics
and artwork. With my gEDA tools, pcb version 20110918, I get errors when performing
the "Design Rules Check" function. Same for you or is it a non-issue?
Approx cost?
Firmware?
Are the LEDS and color sensor intended to do turbidity? If so do I need 2 sets?

HI George!--
Thanks for the interest. There will soon (in the next few weeks) be assembled boards available for purchase, I believe (exciting!) -- at least on an 'alpha tester' basis :) For reference, the latest version of the hardware (and associated software) is being stored here:
If you'd like to order the PCBs and build the device yourself, let me know if there's anything that's not clear in the Eagle files -- still need to catch up with all the documentation! And please feel free to send along any other questions -- answering them will be useful for everyone else who may have similar questions here on the lists, too :)
Cheers!Don

I would like to get started with RIFFLE. Are there assembled boards or do I
purchase the PCB & components individually? The riffle-master.zip contains
hardware related files. Is there a corresponding software package.

George,
We will be trying out the Riffle and discussing the next development steps at LEAFFEST on September 13-14. It's a 4-5 hour drive for you, but you are welcome to camp in the yard and join the fun.
Chris
