Make a simple through-hole Printed Circuit Board for the Coqui <$5 water conductivity sensor.
I don't really know how to do circuit layout but I attempted on Upverter.com:
I'm tempted to just order this and see if it works. It's like the one Katie and I did on a blank PCB:
But I'd love it if someone checked my work.
Let more people make Coquis simply and cheaply!

This looks really good!
The first time i have ever found a tree frog in my house was at the LEAFFEST where the Coqui was built, tested, and designed for PCB.
Clearly not a coincidence.
I hadn't heard of upverter.
Adafruit has been pushing Eagle software, which is non-libre and has a cost. I've been seeing a lot of Eagle usage in the maker community, mostly, I suspect, due to the influence of Adafruit.
Upverter is nice, Eagle is just as user-friendly as a CAD software from the 80's is expected to be... We should find someone to give us all a KiCAD lesson:
I'm fully in support of distributing proto-boarded Coqui's over circuit boards, mainly because we may need to add parts/change the resistor and capacitor values. I'm not sure much is gained by soldering everything down.
Recently bumped into this:
Haven't looked much into it, but the front page shows there are some collaboration tools as part of the design process.
Will Macfarlane (@wmacfarl) kept working on this and has a more compact version which we're not quite sure works. There may be a problem with the 555s themselves, but I like how compact this is. It doesn't have the features of Don's more complex version here: http://publiclab.org/notes/donblair/10-18-2014/coqui-pcb-audio-jack but Parts and Crafts has been using it. I'll upload a photo soon.
PCB on the right, of course.
