Please let us know the size of tubing required to extend the system?
I initially had the same issue with the Crowduino board it was a com port issue needed to be set to com 3. Read specs on board and overrode to reset as a Arduino Duemilanove Schematic seemed to work, will keep testing.
You guys have any more documentation on the shield that comes with this kit -- the various specs on the outputs etc. I recently bought this kit and was wondering on the shield's capabilities besides the water sensors, four valves and pump activation. It seems to have 5 alternate relay break outs but I need to know if these are the solenoid valves using these relays, and I have an extra relay or if all are accounted for: ie the pump relay, and the 4 solenoids. Also want to know which of the analog pins I can use and which are used. Looked everywhere on the elecrow website and I couldn't find the specs. Thanks for the help. It would help as well to include documentation on data collection and logging as it seems that a lot of users are interested in this aspect too.

This is super cool! You should try and use a digital shutter such as an old LCD display instead of a manual one. You'd just need to rip the back light off and send the light strait through that way you can try out tons of different shutter/ cutter styles and be able to instantly stop the cutting based on the display brightness. It might be too much shade but you never know...

So through out the process the vapor escapes the food and fills the desiccant enriched jar, the second vacuuming is meant to make sure the vapor goes away and that the water in the vapor inside does not erode your seal on your jar. As for your other question, yeah I just tried two different ways of doing it.
