Ok, I had a bit of time last night and got a basic lashup working. You can see the data on Pachube here: https://pachube.com/feeds/29101
The code still needs some work to be suitable for public viewing.

Re: Serial processing code? Patchube?
Yes, it's Python. I'm writing it on OS X, but will test it on Ubuntu and Windows 7 as well. Should be no problem to use it across operating systems.

Re: Serial processing code? Patchube?
Nothing for now. :-) I've got a simple class written that pulls the data from the serial port and logs it to a CSV file. The next bit that is still being worked on is to take that second by second data and roll it up for pushing to Pachube on a longer interval...every 5 minutes or whatever. I just h...

Suggestions for next rev
A few of suggestions for the next rev of the board... Bring the power lines out to a header (pins on the existing serial header?) so that the board can be more easily powered by something other than the batteries. I've got a CP2012 based USB-UART adapter I'm going to be using with the GC kit to get ...

Re: Serial processing code? Patchube?
It's a pretty simple XML format. Here's the API quickstart: http://api.pachube.com/quickstart/ I'm hoping to take a stab at this next week, but I may wind up buried like this week... As far as changing the firmware, I don't know of anything specific to change. The various modes (slow, fast, etc) wil...

Re: Why the preference of the SBM-20?
There are some very small GM tubes out there. The SBM-10 is pretty small and may be a good choice for an Altoids build.

Serial processing code? Patchube?
Hi. Unless you know of some existing code for processing the serial messages, I'm going to be writing a script to take the serial output and pump the data into Patchube. I'll also probably modularize it to write out to CSV or MySQL or somesuch. I'm going to be deploying this GC kit as a permanent en...

Re: Why the preference of the SBM-20?
Altoids tin will be a bit tough, but there are some small tubes out there. Be sure to check the specs before you buy, though. Some of the small ones (like the SI-3BG are not very sensitive). May of the US geiger tubes operate at around 900V, so you'll probably want to focus on the Russian tubes as m...

Re: CPM to uSv/h conversion
Ok, I'll check those out as well. I've got a PM1621 which is reading a bit lower (difference 0.02 uSv/h) than the SBM-20 in the GC kit. The PM1621 is shielded from betas, which is probably making the difference. I'll try to hack up a beta shield for the GC kit and see what it reads then. Nice kit, b...

CPM to uSv/h conversion
Jeff, how did you arrive at 57 for the conversion factor for CPM to uSv/h for the SBM-20? I've seen other numbers such as 40 used other places...
Thanks.
