So after a wonderfully terrifying dream last night, I have come to the realization that I have been a bit too cavalier with safety.

Hydrogen is an extremely flammable gas that is tasteless, odorless, and colorless!

So I have decided that I will be setting up a monitoring and emergency shutdown system. I plan on integrating several hydrogen gas sensors that I found on Sparkfun (HERE) along with microcontroller.

Microcontroller integration also allows for added functionality from monitoring gas levels, power output, and temperature. It will also allow for great gas flow control, by giving the user access to electronically controlled gas solenoid valves.

But the primary dilemma in using a microcontroller, is access to a computer. Since this project is being designed to use in places without access to power let alone computers.

So..... What to do?....

I could get the coding packaged up and ready then the controller could be flashed, but this may not work depending on environmental factors, plus what if there is a fault, and no one can repair the code.....

I could integrate a microcontroller with a simple LCD screen and a keyboard, but the tech may not be easily sources, plus it's just adding to the cost.

After trolling around for a few hours, looking at several different options, and thinking about several work arounds. I decided to see what the Hackaday users have done to get a low power small package solutions. Then there it was in front of my face...... LightBlue Bean. It meets all or the requirements; small, low power, easy to program, plenty of room for sensors, economical, plus phone integration over Bluetooth.

This might strike you as odd, but Africa has more cellphone users than North America or Europe. Asia is the fastest growing cellular market by some accounts. Many parts of Asia and Africa are home to some of the world's most underdeveloped regions.

So looks like LightBlue Bean it will be.

If someone has one of these just floating around they want to throw my way, it'd be appreciated... Not saying any names, but heard these are being handed out.......
