Look what the cat dragged in! Been off the forums for quite some time, had some medical problems and nonsense going on.
However, I've not shelved everything Arduino related- in fact, I spent a lot of time attempting to get Honeywell to buy in to producing the gas safety valve- which is arduino-cored. It's not a big deal, simply using MQ series gas sensors and TMP85 pressure sensors to monitor line pressure and environmental gas concentrations. If unsafe condition is found, de-energize the coil on a normally closed solenoid valve, located outside the home, cutting off supply and preventing disaster.. Suffice to say Honeywell passed on it. This is a project I have dreamed of for thirty years.. I survived a gas explosion which killed my parents when I was fifteen. I've named the project in memory of them (not myself), "The Bishop Valve". Though Honeywell passed, I have not given up and am not going to stop until the device is a reality.

On lighter notes, I'm also building a CNC router (second version, much learned from first design and problems therein) and a set of RGBW High-powered photography floodlights. Using TLC5940 and Arduino Pro Micro clones, they are perfect for the job. Each floodlight head has 10 watts each of RGB and 20 watts of White. Fifty watts of LEDs is a LOT of light, around 4000 lumens. I got a few bluetooth serial modules for a song a few months ago, so I am planning to slap those on for communications. Down the road, I may consider switching the power source to Lithium cells, or to use Ryobi rechargable tool batteries, as I have several...
Good to be back around 8)
