My RPi sitting in a mass of power, video and sensor tentacles (the coil is the 15' cat5e run to the PIR). I built a cardboard box for the PIR sensor for god only knows what reason
and have it perched on the chromecast box so the screensaver will kick in while I'm working with my office chair in its usual location ("under the cone of detection"). I can wake the 'Pi by just leaning towards it by about a foot and it "sees" me when I enter my office from either the hall or the door out to the deck.
This will work almost perfectly for what I wanted - the only thing missing is a true low power standby state for the monitor. The code I found on Git-Hub doesn't work as advertised, but I'm hoping correspondence with the author may reveal an undisclosed dependency, or perhaps a transcription error when he loaded his archive, or Idiot Operator error, or something. I could live without it, but standby consumes only 1 watt, while a back-lit black screen is closer to 100 watts, so there is some motivation to "go green" here if possible.
Ordered another pair of temperature sensors and intend to expand my temperature logger to four channels, so I can monitor the beer and air temperature inside my keezer, plus the beer temperatures in my ferm fridge and carbonation/cold conditioning fridge. The cost of the sensors is so cheap, and it's so easy to expand the database and supporting code it'd be criminal not to add them
fwiw, I haven't found any obvious hardware or software conflicts between what I've been playing with and where RPints is apparently heading...
Cheers!
