The medium waterproof box (available from Adafruit.com in three sizes) turned out to be perfect.  They're transparent so I can measure the light levels (with a bit of adjustment of course), and since they're air tight, water proof and generally indestructible feeling, I don't have to worry about the LIPO battery shorting and burning the fridge down and robbing me of my diet Coke fix.]]> electronics https://pinboard.in/ https://pinboard.in/u:mlednor/b:48fb22e867b0/ 2011-02-15T21:49:59+00:00 http://aeroquad.com/ mlednor arduino electronics diy https://instapaper.com/ https://pinboard.in/u:mlednor/b:803b6271c52d/ 2010-02-13T11:39:00+00:00 http://todbot.com/blog/2010/01/02/momentary-button-as-onoff-toggle-using-555/ mlednorelectronics https://pinboard.in/ https://pinboard.in/u:mlednor/b:3d6ec860cb40/
