[VicPiMakers Projects] Projects Digest, Vol 6, Issue 5

[George Bowden]

A couple of corrections... multiplying  a minute of microseconds requires
the microseconds to be declared as 60000000ULL   yes, thats ULL at the end,
Unsigned Long Long.  I found this error when I went above 20 minutes sleep.
Also , concatenation of strings in php is with the period, not the plus
sign.  I should put all this on github so that my corrections are available.

Michelle, I am defrosting a turkey slowly inside a closed ice chest on my
balcony.  I have a temperature sensor on the turkey that warns me when it
has risen to 3 degrees Celsius, meaning it is thawed and time to cook it.
I'm not heating it in the ice chest... ambient daytime warmth just seeps in
slowly through the walls of the ice chest to melt the turkey slowly.  The
turkey is cooking in the kitchen now.
