The ADS-WS1 is also finally back in stock.  Or it was - we need more 
base units built now, and that won't happen until next week.  We got 500 
of the outside sensor assemblies in on Monday, and between back orders 
and new orders this week we're down about 180 units already.  It's been 
a busy week.

Also, unsurprisingly, there's been a big surge of interest in Geiger 
counter interfacing.  Bob, can we get a standard for sending ionizing 
radiation levels in weather reports?
