Great, another month of troubleshooting.

Ouch.  Not funny.

It's probably not as fast as Yaho, but has a lot more class.

Vector 2x.  Serial clock, data deal.

There is just an extra bit-banged serial port/max232 for devices
such as a GPS.  I've seen GPS as low as $150 but I think the ones
that have RS232 are about $300.  I've just made provision for
a serial port and power so I can have this option in the future.

This made with 4 simple mercury tilt switches at about 20 degree.
Got them from mouser.  Didn't see any need for the variable

Only thin crust.  Working on thick algorthms.  Grease
detection and removal software already complete.
