PARTS LIST

Parachute Timer Notes:
U2 (PIC16C505) should be socketed, all others mount directly to the PCB.
U4 (the surface mounted part) is mounted oriented UPSIDE DOWN. In other 
words, the top of the chip (pins 1 and 14) should point towards the 
BOTTOM edge of the board.

The ADXL150 and the MAXIM part (MAX953) can be obtained as FREE SAMPLES 
from the web by browsing to www.analogdevices.com and www.maxim-ic.com 
and asking for them.

NOTE: The schematic shows a 3 terminal device for power, but the parts 
list is a 2 terminal device (lighter weight).  If you use my artwork, 
use a 3 terminal part.  Sorry, I don't have the Digikey P/N handy for 
these.
