and step speed.
One final note if you do
use this program/circuit on
the Stamp CI board (like we
did with the neon sign): You
need to cut the traces that
connect P12-P14 to the
output buffer. This will
prevent the buffer circuitry
from interfering with
sequence selection and the
RCTIME circuit.
HACKER’S HINT
built for trade shows. The neon part
was, of course, contracted out to a
sign shop. We took care of the control
by using a BS2p on a Stamp CI board
and a set of Opto- 22 relays. If you
happen to visit our Rocklin, CA office,
be sure to pop into the “Purple Room”
for a look at the sign. It uses a pretty
sophisticated program that includes
IR remote control of the sequence
If you’re into hacking store-bought products to make them your
own, and you like weird and wacky
items, you may want to be on the
lookout for the various “talking”
animals (fish, deer heads, etc.) that
have become popular at large
discount stores. The Parallax EFX
gang (John Barrowman, Ryan Clarke,
and me) bought a talking deer head
(about $100), gutted the electronics,
and then installed a Prop-1
controller and an AP- 8 audio player.
It took about 15 minutes to determine which motor did what (all run
at nine volts DC, and we used the
supply that came with the head to
power the Prop-1 and AP- 8). So, if
you want to have fun with your
friends and family, pop your own
voice into an AP- 8 and let your
favorite animal deliver the message!
Happy Valentine’s Day to all of
you that are romantically inclined,
and to all, Happy Stamping until we
meet again next month! In April,
we’ll be talking about a new Parallax
controller that is so powerful it will
make your head spin! NV
