The Scary Terry board has been updated once again. The features
remain about the same, but we have added sturdier audio jacks that won't
get accidentally ripped off the board.
Scary Terry Audio Servo Driver Board
This circuit allows you to easily hook up audio to the
circuit board to drive a servo for animating the jaw of your prop.
Easily create a prop with that highly sought after animatronics effect.
Operates off of a 6 to 12VDC supply.
NOT JUST FOR DRIVING SERVO's ANYMORE!!! We have
included a ULN2003 chip that allows you to drive devices such as relays,
lamps, solenoids for pneumatics, etc. in sync with the sound you are
The 3.5mm (1/8" stereo) style audio jack allows you to
send input sound to the unit. It can driven by just about any CD player,
Tape Deck, MP3 player, etc. (audio cables are not included, but are
available below in our Accessory section). Use the 3.5mm (1/8" stereo)
output jack to connect up your amplifier or amplified speakers.
Switches allow you to choose the Left or Right channel
or both for the skull to follow. A passive mixer combines the two
channels when you use both, instead of just shorting them together.
Two header pins for easily attaching LED Audio Eyes so
that they flash in sync with the sound you are playing (LED Audio Eyes
are sold separately as an option). NEW OPTION - Have the LED's stay on
all the time or have them flash with the sound!
Easily select which capacitor is used for shaping the circuits response to sound.
Power LED shows you in a glance whether the circuit has power or not.
We also added the ability to drive the circuit using an
electret condesor microphone, which works well, but the sound out to
the speakers is quite low, so it may have limited use. It will require a
strong amplifier to be connected to it in order to hear what is being
said to through the microphone. Sorry about that! We tried, but we got
in too much of a hurry to get the boards done!
Board size: 3" x 2.4" and 1/2" high (without connections attached).
Some great dialog for your Scary Terry unit can be found at the hedstorm site.
There are Old Lady Skeleton clips, Rimshot Skeleton clips, Damien's Old
Guy clips, Jack & Dave Clips, and bunch of other great stuff!
Also, check out there Music CD's to add some great ambiance to your haunt. They can be found here.
Push Eject of the Halloweenforum.com has created an excellent video of
how he uses this circuit and an audio editing program to make the jaw
movement on his Bucky more accurate. Click here for the video.
