Im shrinking my animatronic bat ear setup down.. to possum head size maybe..... you can see the size difrance

arduio controlled ears? i have wanted to do the same thing for awhile now and i have an assload of RF modules and a few cheap ($6) bluetooth to RS232 adapters i sorta want to make an arduino/microservo controlled cat ears controlled by my phone
tho i might use an attiny 25 to cut back on the jitters caused by the arduino server library
tho i hate ACR C >_>

well yes but the current servo controller library only allows 180 steps per rotation when most servos can do 512 or as high as 16 bit for digital servos (65,535 steps) this allows you to modulate the speed (like a stepper motor in a CNC) so it does not do the physical jitter when doing rotation at less than the max speed of the motor (servo.write(pos=pos+0.1); instead of Servo.write(15); for a simple example of 5x slower movment will jump every 1* when the angle gets above 0.5 instead of slowly moving to 1*)
no i dont think they make those ... but to send 3.3v in to an xbee from 5V you only need 2 resistors
to receive from an xbee you need a transistor to bring the voltage up to 5V ... that can be done with this i made awhile ago http://www.furaffinity.net/view/7810959/ tho it does work better with R3 being just 1k ohm i later found out
BUT i do believe the arduino will take 3.3v without a transistor pullup ... you might need a small pull up resistor tho im not entirely sure ... but the xbee will not so you need the 2 resistor downshift for sure
i have 2 dead xbees from not pulling the voltage down on them XD
