HI Robotmaker

sorry didnot see your post , But its still worth showing again . Ill look at the AN6884 Circuit , Is it much better ?

lower cost easy to use,SIP chip and can set it up mouth going in or out ,using 2 of them,on LM3914 OR LM3915 has 10 leds and only goes one way with 5 leds chip AN6884 can have them go in to center as sound is apply or reverse

@ndavid79 you can use the EZB analog port as a voltage monitor ,if no analog port left use a simple voltage comparator and output to digital port,witch is really the best way,because no sftware is needed to set the trip point,check the reply i made using IR sensor on digital port of this post for the circuit

COOL will have to try it out

@steve_c futurlec i think is in you area and thats where i get them under $2 each AN6884 CHIP

ON COMPARATORS its mostly A-D circuit but with one adjustable output ,to make it A-D use a few in series with a voltage divider like a bar graph chip (lm3914,or an6884 or others),with A-D it will have digital ouput ,I2C or TTL or PARALLEL there also a window comparator witch is 2 comparator with a high voltage leve and low voltage level and a window in between

Cheers Robotmaker

In the uk we have a saying " AS CHEAP AS CHIPS" it refers to potato chips , But i think it also refers to AN6884 chips to .:)

Thanks.

Hey Jstarne1, did you try out the pan/tilt set on the shoulders? Do they fit in the rubber boots? Also btw to you happen to have any extra from the second omni? Shoulder or neck?

@glickclick Have not tried the shoulders if they will fit yet , the neck is easy because its sooo wide. However now that you brought it up I'm doing that tonight as I should take the arms apart for paint prep anyways. If they fit it will be a close fit because I'm using ultra high torque 645mg and will probably upgrade to 995mg when I can because those are also standard size. Everything is coming together I'm excited for sure! I tested the hardware everything is good only piece left to test is the 250 watt m4 PSU. To make sure it can handle my hardware at full load.

I want to do a mouth on my project so I gotta find some bar LEDs , I prefer white or blue ones.
