36: Custom 84 Channel RC Servo Controller

Hi there this is one of three boards i will be using for the control of the various functions on J5 ie servos,motors,linear actuators,lights,relays,leds,solenoids,
sensors,etc this is being controled by
a small custom program i wrote in c.

how much did that controller cost? I am wanting do use some servos in a laser /LED light show and I need quite a few cause I am wanting to make it a moving head - so there about two for that - gobo control is 1 and then there is the Spirograph function of the laser which I want at least 3 ... also want to be able to add some blanking and diffraction grating so about a total of about 10 -

Hi :] i have a few questions

1]First of all didn't your servos get false "bursts" because of the closeness to other control servo wires

2] as i'm trying to control only 20(18+2) :D i have encountered a problem with generating pulses for such a mass of servos. I delay the min pulse at the start, and then increase it with 10us(the minimum difference which will make any change ) after increasing i check if any of the servo_pulses has been timed out, and if that occurs i switch the pin to '0'

and you bought all of those servos?

[quadrant2005]

that all depends on what servos your using and if they take there power from the three pin header, the larger servos seen take there own seperate supply, the header on those is only for the control circuit the h-bridge takes its power independantly
