that 9v pin is a Vin on my board this is the power bit of it  (Reset, 3v3, +5V Gnd, Gnd, Vin)

Huh???? My board has the same layout (without checking) as the board shown in that image I posted. Do you have a NG or Diecemila, they might differ...

Mine is this one: http://mcukits.com/?p=9 Diecemila compatable..

The 9V pin is the 2nd (from left to right) orange colored pin at the bottom of the image below.

so the usb isnt enough to drive it? also im getting the rx and tx lights on low wen its on battery power, they just sit there slightly on (in all sketches) but they remain off on USB power (unles being used)

It seems that they do not like runing i\under usb power and only cooperate on battery :S
are your servos powered from the +9v pin or +5v pin on your arduino? the 9v pin only carries power when you're using an external power-source (not USB).



The 5V pin naturally ( i don't see a 9V pin, what one is that?) smiley

ok scrap that it seems to be working ok now  :-? (the code above at least.. will test more)

Im having trouble with most of the servo codes i have. they dont seem to be doing what they are sposed to..

my mini servos do not respond to any of them, and my futaba S3003 taken to their extent and the program just keeps trying to push them beyond that instead of making it go back and forth like the program says..

the code in question:
Code:
/*
 * Servo Move Simple
 * -----------------
 * Move an R/C servo back and forth (0 to 180 degrees) using
 * delayMicroseconds() for pulse and delay() for time between pulses.
 *
 * Created 18 October 2006
 * copyleft 2006 Tod E. Kurt <tod@todbot.com>
 * http://todbot.com/
 *
 * Adapted from Daniel @
 * http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1160470155/0
 * Rotates servo through 180 degrees, using "servoPulse" function  
 * adapted from "Temporary Servo Function"  by Tom Igoe and Jeff Gray
 */
 
 
int servoPin = 7;            // R/C  Servo connected to digital pin
int myAngle;                 // angle of the servo (roughly in degrees) 0-180
int pulseWidth;              // function variable
 
void servoPulse(int servoPin, int myAngle) {
  pulseWidth = (myAngle * 9) + 700;  // converts angle to microseconds
  digitalWrite(servoPin, HIGH);       // set servo high
  delayMicroseconds(pulseWidth);      // wait a very small amount
  digitalWrite(servoPin, LOW);        // set servo low
  Serial.print("pulseWidth: "); Serial.println(pulseWidth);
  delay(20);                          // refresh cycle of typical servos (20 ms)
}

void setup() {
  pinMode(servoPin, OUTPUT);          // set servoPin pin as output
  Serial.begin(19200);
}

void loop() {
  // cycle through every angle (rotate the servo 180 slowly)
  for (myAngle=0; myAngle<=180; myAngle++) {  
    servoPulse(servoPin, myAngle);
  }
  delay(1000);
}

as soon as it is uploaded to the Arduino it moves the servo to max position (clockwise 100%) and tries to push it further. it doesn't move in the other direction at all. why is it doing this?

My mini servos do not seem to do anything when they are connected. they are E_Sky micro servos 8g

Both servo types work perfectly in the radio kit i have (Futaba R114F Rx, and Futaba Skysport ss3 Tx) without problems.

once i read thru the sparkfun info about exporting the gerber files and used one of their suggested gerber viewers to check them it was ok smiley
i chose the files needed, zipped them up and sent them to the batchpcb bot for analysis, it seemed happy with them.
apparently they have a special cam file that will generate the files from the layers properly. smiley

i'll look into that one smiley thnx smiley

keep em coming smiley-lol people need choice smiley-razz

i dont need 10 boards tho. especially if there turns out to be a problem in the layout or design that i wont discover until i build one.

i'll only want that many wen i either need beta testing or sell kits.
357  Forum 2005-2010 (read only) / Bar Sport / Re: dirt cheap PCB manufacture on: August 07, 2009, 11:41:48 am
thnx thats one, but its too many boards and too much money for wat im after smiley-wink

thnx for adding to the list tho smiley

-_-

thats fine for single sided (i only have single sided copper clad) simple boards..

but no good for double production prototypes with impossible to draw by hand tracks. (yea i have no access to a laser printer so transfer methods are a no-go).

i'm talking about proper made boards.

I need to know a place where i can get some prototype boards knocked off at a really cheap price, im using eagle free version.
it wouldnt be fun spending money on getting a batch of boards made up and finding out something is horribly wrong on them, thus wasting a load of money most of us do not have. and also dont want to pay through the nose for a few boards to test a design.

and i am sure there are others that would like this info too smiley-wink

so why not list them here smiley
