thank you, sorry for the lapse,

Would it be possible to build a circuit where the stamp only has to write a hexadecimal number to a pin and have that number correlate to gates on an IC is this a...

Also if I tied the ground lead of a battery pack to the ground on the board would this do anything to the board? Would it create a common ground?

Hello,
Need to know what is the maximum amp load/voltage load the Javelin can maintain. I have accidentally blown out a stamp in the past and do not wish to do so again. Also where is the Vm...

so I have been looking over everything, the load requires a very high current (4A) so i don't think the opamp would be a viable option, instead i am thinking of maybe a optocoupler and sending a PWM...

So I was wondering how best to make a DAC that is able to control an outside power source I need voltages above 5V and can't use the DAC voltage class is there a chip that will be able to discern...

So I am looking at using a thermisistor to monitor a wire's temperature that is submerged in either oil or antifreeze. I am wondering if I insulate the leads up to the sensor would that protect it...

what is the voltage/power requirement for a LM399, if i am correct in assuming that you connect it to a voltage and it either goes logic high or low when a voltage is above a set current correct?

What about a resistance thermometer? What I need is a sensor that can figure out if any point on a wire gets above 90C. I don't care where it is I just need to make sure it doesn't go higher than 90C.

So, when using thermocouples, is it possible to monitor an entire length of wire or does the thermocouple only monitor one point?

i turned it on patching from the header for the appmods, there was no echo

should I disconnect pin 21 as well or can i just make a bridge over from the vdd board socket? Thanks-Adam

No echo, no voltage across the Vdd and vss

Ok so my microcontroller stopped working, I am getting an IDE error 0056, I am connecting to the board using a USBto232 adapter and using a BOE Rev C. I was testing a transistor circuit by hooking...

Hey,
I am looking into using the javelin microcontroller to control 2 motors using a speed controller. What do I need to know to set up the microcontroller/run it. I know that I have to send a...

What if given certain initial conditions i just took the integral of the function used to find the acceleration two times to get position?

Hey,
I am interested in building a robot using the Mesmic Tri Axis accelerometer to figure out the orientation of the robot relative to a base point. Would an accelerometer be the best tool...

java i assume it is the same right?

Hey,
Had to take a break from the project because of college but now I am nearing the completion and I need to rewrite a lot of the protocols that transmit signals to the arm. Ok, so the...

Hey,
I have a couple questions,
1st- is the low/high byte transmission protocol really necessary, can i just send the integer to the stamp and have it pick it up in an int array?
2nd- How would I...

ok well my protocol sends int&0xFF first then int>>>8 so I assume that the highbyte is sent first so I will just put the int high before the int low then. Thanks!-Adam

public static void assembleMessage(){
int cmd = 0;
int bufindex= 1;
int messageindex = 1;
message[0] = 1;

while(bufindex <= 10){
cmd =...

low byte is int>>>8 right?

When I transmit from the computer to the stamp, here is the scheme I use to write to the output stream in the COMM API

outputStream.write(0x11);
...

hey,
I've been working on this code and I don't have the javelin in front of me right now but will soon, does this look good to interpret a control string if the first byte was 0x11 then...

well this was not intended to be narcisstic in anyway I would just like to get other people's take on robotics and reasons why they are interested in it.
