nvm its not accurate enough i have another way to do this. thanks for no one responding anyway

I simply want to make 2 circuits one to transmit a radio signal on whatever frequency, another that will output it's strength. It can be analog, I know how to read it with a pic microcontroller (they have analog to digital converters). I want to be able to distinguish very precise distances but they don't have to be any farther than the average room. Thanks, I'm trying to be able to locate a position within a room by using 3 sensors for the 3 dimensions, if i can do this, and output the position threw serial to a computer, add a video headset, 3 gyroscopes to distinguish the 3 other dimensions of position (head tilt side ways, forward/backward, and left right). I can then write a program in open gl to put me in a virtual room. I've read about some positioning devices that use infrared leds but i dont' see why this wouldn't work

word pad

well i came up with this idea and i think its the one im going to be using, i don't need any more help, thanks anyway: http://www.h4x.co.uk/up/robotics.jpg

lol

Hey, I'm in this robotics class and i've built a robic arm that I am to program in c++ so that it can sort different colored marbles. Were supposed to create some sort of loading device to that will allow the arm to pick the marbles up one by one. And at the same time, using phototransistors + leds to determine its color. Though I know how to use sensors to determine its color. One white led on one side, 3 phototransistors on the other (ryb, and all the marbles will be clear). I wanted to know what sort of ideas you guys had for the loading device or "hopper". Currently I had to come up with a new idea because my old design using a tube would not allow me to change the size of the marble. I'm thinking a ramp with some sort of V shape down the middle of it. With a size good enough so that small marbles can roll down it while large ones can also. I drew up a picture in sketchup but its my first time so its not all filled in, see if you can make out what it really is. Anybody got any other ideas for this?

not nice, i learned javascript in 7th grade. Yes out of an 800 page book. I just cant remember all of it. I tried to just modify a variable in the parent but it didn't work

actualy no, your not doing my homework lol. I'm making a flash thing for a woman thats paying me for it and i told her it would be done tomarrow so plz help quick

Ok, If i have a parent window running my source code, and a sibling window launched by that window running my code, how can i get the parent window to check if the sibling window is open. I need an answer real fast i have to have it by tomarrow, thanks.

I have no idea how i can do this, are you sure you cant just find the script?

one of the scripts there said there was no way around it, are you sure you know there is?

hows it coming? have you given up? there is still time but i still have a deadline your my only hope, lol.

i've tried that, the problem is internet explorer prompts the user to close the window.

then the pop ups won't work properly because the flash file tells internet explorer to load an url that is actually javascript code to load the pop up. So i would get 2 windows, one with for some reason has the text "[object]" in it.

I say do visual basic then c++. Only because I didn't and it took me a long time to learn javascript (which i have know idea why i learned first, and no its not java) with no programming experience at all. You need to understand how programming languages work before you take c++ so it makes most sense to get the concepts down before you can take on c++. And after you take vb you might just not want to go onto c++. I never learned basic, i went straight to javascript (more difficult, similar to c++ and java) in 7th grade, read the book over the summer. The next year in 8th grade i spent a trimester learning c++ (45 minute periodicly threwout the school week). Now I've learned lots of languages easily which you might find once you've learned c++. Now i've come accross java. This is kind of like c++ except for one thing, it can be used in alot more places alot easier. So this is also a possibilities since industries are moving to it and it fits very nicely into web pages as applets. With c++ you cannot do this and you would have to spend alot more time reprogramming. Lastly, java and c++ dont do the graphics themselves. C++ may use tools such as open gl or direct x and java (from my impression so far) will use other libraries to do this. Does that answer any questions? w/e i had fun typing ne way
