  1. Yah actuallt I'm thinking of screwing this whole thing on the remote and just use a microcontroller. I also need to know if anyone knows of a site where it has a schematic for a radio where you can pre-tune it to 1mghz AM somehow?
  2. Oha nd also in the reciever is anyone positive that is I have a radio plugged into it if the rectifier will work, because I happen to have found a small transformer that I bought and never used.
  3. Ok, it'd be cool if you post some links. Then do you know of any other way to get one pulse, two pulses, three pulses ect... out of a circuit when you push a button?
  4. Well its not really the 741 I am having problems with. I know how to use it I just can't figure out how to make it so it will work with the sound input. I also am trying to make a comparator so thats why I don't have a feedback line.
  5. Well YT, what do you mean by clipping it and filtering it? I don't know if I did it right but on sme other boards they said it would work. I looked at those tutorials Kedas and really didn't find out anything I already knew.
  6. Ok well this is what I have for the transmitter and the reciever. If anyone was wondering the reciever is plugging in to my parallel port so the output of the reciever is supposed to be one spike, 2 spikes 3 spikes, etc.. all the way up to six as on my remote. My remote My reciever
  7. Yah I am trying to make a volume switching device. I have looked at many diagrams and read up on how it is used but just I couldn't really find anything close to what I am trying to make. Maybe give me a tutorial on what I need to know?
  8. I was thinking the op amp would turn on the output at a high sound. Would like 2.4 volts be good for this? So what your saying I need to take the grounded out completaly?
  9. http://img.photobucket.com/albums/v358/lookatmytool/schematic3.png I think I fixed it, I moved the ground to the other side, Should it even be there at all? If you can tell me how to get the values of the resistors somehow. Also I am making a remote transmitter please tell me if this would work... http://img.photobucket.com/albums/v358/lookatmytool/remote.png Each button is numbered at the top when that button is pushed the output of the second 555 is supposed to 'beep' that many times.
  10. Well I have a circuit that takes sound input. It runs it through a 741 op amp and then turns on bit on or off if there was a high sound. I don't have the values of the resistors and whatnot figured out and hoped you guys could check my work and maybe route me to some pages on how to calculate the values. Or hey if your really bored you can do it for me! Edit forgot the link hehe... http://img.photobucket.com/albums/v358/lookatmytool/Schematic2.png
