  1. hi guys, I am working on a heart rate monitor and I am using the circuit attaced as my amplification circuit. I however have some conceptual question on how the circuit is working. The circuit diagram is located here : http://www.picotech.com/experiments/calcul...thysmograph.png . I did some research but could not find any satisfying answers. I am for example not sure what kind of op-amp configuration or why the op-amp is used like this. I also wonder why there is a 2.2uF capacitor connected to the potentiometer (It looks like a high-pass filter but i am not sure). It would be great if somebody would be able to explain those questions. Thanks alot!
  2. silence, music irritates me when i am trying to think.
  3. You could pipe the output from tcpdump into a c++ parser. Which i will be willing to code, if you could show a sample tcpdump output. For the graphing we could try to use the graphing library that comes with boost.
  4. He was supposed to send the SWAT team to mc donalds or something... I hope he will get his 18 years behind bars.
  5. The best thing i could do with 5000 bucks is to invest it in a small business. Lately i have been thinking of starting a small pizza slice place here in vancouver BC. A 500 square feet place by a mayor bus loop will only cost me about $1200 plus hydro and i can sell slices for 2 buck so i will need to sell 600 slices monthly to break even. This are going to be my expenses roughly: $1200-->rent $3000-->oven, furniture etc $400-->frozen pizza's for the first 2 weeks $400-->hydro, other expenses etc.
  6. You could also try something like this, rename a file like: file.exe.jpg If you are lucky the filter will only find the .jpg and then upload your exe.
