Phoenix Online

From here you can do some of the experiments online.  The webserver calls the python program to perform the experiment and send the results to your browser. Experiments with a static setup only can be kept online.

Charging and Discharging of a Capacitor

The experimental setup is shown below (1 uF and 1 KOhm). Select the operation and click on the Submit button.
 
Username Charge Discharge
Fill the username field and mention it if you are reporting some error. ( Here is the CGI script running under Apache)
Getting the same curve everytime ?  Click Here for another version that will allow you to change the delay between measurements. If you want to change the capacitor also, send me a python controlled Robot to do that.

Diode V-I Characteristic Curve

(to do)

Your own Code

A very ugly and untested thing. May work for simple things like this:
p.set_frequency(1000)
print p.r2ftime(0,0)
print multi_r2rtime(0)

I have connected a cable from PWG to Digital Input 0.
