Hi Devidas
My suggested changes would be....If you're going to use batteries you'll need 3 
of those 9 volt batteries, connected in series to give 27 volts.  Can't say how 
long it will take, but with one battery it could take a fair while.  Remove 
electrodes at regular timed intervals to clean them before resubmerging them, 
say each and every 30 minutes?
Other than that, you could get a small plastic electronic hobby box and solder 
everything together in that, banana plugs to insert the electrodes, and a 
transformer to convert AC mains power to 24vDC output.
If you google you can find how to make your own magnetic stirrer, if not, I can 
tell you how I make mine.
May I ask why purchasing a ready made machine is out of the question?

Subject: CS>First attempt at making EIS




Hello all,
Now I am all set to make my own EIS, using my own generator.I am staying in 
Pune, India and purchasing readymade machine is out of question.
I took a pyrex 500 ml glass beaker.
Pure silver wire 999, diameter 2.5 mm length 300 mm two lengths.
Bent them into a big U each with U half diameter 50 mm,
Took a plastic jar lid, drilled four small holes and 
fitted the silver Us into them, separating the Us about 50mm
Took a 9 volt battery and a 10k ohm 1/4 watt resister and wired the circuit.
Filled the beaker almost full and now to start the brewing. 
My question is, how long should I run the brew ?
I yet don't have stirring, which I will have to do manually using a plastic 
spoon.
Have I done all this correctly ? Or anything needs to change ?
Please reply,
Regards,
Devidas
