Hi,
Just wanted to thank you for providing information on a simple GSR reader project. I’m a research student at Newcastle Uni and have just developed your code and reader for part of my work.
The code I developed uses the data received from the GSR reader to prduce an aura effect around the user, I shall be posting the annotated processing code very soon on my blog, http://dm.ncl.ac.uk/davysmith/blog

Keep up the good work

Davy Smith

Any chance it’s a difference between dicimelia and duemilanove (running a 328 chip) perhaps? I’ve tried to copy this gsr: http://www.funnydata.com/gsr/index.php?title=Hardware2 to try and boost the microvoltages and I get a similar issue. Any chance to you can point me in the direction of more precise/ better ways of doing this?

Nathaniel, I’m not sure what the problem might be. If the circuit is set up right, then i would try attaching the pennies to other parts of the body.

Che-Wei, Ok I have adjusted the delay in either direction and no luck there. I cleaned my pennies thinking that I may have a conductivity issue and I do get a fractionally better reading if I spit on my fingers and then touch the pennies, but the only time I get a sizeable reading is if the pennies touch. Then i get a large spike. Could the wiring have anything to do with it? It seems so simple that I am doubtful. I have tried different resistance as well as a pot too. Not a lot of luck besides making the lines follow the swiping of the pot. Dont know if you have access to the info you pointed putai towards but once figured out I’d like to make this more precise.

thanks again

Nathaniel, I would play around with the sample rate of the code in processing. Change the delay(50) in the draw loop to other values. You can also try out different values of resistors. Good luck!
