The spooky2 boost module will increase output by combining channels. This can be increased even further for single channel devices by using the spooky2 boost cable in conjunction with the module.
That said I believe I read this configuration(boost & cable) was capable of delivery 40v peak to peak. Though don't quote me on that atm. I'll have to check when I get home later today.
On the matter of the remote I never thought of using a blood sample. Though I wondered if you placed the sample directly on the plate or did you use some form of applicator?
Thanks for the information btw.
I will definitely try doing this, this evening also. - mind over matter or not :)
