Graphite powder as coil shielding

[baum7154]

In an effort to return this thread to its graphite shielding topic I have input information on the 2 stage amp modification in the CHANCE PI BUILD thread of the TECH FORUM. Questions and comments on the 2 stage amp are welcome there.

Thanks,

Dan

Hi Dave, Yes a 2 Stage could be added in most cases where faster sampling is needed. An appropriate design for the specific detector would need to be implemented. In my case it was added by interfacing through the single stage IC socket so no significant mother board changes were necessary.

Hi Dan
When or if you get some spare time have a ponder over the Barracuda and let me know in your opinion if anything along those lines could be done there for added improvement .

Dave

Dave are all Barracudas the same front end, motion vs non-motion? Can you point me to the latest schematic version or the specific one you are interested in?

Thanks,

Hi Dan
The one I am interested in is the original Barracuda (not the silverdog version) Its non motion , easy to find its hand drawn circuit together with hand written parts list it uses the tip127 in the front end.
If you have doubts will email you the necessary.
Thanks
Dave
