~ Small Ramsey chamber mod for James
Dougherty ~
Drilled holes and filed out rear plate to fit
(2) USB and (2) HDMI
feedthroughs. Notice the countersinks on the USB
holes, these
are to make sure the plate is completely flat
for a good anti-RFI seal of the USB
feedthroughs:
Here are the USB
and HDMI feedthroughs.
Sieren conductive fabric was cut to form gaskets for the HDMI
feedthroughs
since they are not shielded, these gaskets will
be located on the plate inside the Ramsey chamber between the plate and
the HDMI
feedthrough - the idea being to have continuity between the plate and the
metal outside part of the HDMI
connector:
This pic shows the Sieren conductive fabric gaskets
in place on the HDMI
feedthroughs:
Here is the completed modification:
