=85again!
Still waiting for the RS bits to arrive today =96 as soon as they do,
I=92l=
l breadboard the circuit and test and then start building into the rack
enc=
losure I have. A couple of questions though if anyone would care to
comment=
=85
1) cutting holes in metal =96 I need to cut a load of holes for 24 panel
mo=
unt BNC connectors and one mains power connector. Round holes are easy =96
=
rectangular not so. Any recommendations for a decent tool to cut a
rectangl=
e in the centre of a reasonably flimsy metal panel (I guess it=92s less
tha=
n 1mm thick)
2) Can anyone look over my circuit design for me =96 I=92ve taken an
existi=
ng circuit based on a single opamp but used an IC with two opamps on it
=96=
just need to check the interaction of the two circuits is ok.
3) Need to check how I should deal with the shielding from the video feed =
=96 does it go to AC ground i.e. grounded to the rack (which is hard to
avo=
id anyway as the BNC connectors do this) =96 do I need the shield the
inter=
nal cables running from the BNC connectors to the PCB?
That=92s it for now =96 TIA!
Paul.
