Re: IR receivers - plasma filters?

["rb_ziggy" <rb.lists@xxxxxxxxxxxx>]

This may sound a bit bizarre but I picked this up and it worked for
me.

Cover the IR receiver with a bit of tape (I used the brown packing
tape used for packing parcels) - this in itself did not stop IR or the
interference.  Then colour over the tape with a black permanent marker
pen.

I found that this did enough to cut out the interference (shown by the
flickering receive LED) without attenuating the signal from my Pronto
control in any material way that affects usability.

Definitely worth a try as its dirt cheap so nothing to loose!

I wouldn't be surprised if the "optical filtering" is something
similar!

Trouble is, the plasma and one of the bedroom LCD TV's create havoc
with the IR, pumping out so much interference that the IR network is
unusable :(
