Is there a way to dim the LED on a SunRay 1? I have one installed
in a bedroom and it's a little bright. Covering the LED works, but
isn't very pretty, and I don't really want to open the case to add
a resistor.

_If_ the LED is controlled by the SunRay firmware, then in principle
it could be altered to "dim" the LED by just making it flicker very
fast. That's the only way I can imagine to do it without hardware
mods, and it would arguably be more difficult and higher risk than
altering the hardware. Also, it would have some performance impact,
or else the LED would be allowed to go to full brightness when the
SunRay was busy.

If you could find some very thin and flexible dark translucent plastic
sheet, you might be able to fabricate an almost invisible cover. I don't
know what the LED looks like, but if it's round and sticks out a bit, you
might be able to poke a dimple into such plastic with a blunt object, and
then cut out the dimple with a very sharp pair of scissors. If it's flat,
then it should be easier to cut out a piece to dim it.

Thanks for your comments.

It almost certainly is controlled by the firmware, since it changes
color during the startup process. Actually, turning it off completely
would satisfy my needs, and that shouldn't consume much in the way of
resources. Does anybody know how to just turn it off?

It's an odd shape; I'm not sure I could do a good job of that --
hopefully there's a better way.

Several layers of scotch tape or a single post-it note placed over
the led should dim it. I have a Sony PDA with a similar annoyance
factor.
