I have seen a couple of articles on
modifying an AM/FM radio to receive
SW, but can’t seem to get it to work. I
have tried on all three of my analog
tuned AM/FM radios, but to no avail.
Can someone supply a working
modification? The three radios I have
access to are a GPX Personal Receiver
#A2094AQUA, GPX Clock Radio
#D503CLR, and a BBS Cleartunes
I have no direct access to the
Internet, so I cannot do searches for the
information. I can have some articles
printed if I can get URLs. I also cannot
simply buy an SW receiver.

My mother has Alzheimer’s and is
unable to operate her television
anymore. We had a very simple remote
with about six large buttons which she
could use. That TV broke and our new
37 inch LCD is a good size for her,
but the remote has about 40 tiny
buttons which she can’t see or
remember which ones to press. She
occasionally had trouble with just six
buttons because they were similar in
shape and location.
The functions she needs are TV
off/on, volume and channel up/down. I
want to build a simple remote with
giant buttons that are perceptually different for each of these two-dimensional
control functions in hopes that she will
intuitively feel the difference.
The volume controls are most
crucial and frequently used. For most
programs, she needs to turn the
dialog parts up, but then the action
background is too loud for her and
must be turned down. She used to be
able to use her own remote on the
old set, so I would like to fashion a
programmable remote for her.
In the past several years, it has
become harder and takes greater
pressure to make contact with most of
the rubberized keys on our TV remote.
Inside, I've noticed a slimy film
covering the circuit board and keys. I've
cleaned everything with contact
cleaner. It worked for several months,
then, the same old problem re-appeared.
Does anyone have the same problem
and what did you do to solve it?

Is there a unit or circuit to convert
HDMI to IEEE?
Years ago, I built several "Nothing
Boxes" that fascinated friends. They
were boxes with six to 10 flashing ne2
lamps. They were fun to watch and
