- I guess the simplest, but most expensive solution would be to use three
- cable converters and switch between them.
-
- The least expensive, and least convienient solution would be to get a
- remote which has channel up/down buttons and remote these to large
- buttons. It might, however, take her an excessive amount of time to
- step from say channel 4 to channel 36.
-
- Finding a cable box or TV with three "favorite" channel settings is
- probably unlikely, at least I've never seen one.
-
- So.... I'd probably build a circuit which, after you press one button,
- uses solid state switches to activate a hacked remote control
- transmitter. Off the top of my head, I think it would require an
- NE555 oscillator, a BCD counter (maybe a 7493), and an analog switch.
- Probably have to toss in some odd gates.
