Oh that's understandable, I still have the 6 and 7 ordinary channels I can always use.

Those multiview boxes are great! I have one for my old sets.

Bear in mind the output of the T35 is extremely 'HOT' and will require some attenuation of the signal so it does not overload the TV tuner.
I think right now I am drawn more to a Multiview as it's so simple and being a beginner in this, I need simple to be able to learn more about the whole set up. I think the digital switch over hasn't helped as it means more technology to get to grips with. (Shouldn't be too hard most of the time, hopefully)

Sorry if this is a really simple question, but HOT doesn't mean temperature, does it? I've seen it before on websites, and on the back of a PCB on the neck of my CRT.

I should say this would be quite a complex project for someone who has never used / programmed an Arduino before. Although the aforementioned I/R library does 90% of the complicated stuff, you'd still have to be comfortably familiar with the Arduino programming environment in general.

I would possibly consider this route, but maybe not as a first option as I've never programmed before (Apart from a game of Pong) so I have no experience in programming.


I think it would be best for me to move the idea aside a little, as I would have no clue what I'm doing.

Then, the basic requirement for the project is to take in the ultrasonic channel change command and convert that to an IR command which selects the required channel on the Tivo or other set top box. The modulator does not need to be controlled at all.

The Ultrasonic remote will still change the channels on the TV as well, but no matter what channel you change to, it will still see the output from the modulator.

I think this may be more of a possibility for me than the Arduino idea, as it does seem to be much simpler, and I think I'd understand it a bit more. Thanks for that suggestion, I'll keep that idea in account.


Thank you all for your replies! I really appreciate it.
