Re: Can channel buttons be put to proper use?

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. Quote:
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. Quote:
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. |

Oh okay, I won't be too close to the TV when it's in use anyway.
Thanks |

Re: Can channel buttons be put to proper use?
How's this for a "steampunk" option:
When the TV has selected a particular channel, a LED or similar lights to tell you which channel button it is tuned to. Bring out the 8 LED drive wires and use them as logic inputs to a buffer stage for each - maybe a single FET for each or maybe all integrated into a buffer type IC. Take the outputs from each buffer and send them to a momentary solenoid that pushes on the corresponding button on a FreeView remote. The FreeView output would need to be modulated onto a UHF channel and all the TV's "channels" would be tuned to the same UHF frequency. If you'd be prepared to take the FreeView remote to bits, a relay or 4066 (for example) could be used. No computer programming! Graham

Re: Can channel buttons be put to proper use?
That's a bit risky on a pre-SCART set which may well have a live chassis, though .....
You could maybe use opto-isolators, by wiring their LED inputs in series with the channel LEDs .....
