Precisely my point. Or, rather, they do meet my needs, but my needs do not include having this stuff contribute to the entropy estimate. I can't trust that it is truly entropy. That doesn't mean it won't help keep your random numbers look random, of course: it still mixes into the pool.

Use an FM or TV tuner and use the white noise for entropy. I'd trust that.

Really? That noise is often fearfully non-random and highly correlated, and anyone with a radio transmitter or indeed any electrical device can introduce new patterning. It's... not a good noise source on its own (though obviously it contains noise, so it could probably contribute *some* entropy.)
