Curious; anyone know much about what these inexpensive (comparatively,
price seems steadily falling) ASIC Block Erupter USB Bitcoin miners
can be adapted to doing? Could they be repurposed as RNG sources?

I know they are designed / programmed for running the SHA256 hashing
employed in mining Bitcoin, but as the difficulty rate goes up, their
value in that arena becomes less and less...

Just wondering if they might find new life as inexpensive RNGs. Any
pointers to the circuit or the code they run?

Disclaimer: I have no idea if this is even remotely a valid or good
idea... But a cheap hardware thumb drive RNG might be useful, no?
