Simple circuits using the (ancient) 2N3904 transistor abound on the

Here's a newer circuit design specifically for battery-powered
cryptographic use and with lots of analysis and comparison with
another circuit:

None of it requires cutting-edge technology. The main issue in the
past has simply been that it wasn't part of the original PC
architecture, so things like "looking at mouse movements" needed to
be done at first until it was added to modern hardware.

Exactly! All the stuff about lava lamps, helium motion inside hard
disks, etc is just gimmicks. Real random numbers are tiny electronic
components built into CPUs, HSMs, etc.
