A "home accessible via USB" quantum random number generator is available. It uses two quantum bandgap effect (avalanche noise) sources, checks for correlation between them, whether the entropy generated passes randomness tests, and shuts down if there is a failure to be random enough. At the start of its life, it generates a little over 32 kilobits of entropy per second, which slowly degrades as the doping ions in the semiconductor migrate into the PN junction. It's also a little more portable, being about the size of a USB memory stick.
