There’s room for another solution, especially if it could someday lead to a product sold for under $1500.

- ncmncm 5y agoA cellphone camera is, what, $5? Maybe you already have one. Or an audio input jack you can crank up the gain on. Maybe a radio transceiver, like for wifi or bluetooth? All our gadgets already have sources for way more truly random bits than we could ever find a use for. If you feel you really need to build something from scratch, resistor thermal noise is random. Likewise, diode shot noise. Total parts cost for either is well under $1. Combine them if you like; you are still well under $1.
