Mechanics of FLUXBABBITT.

Cardano Prototype Tidbits: TRNG Boards.

Cardano is a joint project of yours truly and Mircea Popescu. The objective: an inexpensive, user-auditable gadget which attempts to deal with the problem discussed in “Don’t Blame the Mice.” Refer to Mr. Popescu’s page for more details.

Don’t Blame the Mice.
