I'd like to conjure up a random bit generator.

Just feed it a clock and have it generate random bits.

74HC... components preferred... I have most everything in that family
in my parts bin ;-)

Thanks!

I posted some pages of Applied Cryptography he

http://www.filedropper.com/lfsr

The pages contain the information you need to build dozens of different
LFSR's of maximum period using a couple of 74... series. IIRC you can
replace the XOR function with NXOR and get a maximal period LSFR that
will self start (the all zero startup state becomes a valid state for
the LSFR)

Link times out :-(
