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)
