+mizapf Posted October 19, 2020 Share Posted October 19, 2020 I always believed that you just need a source of Brownian motion, preferably a cup of hot tea. 1 Quote Link to comment Share on other sites More sharing options...

Probably true but not nearly as fun as 100 Lava lamps, a pendulum and a Geiger counter. Quote Link to comment Share on other sites More sharing options...
wierd_w Posted October 20, 2020 Share Posted October 20, 2020 Aren't reverse-biased zener diodes cheaper, and faster? https://hackaday.com/2020/05/23/a-4-bit-random-number-generator/ The circuit could be scaled up to any size bit-depth. 1 Quote Link to comment Share on other sites More sharing options...

GDMike Posted October 20, 2020 Share Posted October 20, 2020 (edited) Hmm. Not just Russians, but add social media selling your info. Now, i need this so they don't know who I am. Oops I need a lava lamp to get started. Couldn't I just look at my analog clock on the wall and get my random number. Bwhahaha Edited October 20, 2020 by GDMike Quote Link to comment Share on other sites More sharing options...

It's real hard to get the cats to leave the monitoring equipment alone. Also, despite being notoriously difficult to corral, their migratory paths follow predictable patterns, (at least when the monitoring equipment is not ditched within seconds of installation.) Cats really are not a good source of random--It's a common mistake to think "does not comply with ordered environments" == "Chaotic". Rather, the cats simply have no desire to comply with an externally applied source of order-- they are rather orderly within their own behavioral domain, and simply refuse any externally imposed ruleset.
