This is the same circuit of the video "Random Generator" but without leds. To the place of the led there are eight display led TIL311. Therefore this circuit generates one random sequence of exadecimal characters.

Are you current limiting the seven segment LEDs? I can't make out any resistors under the mass of wires. Just wondering.

TIL311, read the datasheet

display the kanji set, and you've got yourself a matrix!

[Alu10000]

Good idea :D

[mainedoggie]

What type of LED display are you using? Are those TIL311 ?

[Alu10000]

Yes

I know of a known hacker who got busted, worked at a casino and got ahold of the code for the Kino machine, which was not a random number genorator program, but used a formula. Someone also found a cheat in the old game show Press Your Luck. The computer in that game show did not use true random genoration. With the threat of hackers and cons from the inside, likely casinos have went to pure random machines, but the machines are only as secure as programmed to be.

Indeed you can generate random number. For example with closed loop of even "not" gate, without external clock. It oscillate with an not so accurate frequeny. The drift is quite random and often is used to produce "true" random number inside cpu.

Oh cool. Didn't realize the TIL311 had it's own logic. Neat project, good job.

its trying to warn us of something!
