Best Aleatory 3 Decimal Digits

This circuit use four oscillators. Three first of them attack three ADC. Fourth is CLK to latch the data. CLK has been getting from a 555 in the "Voltage Controlled oscillator" mode (FM). This CLK change time between pulses and ensure differents times to latch the data. More impredecible RANDOM data. All frequencies are different to ensure minimum time before they coincide again with not integer number. Orange wave is used to controlling the 555. Green wave is CLK to fetch data. I think this is the best "aleatory number generator" I have made. It can be modified to show 1 to 49 (lottery)... I hope you like it.

I think a long enough CRC code is much better as pseudo random generator

Build it 😀

even 64bit versions are possible, here a 11bit CRC code with 1bit output as pseudo random, analyse the bit sequence and compare its randomness with your circuit http://everycircuit.com/circuit/5341926363234304

I can't see it from my Android

My concept is very different. Multiple digits can be added. Multiple waves can be added.

A Voltage Controlled oscillator ensure differents points to latch.

Yes, yours is very different. I think a CRC shift register is much better. Clock four cycles and take four bit values from the shift register which are very good pseudo random values. Only make the register long enough to not repeate its sequence to early. 11 bit do generate 2047 bits random before it repeats its sequence. This needs a few minutes within EC. 32bit repeats after 4.294.967.295 random bits and would take almost forever within EC

BTW, you can't read links or you can? You say you can't but then you say your concept is different. Very strange

I just saw your circuit. It is not too bad, it brings me some ideas for the future... So, you said 11 bits, my is 12 (now limited to 1000 because it is in decimal). My pulse train attack a 555 which gives us a FM modulation. I think your circuit is good but is not so different from mine. The best noise generator will be designed soon. I don't know who...

Os yes?...

Sounds all very strange what you are saying. Maybe before you start built the best and most effective and versatile and rapid and economic and whatever ... Think about how to prove its a good or its a random generator at all. Do you have an idea how to make an analyse circuit for random generators?

It was a joke 😉. I was speaking about you and me. I have a little bit of how... But EC is not available for that. For now your circuit and mine 'cos I don't have seen any more...

Speaking about analyse circuit for random... Yes. A buffer fetch one data (example: 263), then is compared with random sequence, step by step, when find coincidence all stop and a pulse counter show us how many number has passed.

I don't know if there will be enough space...

Maybe digit to digit.
