Random Gates Circuit using 4093 & 4013

[gasboss775]

2 fast oscillators of different frequencies are combined by in one case an OR gate and in another an XOR gate. Snapshots of this complex waveform are captured by the 4013 D type flip flop at a rate determined by the tempo clock. This could also be from an external clock.

I will add the other 1/2 of the 4013 later, the one shown deals with the output of the XOR gate, the other will deal with the output of the OR gate.

I am intrigued by your XOR gate, haven't tried to figure it out yet though. Are those actually zenerdiodes
and if so do they have the same voltage ? Sampling high frequency oscillators does indeed work well for
'random' especially when you throw a couple in the mix. A shift register with a high frequency oscilator
connected to the data input also works nice and you can attach a resistor network to it to create a semi-
analog signal.

The XOR was explained here : http://electro-music.com/forum/topic-68544.html - interesting thing :-)

oh shottky diodes, that makes sense, I mixed up my diode symbols Yeah, regular diodes should do fine
but it's always good to keep the voltage drop to a minimum.

I am somewhat surprised it doesn't work with a CD4094 it even has an extra latch, I guess I should do some experiments
with it. It seems to work fine with a 4015, I like connecting one of those flickering teacandle LEDs to the data input.

I get those LEDs out of electronic teacandles, I think the last time I bought some they came in a pack of 4 for €1,-
You can also get the LEDs separately on ebay in a variety of colors.
