4060 mini sequencer generator

JLS · Posted: Mon Dec 16, 2013 1:03 pm Post subject: 4060 mini sequencer generator

Hi all

This is my first mini (or micro ?) luneta experiment Smile

Base is 74HC4060 cmos ripple binary counter and some discrete parts.

Sound examples very soon.

some nice recordings, can you provide a circuit please?

PHOBoS · Posted: Wed Dec 18, 2013 1:22 pm Post subject:

nice sounds for a one chip circuit, did you hide some parts on the other side of the board ?
I'd like to see some circuit pr0n aswell Wink

Hi

Only one side only one IC and few discrete parts Smile

Today some new examples and pictures. Scheme soon.

Why old germanium diode ? Added some nice noise.

Great stuff. That last one, sequence with external 100uF capacitor and germanium diode and one external led diode, has a lot of low frequencies. It nearly shakes my house down. Laughing

DUBmatze · Posted: Fri Dec 20, 2013 2:01 am Post subject:

.... phew, good morning.
i sitting 3 coffees and a half mixtape in front of my laptop now.
Shocked

the 1uF, the 2 10nF, the pots, the 220r and the diode a some kind of dutycycle osc (that is running on verry high freq). the unstable out is some kind of a rampsquremixout. iam right here?

but what u can read from the LEDs? They just looking fine wile blinking or they for affecting the LDR?

JLS · Posted: Fri Dec 20, 2013 5:44 am Post subject:

LED diodes not only for blinking - make characteristic sound patterns Smile

PHOBoS · Posted: Fri Dec 20, 2013 6:47 am Post subject:

aha, you're putting extra components in the connector,. i didn't expect that. Very Happy

I've redrawn the schematic to see if I could make sense of it,. but I don't really know what's going on.
well done, well-done

I do wonder if it's correct, with the reset pin only tied with a cap to gnd,. I'd almost expect it to be connected between the 1K resistor and the LDR.
And what's the reason for powering it with 3.3V (instead of 5V) are you using a computer PSU ?

Hi PHOBoS

Many thanks for better scheme Smile

I checked it and well done.

Yes capacitor 1nF between rst and gnd is true.

3,3V is for my other connection between 3,3V PSoC ,Parallax and FPGA micorcontrollers.

Germanium diode and cmos 74HC IC is ideal for some unstabilities and characteristic sound/noises. (unstabilities fractals and chaos very interesting me)

My new experiment

Arduino Uno + Ronin synth shield + my 4060GEN.

Simple sketch for Ronin - FM synth with external gate trigger and frequency modulation.

Example 001 with external 100 uF capacitor for slow sequence.

Examples 002 and 003 is fast without external capacitor.
