Circuits and ideas for clocking/trigger/timing applications

wackelpeter

As big as my DIY home brew'n stripboard systems grows i think it's time to add some further logic and Timing functions to the whole.

Already havev a lot of dividers some logic and also some random modules

(3xYusynth divider, 1XCGS Master divider,2xCGS Pulse divider, 2xCGS Gate Sequencer,2xCGS Burst Generator, CGS Gated Comparator, CGS VC-Divider, Fonik VC Clock, some NAND, XOR, XNOR OR and AND plus a few simple binary counters i made from CD4060 and CD4024?? (can't remember right now)

...but i want to add some more dividers and possibilities of rhythm, clock and trigger Generation.

As sure as there are some more counters and simple logic modules included i also think about such stuff as Shift Registers, multiplexers, flip-flops and latches...

Currently have a CD4015 shift Register on breadboard which seems useful as a comeplex rhythm/Timing Generator when fed with different divisions of a clock signal at it's data and clock Inputs, generating interesting repetitive patterns.

Have had a look at the most suspect sub-Forum (The Lunetta-Forum) to hopefully find some ideas but there are so many circuits that could be of interested so i gave up for the first time. Unfortunately not many of them had Sound examples to catch my interest immediately or that i can get an idea of how it would sound/work.

Anybody here with some cool hints and advices for some circuits i should give a try on breadboard and of course schematics?

CMOS Euclidean Rhythm Generator is one that I like to use. The reset behaves a bit odd but for the rest it works great.
The 4089 is also a very nice chip.
Sierpinski/Hadamard Pattern Generators which you probably can patch up with what you already have.
and maybe a Morse Code Generator. Very Happy

Thanks Phobos, there seem to be some cool suggestions there.

The euclidian rhythm Generator already caught my interest but i wasn't sure, if i will ever try to breadboard this as there are more than 2 Chips involved.... Smile

mostly i simply heat the soldering iron and begin to solder when something catches my interest no matter how big the circuit is... Breadbording is a totally different thing to me, which i mostly tried to avoid...

But as said i have so many logic IC's in my bin, i must get rid of them and build something with them... and as Christmas is very near, i need some blinky lights too... so there's no excuse to not try any of those suggested modules Smile

Guess i should start the PSU for this small case today as i today got hold of a 16V AC wall wart with 500mA current Rating which seems to be enough for those things i have in mind...

For me, PHOBoS's circuit of choice is the NANDulator with large capacitors; 10uf and above.

I honestly haven't even tried it at very low speeds,. but the output is a 1-bit digital signal so yes it could be used here.

Also don't underestimate the patterns you can get with a Linear Feedback Shift Register which you already have the parts for. (nice for christmas too)

I would recommend adding some gate delays, very useful for triggering those semi-synchronized envelopes, amongs a range of posibilities.
The one I use are from Ian Fritz AD/AR (hey I notice his website is down... )

And if you like to generate gates and triggers from CV signals, Ians TGTSH is a very nice tool.

Now where are those schematics? It seems both his website and the Bridechamber are down. Crying or Very sad

Sorry, this really seems to be as we say in Dutch: "iemand blijmaken met een dooie mus"

cool phobos stuff!
dont know witch catches me more,

since today i almost ignored the digital stuff, but as i saw the Sierpinski triangle, wow!

i love those moments when u see an open door where the moment before was only a wall

so thanks

for the spiritual morning

cu,cheers,bb

ah yes, for 15V it's not so bad I was thinking 12V or less. It will still get pretty
warm though but just put a nice heatsink on it and it'll be ok. Smile

Nearly finished the first circuit for my small clocking, sequencing and logic box...

Unfortunately i ran out of pots, LED holders and sockets (just got 100 of them 3 weeks ago)

But it's working so far... It's a 8 step sequencer with CV out and individual gates for each step and also via switch pulses and a gate out for the selected steps and as i had no on(off/on Switches at hand the inverted Version of those... generated from a NOR with one Input to gnd and the other gate to clk and the other both Inputs fed via the Switches through the Signal from the individual gate out... This creatures components or subcircuitry are "stolen" from the MFOS 10 Step seqencer, Yusynth clock divíder and the CGS gate sequencer...

So far i've measured 35-38mA on the positive rail, on that Panel i've plan to build two simple versions of a 4017 Counter 10 steps each (bottom rows) and some logic...

Then i have a second Panel of the same size which will hopefully Feature some of the above suggested circuits...

I estimate that i will be okay with the small PSU i've build, especially regarding the CV Output of the sequencer... I left some space for some additional electrolytes and furthermore could switch to a stronger wall wart.
