"Midi / pulse clock divider, with swing, running on arduino"

cool

Nice DIY.

Thank you!

Here is a post in the DIY forum with some details about the schematic/code.

well this pretty much rules. SlayerBadger!

just out of curiosity what is the depth of the build?

want to share your code at all?

i've been wanting to make an arduino module and i have 2 unused minis around. i'm not the best at electronics and my concern is the details - did you use protection on your jacks? what kind of signal can it accept/put out? i'm assuming you can use the doepfer-style connector to the 5v?

sorry for all the questions...

yes, I'm more interested in how the i/o is handled smile

I don't need midi at all.

outputs are straight off the digital outs.. High and low.. real simple.

the digital outs are great for clocking, logic, and gates.

for a simple clock and divider w/0 midi.. i would use an interrupt based program. this way you can reset and even do tap tempo.

i wanna try to make an arduino module with some jacks, knob, and one switch that designates what 'program/module" to run.

This is very cool!

A ong while I have been wondering why why there has not been a din sync modules produced!

Well done!

hey synthomaniac... ever considered doing some uk module building workshops? I can build kits fine, but anything more is a bit daunting.

well so much for that module. lol.
I had one in the works almost just like this one. more division outputs though + a few other features..

lol.

Looks great!

would totally be up for a workshop guys hyper

I have quite a bit of diy soldering experience and even a scope I could bring (although I'm not sure its calibrated) however i lack some of the technical knowledge useful in debugging and more complex builds

always good to build stuff together and share skills

@Monobass, Tombola and snufkin

Workshops sounds like a great idea - I thought it might be neat to combine a workshop with a Modular Meet and have made an enquiry about doing that at the next London meet but that event is not looking too hopeful.

I have had some requests, in my DIY Prototyping Kit topic on Muffs, to take a design from concept through to build. One way is as an online project, a bit like an electronics mag project, but the other way is as a workshop.

I'd like to gauge the interest, location and content/format. So here are some questions:

How may people want to do this? Where are you located? What exactly do you want to get out of a workshop?

The options for the content/format are:-

Basic electronic theory - Ohm's law through to op-amps (simple arithmetic no heavy theory) - so you can work out the resistor values you need for an op-amp mixer for example or working out what value resistor you need for a LED running off 12V - that kind of thing. Signal parameters such as voltage, current, load and output impedance, frequency.

Basic synth building blocks - VCO, VCF, VCA, ADSR, LFO circuits - basic theory of voltage control, gates/triggers etc.

Basic skills - soldering, laying out a perf board, measurements with a scope and DMM.

A guided project - e.g. design a LFO, understand how it works, lay it out on a perf board, solder it together and test it. This could be done in a hardware agnostic way using a bunch of pots, components and perf board or could be done using a Synovatron prototyping kit with front panel for a more complete solution.

Please ping me your thoughts and contact any buddies who may be interested too. This will take some organising and commitment from everyone and I'm more than happy to present this if there is enough interest and we can accomodate everyone's needs.

Check out my blog for the CV Tools Project which is a bit ambitious for a one day workshop but gives you an idea of the design/development process (we could just do a build CV Tools Kit workshop if you fancy building one but need a bit of help).
