Thank you!

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

hey mate - PM me about the filter (not sure what's up with my messages, but some don't seem to have been sent, and yours came up blank)

low pin count... arduino... You can probably run this on a tiny breadboard and this:

hi tombola - you messaged me about a doepfer filter but for some reason your latest message came through blank, and ones i've sent you just go to my outbox, but don't appear to have been sent

you can get me on pencilpreston@hotmail.com if you want

cheers

It's not especially deep - about two inches?

You don't need to use an actual arduino board, or even the Mini that Wetterberg linked to, just the 28 pin Atmel chip with a (very) few supporting components

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.

If you PM me I'll send the code - it's pretty scrappy, not in a state I'd want to 'publish'

Didn't use any protection. The outs are straight from the digital pins. The point is it's literally an Atmel 328 with a few supporting analog components = cheap in everything but your time.

I've fired probably +/- 6v into the inputs with no trouble. You *should* protect the inputs with diodes etc.

Doepfer connector has 5v. I used the Synovatron proto kit, and cut a trace to get 5v distributed around the board.

Digital in = simple - easy to read pulses and act on them
Analog in = simple, you have 1024 levels of precision in theory, but I wouldn't expect anything like that in practice, but knobs and simple voltage control should be OK
Digital out = really simple. You should buffer/boost the pulses, but not totally necessary
Analog out = tricky with any precision. Quantizers and midi/cv modules are usually built around micro controllers like the Atmel, but coded properly, and using proper d-to-a converters.

MIDI is actually simple because it's just serial data, which Arduino can read. The circuit on the board is just protection (for your synth/keyboard/MPC) and inversion.

This is very cool!

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

Well done!

That's great feedback - I'll consider adding improved 5V support on-board when I design the Rev2 version of the Synovatron DIY kits later this year; perhaps by just having a few user-configurable busses.

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

Would be a great idea. I got started in this after going to a Tom Bugs workshop in London.

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).

Cheers
Tony
