introducing ADDAC System - arduino analog->digital->analog

[__ag]

Hello all,

so arduino meets 16bit 8 channel CV output
(this are NOT PWM outputs!)

I've been building this modular system for digital generation of complex waves based on math equations, this is also meant to be a platform to integrate the analog world to a computer for higher resolution applications where midi isn't precise enough, so it has a 10bit ADC (0-1023) and 16 bit DAC (0 -65535)
It is also a standalone tool, no computer is needed to run it, after the code is uploaded with all the functions assigned it's just another module on the cabinet

a truly open interface based on the arduino platform, with basic control through java programming and full control with c++

although it's not all finished yet, all electronics are assembled and tested, but still a lot more programming to do in the arduino library to make everything easier for low level programmers, still i thought of posting this here to get some reactions before making everything available.
in the next couple weeks a lot more info will be added to the site, including more pictures, demonstration videos and a lot more info

it's hard to describe the whole concept briefly
please take a look at:

soon it will be hosted here:

get in touch

Beautiful work... the panels look great.

Fascinating concept... is this, in essence, a modular digital synthesizer?

Thanks!

it is not a digital synthesizer itself, it does not generate any sound, it generates 8 channels of programmable Control Voltages to be connected and control any other modular synth module, as well as usb for computer connection through serial protocol, easily accessible through MaxMSP for example.

Heard some of what they can do live last night and I was positively impressed.
Keep it up

Thanks for the comment!


here's a couple new modules in the ADDAC System:

ADDAC501 Complex Random
ADDAC501 Complex Random Expansion

more info very soon*


all the very best

Very nice looking modules.

What dacs are you using?

Also what voltage ranges are supported?

[__ag]

16bit analogue devices dacs
for now voltage inputs from 0 to +10v, although i'm working on some side modules that will accept from -10v to +10v
