DIY Synth: Auduino

This is a video of my Auduino prototype.

All audio, except for the echo, is coming from the Arduino/Auduino.

I have plans to build a ribbon controller that would control the pitch instead of the leftmost potentiometer. Of course a prettier enclosure would be nice too, the prototype was built into a carboard box.

Have a look at my build blog here:

Scematics and source code can be found here:

I ordered the pots and Moog style knobs from ebay.
Build cost was around 40€ including the Arduino itself.

"build a ribbon controller "

Like an ondes martinot?

[jjuup]

@horlacsd yes, or something more modern. I haven't toyed with the Auduino in many months... a WP-20 is the next diy project.. both need cv control.. :)

@jjuup Can it get over 16 mhz, cuz the Arduino is 16mhz by the way, what arduino did u use? Duemilanove? Uno?

[jjuup]

@NiekProductions Call it Lo-Fi and smile! I used a 2009 Duemilanove. Follow the links under "more info" to the google groups, join the mailinglist and check out the newest incarnations of the Auduino there, scales, creative enclosures etc. Check "Dave's Auduino" (google it) and read trough his blog carefully, It is well documented and very recent and fresh and has a lot of useful links.

can you use this with a keyboard?

[jjuup]

@RedDubplate I haven't bothered to try as I have some real synths, but you could follow the links I provided and see what kind of modifications are out there...

Very cool Jesse! Usually I'm not into these homebrew synths but this is very musical and nice sounding! Really good oscillator, the filter is nice.

My favourite part is the stepped pitch, which really gives it is musicality.

It'd be cool to have an A/B switch between the potentiometer and a ribbon controller to give both stepped and smooth pitch.

sounds very nice I like it a lot

@AKsib2 im wondering the same thing, please if you figure something out let me know.

[AKsib2]

how difficult would it be to add a midi port to control this synth? I'm looking in to making one

[stormsirens2]

basic stamp has the same programing as arduino?
