This is a super simple and easily customizable little synthesizer. This is my first time using the Arduino and also with acrylic, both I found very fun to work with though.  This is also my first Instructables so hopefully I have explained this well enough.

Step 1: Part and tools

For the innards:

Arduino Uno
power source(I used a 9v with an adapter)
4- 5k linear potentiometers
200mm linear SoftPot(you can go smaller than this I just used this length because its what I had)
output jack
optional: Arduino holster(I had this made using a MakerBot) for easily removing the Arduino if you want to use it for something else.
all of this I was able to get off jameco.com except the SoftPot which i found at trossenrobotics.com

For the box:

Acrylic pane(found mine at Lowe's)
Weld-On 4(found on Amazon)

Soldering iron
table saw
router table
drill press
butane torch
Weld-on applicator bottle
<p>which holes does the speaker go into</p>
I made an instructable on this synth too. This is the Auduino based on Peter Knights sketch. Theres a small video on my instructable if someone wants to listen to it.
you haven't given all parts list. also couldn't find how to play this?
pretty cool, however for the guy who wants a Theremin there is a stripboard layout for one <a href="http://www.paulinthelab.com/2012/04/theremin-veroboard.html" rel="nofollow">HERE</a>
TO ME THIS LOOKS SIMILAR TO THE &quot;SIMIPLE GRAIN SYNTH&quot;, JUST FOR THOSE LOOKING FOR REFERENCE VIDEO / SOUND, EXCEPT FOR THE SOFT POT, WITCH, IN THE OTHER EXAMPLES WOULD BE ANOTHER POT, (sorry for the caps) did not notice, i am curious how the soft pot sounds myself, so some of your video would be nice to see as well! nice job on the acrylic's
DDo you have any links to any video or sound samples it would be interesting to hear it
Can you explain how it is played? I assume the round pots are used to change the sound, but do you use the softpot to play notes, like a theremin?
Nice job! Does just a regular linear pot work instead of a &quot;soft pot&quot;?
