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:
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)
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)
Weld-on applicator bottle
