What will it do? My final project is a guitar amplifier combined with a sound pad. So the functions are amplifying guitar sound and playing sounds f.ex. drum beats or chords. The amp itself is not so complicated, I’ll base my amp on schematics for small practice amps. The sound pad is a bit more complex. I’m using capacitive sensors for the board itself, using Ardrumo to convert serial information to midi, and using Garage Band as a library for sounds. The sounds will be sent to the sound pad using bluetooth connection.
Who's done what beforehand? There are endless websites with information and videos on amp building, ranging from professional tube amps to tiny solid state amps f.ex. this.
There are all kinds of sound pads out there with different sensors and different functions. To start with I have been using ArduinoNano to program buttons and sensors and connecting them with Garage band. Something like this
Matt Keeter made multiboard that would work for myd esign with some modifications and then I’ve been checking out the board made by Matt Blackshaw found here
What will you design? I’m designing the guitar amp chassis, the controls and buttons and the sound pad. I’m modifying pcb boards and electronics that others have designed for the amp and sound pad.
What materials and components will be used? Locally resourced wood, from a forrest outside my town. Aluminium for the brackets and control panel of the amp. PLA plastic for the buttons.
Where will come from? Everything I need for this project I can source locally except the speakers that I ordered online. What I didn't find in the Fablab I caould get from the electronics department in the highschool where the Fablab is.
How much will they cost? The speakers cost just over 200$.
What processes will be used? I'm using the Shopbot for milling the wood, the Roland MK400 for the circuit board, I'm 3D printing buttons, moulding silicon buttons and laser cutting plexy.
