Project by Jeremy Fryer-Biggs
This project combines our love of music with our love of design and showcases the Microfactory's ability to mill woods and etch circuit boards. We created a custom circuit based on MAKE's "Cracker Box Amp" and a beautiful walnut and birdseye maple housing. This speaker is not only functional enough for your next outdoor BBQ with friends but sexy enough to fit in to the most refined decor.
You will need an engraving bit for making the circuit board and a 1/8th downcutting bit for milling out the sides of the speaker casing
We started by drawing inspiration from this MAKE design. After doing a little parts research we laid out the basic circuit design in Eagle
Next we exported the file as a .dxf and imported it into CAMBAM to create our toolpaths
Then we routed the design out of PC board
(A short video of the machine routing the board)
Once we removed the finished board, we soldered on all of the components
Next we designed the outside. First we created a CAD model using what we knew about the board that we designed and the components we selected
Then we exported the individual part files to CamBam
We milled out the top, bottom and sides in 1/2in walnut
And the front and back in 3/16th birdseye
Finally we assembled all of the pieces
Glued it together
And voila a beautiful working speaker that can connect to your mobile device!
