Make these fun sound reactive speakers with Arduino. via instructables
My name is Charlie Schlager. I am 15 years old, attending the Fessenden School in Massachusetts. This speaker is a very fun build for any DIYer looking for a cool project. I built this speaker primarily in the Fessenden innovation lab located on our campus… This speaker can hung from the ceiling so to keep the tables clear. This speaker is built off of two other projects; A Dodecahedron Speaker for Desktop Printers and Sputnik 17 – 4 inch speakers. The two creators of these projects deserve partial credit for my version. This speaker took about 16 hours in total to build and wire. It is a great project to complete over the course of a week.
Ok so now for the instructions, I’m going to start of by listing the materials and tools required for this build. A laser cutter is very helpful for this project in cutting each face, but it is possible to cut the parts with a jigsaw. This build in total cost about $550, but can be made for much less if you buy cheaper speakers. I chose to buy expensive speakers to maximize the crisp sound this speaker delivers, but any 4″ speaker would work, you may have to adjust the amplifier as well to fit the power needs of the speakers.
Also, I would like to add that this is my second version of the speaker, the first version was 3d printed and wired with 3″ speakers that costs $2.00, so the sound quality wasn’t great, but the speaker worked and looked amazing. I also installed LED’s to that speaker.
