Derrick read about our MonoBox Powered Speaker in the geek section of his Flipboard app and decided to build it in a weekend! You can see he added a switch and status LED near the bottom of the tin. Also clever is his input wire which goes into the first ‘o’ in Saronno, a town in the north of Italy known for their macaroons. I hope the tin is now powering tunes while he works on other projects in his garage. He writes:
I took the build list to RadioShack and a sales rep helped me find all the parts. When I got ready to build the amp I practiced my soldering skills on a circuit board out of a dead appliance then went to work. Once the circuit was all soldered and checked with a magnifying glass I added power and it worked immediately. I used a speaker out of an old TV. I also chose to add a switch and LED so I wouldn’t forget to stop the power when done using it. I ended up installing the setup in an old Christmas cookie tin that I have had in my shed for years. I always loved the tin and was pleased to find that it could be put to a better purpose. I marked out the speaker hole, drilled a hole in the corner, then cut the first L corner with a sharp knife. I then used tin snips to finish the job. I split some old medical oxygen tubing to go over the sharp edges then found old mesh wire to go over the opening. I cut the mesh to size and bent all the wire ends down, then marked a spot to drill a tiny hole for each wire. The mesh was then placed on and the wires were bent over on the inside. I next drilled holes for the speaker lugs, switch, light, and input jack. Once all the components were installed I attached the circuit board in the tin with double back tape. I placed a little batting in behind the speaker and then cut the foam for the battery and threaded the battery lead up through the foam. The project is beautiful, and sounds great.
