Make a mini boombox with your Raspberry Pi #piday #raspberrypi @Raspberry_Pi

NewImage

ThisOldGeek made a great DIY mini boombox using a Raspberry Pi. Check out the full tutorial on his site.

This project had its origin a couple of years ago. I received a nice tin box with a plastic window on the front. The window just screamed out for a special display project of some kind. The box had “Day and Night Sampler” (D&NS) embossed on the front. Thus, the name.

I decided this would be a good box to hold a small prototype of a boombox that I wanted to build, complete with Vacuum Fluorescent Display (VFD), a super-nice glowy character display. You could use a character LCD or OLED display instead of the VFD, but you’ll have to figure out how to adapt the python scripts for your particular display.

Features:

  • VFD character display 20 chars x 2 lines
  • Raspberry Pi attached to small amp through USB Sound card
  • IR Remote Control: Volume +/-, Playlist up/down/change, etc.
  • Internet WiFi Streaming of stations or play from stored playlists
  • View Now Playing Song Info, Date/Time, or Weather

Before Starting This Project:

This is not a good learning project for people brand new to the raspberry pi or hardware in general. You should have experience with:

  • Basic soldering and electronics
  • ssh/scp
  • Debian Linux
  • Software installation
  • nano or vi editor
  • a Dremel or hole cutter
  • a drill

This is a long build, but if you have the required skills, not a particularly difficult one. Working straight through these steps, you should be able to get a boombox like this built over a weekend.

Getting Started
I started with the tin enclosure and gathered enough materials to see if my project idea was feasible. After measuring and testing a rough fit for the speakers, VFD and raspberry pi, I had enough confidence that the project would work and things would fit.

Stereo 3.7W Class D Audio Amplifier – MAX98306: This incredibly small stereo amplifier is surprisingly powerful – able to deliver 2 x 3.7W channels into 3 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, its incredibly efficient (over 90% efficient when driving an 8Ω speaker at over a Watt) – making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic “LM386” amps! Read more.

Mini Remote Control: This little remote control would be handy for controlling a robot or other project from across the room. It has 21 buttons and a layout we thought was handy: directional buttons and number entry buttons. The remote uses the NEC encoding type and sends data codes 0 thru 26 (it skips #3, #7, #11, #15, #19 and #23) to address #0. You can use this to control something that is expecting NEC codes or you can pair this with our IR remote receiver sensor. Read more.

Adafruit Perma-Proto Mint Tin Size Breadboard PCB: Making a project that will fit into a “Altoids” Mint Tin? Put down that PCB shear and pick up a Perma-Proto in the new exciting minty shape!

Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype – usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That’s when we realized what people would really like is a proto board that makes it easy! Read more.
