These Wi-Fi enabled speakers are an inexpensive way to easily set up a whole-house music system without breaking the bank or fishing wire through the walls.
We’ve shown you how to build a Wi-Fi radio before–here and here. This build, by contrast, is much simpler. The core of the build is a Arduino chip with a Wi-Fi and music module patched into the speaker inputs. You stream music from your primary computer over your local Wi-Fi network and all the speakers within range will automatically play the stream.
The upside to the project is that it’s simple and pretty cheap to pull off if you already have some speakers to hack. The downside is that, in the current incarnation, the sound quality is on the lower end of the spectrum. Hopefully future tweaks and upgrades will yield a higher quality sound with the same ease of construction and price point.
