Here share my latest project, a Wi-Fi Speaker.
This speaker is based on LinkIt Smart 7688, an open source development board that featured with Wi-Fi and Audio.
I made a wooden box to make the speaker look retro, wooden will provide nice sound as well.
This speaker has the simple hardware and shell, it won't be hard if you has some knowledge of electronic, any way if you want one, you can make it.
Here's a simple video to help you to have a overview of this speaker.
