Instead of booking an MC for your next karaoke party, take a look at [Paulo]’s build that turns any iPhone into a karaoke machine.
There are thousands of YouTube videos out there of songs with lyrics – a much more advanced version of the mainstay of any karaoke get together, suitcase full of CDs and a video monitor. The only problem in turning these YouTube videos into a karaoke party is putting a drunken slob into the mix. [Paulo] recently solved this problem with a karaoke mixer that adds a microphone input to any analog audio feed.
But this is only halfway to a karaoke machine. To finish the build, [Paulo] created an amplifier (with a fabulous Manhattan-style PCB) for an iPhone’s audio output. The video output can be sent directly to a monitor, allowing for the full karaoke experience.
Since [Paulo]’s karaoke mixer uses an XLR jack for the mic, it’s still possible to make karaoke worse by adding vocal and other miscellaneous effects.
There is no XLR plug to be found in this build… only jack :)
Hi Koenzie. I’m the author. You are right; it’s a regular jack input. I believe that was a minor confusion on the hackaday.com staff part when writing the summary.
Confused about where the hack part is…
The jack coukd be TS, but if it’s TRS, then no problem making it an XLR.
Hackaday contest idea: ugliest functional circuit board.
