  • About this: "The LilyPad MP3 Player’s headphone jack is safe for headphones, but don’t connect it to an external amplifier unless you’re using a battery to power the LilyPad. (The fine print is that if the audio ground is shorted to the power ground, the audio decoder chip will be damaged)."

    1. Why does this happen, and
    2. How can this be avoided or resolved?
    3. If there's no workaround, would I run into the same problem using an UNO R3 and the VS1053 MP3 shield?

    I'd like to use this in a non-clothing installation with powered speakers, but it's a wash if it has to be battery powered to work.

No public wish lists :(
