Colorino Battery out in AM Radio.wav

Electro-magnetic interference from the Colorino Talking Color Identifier and Light Probe when held near the internal Ferrite antenna on the back right of a 13-year-old boombox near the bottom of the AM broadcast band. You first hear the device inactive being brought near the radio with a bit of computer EMI in the background. This gives a low buzz of stacato clicks. At about 00:08 I remove one of the tripple-A batteries and the pulse-train quickens, rising in pitch briefly, then diesels out to a few clicks and you hear a thump. At 00:10 the battery is reconnected and you hear the white noise that means the device is in standby, which usually happens if you've just used it or inserted the batteries.
