| 描述： | Moving the Colorino around the light on one of the power strips on the floor. The LED on it is the weaker of the 2 I recorded from power strips. As with most AC LED's it has that crazy warping modulation. I discovered when I slowed these recordings down that these LED's do have an onoff cycle going on. I'll upload some of those sloweddown ones later.The Colorino Talking Color Identifier and Light Probe produces a tone when you hold down the light probe button. It's a pocket sized 2in1 unit, which is a Color Identifier/Light Detector for the blind and colorblind. The stronger the light source, the higher the pitch. The more light it receives, the higher the pitch. So you can vary the pitch by moving and turning it.Recorded from linein on my desktop using Goldwave. Lowpass filter was applied to lock out the 16khz sampling frequency. |
