For the lazy man who can’t be bothered to buy a proper wattage lamp here’s the Clever Clapper, a Clapper that finally has the ability to dim the lights.
Like the clapper we saw last month, [Pete]‘s version uses an ATtiny2313 and an electret mic. What sets [Pete]‘s version apart from the vintage 80s model is the ability to dim the lights. Like any clapper, two hand claps within a second toggles the relay. Clapping three times within one second puts the lamp into fading mode. In this mode, the lights dim up and down with PWM until a fourth clap is detected.
[Pete] saw that the program memory in his ATtiny2313 wasn’t 100% full, so he added a few more capabilities. If you shine a laser onto his circuit, a relay trips and turns on a decorative moon lamp. There’s also a ‘lecture mode’ that feeds the microphone directly into the microcontroller to vary the PWM signal. The result is a light that brightens with more intense sound. Check that feature out after the break after the demo video of [Pete]‘s Clever Clapper.
