Fresh hacks every day
We see a lot of LED matrix projects. They're fun, and you can learn a lot of basic lessons during the build. But this one is out of the ordinary. [Rtty21] built an oddly sized, and sound controlled matrix shield for his Arduino. That's it right there, the shield is the large chunk of protoboard but you can just see the Arduino peeking up over the top of it. Now we say oddly sized because a 9x9 … [Read more...]
Clap On!... Clap Off!... was super awesome when The Clapper came out in the mid-eighties. Now [Mathieu Stephan] is trying to make the concept much more functional. He put together a controller that lets you knoch on walls to control things around the house. It's called the Toktoktok project and uses small boxes to receive user input and control items like lamps and computers. A piezo element … [Read more...]
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 … [Read more...]
If you haven’t yet wrapped up your Christmas shopping, you may want to consider building [AlanFromJapan’s] implementation of the ever-classic “Clapper”. With its theme song burned into the brain of anyone old enough to remember the 80s, the clapper was a wonderful device that certainly put the “L” in laziness. Looking for an excuse to play around with an opamp and microphone [Alan] … [Read more...]
[Patrick's] latest Instructable walks us though making a clap clap on / clap clap off type of switching circuit, similar in use to that sometimes popular commercial product seen on TV. He does this by using a standard electret microphone, half of an LM324 op amp, a voltage comparator and a PIC micro controller. The operation of the device is as simple as its wiring, the microphone picks up … [Read more...]
If you've ever tried to take pictures of yourself you'll know that it can be a pain. It's especially hard to get that perfect shot of your godly features when you're out of breath from sprinting across the room. OK, yes, they have remote controls for that. But what if you lost your remote or you just don't want to have to carry it? [LucidScience] put together a sweet, um, "hands free" … [Read more...]
