Fresh hacks every day
Why should cyclists have all of the fancy toys? Bicycle computers are very common these days but you won't find similar hardware for skateboards and longboards. [KobraX22] isn't taking it lying down. He built this speed and distance computer for his longboard. It doesn't use very many components and should be easy to install. The device monitors the rotation of one of the wheels by mounting a … [Read more...]
This is the bee counter which [Hydronics] designed. It's made to attach to the opening for a hive, and will count the number of bees entering and exiting. We're not experienced bee keepers ourselves (in fact we're more of the mind of getting rid of stinging beasties) but we understand their important role in agriculture and ecosystem so we're glad someone's making a nice home for them. Most of … [Read more...]
[Sebastian] wrote in to update us about the optical sensor project he started a couple of years ago. You'll find his most recent update here, but there are four different post links after the break that document various parts of his progress. You may not recall the original project, but he was looking to add resolution and sensitivity to the keystroke of an electric keyboard. With the sensors … [Read more...]
[Ben Peoples] works in theatrical electronics. Sounds like fun, and here's an example of the kind of stuff he does. We're not sure what event this installation was used for, but if the elevator ride needed something flashy just think of what the party room must have looked like. These HDTV screens on the ceiling of the elevator play different clips when the elevator is moving up or down. The … [Read more...]
[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the Arduino when an object approaches the sensor without the need for polling or extra code on the Arduino side of things. As you can see, a single chip on the board takes care of all the work. That's an … [Read more...]
You know you've got a good hardware platform if you can easily repurpose it with a code rewrite. And that's what [Eric] continues to do with these little Hexbugs. This time around he's bent the IR emitter and receiver downward to use as a reflectance sensor. This gives it the ability to follow a dark line on a light surface. He originally patched an MSP430 into the $25 RC toy. The IR pair was … [Read more...]
This mirror has a large monitor behind it which can be operated using hand gestures. It's the result of a team effort from [Daniel Burnham], [Anuj Patel], and [Sam Bell] to build a web-enabled mirror for their ECE 4180 class at the Georgia Institute of Technology. So far they've implemented four widget for the system. You can see the icons which activate each in the column to the right of the … [Read more...]
