Fresh hacks every day
We don’t have much personal experience with DOF hardware, but this Arduino library which reads and compensates for three-axis magnetometer and accelerometer data looks very impressive. It should work for existing hardware, but there’s also a demo design using a Honeywell HMC5883L compass and a Freescale MMA8453Q accelerometer which you can build yourself. Unfortunately these come in QFN packages (like … Read the rest
[Quinn Dunki] just reported in on the latest iteration in her computer project which is called Veronica. This time she added RAM to increase the VGA performance of her build. Like just about every other part of the project, [Quinn] knew what she wanted to do, but had to overcome a lot of issues along the way.
The goal is … Read the rest
This Lego watercraft uses drinking bottles as pontoons arranged in a pattern that make it look very much like a Water Strider, the insects that dance on the surface of a lake.
After the break you can see a video of the rig gracefully navigating a local pond, along with a raft of ducks. It’s quiet enough not to … Read the rest
So a man walks into a Radio Shack and the clerk says “Why the long face?”. No, that’s not it. [Ms3fgx] walks into a Radio Shack and says “holy crap, that PS3 IR dongle is only two bucks”. He’s been looking for an IR remote receiver to use with a Linux machine and decided to bend this PS3 dongle to … Read the rest
Maybe it was a language barrier he ran into, or possibly an inclination to do things the hard and smart way, but we really like [Alessio]‘s take on building the display for his word clock. Instead of relying on a pre-designed word layout, he made his own word pattern with a genetic algorithm.
While looking at other word clock … Read the rest
It’s surprising what lengths people will go to in order to bring functionality to their smart phones. In this case, [Tadpol] wanted a way to develop for his Arduino on an iOS device like an iPad or iPhone. He figures it’s possible to rewrite the IDE as HTML5, but since that’s a pretty large mountain to climb, he started by … Read the rest
[Gary] sent a few pictures of his latest project our way via Flickr, which we thought a few of you CNC owners might be interested in. He has been working with his CNC machine a lot lately and decided it was about time he built a touch probe for his rig.
His initial goal was to use the touch probe … Read the rest
