Fresh hacks every day
Powerful graphics cards are pretty affordable these days. Even though we rarely do high-end gaming on our daily machine we still have a GeForce 9800 GT. That goes to waste on a machine used mainly to publish posts and write code for microcontrollers. But perhaps we can put the GPU to good use when it comes compile time. The KGPU … Read the rest
Here’s proof that you can build cool stuff with simple tools. This self-balancing unicycle uses an Arduino and a five degree of freedom IMU from Sparkfun to keep the rider upright. Well, it’ll keep you upright as long as you have good side-to-side balance. But that’s true of any unicycle, right?
The Raptor was built by [Nick Thatcker] who is … Read the rest
[Stephen] took the safe route when getting his Raspberry Pi to dim an AC light bulb. He didn’t roll his own outlet box with a mains-rated relay inside, going with a mechanical connection instead of electrical. By attaching a servo motor to the dimmer knob the RPi can adjust the light level without risk of electric shock.
He is … Read the rest
We’ve seen a lot of projects that let you control all of your devices from a smartphone. But this universal web-based remote control system looks like the most versatile we’ve seen yet. The project is called Webmote as the controls are served up as a web interface so that you’re not limited to say an Android device. The UI can … Read the rest
Many if not most good hacks come from scrap or unused parts, but this hexapod robot takes it to a new level. [Helmut] wrote in to tell us about his ‘bot built from discarded electronics. As with most of the little walkers that we’ve featured here, this robot features some basic obstacle avoidance with a sensor array on the head … Read the rest
[MrBuildIt] has lived up to his name when it comes to this year’s Christmas decorations. He built a rig that spreads Christmas cheer from one end of the cubicles to the other.
In the demo video after the break you’ll see that the system is controlled by a nicely polished Android app. It lets you choose from three different … Read the rest
Here’s two photographic takes on the same subject, each with a different depth of focus. [Chaos Collective] came up with a way to make interactive still images that allow a user to adjust the depth of focus by clicking on different objects in the image.
This was inspired by the Lytro camera which uses an array of lenses to take … Read the rest
