Sparkfun organized a day of Autonomous Vehicle fun at their Annual Autonomous Vehicle Competition. Via: Hackaday “Ground Vehicle Classes Each entrant will be classified by the judges as one of the following robot classes for their ground vehicle: Micro/PBR – Less than $350 total spent, or small enough to fit into box that’s 10″x6″x4″ Doping Class – Bring the biggest, baddest and most expensive vehicle you can make ($1k+
Google SketchUp is a free 3D modeling software. Using the steps outlined by Eric William you will easily be able to convert your SketchUp design to something that can be 3D printed. Eric used a Solidoodle printer but this will work on any 3D printer. First step is to export from SketchUp in an STL file format. The STL file is imported into NetFabb where it is repaired if
LifeBuzzN shows us How to Recover Gold from Scrap Computer Parts. This process involves dangerous chemicals so if you attempt it please use caution. If you have a look at the edges of most computer parts you will see that they are gold plated. In the video memory chip gold fingers are being used but you will find gold fingers on video cards, audio cards and many other parts
  Ugifer send this box of electronics 124,000 feet in the air. The view sure looks great from that height! To track the balloon he used the Space Near Us tracking system, a custom PCB was created to keep the circuit as robust and compact as possible. “Radio – in the UK there are only a few narrow frequencies you can use from the air and even then you
 Check out this Northrop Grumman X-47B RC Plane Build by Eric Maglio. “The internal structural parts were cut by laser from some 1/8″ plywood. They were assembled first, then glued inside the skins during the joining process. Much clamping ensured a tight fit. It was easiest to install the landing gear and doors next, while the model could still be rested inside the molds. All of the hinges
When laser cutting with most laser machines you can only cut straight down. How can we cut angles? Make a jig, Martin Raynsford from Just Add Sharks shows us how. “Here at Just Add Sharks, we’ve been running some experiments using these cutting jigs and the results are pretty promising. The first and arguably most useful jig holds the material at 45 degrees to the laser beam. The panels that
With a top speed of 58 MPH this Scratch Built Cargo Dropper RC Plane that ExperimentalAirlines built is no slouch. There is a video camera in the cargo bay so you can watch the cargo drop, there is also a camera mounted on the cargo so you can watch the cargo falling from the plane. Nice to see that the plane is primarily built from cheap foamboard and looks like
