Fresh hacks every day
Okay, the kid does have a face, but it looks like Dad blurred it for his protection. The real story here is the killer ride built by his engineer father. It’s far nicer than the cars driven by the Hackaday team, but then again, since it cost more than a BMW 3 series that’s no surprise.

Building a violin by hand is no easy task, but constructing one out of carbon fiber is an amazing feat! Carpenter [Ken] had never made a violin before, nor built anything substantial out of carbon fiber, and he figured the best way to learn was by doing.
He spent a good bit of time measuring and drawing out his design … Read the rest
This doesn’t have the flashy futuristic appeal that we’d like to see from high-tech robots, but this amphibious wanderer is well suited for it’s intended purpose. It was developed by researchers at the University of Minnesota to navigate mostly wet environments, collecting data about water quality as part of a distributed army of sensor bots.
The two little arms sticking … Read the rest
There are so many good things about [Jose Julio's] robotic spider. It’s design is dainty yet robust, and the behaviors encoded in the firmware are nothing short of spectacular.
The body is built from a piece of balsa wood in between sheets of carbon fiber. The legs are carbon rods, using two servo motors for left and right leg … Read the rest
If you’re thinking of working with carbon fiber this guide should be a big help. The example is aimed at the automotive crowd but the principles transfer quite easily. Carbon fiber parts are constructed in a similar manner as fiberglass parts. A mold is covered in a release agent, the fibers are put in place and covered in epoxy. With … Read the rest
Finally, an answer to the problem of sidecar dorkiness. [François Knorreck] spent ten years hand crafting a sidecar with a beautiful design and a luxurious interior for two. The frame is aluminum, the body is mostly carbon fiber, and there are countless details such as automatic chain tension control and steering for the sidecar wheel that make this more than … Read the rest
I was looking up some construction tricks and ran across this little gem. Vacuum bagging is used to compress/remove air from resin/fiberglass/carbon lay-ups. This setup uses a common refrigerator pump with some plumbing to create the constant vacuum necessary.… Read the rest
