[ystoelen] created this modular wooden toolbox out of laser-cut 5mm plywood secured with leather hinges bolted into place. The leather strips secure the various tool boards with grommets connecting to plastic plugs. The toolboards use cross-shaped holes with laser-cut plugs and strips of elastic securing the tools, allowing each board to be uniquely configured depending on what tool is being stored there. There is a larger, “main” board, onto which smaller boards can be placed depending on what tools you’ll need.
While this is a clever approach to tool transport, we have some concerns about this project. Usually the problem with a box full of tools is that you’ve overloaded it and can’t readily lift it up. Often this involves a steel toolbox that won’t break, no matter what happens. But a plywood construct isn’t nearly that strong, and if overloaded or dropped it’s gonna take some damage.

If you’ve got an expensive bike and don’t mind carrying around a whole bunch of extra weight in your courier bag you’ll like this concept. A design team built a pole-climbing bike rack in about 14 days. The video after the break shows the prototyping process as well as the finished “lock” in use. It’s a commercial for the company that employs the designers, but this is one kind of advert we don’t mind watching.
Square channel makes up the body of the device, with a set of Rollerblade wheels which grab a light pole and use three 12V gear motors for climbing. The controller is a wireless fob similar to those used for keyless entry on cars. In the video you can hear the cliché sound of a car alarm being set once the carrier reaches its finished height. Nice.

[Karl-Engelbert Wenzel] developed a UAV capable of taking off and landing on a moving platform autonomously. The platform operates aircraft-carrier-style by driving around the room in circles. The quadcopter tracks a grid of IR LEDs at the front of the landing deck by using the IR camera from a Wii remote. The best part is that the flight controls and processing are all done by the copter’s onboard ATmega644 processor, not requiring a connection to a PC. The landings are quite accurate, achieving a maximum error of less than 40 centimeters. In the video after the break you can see the first landing is slightly off the mark but the next two are dead on target.
So build yourself a mobile platform and pair it up with your newly finished quadcopter to replicate this delightful hack.
