Arduino Space Program

With the recently proposed cuts to NASA, our friends across the pond (in Northampton UK) decided to take action with a space program of their own… at least at a miniature scale. NortHACKton, a hackerspace in Northampton decided to host a rocketry day consisting of rockets powered by chemical reactions, pressurized water bottles, and even one that employed an Arduino controlled launch system, akin to a few we have seen in the past. It essentially consists of a countdown and automated ignition system. Schematics and source code are available for those adventurous enough to embark on missions of their own.

3 camera booms for your Wednesday afternoon

[Andrew] tipped us off about his Cable Cam built out of some lumber and clothes line. It is small enough to fit into a backpack,  includes a safety line and the camera can pan and tilt. A future version is planned with a small remote motor to move the trolley more effectively.

[Andrew] accidentally linked us to his other Camera Crane, taking the same ‘cheap yet effective’ approach as his Cable Cam. Once again, just some lumber and creative engineering are used to pull this one off.

For those without the ability to weld, check out [Bill Van Loo's] all wood version of a Camera Crane. Same parallelogram design, without remote video output or central pivot.

Programmable Game Boy cartridge walk through

We looked at [Gerry's] PLCC based programmable Game Boy cartridge back in May and mentioned that he was working on a how-to video. He did quite a bit more than that. He’s made a PDF version of the instructions but went into deep detail with a collection of four videos on his YouTube channel. We’ve embedded all four after the break. They include an introduction and background about the cartridges, desoldering the ROM chip, preparing sockets and wire, and making the solder connections. Whether you’re interested in this particular hack or not, seeing [Gerry's] soldering practices make the videos worth watching.

Panoramic and spheric tripod rig

This simple yet precise build takes your camera for a spin in order to take spherical and multi-row panorama photographs. The rig mounts to a tripod, using two servo motors for motion, producing images that can be stitched together perfectly. An Arduino handles the hardware with an LCD interface for dialing in the settings.It’s not the cheapest way to get 360 degree shots but the example images are amazing.

Fankart and the HolyF***k!ted fan

Inspired by a ducted fan project to simulate lunar landers he had seen recently, [Charles Guan] decided to do the next logical thing and make a ducted fan driven shopping cart.  The first iteration had a bare prop mounted to the front of the cart. Steering was done by mounting a servo to the front wheels.  This ridiculously dangerous shopping cart can be seen in the videos buzzing around the halls and parking lots of MIT. The second iteration that has the ducted fan drive seems not only slightly safer, but somewhat quicker as well. He does mention that the prop shape isn’t really optimal for a ducted design, so expect future revisions to be everything you would expect from a fan powered shopping cart.

He has built a more practical mobile shopping cart, if there is such a thing, called Lolriokart. This thing probably deserves its own post as well as it is a fully drive-able shopping cart. You can see a video of it in action after the break.
