Fresh hacks every day
[Mark] was playing around with a small GPS sensor when a light bulb lit over his head. He imagined it would be pretty cool to replicate one of Google’s Street View cars at a fraction of the scale using Lego NXT parts. He figured it would be easy enough to rig a few cameras to a remote controlled car, recording … Read the rest
[Chris] is quite the devoted tinkerer. He recently wrote in to share what can only be described as a labor of love. His Quad Delta Robot system has been in the works for about six years now, split into periods of research, building, more research, and rebuilding until arriving at its current form.
The system is made up of four … Read the rest
Smart people don’t put their toys away, they build machines to do it for them. Case and point: this NXT project which can sort LEGO pieces. Just dump a bucket of random blocks in a hopper on one end of the machine. One slice at a time, these plastic pieces will be lifted onto a conveyor system made up … Read the rest
[Bshikin] built a pinhole camera out of Lego pieces (translated). It is a fully automated unit thanks to the integration of the NXT pieces. It took a bit of careful calculation to get the film spacing adjusted to match the focal length, and quite a bit of tape was necessary to keep light out of the film chamber. … Read the rest
When [Dave] installed hardwood flooring in his house, he needed a solution to help automate the monotonous task of routine sweeping. Rather than go out and buy one of the many existing automated sweep robots out there, he decided to use his passion for LEGO Robotics to design and build a NXT based Swifferbot he calls Pulito. His version implements … Read the rest
Playing store just got really, really fun because you can now build your own LEGO barcode scanner. As you can see after the break, it works well and it’s fast like a real barcode scanner. Unfortunately it doesn’t scan real barcodes. Or at least not traditional ones. As we learned in the Barcode Challenge, standard barcodes are a … Read the rest
With 2400 LEGO bricks and a lot of patience, [Will Gorman] built a LEGO 3D printer. It’s similar to a RepRap or a Makerbot, but instead of extruding plastic, it uses pre-extruded building blocks (aka LEGO bricks). The grey wall extending far above the unit itself is a feed magazine which holds the raw material. A Java application takes … Read the rest
