[Zoltán] sends in his very interesting implementation of a NumPy-like library for micropython called ulab.
He had a project in MicroPython that needed a very fast FFT on a micro controller, and was looking at all of the options when it occurred to him that a more structured approach like …read more
Sometimes you just gotta sit down and hack something together. Forget the CAD and the cool software toys; just hammer away until you have something working. That’s how [bobricus] ended up with this cute little laser engraver anyway.
For under $300 US of parts and a few nights working in …read more
[Dan Royer] is taking some inspiration from Prusa’s business and is trying to build the same sort of enterprise around open source 3D printable robot arms. His 6 axis robot arm is certainly a strong first step on that road.
As many people have learned, DIY robot arms are pretty …read more

[Aaron Christophel] writes in with yet another clever hack for his D6 Fitness Tracker. Using OpenOCD and Pygame, he shows how you can pull data right off the tracker’s screen and sent it to the computer.
This one appealed to us for its brevity. First [Aaron] launches the OpenOCD server …read more

[Ekaggrat Singh Kalsi] submits this interesting printer he built for his daughter to use. He admits that the project started simply out of curiosity about the strange deltesian movement. In this configuration, the X and Z-axis are a delta mechanism while the Y-axis is a regular Cartesian bed on rails. …read more

Controlling a single drone takes up a considerable amount of concentration and normally involves wearing silly goggles. It only gets harder if you want to control a swarm. Researchers at Skolkovo Institute of Technology decided Jedi mind tricks were the best way, and set up swarm control using hand gestures. …read more

The more we read about [Josh Pieper]’s quadruped, the mjbots quad A0, the more blown away we are by his year of progress on the design. Each part of the robot deserves its own article: from the heavily modified brushless motors (with custom planetary gears) to the custom motor driver …read more

Beau Ambur can often be found hosting hardware events and offering help all around the Bay Area. Now he’s turned it into a career and travels the west coast helping hackers and creators effectively leverage Kickstarter’s platform. Beau’s mentor session covers everything from, “is this project a good fit for …read more
The Giant Magellan Telescope doesn’t seem so giant in the renderings, until you see how the mirrors are made.
The telescope will require seven total mirrors each 27 feet (8.4 meters) in diameter for a total combined diameter of 24.5 meters. Half of an Olympic size pool’s length. A little over four times the diameter of the James Webb Space Telescope.
According to the website, the mirrors are cast at the University of Arizona mirror lab and take four years each to make. They’re made from blocks of Japanese glass laid out in a giant oven. The whole process of …read more
