Fresh hacks every day
The LVL1 Hackerspace held a hackathon back in June and this is one of the projects that was created in that 24-hour period. It’s a 3D scanner made from leftover parts. The image gives you an idea of the math used in the image processing. It shows the angular relations between the laser diode, the subject being scanned, and … Read the rest
[Jack Crossfire] took one of those inexpensive indoor helicopters and made it autonomous. He didn’t replace the hardware used for the helicopter, but augmented it and patched into the remote control to make a base station.
The position feedback is provided in much the same way that the Wii remote is used as a pointing device. On the gaming … Read the rest
The folks at the London-based startup GoCardless have a pool table at their office. Being the techies they are, they decided to build a system that automatically scores games. The results, while not fully complete, are still pretty impressive for something whipped up during a 48 hour hackathon.
The automated score keeper uses a webcam duct taped to the ceiling … Read the rest
Hackaday reader [Tom Price] often uses Skype to communicate with family near and far, but he was getting tired of adjusting his webcam each time his kids moved out of frame. While the solution he came up with isn’t fully automated, it is hands-free, which is good enough for his purposes.
[Tom] was looking around for an electronic foot pedal… Read the rest
[Jeremy Blum] wrote in to share his LibeTech QR Code Door Lock project. He developed it during his Senior year at Cornell University along with three of his classmates. It seeks to move away from magnetic card locks in favor of optical locks that authenticate based on a QR code.
The hardware he’s using here is definitely cost prohibitive, … Read the rest
The guys over at Section9 Hackerspace in Springfield, Missouri just finished building this treaded robot. Despite the juxtaposition of the cat, it really doesn’t defend anything. The project is a reconnaissance robot controlled over the network with video feedback.
The team started off with some lofty goals. They wanted to the robot to be able to climb stairs and … Read the rest
If you want to find out what something is made out of, you’ll probably be using a spectrometer. These devices allow scientists to determine what something is made of by shining light through an object and recording what colors are absorbed. Professional spectrometers cost many thousands of dollars, but you can build your own using a simple USB web cam, … Read the rest
