In the microcontroller world some things are a bit tricky to do without some help. This can be some code libraries that help us talk to an LCD display, or communicate via some of the new serial protocols such as one wire. Elektronika.ba has done some work to help everyone out who wants to interface a microcontroller to a GSM phone. Thanks for making the English version for us. 🙂
This video shows 3 ways to open a door, first 2 will give you the been there done that feeling. The 3rd is fantastic, using a Wimote the user simply gives his wrist a flick to unlock the door! Here is the project link, and here is the translated version. Video after the jump. “DIY doorlock system via FreeBSD6.2 + Bluetooth HID stack + libpasori. To authenticate a user, this
Don’t throw away your old HP ink-jet printer, Seyed Bidoki has developed a way to print electronic circuits with it. “A desktop printer loaded with a silver salt solution and vitamin C has been used to produce electronic circuits. The UK researchers behind the feat say their experimental device could pave the way for safer and cheaper electronics manufacturing. PhD student Seyed Bidoki loaded a standard Hewlett Packard ink-jet printer
Ferrofluid is cool stuff, Sachiko Kodama and Yasushi Miyajima have built a spiral that demonstrates the beauty of the liquid. Video after the jump. “Morpho Towers–Two Standing Spirals is an installation that consists of two ferrofluid sculptures that moves synthetically to music. The two spiral towers stand on a large plate that hold ferrofluid. When the music starts, the magnetic field around the tower is strengthened. Spikes of ferrofluid are
I love the concept of these computer controlled eyes, I think this technique would be great at Halloween and Christmas. Have a full size figure in the front lawn that watches everyone go by. “The eyes are made from large pizza boxes cardboard and rolled by RC-servos that are controlled by an ATTiny2313 that’s connected to the PC using the low-speed software usb stack. The camera is connected using USB
This marble machine that Matthias made is a great example of a nice complex wood working project. I love the hard drive platter that is used as a bell. 🙂 “I started experimenting by cutting a circular piece of plywood, and drilling 4 holes into it at a slight angle. This I temporarily jigged up with some blocks of wood, and started turning it to see how well it would
Looks like there might be a breakthrough in x-ray technology very soon. This article is from the free Electronic Products magazine that is one of the Hacked Gadgets engineering magazines offered. “Removing a major obstacle in the quest to build a tabletop x-ray laser that could be used for biological and medical imaging, a team of researchers at the University of Colorado at Boulder has developed a technique to generate
