This mbed RFID Tweeter project really shows off the power of the mbed microcontroller platform. With a relativity small program this project is able to read RFID tags and communicate with Twitter to send messages under specific circumstances. The mbed is based on an ARM processor, you can find the full impressive datasheet here (PDF). Video after the jump “Hardware Components For this example, we use: An mbed! An ID-12
Hacked Gadgets Forum user JingleJoe from England needed a power supply for his digital camera. I love that it was all built from bits and pieces laying around. I have used some creative heat sinks such as a section of an old junction boxes when free air was just not quite enough but I have never used a piece if a tin can. I will have to keep that heat
Matthias Paul Scholz made a cool Basketball playing LEGO Robot called NXTitzk, the name is based on a German NBA player. It can play in a user controlled mode or a fully autonomous mode. An ultrasonic sensor is used to judge how far the basket is so that the correct throw can be performed. If you would like to make your own have a look at the detailed build instructions
If you have ever set the wrong fusebit when programming your AVR have a look at this AVR Fusebit Repair Circuit which could help you repair the chip. There is also a parallel high voltage version to have a look at. Thanks Pawel “Did you make a mistake while programming fusebits, or purposely disabled reset pin (RSTDISBL) or ISP programming (SPIEN)? No need to buy or make inconvenient HV programmer
Here are a number of quick links from the email bag here at Hacked Gadgets. Thanks for sending in all your great projects and links to cool sites. iPod Touch Internet Remote Ham Radio Station LINK “Using an iPod Touch as a ham radio station from anywhere in the world (via WIFI). Cool combination of the old school & new school.” Thanks Victor. NXT Rover LINK “The idea was to
If you run a server room or have tons of computer equipment in your house you might want to keep track of the room environment. Invent Geek has made a Open Source Server Room Monitor project to help us do this on the cheap. “The server room environmental monitoring system is a low cost high performance device with the same onboard features as commercial devices costing hundreds of dollars more.
Colin Karpfinger who is also the creator of the cool Autonomous Paintball Sentry Gun has made a great article about Ordering your Eagle PCB Designs. Learning Eagle is quirky enough but after your design is done you still need to learn about circuit board manufacturing before you can get them produced. This is because the manufacturer needs specific files that represent the layers involved in making your board. After you
