They haven’t figured out all the values yet, but this is only the beginning. How long until we see some mac/pc games that can use the Wiimote? I2C 101 posted May 11th 2011 8:06am by Kevin Dady filed under: how-to Embedded Labs has come out with a very detailed I2C 101 tutorial , that you should check out if you have any questions on the system. I2C is a short distance serial interface that only requires 2 bus lines. Keep in mind that as wires go down complexity goes up. While there are more than a few I2C devices out there in the wild, and the 2 wire system does make wiring a breeze sometimes, the information required to make use of it often seems confusing to someone who is just starting with it. The tutorial covers basic theory, stop / start conditions, addressing, data transfer, and acknowledgment plus illustrations. A couple of specific examples are given in the form of a 24LC512 serial eeprom, and a DS1631 digital thermometer complete with code. SparkFun product used for immoral hacking posted Nov 23rd 2009 8:00am by Jakob Griffith filed under: news While we have our fun ethically hacking, its very easy to forget that sometimes our ideas could be used with malicious goals . Take for instance SparkFun’s BlueSMiRF – the device’s original intention is simply to act as a wireless serial cable replacement. After hackers discovered several PIN pads use a serial interface, they put one and one together to steal several hundreds of people’s personal bank accounts. It seems SparkFun is getting a lot of heat lately , but we’re glad they stand up and address these issues. You can check out the original news clipping here . LED Dog Collar posted Feb 11th 2011 7:10am by Kevin Dady filed under: led hacks LEDs make everything better, right? What about your dog? [Ken] tries it out on one of his frisky dogs who loves to run whenever she gets out with a LED dog collar . It’s an off the shelf dog collar sporting 5 blue LEDs, and is powered by an attiny2313 micro controller, which makes adding / changing light sequences quick, easy, and also allows for future upgrades. Small PCB’s are made and to help keep minor amounts of the wild from frying. the electronics parts are encased in hot glue, and the whole thing is powered by 3 AAA batteries. While it’s an early test of the device, and there is more to come, like an automatic trigger as [Sunshine] bolts for the door, but it seems like a great help while chasing after a runaway dog in the dark. Join us after the break for a quick video. Kid-friendly RFID media center playlist control posted Mar 15th 2012 2:19pm by Mike Nathan filed under: arduino hacks , home entertainment hacks , news While young children have the tiny hands and fingers that most hackers/tinkerers wish they possessed from time to time, their fine motor skills aren’t always up to par when it comes to operating complicated electronics. People are always looking for ways to make their home entertainment systems accessible to their kids, and [Humpadilly] is no exception. Much like some of the other hacks we’ve seen this week , he has devised a way for his little ones (1 and 2 years old) to control his Dreambox Media Player using RFID, which seems to be the go-to technology for this sort of thing. His RFID remote consists of three major components aside from the media player itself. An Arduino runs the show, and is connected to both an Ethernet shield and a breakout board fitted with an ID-20 RFID reader module. The Ethernet shield allows the Arduino to talk to his Dreambox over a telnet connection, while the RFID reader does what you would expect. The device is in its infancy at the moment, and while [Humpadilly] hasn’t published a ton of details about the actual RFID devices he is using to control the system, he says that more details and improvements are forthcoming. In the meantime, you can check out his code here. (c) 2014 hackaday.com. All Rights...
