Digital Reversi Board Project

    This Digital Reversi Board Project by Hanting Lu and Kai Wang from Cornell University look like fun. It is just like the real reversi game and ensures that players can’t make invalid moves. An Atmel Mega 1284 is used to read in the press locations from the touch sensor and is also interfaced to the bi-color LEDs using a TI 3 to 8 line decoder chip and a

Raspberry Pi using LEGO MINDSTORMS Sensors

  If you have a Raspberry Pi you can use your existing LEGO MINDSTORMS Sensors. Thanks to John Cole from Dexter Industries for sharing this with us. “This is also a great example of how to get started with I2C on the Raspberry Pi.  We chose the dIMU because it’s easy to access and use, with just four lines to connect (SDA, SCL, GND, and VCC).  You may have to

Inside a Keurig B40

  If you want to hack a Keurig B40 the first thing you will need to do is get inside. As we can see by the video that Jared McClenahan sent in that is easier said than done. Gone are the days when things were made to be taken apart and fixed. It doesn’t look like these machines were made to be taken apart after the main housing assemblies were snapped

How to Build a Tiny Surveillance Spy Bug

  Dazaro3 shows us how to make a Tiny Surveillance Spy Bug in this video.  Dazaro3 makes the PCB using the toner transfer method. Since the board is very small (9mm X 9mm) and the parts and even smaller assembling the thing looks very difficult!  The result is a super small device though. “Parts used: Home made PCB ,9mm X 9mm SMD 2N3904 transistors x 1   (All capacitors and

Remote Controlled Car using Carambola

    If you are looking for a new remote platform Carambola might work for you. The Carambola Core is a small module that is only 35×45 mm (larger if you use the development board), open-source and Linux friendly. It allows for simple wired and wireless networking capabilities to connect to everything around you. This Remote Controlled Car takes full advantage of this to allow this car to be driven
