Geocaching is getting very popular. AJ and Brian sent in this cool Geocache Box they built with Invisible Infrared LED inside. This box has a secret number that can only be seen with a bit of ingenuity, in this case since the numbers are shown with IR LEDs the numbers are not visible to the naked eye. But if you look at it through the viewfinder of camcorder or
 Check out this new project called The Ard-Vark. If you know someone who is interested in getting into microcontrollers but programming is a bit daunting this system might be just the thing for them. Thanks for sending this in Kerwin and good luck with the project! “Kerwin Lumpkins wrote: Hello. A new kickstarter tech project for DIY folk that would like to add electronics and motor control to
Watch the video above for a nice description of what needs to be done to make a DIY laminar flow water fountain on the cheap. There are lots of different DIY designs and ideas from the community that are variations on this idea. See other ideas below. Kanal von Magicmastera has made quite a few videos documenting his Laminar Flow Water Fountain build process. The installation
Check out this DIY Android Portable Media Player that the guys over at The daily life of a DIY person put together.They took a cheap FM radio and hacked in an Android device to make it into a very functional media player. This reminds me a bit of the Chumby. I could see using this to listen to a podcast before going to bed and waking me up in
This Temperature and Humidity Sensor Project was built by Dave from Plastibots. The project was made to determine if Dave and his wife needed a new humidifier. Instead of going to Home Depot and purchasing a humidity meter he did what any resourceful geek would do, he built his own meter. This meter is probably more accurate than most store bought devices also thanks to the  Sensirion SHT11 sensor that
Randy Sarafan, the Technology Editor at Instructables built this programmable car platform by taking an off the shelf RC Car and swapped its brains with an Arduino. This allows the new car to have sensor capabilities and programmability. Randy installed a PING ultrasonic sensor in the front of the vehicle so that it can avoid running into objects but the possibilities are endless now that you can write code
 Check out this cool Self-Balancing Robot Build that Kerry Wong shared with us. He has used some very inexpensive parts to get this thing built. To read through the build process have a look at part 1, part 2 and part 3 of the build. “I used a LPY450AL for the gyroscope and anMMA8453Q for the accelerometer. These two devices are rather inexpensive and the IMU can be
