picoDetector – A metal detector implemented on a PIC12F863

Remember that black tweeting apparatus security guards use to scan for metallic objects? Its called a metal detector for obvious reasons, its actually based on the concept of inductance. The inductance of an inductor is dependent on the permittivity of its core; by changing the composition of the core one could change the inductance of the inductor. Its from this concept that Bruno Gavand based his version of a metal detector using a PIC12F863 and a 330uH ferrite bead he calls it the picoDetector. The picoDetector’s firmware was written in C using Microelectronika’s MicroC Pro and is compatible with most PICs. Continue reading

TB-007 Metal Detector – The Mighty Treasure Detector!

You’re having a relaxing vacation with your family at the beach and having a nice sunbathe. Suddenly, a strange robot is approaching you. You’re curious and think, “Hmm…, it’s impossible to see a robot in the beach, unless there’s something important mission or secret is going on here!” So, you quickly bounce up from the beach and follows the robot… Isn’t the above incident sounds like a little bit adventurous for you? Well, guess what! You can make the above fictional story becomes reality, by simply getting yourself into this amazing project, “TB-007 Metal Detector”! The TB-007 is a smart robot that equipped with a metal detector. You can use it to locate those hidden treasures on the beach, forests or deserts. There’s a wireless camera attached at the front top of the TB-007, which is allowing the user to monitor the bots treasure-hunting progress from the comfort of his deck. Furthermore, the camera is mounted to a servo, and has a Laser pointer attached at the front of the robot for detecting purpose! By the way, TB-007 is an… Continue reading
