This cool little Pocket Metal Locator is sensitive enough to identify small Nails and Tacks in wood and compact enough to fit into awkward spaces making it convenient to carry and use for metal locating.
The unit has four independent search coils and color LED indicators making it easy to cover a larger search area quickly while being able to accurately identify the target.
This neat little device is self-calibrating with one button operation, rechargeable through a USB port and uses color LEDs, sound and vibration to indicate target strength.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
