AURSINC Atmega32U4 DSTIKE Development Programmable Bad USB Watch with 800mAh Rechargeable Battery | Distance Sensor | Laser | Buzzer| RGB LED | RTC | for Arduino Beginners

Exactly what it says it is. A wearable Arduino Leonardo pre-programmed to dump locally saved wifi passwords on plugging it in, and obviously, this is customizable. If you know exactly what you'd type if you were at their keyboard, it is extremely easy to program the board to do so. There's also a couple bells and whistles included, such as an LED flashlight (hold the power button for a couple seconds while it's on), a laser pointer, a short range laser rangefinder (0-1.2m), and a buzzer. All usable pins are defined on the store page and in the source code, and pretty much all libraries needed have clear sources if you read the user guide pdf found on the store page. (if you run into trouble with timer.h, install the library arduino-timer) A schematic is also provided if you want the whole circuit. A very cool beginners project!

This is a good watch but suffers from horrible battery life.

If it wasn't for this beautiful watch i would never have learned how to patch code to make it actually work.....void thanks (man)[ time.alot(to); to(figure) + to.figure(it); it(out) + (to, figure, it, out); end;]
