First Project

What was Relavak Labs first project???

A hardware based game called the Flashwand. The Flashwand displays text when waived in the air. It also can display a variety of colors and patterns from a crystal ball on its end. The programming contains an adventure (RPG) game that uses the display and the single pushbutton. As you play you earn more functions for the wand until you get all of the wand’s powers, and the ability to put program the wand to say whatever phrase you wish.

I used this project as my first foray into sub $100 development systems. A PIC processor, a 64kbit EEPROM, 10 LEDs, a pushbutton switch, a tilt switch, and a resistor is pretty much the entire hardware. The most difficult part was designing the hardware to fit in a very skinny aluminum tube. I built about 10 of them (have parts for 100) but can only find one or two.

This project lead to the creation of Sensys Networks (
