As promised, we continue our series on new uses for Das BlinkenBoard. This month, we feature an amazing and simple mod by adding a Hall-effect sensor, a 2K resistor and a new programmed chip, they have turned the mild mannered Das BlinkenBoard into a magnetic field detector! It uses the LEDs as a bar-graph to display both relative field strength and magnetic pole polarity of magnets held near the sensor.
