    If it’s lead free, it should be fine to continue brushing your teeth with, no? I find that the flux helps break down tartar in some of those hard to reach places.

    A devoted man of science, Mr. Robert is driven to find an electronic breakthrough that can solve some of mankind’s most challenging medical dilemmas. Rebuffed by the powers that be, he decides to make himself the subject of his own experimental treatments, accidentally unleashing his inner demons along with the man the world would come to know as DJ. SparkFunkster-Flex.

    I eat LEDs for breakfast.

    I’ve done that sort of thing with male headers in a pinch, but it isn’t ever pretty.

    What kind of diodes are these that cost $2? IN4001’s will not suffice?

    A very nice flyback diode configuration for this motor driver: http://www.instructables.com/id/Using-the-Sparkfun-Motor-Driver-1A-Dual-TB6612FNG-/

    and here is a demo of my use of the circuit: http://vimeo.com/61068377

    The guide has a bug in the motor circuit 12 on page 64. The original version had a 10k resistor, which brought the affects of this bug out even more. This version uses a 330 resistor, which appears to work, but still cuts the full use of PWM.

    Pin 9 should run directly to the BASE of the transistor and then a 10k pull-down resistor should be used running from the same (PIN9/BASE to Ground). See: http://bildr.org/2012/03/rfp30n06le-arduino/

    The way it is setup on page 64, a 330 resistor runs between Pin 9 and base.
