  • The datasheet lists winemaking as one of its suggested applications, so I guess the answer is yes. Datasheet here:

  • I don’t want to start a flame ware here, but only three countries in the world haven’t officially adopted the metric system. I know Sparkfun is in the USA, but even American engineers use metric. Ounce-inches? An online search tells me it’s 2.42 newton-meters, in case anyone was wondering.

  • Um, I don’t think there was ever a “panic” about an impending ice age in the 1970s. Not among climate scientists at least.

    In the 1970s there was a lot of discussion about ice ages and climate cycles. No informed source was sowing panic about an impending ice age. Even back in the 1970s we could do simple math, and we understood the time scales involved.

    The sheer speed with which we are putting CO2 into the atmosphere is orders of magnitude different from the timescales of ice ages, which is part of the reason there is concern.

    Note also that the idea of anthropogenic climate change due to CO2 is not new. I’d have to dig out the references, but this was being discussed 100+ years ago when scientists calculated net solar radiation over the globe as a whole.

    I hope I’m not encouraging the trolls by feeding them.

  • Can anyone tell me maximum output voltage of this thing? Right now I’m using a TL499a to stepup 6v to about 26v at 10mA… would this chip be able to do the same job? I’ve looked thru the datasheet and the application note and I can’t find this info anywhere, what am I missing?

  • I’m having similar issues, glad I’m not the only one.

  • Plasma ailerons? I’d love to know more, do you have a link?

  • The former Prime Minister of Australia, Kevin Rudd, was the first foreign head of state to address the Chinese Parliament in Mandarin.
    Sure it wouldn’t make or break a politician or businessman, but skills in foreign languages couldn’t possibly harm their chance of success.
    It’s probably not really called a parliament.

  • These will come in very handy, as will the spring terminal version that appears under “related products.” Standard pin spacing, excellent!

  • Is this class a general microcontroller and prototyping class that just happens to use the Arduino as an example, or is it specific to the Arduino? I know my way around the picaxe environment and am fairly competent with circuit layout in Eagle, but I am definitely keen to move toward the open-source goodness of the Arduino. Would you recommend this course? Is there something more specific coming up? It sounds like fun regardless!

  • Please raise your glasses to Frencil, who surely has more important things to do with his time, but has still made the effort to reply to so many of our questions. Free Day is awesome!
