    I’d like to add my appreciation to that expressed by others. You have to strike a balance between meeting your legal operations and protecting the privacy of your customers, and IMO you went above and beyond by negotiating a reduction in the amount of customer records provided.

    Thank you

  • Tutorial - Processor Interrupts with Arduino | about 2 years ago

    Minor nit, your button_time/last_button_time code has integer wrapping issues. The interrupt will no longer do its work when button_time < last_button_time.

    I know that’s not the point of the tutorial, but people tend to copy code snippets like that, and that would be a real beast to debug. (button suddenly stops working after two months of operation)

    In the face of increasingly difficult Lost Viking puzzles, Baleog the Fierce turns to hardware development to give him an edge.

    Simpler to adjust yes, but far, far more expensive, you need 142 + 62 = 232 header pin pairs, and someone needs to attach all of them to the board…

    You distract the psycho farmer and I’ll bash him with this collection of foam clubs.

    Holy crap, skin-safe conductive paint? I’m staying tuned allright, I’m going to have to work hard not to hold my breath…

    The reclusive Kodama brings its creepy head-rattling skills to a classroom near you.

    Wow, I’m really blown away by this, the beginner angle is one thing, but particularly for the LillyPad kits, this looks like a really convenient way to go straight from prototyping your system to installing it.
    I’ve never had any real interest in E-textiles other than “huh, that’s neat”, but this lowers the barrier to entry so far that I’m brainstorming what clothes I have that I might want to make blinky…

    Actually you need to read what you quoted more carefully, it DOES matter where you place it, the extremely low current you quoted is only valid if the electrode provides a “direct pathway to the heart”. In other words these electrodes will only be dangerous at the current level you mention if they either contact a surgically implanted heart catheter or if they come into direct contact with the heart muscle, it is not at all reasonable to have the warning you propose.
    The warning BlackJester suggests is sensible, but really you could get the same effect by jamming a wire into your skin, these pads just make it more comfortable.
