    Whoa @ the clock that plays life!

  • Product COM-10966 | last year

    Yes, I’ve tried this - they’re too weak.

    HOWEVER - 8xC batteries & 8xD batteries work very nicely, and I prefer them to the lithium batteries that are seen in the product video (PRT-10470)

    I’m guessing that a PNP/pMOS transistor would accomplish this far more effectively than a reed switch of greater complexity. The PNP/pMOS transistor performs a logical inversion - thereby switching off when the reed switch is closed (conducting), and switching on when the reed switch is open (“off”).

    Sparkfun (and every reputable electronics supplier) carries both.

    p-Channel MOSFET (pMOS): https://www.sparkfun.com/products/10349

    the MOSFETs are better for higher current applications, but (speaking only for myself) are more slightly less intuitive for a beginner.

    Sparkfun - I’m going nuts trying to get these to work! Could somebody provide a nice tutorial/good schematics???

    I have a feeling it has something to do with the fact that the horns are a massive inductive load, but I don’t understand why that prevents a SparkFun li-poly battery + 5x 2.7v 5F supercaps, from driving it.

    I’ve tried using the 20A SPDT relay, but the tutorial is for a different relay, and I think the datasheet is - for lack of a better word - crap.

    Of course you’re gonna immediately think “BEEFCAKE KIT!!”, but I’d appreciate something more fun :)

    LOL – any idea where I can get one of [Air Horn/subway]???

    Also: Be careful about quieting parties with it. Certain parties might actually like it ;) http://www.youtube.com/watch?v=P6NoOFuvyq0

    edit: changed ambiguous “these” → Air horn/subway

  • Product TOL-10719 | about a year ago

    Buying this for my sparkfun soldering iron, was easily the best soldering decision I’ve ever made. This is better than the stock tip by an order of magnitude, of magnitudes.

  • Product TOL-10719 | about a year ago

    I bought this to replace the stock tip on my SparkFun soldering iron (TOL-10707). Buying this possibly was the best (soldering) decision I’ve ever made!

    It transfers heat better, is more precise, and is all-around a better soldering tip, by at least an order of magnitude.

    As long as they follow good procedure, who cares if it’s easier - it already takes just the “blink of an eye” - http://www.infosecisland.com/blogview/21043-Why-Security-Through-Obscurity-Still-Does-Not-Work.html
