  • News - Free Day 2012 is Under Wa… | about 2 years ago

    It doesn’t update on the entry page, you have to come back to the homepage to get it updated… probably a bug.

    WOOT. Got one. Now to decide what I want. :D

    Yes, captchas suck, but scripts eating up all the $$ sucks too…. I kinda like the random picking idea, just something different.

    Good luck all, and thanks Sparkfun.

    Thanks for that link. That was really helpful for getting the components right. Far easier than dealing with the math myself. :) I did spot check it, but it worked fine. I built it, and my first switching regulator works great. 14V to 3.3V step down, now on to the XBee modules.. :)

  • Product PRT-09081 | about 5 years ago

    I won’t claim to know how it works inside, but the open circuit voltage is 8.5V. I think it has some kind of current protection built in as well. I put my ammeter probes on it directly and it registers about 2A for a second then cuts off.
    A datasheet on these things would be nice. I’d love to know the max current draw and details of any protection/voltage regulation circuit that might live in there.
    They are very light compared to alkaline. I have more testing to do, but I think these will make nice batteries for my rocket electronics. :)

No public wish lists :(
