    BIG LED Clock project

    Dunno, but if you follow the link, the schematic is laid out to the public, no need for a password or payment or anything.  If you buy anything from that link it's the finished project.

    Sorry, was thinking of track lighting

    Guess someone is gonna have to buy one and reverse engineer it...

    Christmas Pin

    It says they use a CR927 which if you reference Wikipedia's handy dandy battery guide (http://en.wikipedia.org/wiki/List_of_battery_sizes) says that it's a 3V 30mAh cell (the blinky lights company says they use 2 in each brooch). My bad, I made the assumption that you knew we were talking about...

    Christmas Pin

    So, based on our conversation, I understand that you're saying it's impossible to have a nice bright christmas tree brooch that lasts more than a few hours without replacing the batteries? come on man...if you're not saying it's impossible...then how is it done? with 2V @20mA bright leds? a 12V...

    Halogen lamp flasher

    Aren't halogen lamps powered up by a cap. or ballast of some sort? (i.e transformer) that would mean there's charge and discharge time...would make it really hard on the hardware to be "flashing it" no?

    BIG LED Clock project

    I'd imagine that there's software that can draw the PCB...hours and hours in front of the PC I guess...but you would have gotten it done over a year ago!? :P

    Christmas Pin

    okay, found some specs that you two might find interesting... http://www.vishay.com/leds/miniled/ if you look at the "low profile" Red, Yellow, and orange they are all 1.8V @ 2mA Now a CR2016 Lithium Ion coin style watch battery is 3V...and delivers approx. 90mAh (according to...

    Christmas Pin

    I know it's a bit late, but better late then never :P use 3mm leds, and no, they do not take very much power...using a 9V is a bit overkill, but you won't notice it on the leds as they draw a very low amount of current...using a 9V battery would mean that your circuit would last a very very very...

    We would like to use a Basic Micro Or PIC to turn on and off 51 LED

    This is somewhat what I'm trying to accomplish...can you add any comments? assistance? http://www.electronics-lab.com/forum/index.php?topic=9409.0
