Hah! Looks like LED “Art Object” is the new LED throwie!

Kit consisting of a small 3V BR2032 Lithium battery, a 10mm clear lens blinking red LED and a small rare earth super magnet. No soldering necessary -Just connect up the LED to the leads of the battery. Use clear tape (not included) to attach the super magnet to the battery. You are now ready to throw your miniature bright red “piece of art” onto any steel structure where it will flash for days. Complete with magnet, LED, battery and diagram.

    I wonder if this could be combined with a small joule thief circuit to extend the lifetime. And to slow down the blink so there’s a brief blink once a second. Should be able to get several weeks out of it then.

    What’s this now? Some absurd kind of “how to waste batteries”?!

    Phil is JUST LEARNING that 90% of all art is a ‘waste’ of something. That’s why art is subjective Phil. Not to mention, that in bulk the batteries are cheaper than the LEDs, so in reality Phil, it’s a waste of LEDs for this particular form of art. As with all art, if it grabs attention and turns enough heads, it’s worth the time & money.

    Yeah, Phil, you big dummy!

    I’ve got this new art project I’m working on, it’s where I save up all my garbage for the week and then I stick it up on various walls around the city. You should see the looks it gets! Really makes people think.

    Keep your city wacky! Turn the system on it’s head! Stick your crap all over the place!

    The LM3909 was a really neat LED flasher that worked with one capacitor and one 1.5V battery. Too bad they’re out of production. Here is a website with some schematics and a discrete version of the flasher based on its internal schematic:

    Some NOS chips are found thusly (slim pickings):

    I don’t think a surface mount version was ever built.

    Any good mods?
