Lights on

This is getting a bit repetitive, I know, but the led light is still glowing brightly.

It's more than three weeks (500 hours) on the same batteries now, pretty amazing I'd say.

    You should be posting a graph of battery voltage and current over time. Also you should have comparative graphs showing battery straight into the LED vs running into a buck/boost converter into LED. eg: http://cappels.org/dproj/ledpage/leddrv.htm

    Controls should include an identical battery discharging into a constant current sink and one discharging into a constant resistance.

    "it's still running" indeed. :-)

  2. Hi anonymous

    I should do all that, but I'm a bit busy with other fun stuff.

    Cheers
