LED Headlight

Tonight I did a much simpler version of this to turn a regular dim incandescent bulb into a three-led super-light. It did take some soldering, but the job was straight-forward (no “electrical” work was required).

UPDATE: This doesn’t work. Some “electrical” work is required. The bulb works for a mile or so, but dims and eventually goes out. I’m going back to incandescent.

‘Tis the Season Not to Have Enough Lights

I was putting up the christmas tree this evening and (surprise) all of last year’s light strands worked. However, when I string the lights each year, I realize that I have to continually readjust them until M approves of the light distribution. I thought, “self, there must be some calculus that could help me solve this problem”. So I did the geekiest thing I’ve ever done in my life… I built a “Christmas Light Calculator“. It’s based on Ken Muldrew’s Christmas Tree Calculator. Is the math correct? I don’t know, but 83.5156′ of lights sure seems like a lot!
