    Constructing Perpendicular Lines

    I learned this in 4th grade geometry back in the 70's, maybe in our computer graphics driven society this is no longer common knowledge. This process also determines the mid-point of your initial line. In a similar fashion, you can bisect an angle by placing your compass anywhere along one of the lines making up the angle and striking an arc and then repeating the process on the other line so the arcs intersect. Draw the bisection line from the vertex of angle to the intersection of the arcs.On a large scale, this process can be used to layout athletic fields, like baseball diamonds and football fields allowing creation of accurate right angles. The lines are replaced by a string between two stakes. The compass is replaced by a long string with stakes on either end.

You drive one stake into the ground and strike your arc with the other stake and the line pulled taut.

  • Lucas Carbide Lamp Converted to Multi Colored LED

    My father had one of these carbide lamps back in the 1950's (I'm sure it was even older) that was designed to wear on your head. He used it for coon hunting. It was dim enough that it did not frighten the coons, but bright enough to make their eyes reflect so you could see them in the trees. I'm not a hunter, but I was always fascinated by this lamp as a child; it had a little flint wheel to allow you light it.

    Solar powered electric fat chopper bike!

    I need to move to New Zealand - you guys are so creative, it seems as if every other Instructable I find interesting comes from somebody in New Zealand.

  •  Generate Electricity Using Footwear-Charge Your Mobile(Piezo Generator)

    This is actually quite clever, however, I don't suggest wearing these while going through security at the airport. You may even want to avoid packing them in a checked bag!
