D&T Lesson Idea: Origami Windmill

Materials:

  • 1x Skewer
  • 1x Straw
  • 1x A4 piece of paper
  • 300mm of sticky tape.
  • Some type of box

So the challenge is to build a wind powered device that lifts a pencil/pen the height of a desk. The fan is placed 500mm away with 3 speed settings. Ideally you want your design to work on the lowest fan speed. Sounds easy, but that’s because you’ve already seen my solution.

It seems like Holden used crappy paint as I’ve noticed other VT Commodores have the same problem with the paint flaking off around the door handle. When I was sanding them, it didn’t look like there was a proper primer on there.

Comparison in size against my HTC Touch Pro

This was an impulse buy off Catch Of The Day for $150 but it has some neat features. Mainly being that it can record in full HD with a resolution of 1920×1080 @ 30 fps. It also has some timelapse features and the ability to take photos. It can also record at 1280×720 @ 60 fps.

Below are some test videos showing the difference between 1920×1080 @ 30 fps and 1280×720 @ 60 fps. I prefer the look of the 60fps. I don’t think youtube really shows the difference as they’ve been re compressed but I’ve added the raw MP4 files for download.
