Summer 2012

Several classes were run this summer. A few projects were repeated for the new, mostly younger students, while some of our older students made the pendulum seismometer described in this previous post.

This is quite an advanced project. While we did spend some time on theory, such as the differing speeds of P and S waves and how their arrival times allow us to calculate how far away an earthquake was, we didn’t go into much more as it starts to invlove math concepts that are way above their level. However, as they learn more in school, I’m sure they’ll get much more out of it than most, since they will have seen those theories in action in the real world.

Cutting wooden pieces for seismometer base

How accurately can you cut to the line?

Using a mitre box to cut the moulding around the outside of the base.

Glueing the base

Sandpapering the base for a nice smooth finish.

Two part epoxy glue was used to glue the pendulum support to the base. (Best not to have nails near the magnet)

Cutting small metal parts for the seismometer pendulum

Varnishing the seismometer wooden parts

Assembling the electronic parts to put in the seismometer base


Setting up the computer software and testing the seismometer

 And within a few days, Richard had recorded this one with his seismometer sitting on top of a bookshelf.
