After many months of work, research and discussions, the latest iteration of our Slinky Seismometer Kit is now available. We’ve taken feedback from customers, and worked closely with Paul Denton, who has over 30 years’ experience in geophysics and education, to drastically improve the Slinky Seismometer Kit.
For those of you unfamiliar with the device, here is an excerpt from the description:
“Originally designed in association with the British Geological Survey (and Paul himself), our new and improved Slinky Seismometer Kit provides an elegant and low-cost solution to earthquake detection. The seismometer uses electromagnetic induction to detect ground motion and incorporates eddy current damping for improved sensing. Supplied in kit form, the seismometer is quick and easy to assemble, and you’ll be up and running in no time!”
We’ve taken the time to improve our original slinky kit, and as such there are a host of new and improved features. We’ve changed the outer casing to an engraved, rigid acrylic tube, which provides more stability and protection to the device.
We have an adjustable threaded top, for height adjustment of the magnet inside the coil.
There are now three adjustable threaded knurled feet, which allow you to easily centre the magnet inside of the coil.
Furthermore, we now have a dual coil assembly, with a 14mm magnet balanced between them. The coils have opposing directions, but are wired so that the detected voltage is cumulative. This allows for a greater sensitivity in readings but any interference is cancelled out.
As with our Build your own Seismometer Kit, we now have a small PCB with a 3.5mm jack socket, which allows for easy connections to your chosen seismometer interface.
The kit is available to purchase now, and for a limited time you can get a SeismicPi HAT, worth £48, for free! Just add the ‘Slinky Seismometer Kit‘, or the ‘Build your own Seismometer Kit‘ to your basket and enter the coupon code ‘EDUSEIS1’. Your free SeismicPi HAT will be added.
