GeoPhone Sensor
by admin on Oct.09, 2009, under Equipment
My friend Andy commented on my GeoPhone project and mentioned that the sensor and kit are unavailable currently. I’ve been curious how that sensor actually works. I knew there was a magnet and it felt ‘suspended’ since moving it makes a noticeable ‘clicking’ sound.
I found this cool diagram describing how that sensor works. Looks pretty simple, I wonder how hard it would be to make.. I’m guessing the tough part is getting the right frequency.
