Today was the day of the project presentation and I am pleased to report it went very well!
As Lee was impressed that we had managed to get it working he let us use some Ferrofluid to create a large mass of it in our glass vile. This made the effect more visible and therefore way cooler…
What you are seeing in the video above is a random number generator pulsing the Ferrofluid into a spiked form. We also had it working from the number in the feed, but it didn’t vary pulse as the Ecoid data takes a while to change as they power ON/OFF from sleep out in the feed to conserve power.
Lee had also brought in a wireless Arduino set up that made the relay switch turn ON/OFF - depending on his heartbeat that was detected by a heart detector worn on his stomach. All we would have needed to do was link up our relay that was in turn connected to the electromagnet for it to work but unfortunately we ran out of 9V batteries with power!!
The thing about this project is that we have got it to a level where we could go foreword and make it bigger and better. Using a proper electromagnet that you could vary power and strength with a greater amount of Ferrofluid you could get some very impressive outcomes. Must admit it is an idea I am considering for the final project of this module. Would I be able to afford all that Ferrofluid though!?
