Well, it's taking longer than I expected for the parts for my
most recent project to come in. I'm waiting for some wireless
pigtails (U.FL to RP-SMA) so that my EEE PC has an external
antenna (an easy hack, but one I haven't seen any documentation
online for).
In the meantime, here's an old video I made a while ago playing
with non-Newtonian fluids. This is really easy to make (just
saturate water with corn starch) and very fun! Non-Newtonian
fluids are fluids whose viscosity is dependant on the applied
strain. So, the strain from the speaker constantly hitting the
fluid causes it to become much more viscous to the point of
appearing solid. This causes all sorts of fun! In this video I
played a 100hz sin wave through the speaker. I did this later
as a demonstration at the Dragon Academy and I have to say it
was a great success, I recommend it for any teachers or
demonstrators. Hope everyone enjoys!
