ROMAN
romanesco-broccoli-fractals-timelapse
This roman cauliflower was sowed in april and was growing in southern Finland on an open field for 3 months before it was taken into a green house where it was filmed growing on a 2 month period - the camera powered by solar panels. An extra light source would have been convenient to also get the night time footage for a more intact big picture. Although the project didn't go exactly as planned I thought this is still something worth sharing - Broccoli didn't produce one solid flower bud. There was another one (the last clip) that produced more solid one but it was getting too close to winter and growing season was already over. There was another 100 broccolis growing outside but all of them were eaten by pests.

HORIZ
horizontal-magnetic-levitation-homopolar
Horizontal diamagnetic levitation of magnetic arrays and levitating homopolar motor. Two supermagnete 400 kg fishing magnets as lifter magnets and a levitating 20mm x 10mm ring and 10mm x 10mm disk magnet combo. The motor was pretty much a failure. I tried it with 9V battery and with two 9V + 9V batteries without any better results.
Huge thank you for supermagnete for sending these for free:

32,4
32-4-lbs-flywheel-spins-5-hours-on-its
Check out my giant fidget spinner - a 32,4 lbs flywheel that spins 5 hours on its own momentum - barely suspended with neodymium magnets using two 1" ball bearings as contact points Two 100 kg pull force Neodymium magnets and two 80 g / 1 inch diameter steel ball bearings form a great suspended low friction bearing for the 14,7 kg flywheel. To get the lowest possible friction I adjusted the magnetic holding power so that it was just enough to carry the weight of the flywheel. Once I got the wheel spinning really fast and the spinning was steady enough I took the added metal off again for lower friction. With pneumatic air you could get even faster rpms. A thin layer of sewing machine oil for the contact points also helps to preserve the inertia. I Made top and bottom spoke covers out of plywood for better aerodynamics as AVAmagneticlev suggested. Magnetic pull force was adjusted with regular metal bolt and nuts to the absolute limit and added more metal for the launch so the wheel could withstand the trembling caused by the drill. More metal on the magnet makes the magnet stronger - which is a interesting phenomena in itself. The flywheel spun for over 5 hours and rock-backed additional 17 minutes.
