Arbor Day is a holiday many countries dedicate to planting trees, but with the steady encroachment of climate change, we need to maximize our time. Dronecoria doesn’t just plant a tree; it sows “hectares in minutes.” A hectare is 10,000 square meters or 2.471 acres. These aren’t the drones you’re looking for if you intend a weekend of gardening, this is in the scope of repopulating a forest with trees or reinvigorating a park with wildflowers. The seed balls in the hopper are 10kg of native seeds coupled with beneficial microorganisms to help the chances of each drop.
The drone’s body is laser cut from what looks like baltic birch plywood. The vector files are available in Illustrator (.ai) and CAD (.dxf) formats released under Creative Commons BY-SA, so give credit if you redistribute or remix it. In the 3D realm, you’ll need a SeedShutter and SeedDisperser, and both models are available in STL format.
We have other non-traditional seed spreading methods like canons, but it is a big job, and if you’ve build something to pitch in, drop us a tip!
Taking a stroll through the woods in the midst of autumn is a stunning visual experience. It does, however, require one to live nearby a forest. If you are one of those who does not, [Koen Hufkens] has recently launched the Virtual Forest project — a VR experience that takes you though a day in a deciduous forest.
First off, you don’t need a VR apparatus to view the scenery. Web-browsers and most smart phones are capable of displaying the 360 degree images. The Raspberry Pi 2-controlled Ricoh Theta S camera is enclosed in a glass lamp cover and — with the help of some PVC pipe — mounted on a standard fence post. Power is delivered ingeniously via a Cat5e cable, and a surge protector has also been included in case of lightning strikes. Depending on when you view the website, you could be confronted with a black screen, or a kaleidoscope of color.

[bugloaf] tipped us off about this flower power hack. University of Washington researchers, [Babak], [Brian], and [Carlton] have developed very low power circuits to run directly off of trees. This builds upon the work of MIT researchers and Voltree Power. A voltage of up to around 200mV is generated between an electrode in a tree and an electrode in the ground. Identical metals can be used as electrodes as the process is not like that of a lemon or potato battery. The significant development here is the use of a boost converter and exceptionally low power circuits. What kind of applications can you come up with for this source of power? Maybe you could try to combine this power with the power from donuts and hair.
