Top 8 Tips for Growing Organic Vegetables A lot of people, especially beginners, make quite a lot of mistakes in growing vegetables. Not even trying to be offensive here, they just do, and there are some rules you simply HAVE to follow in order to grow your veggies well. But fear not for I am here to spread knowledge and love! Being omniscient is a rather okay occupation. Android Repair Dear Massachusettsan, The people of Massachusetts have always stood up for their right to repair. In 2012, voters passed a law that ensured residents' right to repair their car wherever they wanted. Now, it's time to do the same for electronics. With the Digital Right to Repair Bill, H.3383, we have a chance to guarantee our right to repair electronics — like smartphones, computers, and even farm equipment.
Natural Pools or Swimming Ponds Natural Pools or Natural Swimming Ponds (NSPs) Let nature clean the water... Chemical-free water garden and swimming pool. The plant portion, or regeneration zone, is separated from the swimming area by the wall seen a few inches below the water’s surface. www.naturalswimmingpools.com The pools have skimmers and pumps that circulate the water through the regeneration zone and back into the swimming area.
InMoov » Nervo Board + Components The Nervo board was developed by Marten de Groot and Leon van der Horst. What is it? It is an Arduino-compatible shield for Uno or Mega that allows you to connect all the servos of one side of InMoov robot. If you are building the complete robot, you actually will need two of these sets. This board can also be used if you are only building the hand, or just the head.
Earth - Six bizarre things about fungi Fungi gave us alcohol It’s impossible to write an article praising fungi without first thanking Kingdom Fungi for getting early humans drunk. One group of fungi, the yeasts, generates their energy through a process called fermentation. Yeasts take sugar from plants, and break it down into a compound they can use for energy, along with the byproducts carbon dioxide and alcohol. Terra Preta Toilets Urine diversion terra preta toilets are dry terra preta sanitation (TPS) systems based on urine diversion, lacto-fermentation, the addition of charcoal and vermicomposting to produce lasting and highly fertile soils with properties similar to the terra preta soils (GENSCH 2010 b). Pre-Columbian native populations generated terra preta soils, literally “black earth”, by incorporating large amounts of charred residues (charcoal) either produced intentionally or as a by-product from human activity into the soil together with nutrient-rich material (GLASER 2006). Nutrient-rich material was used to be human and animal manure (rich in P and N), waste including mammal and fish bones (rich in P and Ca), ash residues of incomplete combustions (rich in Ca, Mg, K, P and charcoal) or plant biomass (e.g. kitchen wastes, compost, algae etc.) (GLASER 2006). A typical soil from the Amazonian region (left).
HNTE - LED Cube This is exactly what it sounds like, an awesome flashing cube of LED's. After seeing a 512 LED cube on hackaday I decided that I needed one for myself and went right to ebay to find some cheap LED's. Although 512 LED's seems like a daunting number it only took one weekend to make the control circuit and construct the cube, the code and animations though took a few weeks, maybe coding isn't my thing. I will go through some of the steps and theory here and you can see the results in the video at the end. The Finished Product
Millions of GMO insects could be released in Florida Keys © Derric Nimmo/Oxitec/AP Photo Undated handout image of a genetically modified Aedes aegypti mosquito in an Oxitec lab in Great Britain. KEY WEST, Fla. — Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases. Never before have insects with modified DNA come so close to being set loose in a residential U.S. neighborhood. Natural pools are beautiful and environmentally friendly A natural swimming pool is a magical addition to a home where you can observe nature throughout the seasons and be closer to the wildlife you share your land with. Some of the creatures you will attract are insects like water beetles and dragonflies; birds will visit the pond to bathe, feed and collect nesting material and amphibians like the frog and newt will take up residence. Your pond will become a stepping stone for the wilderness where local native flora and fauna will find your pool and flourish.
Infragram: the Infrared Photography Project by Public Lab Collections Sections Categories On Our Radar Start a projectStart Seed Balls Take The Hard Work Out Of Planting Gardening is a pleasure for many people, but others find it something of a chore. If you fall into the latter camp, try creating seed balls for easy growing with minimal ground preparation. By coating seeds in clay, soil and fertiliser, seeds can easily establish in areas that are considered difficult or impossible to prepare.
