Aquaponic: Survived The Typhoon Haikui

August 12th, 2012 § 2 comments § permalink

The system is still showing some sign of the young aquaponic system, a bit iron deficiency. Chelated iron has been added to improve that as well as a bag of coral skeleton is added as PH buffer. Image]]>

Fix the aquarium air stone strip to the bottom of the drainage screen. Thanks to Rocket’s suggestion with his background in water processing, the air stone is mounted upside down. This is really clever one. It avoids deposit on top of the stone to make the strips last longer. Cool idea! IMG 3220 A small piece of PVC pipe with holes is used to tell water level and fixed on to the screen with cable tie. IMG 3219 PVC pipe is used to protect the air pipe from be squeezed by the ceramic ball. IMG 3221 All done and ready to fill in the ceramic balls. IMG 3223 Big ones at the bottom with 2 cm deep of small one covering the top. While filling in the nutrient solution, make sure only up to the big ones’ height and keep the small one dry. The small one is mainly used to insulate the lights and heat of the Sun from reaching the solution to prevent algae growth and heating up the solution. IMG 3224 Transplanted some cucumbers, sun flowers, and other seedlings started in the past few weeks. IMG 3227 Some words of advice, soak the ceramic ball in the water a few days before setting up the system so they will sink into the water. At the last picture, the big ball float to the top while I was planting the seedling.]]>

This month we’ve packed it full of some interesting workshops, from the latest “Ultimate Arduino Workshop”, to Analog line followers to RoboRacing! Keep an eye out for a Max/MSP workshop this month also, more information at the end of this email. Presentations * Jonas – look ma’ no loops! (cancelled) * Serena Pollastri/Francesca – TianTian * Sijie – Build your own multitouch table for your living room (cancelled) Wednesday Presenters * Jonas Karlsson (☯大鱼) will be talking about his new language “Look ma’ no loops!” he’s hacking a new language where you don’t specify what the computer should do and how instead, describing what it is you want. along with Some examples. * Serena Pollastri/Francesca – were commissioned by Nokia to study how rural areas of china use their mobile phones – they came up with an online marketplace for urban communities to trade directly with rural areas such as farms, tracking from farm to dinner plate. * Sijie (@Sijie_Amoy) is a designer and programmer. With a BA in Computer Automation and a Masters in HCI, he unlocks the future in his projects. He currently works at Google as a User Experience Designer since 2011.
