NEW! How To: V3.0 MAMA w/participatory instructions (beta) We are pleased to announce the V3.0 release of the windowfarms community’s latest windowfarm design, the V3.0, the Modular Airlift Multicolumn Array, or MAMA! quietereasier to set upmore elegant, but still do-able with all recycled water bottlesmore plants for less electrical input (up to 32 plants on one air pump if you do Rama’s double plant mod)modular, meaning you can supply proper nutrients to vegetative, fruiting, and flowering plants all in one system. No more airlift issues with the new tubes. And we have finally achieved some serious height!! Achieving height means you can grow more plants with the same pump so it is way more efficient in terms of the amount of nutritional calories per fossil fuel calorie used in powering the pump. This design described in the free how to is basically the same as the new Classic kit. We decided to release this as a participatory web guide that captures ideas, questions, sketches, discussion, & issues for R&D-I-Y while you build.

Next Generation LiveCode (Open Source) by RunRev Ltd We made it! A huge thank you to everyone who has supported the campaign so far. We still have some great rewards and great stretch goals. There is still a little time left to pledge. Great process for the platform today for students and educators. This is such an amazing new iOS app that we wanted to share details here. Have you ever had an idea for an app but don’t know how to code? Have you ever wanted to learn how to code but found it too difficult? Have you ever been frustrated by how long it takes to write an app? Are you frustrated with the current state of computer science education in high school? Do you want to help establish coding as a new form of literacy? Are you interested in a better way to write software for your company? If you answered YES to any of these questions, then we need your help. In 1987 Apple created a program called HyperCard. LiveCode is like a next generation version of HyperCard. There are some things it can’t do – yet. It will let you write programs in English.
Green Roof Growers: How to Make a Two Bucket Sub-Irrigated Planter (SIP) This is a simple, easy-to-do project that will let you grow your own food wherever there’s enough sunlight--on your roof, balcony, back steps, driveway, or vacant lot next door. It doesn't take any special skill and the materials are all readily available. A diagram showing what's going on inside a SIP is here. The fundamentals are the same whether you use buckets, tubs, or Earthboxes. Once you make one, it will produce beautiful food for years to come. Many of the photos here are from this second SIP run on the roof, and the pretty yellow pickle buckets are courtesy of Bruce's neighbor who drives for Chicago’s own Vienna Beef (Thanks, Rey! While these instructions are full of details, what you want (a healthy, productive plant) doesn't depend on following them exactly. If you've got hole saws it's far easier to cut the two big holes. View this quick video for a sense of how the whole thing comes together. So now you're ready to make one. This is the fun part. Look what you can grow
HEATWORKS MODEL 1: Your next water heater! by ISI Technology - CEO Jerry Callahan All existing electric water heaters rely on convective heating elements. Operational and safety issues with the heating element technology include premature failure of heating elements and flow switches, scalding issues related to thermal mass, unacceptable low-flow water temperature control, inability to turn on at flow rates less than 0.5 gallons per minute, (1.9 liters/min) and inability to operate in intermittent or aerated water flows. In short, antiquated, unreliable, and inefficient. In order to accurately purchase the correct unit for your home, you have to compare dozens of units. ...Than conventional electric tankless heaters. Electricity passes through a heating coil which is heated to over 1000°F (538 °C) which then heats the water. Not having a flow switch also saves water because the MODEL 1 produces hot water at 0.1 GPM (.4 Liter/min), while competitive units require at least 0.5 GPM (1.9 LPM) just to turn on. ...Than competitive units. www.myheatworks.com
Open Source, Ultra-Bright LED Lumapad with WiFi & Arduino by Richard Haberkern With the success of this project, the Lumapad will be one of the brightest LED lights made with all these incredible features. Thirty two (32) ultra bright LEDs are positioned in a landscape array to provide bright, even and controllable lighting on any subject. It is truly unbelievable how bright this thing is even though it draws only 88 watts. A built in electronic dimmer makes the light intensity adjustable to suit any environment. Great for studio and stage lighting, special effects, experimentation or anywhere an ultra-bright 8000 lumen lighting system is needed. Introducing the first Open Source, High Intensity, 8000 lumen LED Lighting System with embedded Electric IMP WiFi, Atmel AVR and Arduino built in. Be sure to visit Lumapad.com for more information. This is no ordinary bright light! *color adjustment available on dual channel Lumapad only Optional dual color temperature prototype shown in video Who says you have to be in the dark to go green? Simulated lightning.
How To, soil moisture, water valve, light sensor How To This section has various tutorials on the different components you might need to build a garden monitoring system. The entire how-to section is organized by modules -- each kind of sensor gets its own module. The overall concept is that you will generally have a microcontroller (like Arduino) hooked up to sensors (like soil moisture) and actuators (like a water valve). If we think of the whole system as a robot, then our microcontroller is our brain. Because of the long distances in volved in automation of even a small garden, some of the modules (like the soil moisture sensor) are bound to be physically far away from the brain. Throughout these tutorials I use the term local circuit. The Modules Running wires to remote modules To connect the various remote modules (like the control panel or the garden station) to the brain, you will need to run wires -- some very long wires. Probably the cheapest option is to purchase a roll of 6-strand phone wire (see the parts page).

This project will reclaim countless wasted kWh per year from appliances such as:- Dryers- Hot water heaters- Heating Units We hope you can see the benefit of this project towards a sustainable lifestyle, energy efficiency, and the energy economy. - High efficiency bar & plate heat exchanger technology borrowed from expensive race car intercooler designs for high flow rate, handles hundreds of degrees, and high pressure.- Easily cleaned stainless steel fine mesh lint filter in the inlet. - Standard 4" duct inlet and outlet manifolds.- High efficiency sensor driven electronic fan controller unit .- Demoed saving more than 2600 Watts! Appliance waste heat is an inefficient use of energy resources that could be improved with the use of simple robust technologies for energy reclamation.
For Journalism by Dave Stanton We're creating educational materials for the next generation of news-application developers. Python, Ruby, maps, devops and more. We have a pipeline problem for people with data and programming skills for journalism. There are great organizations and institutions making tremendous headway, but we need an industry-wide solution for educating the next generation of journalists. Today there are no course materials for learning skills for building modern news applications. We are creating resources to address this need by employing professional experts in specific skill areas, and we will structure our materials to have journalism contexts. For Journalism is an effort to equip every student, mid-career journalist, professor and graduate student with the knowledge they need to learn technical skills for doing journalism. Our initial plan is to offer these eight courses. an ebookscreencastscode repositoriesforums For Journalism is definitely for you.
Plantduino Greenhouse UPDATE 7/9/11: The AC power fed relay has been replaced with a DC battery fed relay system as shown in step 10. UPDATE: We have been selected as finalists in the microcontroller contest! Thank you for voting and rating. Thank you also for all the feedback on the safety of out relay system. Hello Everyone! My name is Clover and I am in love with vascular plants and robots. This summer I wanted to combine my two loves of plant science and engineering. I have constructed an automated watering and temperature system. This is my first project using an Arduino so I am using wonderful articles from MAKE and Instructables as very helpful templates.
