Garduino Upgrade, Now with more Twitter! A couple months ago I came across two great instructables. The first was the Garduino, an arduino controlled garden to help you grow plants at home. The second was the Tweet-a-Watt, a project that teaches you how to monitor your home power usage using Xbees and Twitter. I read about both these projects here at Instructables and in Make Magazine, Vol 18. I thought it would be great to combine both these projects and build myself an indoor garden that I could monitor from work via Twitter. If you're ready then head to the next step and begin the process!
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. We hope the new instructions are clear. We will be continually updating as we make progress on the new design. 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.
Make Your Own Natural Bug Repellent Using Essential Oils « Hilltown Families Shoo Fly, Don’t Bother Me!By Tony(a) Lemos, HF Contributing Writer Click here to subscribe to the Hilltown Families weekly eNewsletter! Have it delivered to your email in box once a week for free! It is easy to make your own non-toxic bug spray by using store bought essential oils. Essential oils are steam-distilled pure concentrates of the natural oils present in plants, flowers, roots, and trees and can be purchased at your local health food store. The high amounts of essential oils that are so often found in store bought natural bug sprays are unnecessary, and can be made at home using less.To make your own insect repellent, combine rubbing alcohol, witch hazel, vodka, or olive oil with one of the essential oils listed below. Create your own natural bug repellent! If you find that you need to apply repellents several times throughout the day, and you are doing this everyday, I recommend that you make several different repellents and use them in alternation. Eat less sugar and more garlic!

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). 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). These long-distance connections would be a perfect place for wireless connections. Expanding your GardenBot GardenBot is designed to be extensible. Let's say you want to add another soil moisture sensor so you can compare the two.
Home Built Hydroponics Unit for an 8th Grade Science Classroom - The Hydroshack Lives Again! My wife teaches 8th grade science. This project "The Hydroshack" is a rendition of one I built over 20 years ago in my college teaching methods class. It is designed specifically for performing experiments in a science class. Please keep in mind that this instructable is not the only way to do this. Features:Uses NFT (Nutrient Film Technique) - Nutrient solution flows along the bottom of the troughs and washes over the plants roots.Very dense plant arrangement to accommodate 150 students in a 5' x 2' footprintCounter top unit that breaks down to be stored above the cupboards in the classroomEasy access to replenish and clean the nutrient tanks.Flexible controls to allow for differing conditions: nutrient flow, nutrient solutions, lighting etc... in each trough. Educational conditions:The Hydroshack will be used to teach the students the "Scientific Method" (formal experimental procedures) and also be used in the genetics portion of the class. Also, I had to redesign the control panel.
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. 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. While it's obviously sped up, it helps to see one done before you try it yourself. So now you're ready to make one. This is the fun part.
My Indoor DWC Hydroponics System To the naked or untrained eye, plants can appear as very simple and boring forms of life. In reality, plants are very complex creatures. In fact, genetically speaking plants are about twice as complex as humans. They exist in two very separate yet two very interconnected and equally important worlds. The shoot system of the plant is what we normally see when we look at a plant in the ground. This chemical process is known as photosynthesis in which the radiant energy from the sun is harnessed and converted into chemical energy in the form of sugars. The process of photosynthesis is actually much more complex than the above chemical reaction. The root system is responsible for providing the leaves and the rest of the plant with the required raw materials for metabolism and photosynthesis. There are three main problems with soil that limit the growth of a plant:One is that soil does not contain a whole lot of oxygen that the roots need to survive.
