![]() This way, we can just raise it up to work on the garden then drop it back down in place when we're done. We used 1 meter lengths of PVC piping to weigh down the net rather than tie it down. Next we covered the barrels with bird netting supported by PVC pipes joined together by custom 3D printed joints. Four barrels were cut in half and filled with soil, the fifth barrel is being kept as a reservoir for irrigation. The rooftop garden was converted from concrete raised beds to 200L HDPE barrels. The system works and gives us a starting point for scaling it up for the rooftop garden. It works by opening and closing a small valve using a 3D printed actuator, triggered by a hobby moisture sensor controlled by an Arduino. ![]() ĭecem| ProgressTH We've been busy with the rooftop garden, and in the process we participated in a 2-day workshop ( FarmHack 1.0) in which we developed a simple automatic irrigation system.Smart Ag Update: December 2016 ProgressTH.(1) 3D printed joint set (Thingiverse, coming soon).(1) NodeMCU + light sensor + DHT11 temperature/humidity sensor + breadboard/jumpers + 5V adapter (Home of Maker, Fortune IT Mall).(1) 80x80mm 12V fan + 12V DC adapter (Amorn, Fortune IT Mall).(2) 50mm x 25 m aluminum tape (HomePro).(1) 30w LED floodlight (Amorn, Fortune IT Mall). ![]() Hot glue is used to join everything together. This project is an attempt to replicate MIT's Personal Food Computer using materials readily available here in Bangkok at hardware, electronics, and stationary stores.Ĭareful, patient use of a utility knife can be used to cut the MDF board. Development is underway for a hydroponics or aquaponics system. So far, only two types of basil are growing inside it using soil as a grow medium just to see if anything at all will grow inside. The graphs here display the information as it is updated in real time using ThingSpeak. Using an IoT weather station from a previous project, we are able to monitor and record the internal conditions of the box. It has been used to successfully grow herbs before, but it is still unknown whether or not it can successfully be used with fruiting plants like chili peppers or tomatoes. It uses a 30W LED floodlight for illumination. This prototype was constructed from 600x400mm MDF boards, 3D printed joints, aluminum foil tape, and magnets to create a front magnetic panel for accessing the interior. The box also serves as a platform to add in automation for irrigation, ventilation, monitoring, and more. ![]() The box itself provides a means of suspending the lighting and enclosing it to maximize reflection back onto the plants. It is useful if you lack rooftop, balcony, or other outdoor space for growing. J| ProgressTH A grow box is a basic means of creating an indoor garden using artificial lighting and a varying degree of automation. The process is explained in more detail here.įollow on Facebook here or on Twitter here. In order to friction weld them together, a length of filament must be inserted into the gap and then welded over. Significant warping occurs when printing the side halves of the case. For an overview of this process, please see this post (with video) from Hackaday. Since this is a larger project, the casing and platform are pretty big and need to be printed out in pieces and friction welded together. Something similar is also possible for small rectangular tanks. It's probably unlikely you will find the exact glass container we are using, so the SketchUp file will help you see how we designed our project and give you a starting point for customizing your own system.Įven between the two containers we used, despite being almost identical, the diameter had to be adjusted by between 2-5mm. The files for this project, including the SketchUp file, are already up on Thingiverse here. The containers host platy fish, freshwater shrimp, and common aquarium snails, all of which have been successfully reproducing, creating a sustainable micro-ecosystem. All of this is placed within a modular metal shelf designed for supporting a lot of weight. Since there is not enough light indoors to grow anything of significance, a 30W LED floodlight is used above the first unit (left image, right side), and a 50W LED floodlight above the second (left image, left side). It is a small tabletop aquaponics system using a 350mm tall by 220mm diameter cylindrical glass container (14.5 liters/3.8 gallons), a modified 6 liter water bottle planter with pumice (volcanic stones), a small aquarium pump, and a 3D printed support and cover. J| ProgressTH This is the latest indoor system we are working on.
