Fresh hacks every day
Controlling the pH level of a solution is usually a tedious task. Adding an acid or base to the solution will change the pH, but manually monitoring the levels and adding the correct amount isn't fun. [Reza] rigged up an automated pH controller to keep a solution's pH steady. The build uses an Arduino with a LCD shield, screw terminal shields, and [Reza]'s own pH shield attached. A peristaltic … [Read more...]
This is some extreme gardening. [I Am Become Derpth] didn't let lack of space or tillable soil stop him from growing a bountiful harvest. Instead of cutting though prairie sod to begin the farming he had to contend with the concrete expanses found in the NYC area. Here he's nearing the end of an impressive aquaponics installation in Brooklyn, New York. For a good overview of what aquaponics is … [Read more...]
[Eric Maundu] is farming in Oakland. There are no open fields in this concrete jungle, and even if there were the soil in his part of town is contaminated and not a suitable place in which to grow food. But he's not using farming methods of old. In fact farmers of a century ago wouldn't recognize anything he's doing. His technique uses fish, circulated water, and gravel to grow vegetables in … [Read more...]
Add some fruit to your indoor bounty with this hydroponic strawberry farm. [Dino] whipped this up as his 45th hack a week episode (getting pretty close to his year-long goal). He used parts you probably already have sitting around the house somewhere. But even if you bought everything and used it once you still wouldn't be out much. A plastic storage container serves as the base. [Dino] also … [Read more...]
With fall approaching you might think about moving your gardening inside. [Jared] used cheap and readily available materials to make these salad-green trays. When used with his grow lights and tent (which he built during a different project) he was able go from seed to salad-bowl in just four weeks. A pair of plastic storage bins act as the base, keeping the water right where it should be. … [Read more...]
[GrowColt] shows you how to modify a lamp timer for use with hydroponics. You can pick up this type of mechanical timer at most local big box stores for around $5. The timer plugs into an outlet, and the device you want to operate plugs into it. [GrowColt's] end goal is to make the timer repeat every 35 minutes, routing power to the connected device for about 50 seconds each cycle. It will operate … [Read more...]
