    Cover Crop Roller

    Cover Crop Roller

    This tool is used to roll standing annual cover crops and crimp the stem to prevent regrowth and create a heavy mulch in place that can be planted through using no-till drills, planters and transplanters. This tool entry is based on the Rodale Institute's open source design, and updated by ADABIO

    Micro Hydro Basics and Case Study

    Small scale hydropower is an inexpensive and relatively simple way to produce reliable energy. Here are some resources and case studies as an introduction to DIY hydro.

    Dripwall Delta

    Dripwall Delta

    The Dripwall delta collects solar heat in a drip of water and transfers that heat under the soil to keep roots warmer. It is a season extender that lets you start seedlings a lot earlier and also the heat stored under the soil protects seedlings from night frost.

    Roll Top Greenhouse Bench

    Roll Top Greenhouse Bench

    In the winter and early spring, seedlings in the greenhouse need extra protection from frost. Bench heating systems can provide the necessary bottom heat but without covering the bench, much of the heat is lost. Farmers typically cover their benches with agricultural fabric, plastic, or both but putting this plastic on and taking it off daily is cumbersome and takes time. This roll top system enables one person to quickly cover or uncover the heated bench.

    Mobile solar powered electric fence

    Mobile solar powered electric fence

    I'm interested in others ideas and knowledge related to creating a mobile solar powered electric fence. This sketch represents my concept and the products available online costing less than $100. My goal is to allow two pigs the ability to graze small parcels of land similar to a chicken tractor.

    ultra simple dry grain/pellet feeder (food, wood and other pellets)

    ultra simple dry grain/pellet feeder (food, wood and other pellets)

    about a year ago I started to investigate automatic fish feeders for my aquaponics pilot plant. None of them suited me: too complicated, therefore too expensive: wormwheels, automatic belts, lots of wiring, etc... The simplest way to move dry goods over a horizontal or slightly downwards inclined short traject is by vibration. So yes, I used a (battery operated) sex toy for my experiments, and it works an absolute marvel. There are plenty cheap vibrator motors availanbe, so the mechanical part of the problem is solved. But I will have about 10 fish tanks or more in my project, and fish are best fed at night, and the feeding is best spread over time so as not to overcharge the biologic filtration system. Wireless automatisation is the step in which this community can help. While I am familiar with programming PLC's, I find solutions like the Arduino not accessible enough to the general public. I have seen simple wireless systems to program i.e. christmas lights around the house.

    Seed Germination/Early Growth Chamber

    Seed Germination/Early Growth Chamber

    A seed germination chamber using a broken upright freezer. I got the idea from DGrover's "Sweat box" Germination Chamber: http://farmhack.net/tools/sweat-box-germination-chamber. I added onto his design by adding lighting, air circulation, a heat source and temperature/humidity gauges. This is a functioning concept that is being tested right now, and there are still issues to work out. Such as preventing excessive temperature and humidity levels as well as other concerns. So far the expense is about $150 (not including cost of freezer), nominal compared with a manufactured growth chamber, thus enabling small farmers/gardeners the ability to reliably start quantities of seeds early and extend their season.
