    Auto-fill High Output Temperature Controlled Humidifier

    Auto-fill High Output Temperature Controlled Humidifier

    This project turns a 5 gallon bucket into a high capacity (4 gal/day), automatic fill humidifier. The bucket serves as a reservoir for the water and also as a mounting platform for the parts required to operate the humidifier. Water heated to a know temperature will transfer a predictable amount of water vapor to an air stream of a known temperature and humidity (wet bulb temperature). We use this property to develop a highly controlled humidifier using a temperature control to sense water temperature and control the heater, tank deicer for heat, and a CPU fan for air flow. We also add a toilet fill valve to the assembly to allow for automatic fill of the humidifier. NOTE: Pictures shown from the first build do not include complete safety features including: electronics enclosure, GFCI protected circuit / outlet, and terminal covers. Please take care when wiring and using this design to ensure personnel and property protection.

    bicycle powered thresher,fan mill, and dehuller

    bicycle powered thresher,fan mill, and dehuller

    Links below to the complete plans for bike powered tools for small scale grain processing; a thresher, a fan mill/winnower, and a dehuller/flour mill. The plans guide a farmer or a fabricator through step-by-step instructions using wood, metal, and scavenged bicycle parts. The cost of materials is $200 per machine and the machines process about 1# per minute for each process. In a well equipped garage/shop the machines can be built in 20-40 hours each.

    Collecting sensor data in FarmOS using GrovePi and Node-RED

    Collecting sensor data in FarmOS using GrovePi and Node-RED

    A simple way to collect data from sensors, like temperature and humidity and store it in FarmOS.

    Heated Greenhouse Table

    Heated Greenhouse Table

    Heated greenhouse tables serve two main purpose on the small market garden veggie farm. First, it offers a place with a fairly constant temperature to ensure high germination rates. Not too unlike the Sweat Box Germination Chamber (http://farmhack.net/tools/sweat-box-germination-chamber), However, this tool allows us to continue growing the seedlings under optimal conditions until they get a bit stronger. Secondly, we can get some onion plants out to the greenhouse to free up room in our seedling room. We start onions and greenhouse tomatoes under lights in the basement, then move them out to the greenhouse when we are ready to start heating the greenhouse/nursery.

    Flow-Through Vermicomposter

    Flow-Through Vermicomposter

    The purpose of this tool is to provide a space to vermicompost a variety of waste ( animal manure, food scraps, or other organic waste) with worms and produce safe worm castings, a valuable resource. The worm castings can be utilized in a variety of ways on the farm or sold to other farms and gardeners.

    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

    Bicycle Powered Thresher

    Bicycle Powered Thresher

    Complete instructions for making a bicycle powered thresher. Thresher works on various crops including dry beans, wheat, rice, rye, einkorn, and lupine. Threshes about one pound per minute. This is the first of three tools for small scale grain processing designed to allow small farms to dabble in grain. The other two tools are the bicycle powered fanning mill and the bicycle powered de-huller/flour mill.

    Fido, the temperature alarm that sends text messages

    Fido, the temperature alarm that sends text messages

    Is your greenhouse getting frosty? How about too hot today? Is your fridge still on? Fido is a temperature alarm that will send you text messages that you can build for around $100. Solder together the Arduino based model or snap together the Raspberry Pi based model.

    Tough inexpensive pastured pig waterer

    Tough inexpensive pastured pig waterer

    Pigs are tough on equipment. This simple water system doesn't tip in a pasture situation, stays clean and prevents the pigs from disturbing the hose connection.

    Sweat Box Germination Chamber

    Sweat Box Germination Chamber

    A "sweat box" style germination chamber built using readily available parts and a broken chest freezer. Early season germination can be inconsistent without a closely controlled environment for starting seeds. Commercial greenhouses use similar systems but the cost can be prohibitive for the small vegetable grower.
