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.
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.
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.
Mobile Wash Station
Low-cost DIY, mobile wash station for increasing efficiency in post-harvest processing. Needs exterior hose or spigot to use. The partnership was Elise McMahon, Liam Turkle, Fay Strongin and Tess Brown-Lavoie (both from Sidewalk Ends Farm in Providence, RI). We started working on it at FarmHack RISD and then finished it on 12 May in Providence.

small scale egg washing
A summary of exisiting egg washing technologies and some discussion of merits/goals of small scale egg washing, hopefully some designs and prototypes to follow...
Sub-irrigated raised planter
This concept is meant to provide consistent soil moisture levels to gardens with spotty or insufficient access to water. It take the idea of a sub-irrigated planter and applies it to an entire raised bed.

Drought Resiliance on the Small-Scale Farm
Initiated by the Farm Hack West Slope Colorado event, this tool navigates water supply and drought management challenges for small-scale farms in the Western US. The aim of this tool is to foster horizontal exchange of on-farm drought resiliency technique and innovation while preparing for changes in water scarcity and water politics in the West.
