Outside Air Exchange Control
This tool demonstrates the use of two thermostats to provide a control system for an air exchange fan that draws cold outside air in to cool a storage room for winter crops. The control essentially provides a differential temperature control which may also be applicable to other processes (curing, solar hot water, etc.)
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.
Manual Seed Cleaning Box
This tool was built to solve a basic sifting/screening problem in a simple manual way, but with decent capacity. It is designed to use readily available parts and to be stackable if you want to screen in stages.
SwitchBox Control
Cell phone controlled switch for block heaters, fences or any electrical device!
Wheel hoe
Easy to build, inexpensive wheel hoe made from old bike parts.
simple butternut squash peeler
This spike chucks in a hand drill and spins a butternut squash, allowing you to peel it with a grater (i find a half round sure-form to be a greater grater). There is a video at: https://www.youtube.com/watch?v=r1u3sPFnBQw
ISOBlue
Free the data: an open source project to forward ISOBUS messages from tractors over Bluetooth.
Open Pipe Kit
The goal of Open Pipe Kit (OPK) is to be the missing plumbing between sensors and databases that will empower thousands of data journalists, civic hackers, farmers, etc. to collect data without needing a programmer's assistance or being locked into one data platform from a proprietary turn-key solution.
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.
FARM DATA
FARMDATA is an internet based smartphone compatible records management system for produce farmers. Focus areas include field and greenhouse plantings, harvest, pack, inventory, distribution, e-invoicing, labor tracking, fertilizers, compost, cover crops, tillage, irrigation, scouting, spraying, and seed orders. The goal of FARMDATA is to replace clipboards and paper records across the produce farm, from the field to the packing house and beyond. More importantly, FARMDATA is designed to save growers valuable time both during the busy growing season and in the winter when planning for the coming year. FARMDATA improves record keeping by using “smart” data entry forms that minimize user errors, perform calculations automatically, and store useful crop production information.
