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.
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.
The tool shown here is a row/bed marker that is rolled out before direct seeding or transplanting. It's purpose is to quickly mark out beds at 1' intervals with an in-row spacing of 11" so that when I direct seed and transplant, crops will be planted on a grid for easy cultivation, harvesting and will facilitate in keeping track of yields / plants per bed.
Use salvaged windows and materials to construct a mini-greenhouse for season extension. These cold frames can be used to warm soil before planting directly in the ground, create a micro climate for seedlings and starts, overwinter dormant plants, and more.
Compost Sensor is an open source sensor system for monitoring and recording the temperature and moisture of active compost. It is for small scale commercial composting operations to help with quality control and the certification processes.
Custom versions of seeder rollers for a Jang seeder. So far, the YX-24 and LJ-24 are adapted to become YX-48 and LJ-48 rollers to double the amount of seeds that are planted per revolution of the seeder wheel. Instead of alternating seeds one at a time on each side of the wheel, our wheel drops two seeds at a time. We also made the holes slightly deeper on the LJ-48.
