Esynch

A device placed inside each cow that injects prefilled hormones on schedule, automating a hormone protocol across a whole herd at once, for a Cornell research lab.

LOG · WHAT IT IS AND WHAT IT DOES

Esynch automates a hormone protocol for dairy cows: a device placed inside each cow carries prefilled hormone reservoirs and injects them on its own, and a web app schedules a protocol to be dispensed to all the cows at the same time.

WHY

This project was fully assigned to me as my first independent, full-scope development at work.

WHAT I WORKED ON

I started with documentation and research, then developed everything together: the electronics, mechanical body, firmware, PCB, hormone reservoirs and web app, and we did some testing. Once my development was done, other people joined to work on later iterations; on the latest one, I've mostly worked on refining the electronics and software.

WHAT CAME OF IT

We've done 3 rounds of in-cow testing with my versions, and the latest iteration will be tested in November.
