Re-Farm the City is an open-source hardware initiative aimed at creating low-cost tools for urban farming. This two part workshop series will introduce you to the project. At the end you will have built the electronics for your own mobile urban farm. This includes soldering all the boards needed to control and monitor an urban farm and testing different watering systems. (There will be a $50 lab fee to cover cost of materials.)
Workshop is facilitated by Jon Santiago. It runs from noon to 4PM on both Saturday and Sunday.
