Ideally this person would be in the Northern California area.
I've got a customer with extensive experience in food production (baking, specifically). He's looking to modify a machine for liquid dispensing, making an aftermarket add-on to adapt it to a specific purpose.
The work consists of building the machine, designing some mechanical add-ons for it, retrofitting the machine with them, and creating some electronic controls for the system (using the Propeller, what else?).
The person you would contact is Bruce Parks firstname.lastname@example.org. This particular effort does not have anything to do with the Drone Pilots Federation.
