ARDUINO-BASED CUTDOWN DEVICE FOR HIGH ALTITUDE BALLOON This project would involve designing, programming, and fabricating a finished prototype, possibly using a small single-purpose Arduino processor (i.e. Micro or Nano, or something similar) to serve as a cutdown device for a high altitude balloon. Requirements: - The device needs to be as small, lightweight, and durable as possible. - The device needs to operate using an Energizer Advanced Lithium 9-volt battery as its power source. Operation: Basically, the device would be a simple timer. - Turn on the device and a small red LED begins to flash, letting the user know that the device is active. - Turning on the device starts a 60-minute countdown. At the end of the 60-minute period, the device would activate a reed relay to allow current from the 9-volt battery to flow to a user-supplied piece of nichrome wire that would heat-up and sever a small piece of braided mason lin...
