Introduction • Jetdrop 3000 • Altimeter for a rocket that delivers data down to the ground and drops an object in a parachute at a certain height. • Target audiance: Students at the Swedish technical school. • Problem: Rocket modelers can always use a cool addition to their rockets.

Background Figure 1: a drone [Dro16] • Drones • Keychain camera Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 4 / 14

Use case Figure 2: The Swedish flag [15] • Customer selects what item he wants to drop • Customer selects whether he wants to drop manually or automatically at a certain height Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 5 / 14

Customer Needs Figure 3: Our Swedish friends building the rocket at the [AA15] CN 0 To know the altitude of the rocket at any given time. CN 1 To drop a thing down from the rocket. CN 2 To get pictures or videos from the rocket. Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 6 / 14

Design: Modules • 2 modules: Flight computer and mission control • Altimeter ( DP 0 ) is on the flight computer • Hatch ( DP 1 ) is also on the flight computer • The item to be dropped (fx. a camera) is also on the flight computer • Hatch open command can be sent from mission control • Hatch can be automatically opened at a certain height Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 10 / 14

Design: Bill of materials (BOM) Bought and arrived • 2 x SparkFun [Spa16c] RedBoard = 12.000ISK • 1 x SparkFun [Spa16b] Altitude/pressure sensor = 2.242ISK • 2 x SparkFun [wixel] Wixel = 5.712ISK • 2 x Sparkfun [logiclevel] Logic Level Converter = 842ISK • 1 x 50W servo-motor = 1.000ISK • 1 x 9V Battery [Spa16a] = 800ISK Donated • GoPro [Fot16] GoPro camera = 39.990ISK Total: 22.596 ISK Budget: 25.000 ISK Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 11 / 14

Status Figure 4: Our system dropping a camera in a parachute. • Software is in pretty good state after Lab 3 and 4 • We need to build a hatch and test Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 12 / 14

Tasks remaining • Barely 4 weeks left • This week: Plan how to design the hatch • Next two weeks: Build the hatch • Final week: Test Guðný Árnadóttir, Harpa Þrastardóttir, Hildur Egilsdóttir & Þorbjörg Pétursdóttir (RU) Jetdrop 3000 October 18, 2016Rev 159 13 / 14
