32#### "RocketNet" Data and Power Distribution Board (ECE Capstone course)
33
34 - STM32-controlled power switches
35 - 8 port 100Mbps Ethernet switch
36 - Umbilical interface and battery charger
3732
38#### Olimex STM32-E407 based IMU with Ethernet33#### Olimex STM32-E407 based IMU with Ethernet
3934
35We have an [[Analog Devices ADIS 6 axis + magnetometer IMU|avionics/av3-imu]] that needs integration into our flight computer. We have opted to use an STM32 ARM based microcontroller to handle low level communication with the sensor, while reporting it's values over Ethernet to the FC.
36
37
40#### Olimex STM32-E407 based roll control with Ethernet38#### Olimex STM32-E407 based roll control with Ethernet
4139
40We want to use the same STM32 architecture to do other low level work, in this case send updates to the roll control servo. This board does also doubles as the hardware launch detect (using a shorted tether).
41
42
42#### LTC API43#### LTC API
4344
44 - And Ground software45Over the last year we rebuilt our [[Launch Tower Computer (LTC)|GroundTeamHome/launch_tower_v3/]]. This computer serves as the link to the rocket when it's on the pad, providing power and communication as well as safely controlling the ignition. This also meant rebuilding the software to talk to it.
45 - No gel cel for ignition (liPo instead)46
47
48#### Roll Control on the main Flight Computer
49
50We validated Roll Control on our October 2010 launch. But this was using a one-off, completely embedded solution. We very much would like to fly the same algorithm using our new flight computer framework, Ethernet communication, etc.
4651
47#### Roll Control on FC
4852
49#### FC Rocket Ready based on real contstraints53#### Flight Computer Framework
5054
51 - 55This winter/spring CS Capstone team built a [Flight Computer Framework](https://github.com/psas/elderberry). This allows us to write modules in c and then define the connections and program flow between them using simple configuration files. The framework then handles setting up the build targets, events and callbacks for the computer. This is the flight test using the new code.
5256
53#### RocketTracks
5457
55 - Stretch goal?58#### FC Rocket Ready based on real constraints
5659
57#### Update Camera60The new LTC has an additional level of safety on the firing sequence. The flight computer _must_ assert a line high to let a relay close and allow the rocket to be fired. This lets us check for conditions on the rocket (GPS lock, sane sensors, etc.) and automatically safe the launch circuitry if something goes wrong.
5861
59#### 3D Printed Connectors62#### Updated Camera
6063
64We have a new HD camera pointed out the side of the rocket, as well as a new 3D printed shroud for the downward facing camera.
6165
62### Technical Nitpicks
6366
64 - More thoroughly test GPS67#### 360 Camera Module
65 - Ground systems test (antennas, wifi)68
66 - Integration test69A special payload is flying on this launch. A 360&deg; camera module made up of 5 GoPro's will sit just above the roll control module and will be stitched after flight into a singular, extreme HD full view of the flight!
67 - FCF test70
71
72#### 3D Printed Net Connectors
73
74One of the small innovations on this launch are small, locking connectors for the ethernet and power that are partly COTS and partly 3D printed.
