+# Portland State University Capstone
+PSAS flight controller
+
+written in Rust!
+
+# What is a capstone?
+
+# A capstone is...
+
+# ... a group project
+
+# ... with a sponsor from outside the class
+
+# ... who wants something awesome made
+
+# Who are PSAS?
+http://psas.pdx.edu/
+
+# PSAS is ...
+
+# ... a team of students that make rockets
+
+# ... for very low cost
+
+# ... and has open source software
+
+# ... as well as open source hardware
+
+# ... that want to put a satellite into orbit
+
+# PSAS has a challenge
+
+# Fly in space!
+(This means no wings or fins)
+
+# This is a big project
+So they decided on a new flight controller
+
+# New flight controller needs...
+
+# ... to use cold gas jets
+
+# ... to be testable
+
+# ... to be fast
+
+# ... to be safe
+
+# Decision
+Test using using JSBSim
+
+Fast and Safe: Rust!
+
+Read and write pins: i2c and gpio
+
+# These tools are complicated
+And we were not experienced
+
+So we did lots of research
+
+# We built a MVP with
+2 compile modes (flight and test)
+
+integration with i2c and gpio
+
+integration with JSBSim
+
+# To test it
+Flight: LED prototype
+
+Test: Read JSBSim output
+
+# Code breakdown
+  common
+    control.rs
+    data_fmt.rs
+    main.rs
+    sensor.rs
+  flight_mode
+    src
+    gpio.rs
+    i2c.rs
+    lib.rs
+  test_mode
+    src
+    gpio.rs
+    i2c.rs
+    lib.rs
+
+# Interesting statistics
+
+# 651 lines of Rust code
+does not include whitespace or comments
+
+overall over 1k lines
+
+# 43 lines of CPP
+For JSBSim integration
+
+(my slide software did not like the plus sign)
+
+# 668 Lines of markdown documentation
+Documents that Capstone class required
+
+# Interesting problems!
+
+# JSBSim is hard...
+and undocumented
+
+and kind of has spaghetti code
+
+and written in CPP
+
+# Different compile modes
+what do?
+
+different ways to solve this
+
+our way works, but is it the best?
+
+# Interesting Bugs!
+Counter-Clockwise bias (first video in playlist) (second video has bug fixed)
+
+Dual spin bug (third video in playlist)
