== Project documentation ==
  
1. Purchase Arduino (the Uno is probably fine) and perhaps needed attachments (stepper motor driver?) - '''Done'''

The project documentation is available on the [http://www.opennautics.com/wiki/index.php?title=Main_Page Opennautics wiki].
 
+
2. Purchase appropriate valve, will be used in combination with a pneumatic jack
+
 
+
3. Purchase igniter (Spark Gap Igniter?) - '''Done'''
+
 
+
4. Write sketch to control valve and igniter - '''Done'''
+
 
+
5. Set up the rest of the plumping and see what tanks we have access to.
+
 
+
6. Create an injector plate to fit.
+
 
+
7. Determine pre/post combustion chamber insulation. Most probably some type of phenolic resin.
+
 
+
8. Turn nozzle from graphite based on chamber dimensions
+
 
+
9. Assembly and test
+
 
+
== Test stand ==
+
We plan to use the [https://opendesignengine.net/projects/shepard-ts Shepard Test Stand 2.0] design to set up our own test stand, scaled to withstand the thrust we plan to achieve.
+
 
+
== Testing checklist ==
+
This is the list of what we expect to measure out of our first motor tests:
+
 
+
1. Thrust over time
+
 
+
2. Temperature of combustion
+
 
+
3. Temperature of injector plate surface
