Finished BOM for PCBs. Got prices for all components and checked with paul about what kind of capacitor the big one was. It was Panasonic 250V 10uF polyester film capacitor. He said that we could use a Tantilum capacitor instead, it would be smaller and cheaper. He specked one out; part # 478-1841-ND.
Checked what the longest pipe length would be that would yield a natural frequency of >10Hz, when a 2lb mass is located at the middle.
For pinned pinned BC, the longest could be 125".
For clamped clamped BC, the longest could be ~186".
Talked over tube length issues with Bryce. Concluded that we should just order the 2" OD tube. I ordered it from Tube Service. They only have 12' sections rather than 20' sections which could be a problem. They do have 6063-T6 in 20' sections but 6063 has lower ultimate shear stress.
Assigned part numbers to all the parts/drawings I created for the Fast GVT.
