Notes

Updates from the past (2) weeks

@Yevgeniy Gorbachev (RIT Student) 

  • Ground Station CAD nearly done

  • Payload chute bay lid nearly done, @Grace Dertinger (RIT Alumni) manufacturing

  • payload internals printed by Matt

    • need the VTX/DARWIN sled printed again because DARWIN hole spacing changed

  • avionics bay manufacturing started

    • laser cutter rotary axis was off, fixed now

    • sent prints to Matt

Updates from the past (2) weeks

@Will Merges (RIT Student) 

  • ran IEPE test on DAQ with waveform generator

    • results look good

    • fixed firmware bug, ENA register was not being written to correctly

    • IEPE and CL interfaces tested now, can't generate small enough signal (~5mV) to test fullbridges

    • tried to test fullbridge interface with load cell, saw a lot of noise (verified by o-scope), think the cabling was poor

  • did not hear back from Jeff about DARWIN lab access

    • @Ben Hyman (RIT Student) followed up again with no response

  • putting together final BOMs of parts we still need

Updates from the past (2) weeks
