Apr 28, 2023

Tests

Battery drain BRB (Result: 18h)
Battery drain RRC3 (Result: 15h)
Foxhunting BRB

Wiring

2x JST to BRB adapters

Bay Design

Fixes

@Donovan Barros (RIT Student) Shrink central connecting bar to accommodate backplane modules
@Donovan Barros (RIT Student) Add DE-9 holes for both downward-facing connectors
@Donovan Barros (RIT Student) Expand DE-9 holes to accommodate square-ish connector
@Donovan Barros (RIT Student) Check DE-9 connector dimensions to make sure they fit in the holes
@Donovan Barros (RIT Student) Update cut radii
@Donovan Barros (RIT Student) Change the dimensions of the BRB's battery inside the BRB model to match the larger battery
@Donovan Barros (RIT Student) Use shorter version of last year's battery holders (look cleaner)
@Yevgeniy Gorbachev (RIT Student) Saner battery layout
@Donovan Barros (RIT Student) Move RRC3s closer
@Donovan Barros (RIT Student) Resolve switch bar interference - move sleds around if necessary
@Donovan Barros (RIT Student) Move backplane up so the PEM nut doesn't stick out of the bay
@Donovan Barros (RIT Student) Correct sled height/width if slots moved
@Donovan Barros (RIT Student) Adjust slot corner radius to match tool (or we could just file it?)
@Donovan Barros (RIT Student) Add 1/8" charge lines to bulkhead CAD
@Donovan Barros (RIT Student) Add appropriately sized keep-out blocks to Fingertech screw switches
@Donovan Barros (RIT Student) Copy the RRC3 into the IREC 2023 Fusion project so we modify our copy instead of the library copy
@Donovan Barros (RIT Student) Add appropriately sized keep-out blocks to RRC3 terminal blocks
@Donovan Barros (RIT Student) Add appropriately sized keep-out blocks to D-sub breakouts
@Donovan Barros (RIT Student) Correct DE-9 breakout model
@Donovan Barros (RIT Student) Correct strain relief spacing
@Donovan Barros (RIT Student) Correct sled holes

Major additions/changes

@Donovan Barros (RIT Student) Design Finger Tech screw switch bracket (these are in)

@Yevgeniy Gorbachev (RIT Student) CAD battery and a holder
@Yevgeniy Gorbachev (RIT Student) Adjust COTS sled layout
Join BRB to antenna directly
Add new battery (should end up close to the upper end cap)
Add hole in upper end cap for new battery connector
@Donovan Barros (RIT Student) Hole drilling jig
@Donovan Barros (RIT Student) Integration plan
@Yevgeniy Gorbachev (RIT Student) Figure out which battery for backplane
@Yevgeniy Gorbachev (RIT Student) Lay out radio module antennas
@Yevgeniy Gorbachev (RIT Student) Update PCBs from Altium
@Donovan Barros (RIT Student) Design updated long key
