156B Week 9

Project Status

Electrical Wiring

Electrical wires were reconfigured to be as flat as possible. Issues regarding power distribution came to light and is being debugged. System should still work because we got it to run prior. Currently rewiring to make the system run again.

3D printed Housing

Current 3D printed housing was slightly off in dimension for one of the breadboards. A new case is being printed and should be ready by Thursday or Friday - Will finish complete assembly by the end of this weekend.
