Instrument Rotator:
- Will eventually be installed semi-permanently on the main axis attachment plate.

- Motor controller is BSC201 from Thor Labs. HEAVY. Current plan is to remove back GAM controller plate and attach the BSC201 to the plate with metal strapping before re-attaching the GAM control back plate. This keeps things tidy.
- Also note: need to do a power audit if we want to plug a lot of stuff into the scope power supply.
Onkar and Eric will performe functions test of scope on Thursday at 10:00AM
