Design Sleep Scheduler & Battery Switcher

[TylerFlar]

Objective

Design a circuit to manage power for the UP 7000 using multiple batteries, ensuring safe operation and stable power. The design must protect against reverse current between batteries and, optionally, monitor battery voltage to maintain safe levels.

Requirements

1. Sleep Timer
   • If the UP 7000 cannot manage its sleep mode, a microcontroller MUST be included so that the UP 7000 can turn itself off and on at an interval.
2. Battery Management
   • The circuit MUST use diodes to prevent reverse current on the same rail.
   • The circuit MUST cut power from the UP 7000 if batteries drop below safe voltage.
   • The system SHOULD support human hot-swapping of batteries without disrupting power.
   • The system MAY monitor battery voltage to alert if levels are about to drop below a safe threshold.

Tasks

1. Choose a microcontroller or set of controllers (if needed) that can handle power control and battery monitoring.
2. Design circuits for power control, battery voltage monitoring, and switching.

Deliverables

• Circuit schematic for power control and battery switching.
• Microcontroller code for managing sleep intervals, voltage monitoring, and switching.
• Test report validating system performance.

@TylerFlar

• Check if UP 7000 can turn self on and off
• Plug batteries into common rail and add diodes for battery safety.
