Night Light - USB
thingiverse
A Red LED illuminates a telescope powered by a USB battery pack. Use whatever color LEDs you prefer, but design calculations are based on 2-volt LEDs. Power sources used include Jackery and Kamashi battery packs. The Kamashi automatically shuts off if the power draw is too low, so I added a single LED to keep it running. A toggle switch selects Single_LED, Off, or All_LEDs modes. A standard USB cable powers the device, and there's a holder for the Kamashi battery pack attached to it.
