####A (Red) light for telescope powered by a USB battery.
Use whatever color LED's you want. Design/calc's based on 2v LED's
Power source's I use are either Jackery or Kamashi.
The Kamashi turns itself off if power draw is too low, so there is a single LED to keep it on. Toggle switch selects: Single_LED, Off, All_LED's
The power cable is from a typical USB cable. There's a holder for the Kamashi battery
