... а корпус со слепка страйковского в мастике отолью.

In the schematic this is shown as a circuit on the left, with the 3 steps on the right. Pin number 9 has PWM and controls the carrier wave and pulses, the rest is set open or close in steps..

How you could use this:
1: you pull the trigger
2: the LED shoots in the third configuration: 3.3 ohm + 100 ohms = 103.3 ohm -> short range, with HIGH damage
3: the LED shoots in the second configuration: 3.3 ohm + 1 / (100 + 47) ohms = 40 ohm -> medium range, with MEDIUM damage
4: the LED shoots in the first configuration: 3.3 ohm => long range, with LOW damage

If I am correct you would shoot 3 packages, each with a different range (because of the dynamic changing resistors) and a varying damage. Effectively, someone who is close to you receives only the HIGH damage package (he/she is close) and gets more damage. someone who is further away does not get hit with the low-powered shots, but the high power shot does some damage....

This would emulate real world, where bullets from close range have more damage than long range... right?

Идея Джима состоит в том, что бы выпустить по очереди пакеты в одном выстреле, в итоге, если попал первый идёт задержка поражаемости и второй не засчитывается.

Пакеты той же длины, просто их два (в приведённой цитате 3)
