Inspired by the original NERF elite guns commercialy available, I made my own, compatible with the original (and chineese) NERF clips (or drum)
Currently writing the firmware for an ESP8266, but waiting for an i2C IO extender (ESP is short on IO) it can run on an Arduino but because of the PWM signals, the Ardiuno runs short on clock ticks (16Mhz)
