DC Motor powered Lego style/compatible Auto launcher/shooter

Use DC motor powering the rack/gear pair.
This little thing could shoot ping pong ball/small things out.
This system is easy to make and sure to fire. A shooter with 2 high-speed brushless motors required much more than a simple reduced-gear DC motor.
NOTE:
1) shoot-pinion-27mm is much better gear which runs about 27mm
2) need to use M3 screw to secure bracket together. (12-15mm flat head screw)
3) use M3 screw to mount lego beam (12-15mm flat head screw)
