Things are getting exciting now in the Arduino Nerf sentry gun build! I’ve connected the main components together now — primary Arduino, secondary Arduino, motor, and power for the gun (I decided to removed the six D cell batteries and power it from an AC-DC transformer).
Here’s the Molex connector I soldered in place of the battery pack.
The primary Arduino is mounted to the stand, with 7-Segment shield display visible.
I cut a window into an aluminum chassis, and mounted the ultrasonic PING))) sensor inside. I attached it to the Nerf gun using a super-strong 3M version of Velcro.
The connector jack I mounted in the grip for the trigger wire was flopping around too much, so I secured it with a little bit of Sugru silicon molding clay. It’s excellent for this kind of fix. However, I found my hands were slippery like Teflon afterward, right when I had to screw in a zillion little screws.
I took these photos a few days ago, now I’m (not so) patiently waiting at Maker Faire for my boxes to arrive so I can set it all up to show in the Maker Shed and on the Make: Projects Stage.

wow!!!Good work.I din’t expected it to be so cool.
I think you deserve a BRAVO.
Well done, John!
Now, you just need to get someone to paint the gun, so it doesn’t look so silly.
