Last night (Monday) around 8:00 I competed a viable finished product. I was finally able to get the gears from the mail room Monday morning and then began working on a gear box. The gearbox is shown up close below. I used nails and paperclips to hold them in place and the nails fit thru the holes very nicely. I decided it was not the best idea to have a realistic looking gun mounted on the car that actually shot bbs so I made this cardboard gun instead. The real reason is the motor was having trouble aiming it up and down with weight of the gun on it. I could have set up a counterweight system but I thought this was better for the above reason anyway. I made a solidworks design but I am clearly a tinkerer at heart because I abandoned the design and created a cardboard version from scratch. I ended up changing the rotating mechanism from gear based to a rotating wheel driving against a circle. Upon testing the final product works pretty well, both rotating and aiming up and down on a 27 Hz channel, as well as the car simultaneously driving on a 49 Hz channel. I am getting more parts from amazon wendsday and may or may not begin a whole new design. This one also doesn't incorporate the arduino in any way so I can add that even if i don't start the new project. I could incorporate the arduino by putting the 3rd remote channel I added into an input pin and making it light up lights in a pattern as a replacement for a firing mechanism on the air-soft gun.
