Nerf Dart Counter Heads Up Display

A custom dart counter display for ( but not limited to ) the Kriss Vector by Gears. It was built for the Vector but can be used with other nerf guns, as long as it has a pusher switch. This device uses the signal of the closing pusher switch to detect a dart passing through, instead of more complex and finnicky sensors. It also has a built in laser for those doing more plinking than player vs player.

Print Settings;

25% infill PLA, at .15-.16mm layer height. 4 Perimeters is sufficient for sturdiness. 

Hardware and Electronics;

• 1x Arduino Nano
• 10x M2x4 socket cap screws ( Securing front and backplate )
• 4x M2x6 socket cap screws ( securing OLED )
• 8x M2 heat set inserts
• 1x Epoch 18650 Rechargeable Battery
• 1x 0.95'' 7 pin color OLED Display
• 1x 5V Laser Module Board for Arduino
• 1x Buck Boost Module to 5V to power Arduino
• 1x buck module to lower the gate voltage of the pusher switch to 5v so the arduino doesn't blow up its digital pins.
• 1x 11.5mm diameter push latching switch

Assembly is simple; Just insert the heat set inserts into the main body at 230C works well. The arduino nano, latching switch and 18650 battery all are inserted into the main insert. The display mounts with 2x M2x6 screws going through the underside, with the sharp edge of the mount facing up. The mount itself mounts to the main body with another 2x M2x6's. The main insert, and back-plate mount with M2x4mm screws. The buck converter just sticks onto the empty space on the main insert. The laser uses 2x m2x4 screws to mount to the main insert. 

As far as programming the arduino, i will be uploading the code shortly. 

I'd love to see makes, and remixes ! Please ask questions as it is still a work in progress.
