3D model description

3D Printed Arduino Airgun NANO Chronograph with 4x20 LCD display and Microsoft Excel 365 Data Streaming real time shot by shot analysis.

Barrel mounted 4x20 LCD display shows pellet velocity in Feet per Second including average, deviation, minimum & maximum.

The display also shows power in Foot Pound including average, deviation, minimum & maximum.

The chronograph and airgun connections are all 3D printed.

The chronograph is powered by 4 AAA batteries or USB.

Connecting a USB cable to a PC (not available on Apple devices) with Office 365 running the enclosed spreadsheet allows detailed live shot by shot analysis of your Airgun performance.

Airgun Connection

3D printed barrel adaptors have been included for standard 1/2inch UNF (Unified National Thread) barrels and also a universal slip on moderator fitting adaptor.

I have set this for my Remington Airacobra moderator but it can be changed in seconds to suit your moderator.

There is also an adaptor for fitting over larger third party moderators.

Power

The chronograph can be powered from 4 AAA (LR03) batteries or USB.

The chronograph draws 68mA with the LCD backlight off and 83mA with the LCD backlight on.

Using alkaline batteries this will give approx 10.5 hours use with the LCD backlight on and 13 hours use with the LCD backlight off.

Note I have used a Yellow/Green LCD display as the screen is visible in daylight with the LCD backlight off.

The mini USB connector from the Arduino Nano is available through a cut in the main body.
