PIC Paintball / Ballistic Chronograph

September 05, 2011 By: admin Category: Detector, Measurement, Microcontroller, PIC, Project, Sensor No Comments →

The project shows you how to build ballistic chronograph based on PIC18F13K50 Microcontroller. The project only been tested with a paintball gun and it is relatively simple to make. It also can record the rate of fire at which a device is firing. The operation of this projectile velocity meter is rather simple, there are […]

Arduino Speed Detector on Flash

This speed detector uses two photo resistors paired with laser as a form of trip wire. The Arduino Duemilanove with an ATMEga328 captures the tripping action and calculates the amount of time between when each sensor was tripped. By dividing the distance between two trip wires with difference time value, you will get the SPEED.
