    Hi everyone

    This is my first post, I have a project in mind that is currently beyond my skills... that said - how do you learn if you don't push the boundaries?:confused:

    I do a fair bit of air rifle shooting and have been making metal targets for a couple of years, however the targets are static - they don't move, as real quarry would.

    My project is to create a device that will pivot a target back and forth a few degrees to simulate the bobbing of a pigeon.. for example.
    ie not a liner back and forth, but a semi random movement to prevent calculating the next bob.

    I have three questions,

    1. Am I in the wrong place? if so, please accept my apologies.
    2. Will the be a seriously advanced task that realistically will be too much?
    3. If I have survived the first two questions... where do I start?:eek:

    I've very practically minded, building a kit car from scratch (so handy with tools) and a web designer (so capable of scripting languages etc) and happy with a challenge and steep learning curve!

    Any advise greatly received!

    Thank you for taking the time to read my post:D

    Use a DC motor with either an H-bridge or a DPDT relay for direction control. A slow pulsing clock will switch a random logic pulse (hi or low) to change direction of the motor. The motor needs to be slow, so you might use a geared DC motor.
