1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

new night vision build

    In a previous post I showed my first night vision build, video below but having seen so many different designs I now want to try something different.

    What I am looking to achieve is night vision with inbuilt DVR to record HD videos of the shots I take. My list of parts are:

    1. Raspberry Pi (google it as it is not a food group)
    2. 16gb USB stick
    3. Raspberry Pi Noir camera
    4. 6000mha USB battery
    5. 3.5 TFT screen (cheap China reversing monitor)
    6. 16mm lens for the Pi camera

    Being the geek I am this is going to be ambitious to saý the least but I think it will give me what I want. The only thing I want to change is the way I mount the camera to 'see' through the scope as I think the my current way (again see video) is via a silicon hose but other designs appear to have a more robust version using a weaver rail type adapter.

    I intend to try and get this all built up and working by the end of this month but might be sooner if I can get the parts I need quicker.

    Any other considerations that I should make this time around?

    Happy New Year!!!

    Welcome on board. DIY NV = untreatable addiction.

    I don't think your camera will be good enough for the job. Have a good look at the boards and camera specs/recommendations before you purchase.
    All the best.

    The reversing monitors are almost always 12 volt, presumably your battery also has a 12v socket. There are some cctv type cameras about with hd resolution, they may have an hdmi output, possibly usb but I've not heard of anyone using one so far and I don't know what their low light performance is going to be like.
    For mounting the camera you could consider using the plastic waste pipe and fittings available from B&Q etc in different sizes and in black or white. If your scope has an internal thread on the eyepiece you can also use camera filter adapters, particulalry if the camera lens is also threaded - you will probably need about38/40mm between the rear glass of the scope and the front glass of the camera lens.
    You might also consider using one of the small dvrs which often have a reasonable screen and the ability to record in hd, this is usually limited to 720p but that will probably match the camera anyway.
    Have a browse around some of th 'fpv flying' sites where you should find some useful information on recorders ans also cameras although they tend to fly in daylight so don't have the need for good low light performance.

    My option is to use a standalone DVR which takes its video signal via a splitter from the other screen/cam, it tucks away in the battery pouch and can record up to 20GB of MP4.

    terry already on the waste pipe size. I have got the initial workings done but I am still considering now the camera. Whilst the thought was to use the Raspberry Pi plug in version it is, as some pointed out, not up to the job. My mission really is to have a self contained unit with battery, screen and camera to just push on the scope. Here is my updated version for now. I need to order more parts.
