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.

  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.

    Sorry if this is a dumb question but if I was to tidy my night vision up into project boxes. Can you use a 3.5mm jack cable to connect the two together.

    So basically can I wire a jack socket into each box and then plug a jack lead in to connect them.

    If so what pole? 3 or 4 thanks

    I used 3.5mm jack/sockets to connect my cmos board camera and 12v cut down t20....used a 3 pole for the cam pos/neg/video and you can use the same for just neg/pos...just make sure the male jack is connecting to the right contacts within the socket.

    No problem,its my 1st time,having a few is issues atm with fitting camera to scope as i got the floplast 40mm end and the coupler however the camera doesnt fit in the back of the solvent weld end cap also the floplast says its 40mm but the internal of coupler tube is actually 43mm and even has 43mm stamped on it so not sure where they get 40mm from lol, as its 43mm it loose around my hawke scope and i dont really want to put loads of tape around the eye end.
    Ive only just got the bits to make it so will def update ones done and resolved

    You can use stereo type jack plugs and sockets but be aware of the possibility of the live contact touching one of the others when connecting. It's better to use a proper plug and socket if you can find one which isn't as easy now that Maplins have closed their high street shops. You will need one connector for each line and that will depend on how you fit it but normally 3 - power, ground and video. If you do use a jack then put a switch in the circuit and only connect when the power is off.
    Another note of caution, if you have a torch on the same power supply as the camera/monitor there's a very good chance of interference on the video signnal caused by the power modulation in the torch driver circuit.

    My contraption runs of one single lithium batt,screen,cam and t20 ir which uses a 12v driver (can't remember the name of it) and a dimmer for the t20 and no interference at all...will dig it out later for some pics but it was a long time ago I knocked it together and can't remember how :oops:

    Have you got a volt meter?...if not get one as they're handy for testing which wire goes where etc as well as testing for good/bad contacts etc.

    My 1st nv kit attempt done,just got to put the small project box on back of floplast to take the camera body and female jack socket,to allow it to be linked up with a single male male jack lead. All seems to be working ok,just a few tweaks to sort regarding ret image. May have to swop the 16mm lens for a 12mm as it seems abit large on screen.

    I think I might have it figured out all though I've being told to wire the switch in between the jack and charging port so I can charge it turned off
