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.

    Hi you can burn the insulation of with solder iron if you dont have good strippers. Dont forget to check for ir cut in camera
    A pinkish square of glass over sensor
    Again use iron to remove But take out iron tip and just use the hot barrel to heat glass .plng of with craft knife or the like
    The larger dia barrel spreads heat, dont cook it bit of heat at a time

    Well guys heres a bit of a update on my nv build

    With a very kind offer from frog who sent me the correct wiring cables and conectors i did not need to solder anything......many thanks frog!

    I had bought the wrong bcn to phono conector and my new (correct one) came today which i instantly conected to the yellow cables from monitor and camera.

    But still no joy as no picture on the screen, i tried the white cable to receive the same disappointment.

    Battery light was on but i have set it away to charge a bit more just incase it didnt have enough juice in which i doubt.

    Any suggestions would be much appreciated, cheers guys[​IMG]

    Nothing wrong with the way they're connected, so either something is faulty or you need to change a setting on the monitor AV1 or AV2 switch is favourite.

    The screen wont light up until it detects a video signal, you have it wired up correctly so it must not be receiving a signal, the usual culprit is BNC connectors, they are absolute sh*te! the worst connector ever made IMO. I wired a CCTV system up and had to replace every single connector again as they were so bad (chinese copied crap)

    Check the little pins in the centre of the BNC connectors, I had problems initially with my NV setup because of this and bought a whole pack of connectors, half of them don't work... :rolleyes:

    If it's not the connectors you may have to face the possibility that either your camera or screen is FUBAR!

    Gareth - Just edited to add - sometimes the power splitters are also sh*te, if either the screen or camera doesn't get power obviously it wont light up, I had to buy a few splitters too as they had intermittent faults, see if you can power from an AC adapter, I keep one of these multi-voltage ones with different tips for testing purposes.

    Good advice there Steve. :)

    That's why I always chop off connectors - you can't beat a soldered connection. :D

    hi if you have a multi metre, set to 12 v and power up check output from cam by putting red probe to centre pin of vid out on bnc and black probe to earth collar on bnc if all is well should read 1.5 ish volts,if nought check cam power input is ok then work your way along all cables and cons BEST ADVICE IF YOU DONT HAVE A MULTI METRE GO BUY ONE, they are about a 5/ 10 sqids from most store likw BM THE range etc. continuity is a very good function on these is very good to check for broken wire dodgy plugs etc the little book that comes with, will tell you how to use

    Unfortunately what Steve said is all too true, the cheap connectors from ebay and amazon are often completely useless and added to the pathetically thin and fragile wiring it can be a recipe for frustration. This is one of the reasons that, especially for first time constructors, that I strongly recommend spending the extra on the Sure24 kit as everything is there and quality is good.
    The fault finding suggested by genisis22 (Hi Alan) should lead you to the faulty component(s) quickly. You will need to switch the battery pack on to charge it, just to confuse things.
    The monitors will show nothing until they get a video signal, maybe a slight flash when the power goes on, either input will work it's just neater to go yellow to yellow.

    Cheers mate i will look for a more reliable BCN conector and pay a bit more.........lessson learnt

    I did think worst case scenario was either the camera or monitor were toast, will source a new BCN conector out then go through the process of elimination........fun fun fun

    That looks like a Foxeer camera. The smaller 2 pin plug should be for an On Screen Display board.

    hi ,< hi to you to terry> you can also check cam function by powering up cam and connecting an av cable to your tv if it has av source menu you no like hdmi 1 /2 satilite etc choose symbol that shows pair of av cables,, if you get picture the problem is with the screen or cables back to the joint you fitted to the tv, if nothing then back to original advice

    Im not sure in the make of the camera mate? It was a cheapo from china costing a whopping £13 with a 16mm lense.

    Sorry for sounding daft but i dont know what you mean by on screen display board?

    Cheers

    Gareth,

    Have you got another screen? or can you wire it to the yellow TV in phono on a televison?

    Need to work out whether its a camera or screen fault now IMO.
