    Hi all.
    I had a circuit corrode and after consulting my local maplin specialist have been told several components have had the part numbers removed so i'll probably be better replacing the boards completely. I unfortunately have very limited electronic knowledge so I'm hoping for some guidance on this if you can please.

    It's basically a send and receive relay from what I have been told, what I need it to do is send the signal by pressing a button to the encased receiver which will in turn activate an electromagnet releasing the device. An on off switch on both parts would be beneficial too. Also the receiver has to fit in a gap about 100x10x20mm roughly (minus the power source and the magnet), I may be able to file a little more room in but it won't be much and I need a range of roughly 30m to be effective.

    So can anyone help me out, maybe draw me up a circuit schematic to work to and component list?

    Many thanks. Matt.

    We can probably help, but we just don't have enough information to tell you much right now.
    Is this a home-built device, or can you give us a commercial model number of the device with maybe pictures of what you have, and a more complete explaination of what you need to do.
    I know what you wrote makes perfect sense to you, but we're going to have a hard time picturing in our minds, what you're explaining.

    I'll upload tomorrow from my pc as I'm at work atm. I'll get as many detailed pics as possible but as for model number I have no idea as they are second hand. Thanks shrtrnd. Matt

    Type: wireless relay remote in to ebays search engine. There is a lot of premade stuff out there that would be a lot cheeper then to make it yourself. You might lose some quality though since most of the ones they have come from china.

    Right then fella's, sorry for the long delay in getting back on here, had 2 labours and a bike accident on my work team so been pulling 14 hour shifts 6 days a week. Yes my pay cheque looks very healthy this month lol.

    Anywho, down to the nitty-gritty.

    First off, don't be alarmed, these are just toys after all. Expensive and realistic toys but toys none the less.

    This is the firing unit opened up with the circuits and covers still in place (minus the battery cover).
    IMAG0646.jpg
    And when fired. IMAG0647.jpg
    This is it stripped down showing the space I have to work with, I can dremel out the left hand side to fit in a 9v square battery and the space on the right can also be dremeled but I would prefer to not have to.
    IMAG0648.jpg
    IMAG0649.jpg
    So the concept is simple, when armed (and all safety's are removed) and the transmitter is held the magnet is powered causing the trigger to release and therefore firing the weapon. Once the transmitter is released so too is the trigger as the magnet no longer draws power.
    One transmitter needs to control two receivers for simplicity and I'd like power switches in both transmitter and receiver units as they don't get used every day so I don't want to be wasting batteries whilst they are sat around.
    I tend to be around 15-25 meters away from them when firing so range isn't massively important to me, about 30m will be plenty but the circuits need to be idiot proof (with me being the idiot) as my electrical knowledge pretty much extends to being able to tell you the difference between a battery and a bulb.
    That said I can solder pretty well and can follow instructions so can anyone please A) advise/design a couple of circuit boards that will fit this role and B) explain or provide a simple diagram on how to wire them up so they work (power-board-power switch-magnet/trigger)?
    My only other addition is that in the transmitter I'd like to include this as the power switch (as I can put a missile style cover over it which will look pretty cool) but as you may be able to see from the picture it has six connectors underneath for what I do not know? Which two do I use as a basic on off switch (left back to right front etc)?
    IMAG0654.jpg
    I realise that this is pretty basic by comparison to some of the questions I've seen uploaded but I would really appreciate some help if anyone can.
    Many thanks,
    Matt

    I think the moment you used the phrase "firing the weapon", most of us here are going to take a step back.

    It's also the kind of thread we close.

    Hi Matt

    To follow on from what Steve said

    Tho your project may be and probably is completely innocent ... we don't know for sure ... not being there to see it
    and I'm sure how you could see how in these days of terrorism etc how it could be used for bad
    and not necessarily by you ... Someone nasty searching the www for " remote triggers" could find
    this thread and get all he needs to kill a bunch of people.
    None of us here ( including you) would want to live with the knowledge that stuff we posted on here was used for evil

    I hope you can understand our position. In a nicer world years ago, it wouldn't have been an issue

    Regards
    Dave

    Tbh I can see your point, the whole concept of airsoft is in the realism of said "weapons". There are hundreds of rules regarding the violent crimes reduction act (vcra) as well as plenty of defence against it all of which I can provide. That said I can understand the hesitation in putting that info on a public thread, I really didn't consider the implications of what I was asking. Thanks for your time, Matt.

    I've read of paint-ballers and laser-light playing kids getting shot by real cops for less than this.
    If you set up yoiur 'fake' claymore mine anywhere, .... You better be wearing a vest, cause you're liable to anything, that anybody wants to do to you for the threat.
    I guess I can understand wanting realistic play, but for cripes-sake, A Claymore Mine? Are you out of your mind?
    Couldn't you come up with something that won't create a panic by anybody who recognizes it?

    You realise the sport is played on actual sites dedicated to it lol. I have no intention of setting them up in asda lol. This is half the problem, there are idiots in the world that have got themselves shot/arrested by waving a RIF in the air or holding up a shop with one which has caused the introdution and reduction of limitations in the sport making it A) harder to get into and B) harder for outsiders to it to understand. Seriously though, I won't defend further, I can see the point made.

    I know what you're saying. Glad to hear that device only comes out of the bag at some dedicated site.
    My point is, that I used to deploy those things; and if a cop or neighbor recognizes it out of the bag, I don't care where it's at,
    things can turn bad for you badly, very quickly.
    Good luck with your project.
