    The working principles are sound, but the way he goes about it is funny.

    I like the guy! There is a certain made scientist element about him.

    On the darker side the device he makes is potentially a very dangerous weapon. Ever a dangerous experiment in the hands of the someone who lacks electronic knowledge. The problem is, it's a continuous duty device, it should shut off after a second and then only work if the button is released and then repressed.

    Tip : a coil on plug coil is more compact and has a higher turns ratio. The whole lot fits into piece poly pipe.if you use a cop and 6 lithium iron C cells (9 volts is fine). It's best to replace the relay with transistor and a 555 timer one shot circuit.

    Ask me how I know.

    I dabbled with electronics when I was younger and was always zapping myself.

    Icon14 Good one HRE and Robmac!!

    Loved that video, now I am waiting for the Robmac comparable video demonstration of his improved device (Pics or Ban?) complete with whizz bang expletives

    Thanks for posting HRE!

    I am sure shane could build one and find uses -rocket powered dog detterent? but then again, not good to have one lying around when wives could pick them up and apply them to you know who

    Shirley he can't be serious! Putting 100v ac on an automotive coil, pointing to results and, for the climax, measuring a live high voltage gap with metal verniers!!!

    Damn funny. How he can subject himself to the results of the "mistakes" he makes in the cause of entertainment is amazing.
    When disposable film cameras with inbuilt flash were popular the local kids would use the circuitry for shock units.
    Voltage was lower, only 330V AC but the capacitor held quite a charge.
    I collected many of these cameras from mini labs and used to bunch them together to make large light boxes.
    Had an article published in photographic magazine on the use of them.

    :
    I agree with robmac here. Yes, the "mad scientist" chap is entertaining, for sure

    Call me a party-pooper and a nervous-Nellie ... but goodness, it looks kind of dangerous to me if someone with limited knowledge goes connecting up mains power to an automotive coil to see what fun they can have ....

    Not keen to do that. Those aware of the risks in making and using such a device should also have the knowledge to build it.

    It looks funny on the video, but a lot of it is "hamming" I'm sure.

    I don't want having created a cardiac arrest on some inexperienced hobbyist as part my works.

    These devices are potentially lethal on the bench, less so once the output electrodes are installed. And his design is very rough and ready . So my suggestion is to think carefully before building such a unit.

    I don't blame you for wanting to be cautious. I've been hit a couple of times with HEI at 40,000+volts, and lemme tell ya, it stings a bit. Fun to watch dude play with this stuff, but not for the average guy who barely knows how to change a fuse.

    For those who want to experiment. The coil on plug ignition coil driven by a Bosch darlington transistor ignition module to do the switching is the go. No need for capacitors or suppressors.

    You drive the module directly from a 555 timer with free running square wave and use another 555 as a "one shot" with an inhibit time.

    9 volts is quite satisfactory but it needs to be low internal resistance source like a NIMH Battery or SLA battery.

    Those who may want to experiment should also be aware that they are Category R weapons in Queensland and I suspect similar will apply in other States in Australia and as such, one can not even get a licence to lawfully possess one and making one is manufacturing a category R weapons, also illegal without armourers licence. Most likely scenario for getting caught is when someone gets hurt or one upsets the Mrs/significant other and they do the dob in on departure.

    just out of curiosity....
    exactly how many volts would typically be outputted by a coil, say from a morris minor, linked to a 12 volt battery?

    (I may, or may not know, how weird it makes your elbow feel for hours afterwards)

    Proper standard 12v coil (which is actually about 8.5-10 volts once the power in runs through whatever resistor pack it has), in good nick, about 12-15000 volts once those points open and the magnetic field within the coil collapses. That's enough to let you know it works.

    Maybe... but we are yet to have a toddler in pram to shoot mother on shopping trip.. so not sure who is worse off. Maybe we don't have a pressing need to arm the whole civilian population just yet...?

    Who know's? There WILL BE at one point......a third World-War."Probably" BEFORE 2020. All the 'Signs' are there. Can't worry about little things like that though. Just live your Life and fulfill your dreams before it's too late.

    It depends how you define the experimental unit.

    I choose to call the unit I built "an experimental portable spark generator to create ozone by creating a corona electrical discharge in oxygen . My reason for building it is to research the efficacy of removing toilet odours by the process of ozonation disinfection".

    After I have completed, evaluated and documented my research I intend to submit a paper Engineers Australia for peer comment.

    I daresay there are hosts of experimenters could cite similar reasons for building what is essentially a spark generator.

    Why ? I don't need to "test" anything (except my project) I just present my engineering credentials.
