Hi Clive. I'm a retired Openreach engineer and I have boxes of these. There are in fact three types used. The two way that you used, one the same but has three ways (maybe good for end of line and a two way type that you put over the top of a pair and when crimped will cut of the excess wire saving you from having to trim the wires level. If you would like some please let me know. I can also show you the TDR fault finder we use and methods to find and range earth or battery faults using a three wire test. The testers in use now have all these functions on one device including a high voltage insulation test, spectrum graph ( I would not go so far as to call it a spectrum analyzer and one other great feature. We can use an end of line tester unit or by sending a dtmf string we can use an end of line tester in the exchange. These can disconnect the pair from the line equipment, Loop out the line and send a modulated tone to identify pairs in congested junctions. The exchange unit is also able to perform a pair quality test. This will isolate both A and B wires at the exchange and run a test on each leg for earth or battery faults. The test also emulates a data stream and can identify any REIN and SHINE problems and show a full range of frequency tones used by VDSL and ADSL. It would also be great if you could cover basic wiring including the importance of maintaining the twists on the pair so as to provide common mode rejection. I think your viewers may like to learn a bit more about how high speed data services are provided and maintained. If I can help in any way please let me know. Keep up the great work :-) Stuart

From someone who worked in Canada as a display fireworks pyrotechnician, the common setup is parallel. My experience was always to twist together the leads and they get put in to a speaker connector on a large firing board which usually supported 28+ individual groups of fireworks. These boards would be connected back to the firing controller with a large parallel cable and regular 14-3 home 120v wire hooked up to a car battery.

Also of note: When setting up displays, DO NOT use a standard stapler to fasten down long runs of fuse, the impact of a regular stapler hammer on the staple can create a spark which in turn can ignite the fuse line. There are specific Pyro Staplers that are constructed from not ferrous materials that will not cause the hammer impact spark. I got to see the results of this phenomenon first hand when someone wanted to help speed up a display setup and grabbed their regular stapler...OOPS! Lucky the incident was isolated to a small portion of the display and didn't cause a total meltdown. Needless to say, safety watch was on higher order after that.... huh, imaging that...

But for the parachute charge, my "goto" igniter is a flashbulb(AG-1) coated with a pyro compound. I've also used quite successfully christmas tree bulbs modified for the occasion.

Hey Clive, I actually did set off a maroon prematurely with an RF device - I had about 90 feet of cable spooled onto a reel between the maroon a few feet away and the "detonator" - 12v battery and ptm switch - in the core of the spool, but the battery was disconnected to prevent early detonation. We were using licensed radios to communicate on site so transmitting at about 5W erp. I keyed up while holding my radio near the spool of wire and the maroon went pop! - An anecdotal incident for sure and not an occurrence that I've tried to replicate, but certainly food for thought and it affected our future use of maroons.

The radio quality certainly has nothing to do with it, since crappy radios wouldn't transmit at massively higher power than expected. The current in a 50 ohm load is 300mA at 5W, so if the entire thing had by some freak accident a low impedance for your TX band, it's not totally unthinkable for a sufficient current to be induced. Seems highly unlikely and weird, but not impossible.

mysock351C Is CC what they're actually triggered with in the real world?

Are they normally driven by a straight up CC or ramped up to a V or C limit and then held?

FWIW, when I was shooting pyro back in the 1980s, we use Atlas squibs that were guaranteed to fire at 150ma +-15% if I remember correctly. They were also guaranteed to blow open. We did typically wire squibs in parallel rather than series. If we had a big shot, like 20-40 squibs, we'd use a relay box with a 12V gel cell battery within about 50 feet of the squibs to be sure that we got the shot. Usually though we only had 1-2 squibs on the end of any long run, so had no problems running a couple hundred feet back to the firing box.

Chances are the old connections have failed one by one over the years, your terminal is not well protected from water, or the tech didn't know what he was doing.

I've been blowing off 5 gallon bucket bombs using cacium carbide for years. I like using piezo barbecue ignitors. There's no physical contact at the ignition point and they are very reliable. Bucket bombs are the biggest bang for the buck anywhere. They are as loud as the biggest firecrackers and fireworks, at least in the audible range, they are cheap, there is no debris, relatively safe, and the buckets can be used many times. The only expendable item is the lid seal which distorts. The explosion is so loud because the bore diameter of the bucket. If you ever try it don't use it near windows, it will shatter panes.

The old "boom boom" system doesn't do that, it's a direct pushbutton switch to the battery banks, BTW we use very old skool centronics cables that go from the main firing panel or computer out to the breakout boxes which sit between mortar racks which use regular speaker cable spring loaded pinch cables to make the connections.

A buddy of mine found out the hard way that that you can't trust the continuity test to not light an electric match. He prepped a high power rocket with an I65 motor and installed the igniter in his motel room at the launch site. As soon as he touched the leads to test continuity,, the match went off, the rocket ignited, and he hung on for dear life. Fortunately he managed to hang on to it and avoid setting anything on fire, but it filled the motel with very noxious smoke. I think that motor had about 1.5lb of ammonium perchlorate composite propellent, 10 sec burn time, and about 15 lb average thrust. The smoke is burning rubber plus hydrochloric acid from the perchlorate: very nasty stuff.

They are safe until actually fired, so if the fuse is intact they can be reused. On big shows where they don't want to take stock back they sometimes add extra unfired pyro on the final shows. Disney has a pneumatic firing system for precision fireworks. The shells have a smart circuit that is attached to two wires. When the show begins the system charges the shell's capacitor and requests a sample of the shells internal clock frequency. It then sends a command back telling it how many clock cycles it's to count before firing. When the shell is about to be fired the system sends an arming code and then triggers the air cannon to fire the shell. If the shell detects it's lost power it knows it's been launched successfully and starts counting down until it fires. If it detects that power is still applied after the time it should have been fired in, it goes into a safe state automatically and waits for further commands.

bigclivedotcom But what if the match fires, but the pyro itself fails, doesn't that present the same hazard as a failed amateur fireworks piece? Also that Disney systems seems prone to ground level firing from a power outage.

John Francis Doe cheaper stuff is just doused in water, with more expensive stuff they wait until it's safe and then analyze whether it can be re-used in another show or must be either destroyed or taken apart and recycled.

Shells are left to the end when you de-rig, partial cakes are just put to one side and made sure there is nothing still smoldering. We used to have a mirror on a stick for looking in mortars. Nearly all misfired shells are reused, you use add a new piece of quickmatch to the lift. However if rigged correctly there are very few shells that fail to fire and it's normally down to either an igniter being ripped out by another shell or someone forgetting to wire them in. We wire all in parallel, this is due to the inconsistent resistance of igniters.

Don't rely on a conductive path being still viable after an ignition; have a system that puts out enough current to run igniters in parallel, not in series.

So Clive, are you using this as an excuse to starting to make your Xmas cards this year? They'll be nice and dangerous.... 😉 Also I'm going to have to modify my firing box so it's got a continuity switch / LED in it, I forgot it when I made it.😷

I just wonder if these work more reliable than those rocket igniters. I remember getting a pack of them and 1 in 5 did not fire let alone light the rocket.

Clive do you remember scotch locks that worked the same principle as the communication joint.,used a few of those back in the day on my cars. I wonder because you put the current up slowly the wires on the first two would act like a resisters and as the last one blew it would heat up above the resistance of the other two from the heat of the explosive and have dumped the most voltage across it. This would be interesting to observe with a voltage meter across each one as they blow. I may be going down the whole wrong track.
@spudhead1696 жыл бұрын
To possibly mitigate the match firing open circuit, could you not connect something like reasonably hi-power 3 ohm resistors in parallel with each one? Then blast them with a lot more current? If the current pulse is short enough it shouldn't blow the resistors and any match that failed open would be bypassed.

The PROOF of faulty electric matches (igniters) was ON THAT PAPER! Note the pattern of the discharge. The center had a good rounded pattern (and fired 1st) with the 2nd firing at elevated amperage and leaving a slightly misdirected pattern, and the 3rd to fire was loop sided in discharge. Where ever you purchased those from, has poor QC and is producing low standard product. Repeatability is key to those, and with that manufacturer it's not likely to be found!

Could it be that because you ramped up the current slowly the first one blew but then the wire is in open air which allows it be cooled. Then then next one needs more current as the first is heating the air without blowing then a second blows then you have 2x wires being cooled by the air which then needs even more current to pass to get the same heat in the 3rd one to blow and when the 3rd one blows the wire is hot due to the explosion and the higher current is then able to blow the open. (Would they all fail open at higher current?)
