So I'm making my own grenades...

[Jez_Armstrong]

If anyone has followed my previous posts on other social media you'd see I made a distraction greande this week which is basically a personal alarm inside a 3d printed shell I designed, it's cheap and cheerful, won't break the bank and it bounces (Printed in PLA which glows in the dark and TPU for a more friendlier rubber effect) , I thought it was a great idea and I'm going to test them out this weekend, the only concerns were the DB levels (which I've now got down to 87db from 114db) and that it would be continuous untill its turned off but nevertheless it should make for a good distraction once thrown into a room on a normal skirmish day and people wonder WTF that thing was that just went off and as they look around you breach the room and attack 🤷‍♂️ (see video below) 

 

 

So this got me thinking about making another grenade, my Mk2 version which I've not seen in the market before 

 

This one will have a rechargeable battery via USB, an on/off switch and an armed button, you'll have a speaker and the ability to record your own sounds on it for 10 seconds, so you could have 5 seconds of silence once you press the button (primer/fuse) and then 5 seconds of multi bangs sounds, or you can record a voice that says something stupid like "they are coming from behind us" which might make some stupid people turn around 

 

Or you can have something silly like this 😂

 

 

 

 

 

But it's something I'm currently developing, I only had the idea on Sunday and by Wednesday (today) I have a working mk1 prototype and the Mk2 version should be ready by the weekend, at the moment it's a little quiet at 0.5w but I'm adding an inline amplifier this evening which should bump that up to 3w and also designing a grenade housing for it to all fit into 

 

Any feedback so far will be greatly appreciated

These are amazing pieces of work: I look forward to seeing them used one and then banned at my local sites.

I can see mk1 not being very popular but what about Mk2? 

[Tackle]

Yeah the first one is just annoying, but the Mk2 definitely has the potential to be considered a timed "grenade" of sorts, especially useful for those urban sites that can't have any form of pyro ?

Will you be bringing these to market before or after the Molyneux MAS-G?

They've had 8 years to make theirs, I think their customers would be happy to have one of my mk1's than carry on waiting 😂

As one of the original backers...yes, yes I would be.

[Dan Robinson]

The first one would almost certainly be shown the underside of my size 12's.... The second one could be great - would the message be recordable?

[Jez_Armstrong]

Yeah the mk1 does seem to be annoying but it's where I started the idea 

 

Yes you can record your own audio up to 10 seconds

I can already imagine some of the audio being used 😂

The world will have ended before that happens.

Hm. I don't know if this kind of this grenade is gonna be allowed on sites. Basically it's just loud but does nothing else.

 

But there could be a market for impact grenades which uses a loud bang noise if it hits a hard surface. Making different versions regarding dB so more sites could accept it instead banning everything.

 

Imagine not spending money on primers..

Well that was the thought, you could record your own bang sounds so it would be the same as a reusable grenade

Not every site allows pyrotechnics, either insurance issues or the public in reasonably close proximity, so a non explosive relatively low volume grenade maybe just the answer those sites are looking for in order to inject a further element of realism in to their games. 

And if it says "BOOM MOTHERFUCKER" after 5 seconds, even better🤣

I feel the need to point out Ive moved 5 times since I backed that things lol.

I've only moved once but hey...you do you.

I think I've figured out how to make the mk1 play for only 10 seconds also, I wonder if that will be ok

[Jedi_Master]

The glow in the dark and flashing light would be excellent in dark CQB environments for recovery of the grenade once thrown. Although it would have to kept from view before use due to the glow.

For me no, I'm not big on the whole distraction device idea, especially as it starts sounding the instant the pins pulled.

The whole grenade thing with a a timed silence allowing you time to post it through a doorway or window definitely sounds like a game changer though.

Yes, I have saved a lot over the years by not buying primers and just using a cardbord Mk5 thunderflash .

I’ve been meaning to hop in since seeing the title of the thread, and making my assumptions that is was about DIY pyrotechnics, particularly as I was seeing mk1 & mk2 in the updates but I’ve been busy in the lead up to today

 

 

As per my accompanying photo I can just about squeeze in some time to properly read and comment …..

 

 

I’m relieved that @Jez_Armstrongis fairly safe from self destruction and a terrorism arrest 

 

I’m liking both ideas. 
Mk1 makes good use of an existing product

Mk2 builds on that

 

My main dislike of mk1 was the need to stop it, but it seems like you can crack that

(as a site prop I’d be less worried about it being on until reset - but it would depend on the environment as an alarm in a confined underground room is a bit different to woodland)

 

Good idea, good fun project.

…… and it’s up to the site if they let you use it

 

The key problem with devices is losing them, shutting them up and retrieving them

 

You appear to be thinking along those line 

[Jez_Armstrong]

Thanks bud that means alot! 

 

Yeah I don't trust myself with actual pyrotechnics, just about trust myself not to pick up a hot soldering iron wrongly these days 😂

The MK1 doesn't do much for me.  If it had a delay then boom sound (white noise) for a few seconds it might be worth pursuing in my view.

But the MK2 definitely has marketable potential as long as its priced right and up to the point a certain country makes a cheaper copy...

 

My input would be if you could give it a thin rubber/neoprene outer to protect it and the victims.  That would help it being accepted at sites (most allow rolling BFGs and dropping through windows)

Great minds I'm currently trying to fit it inside an inner tube 😂

 

It's not going well
