LED lit/controlled cannons

[Bootes]

Here is something I have been toying with. LED lit cannons. Controlled by an led flasher unit (from an online auction site) with sixteen led's and eleven programs. Each led has four or five fibre optic cables held in place with heat shrink. The cannon has been drilled through with a two mm drill this also removes the fixing pin on the back of the cannon but will be held in place with the fibre optic. Smaller F/O could also be used. With a  bit of playing around with the placement of the cannon end of the F/O broadside firing patterns can be achieved.

 

Is it too cheesy. Please let me know what you think.

Hi Brian, thanks for the feed back.

Yep, I have also thought about flickering LED's (1.8-2mm) for the cabins, any lanterns that might show by stairs, ship's wheel and binnacle and of course the stern lanterns. 

Now what about sound !!!

Hmmmm

Bootes I am looking for a source of flickering LED's for the cabin of my current build. If you know of one, please let me know.

 

BTW, re: the sound. Little computer speakers hidden somewhere in the model won't cut it. What you need is a massive subwoofer under the table and a smoke generator. That will really surprise people who are expecting a tinny sounding "boom" to come from your model

Cabin and gun-deck lights good. Unless you make smoke and have a report with your cannon lighting, to me it would say, has good understanding about fiber optics, can produce some very fine work on models but hasn't a clue about gunfire. Being an Old Gunners Mate my opinion may be a tad bit bias.

There are several ways to have flickering LED's.

Flickering LED's or standard LED's controlled by a flicker unit.

I've had a look around for very small 1.3mm flickering LED's but can only find them in 3mm on a well know auction site (not sure if I'm allowed to use the name).

I have found two very small flicker controls on the same site, one for a single LED and the other controls four but I should think a couple of extra LED's could be added to each unit.

LED range in size from about 1.3mm upwards and most come with a resistor.

I have never posted a link before so I hope these work.

Murton Scale Miniatures, 5mm LED: Link

Very small LED: Link

There are plenty of LED lighting solutions on that site.

 

I have also been playing around with cannon fire sound effects on the computer,and there are a few sound samples on the net which could be loaded into a small cheap mp3 player. Cornwall Model Boats sell an SD card 'Galleon With Cannon sound card' for £9.98: Link

I think the smoke might be beyond me.

Hi.

The smoke can be made by using model steam loco smoke oil.

A heater unit( nitchchrome wire ).

A shot air supply ( relay with diafram )

A Arduino nano providing the timings.

Process is :-

Relay pulls back.

heat oil for 5 seconds.

release relay.

Wait for next shot..

 

Have done this on a 1/12 scale cannon with a impressive puff of smoke forming a ring as it leaves the barrel.

 

As for the Flickering LED's I did a how to some time ago. http://modelshipworld.com/index.php?/topic/2806-flickering-lights/?hl=%2Bflickering+%2Bled

If you need a small drawing on the smoke.. I can do this if wanted later tonight.

 

Regards Antony.

Yes Antony, I saw your thread about flickering LED's with an Arduino board. To be honest I am a little intimidated by that solution, but I did look into it closely. I am currently wiring up my latest project for LED lighting (see my signature), but I decided not to bother with the flickering effect.

There's some articles here on LED setups:  http://modelshipworldforum.com/ship-model-furniture-and-deck-fittings.php

i would love to do something like this - but - i have found the actual build difficult enough without all this extra electronics, but i love to see and admire actual finished builds with this incorporated

[shoule]

 I'm an old gunner's mate, as well, and I think its cool; lots of possibilities.

 Keep playing with it; I'm fascinated.

Keith,

just a thought shouldn't the sound also be to scale. I've knocked up some sounds on the computer.One for the really big and another for the light, the heavies have a really reverberating sound that rumbles on after each shot, still needs a bit of tweaking to get it just right. Unfortunately I can't post the sample for feed back.

By the time I'm finished I'l have that much cabling coming out of the ship. I didn't know they had towed arrays in the 1700's.

[Keith_W]

Bootes you are probably right that the sounds should be to scale. But the thought of causing involuntary bowel actions when I am showing off my boat tickles me pink. As you may have figured by now, I am not a very nice person

When we were trying to record the sounds of a 40 MM Bofers firing, Mt 46 aboard the Harnett County LST 821 in RVN, we did not get much, the concussion at the mount would make a splat sound as the shock wave tried to destroy the mike.  With the recorder at Mt 46, a good recording of Mt 41 firing could be obtained, of course that would be a little over 200 feet away. Kind of disappointing not being able to record the gun sounds such as feed pawls, empties going down the casing guides and other sounds that a Mount Captain should be listening to.

By the way, if you look for Antal Dorati's recording of Tchaikovsky's 1812 overture, you will find a recording of a real cannon from 1775. Amazon link here: http://www.amazon.com/1812-Overture-Capriccio-Italien-Wellingtons/dp/B000PMFTE0

 

The cannon appears first as part of the music, then in the next track it appears by itself.
