Title: DIY smoke generator
Post by: Stoker04 on February 15, 2015, 05:47:22 pm
Hi guys, a few questions.


My corvette runs from a 6v battery, and I wanted to add a smoke generator, looking around I can't find a water unit (as opposed to a oil unit) that runs off 6v.


I was thinking of making one, but wanted to ask if anyone has tried this or indeed does know of something. I could buy.


Thanks
Alex

I've seen some quite good ones made with inexpensive humidifier/misters bought of fleabay.  They operate at USB voltages.

Have a look on the Wicksteed Park web site under tips from the man cave, I think that one cost less than £20 all in. I should add that I use it in one boat that runs on 6v, the unit draws its power from a small12v sla from component shop that will fit in most small spaces and lasts for about 1 Hour stepping up to 24v.


I have another boat that has no space to spare and the unit will work quite well off the motor battery, a 5000mah 7.2v getting around 19/20v out of the step up unit, so just play around,see what you can come up with.

The issue is that most "sonic" humidifiers, or fog generators run on AC, or 18-24v DC.
I have seen some small coffee cup sized humidifiers that use a cotton wick to draw water to
the disc, but have not purchased any of them to use as smoke generators yet. Might be worth a fiver.

Hi .
I have made several smoke units in diffrent sizes . I was asked this question can you get one to work off 6v. I try the voltage converter on a 6v bat at max gain . the converter would not work . Sorry the conters i have seen will not go down as low as 6V . The foggers new 24v to run them . You could look down the route of water vappor cigges ,they might run at a lower voltage but I do not know any thing on the stuff. Could you fit a small 12v sla bat in to you boat

Hi Alex, as you probably know there are the Seuthe smoke generators usually used on model train
Set ups. But they use oil.

Yes John I was also looking at these, number 491. I've seen a guy has installed it in his model Bismarck
The only worry about this I have is if it burns the oil too fast

If it's any help this is the V4 super smoker I have in my tug, amount of smoke is varied with the throttle this one is 12 volt but a 6 to 8 volt is available it's made by a guy in Australia who sells them on ebay, and is without doubt the best smoke gen I've seen, it runs for a very long time on a 15 mil fill of fluid they aren't cheap but you can spend 24 pounds on a tiny seuthe that runs for a few minuets, the seller goes by the name Chopperflyboy on eBay and I got mine in 7 days well worth a look  :-))

Hi Had an oil smoke generator in a model loco once . Removed it after 30 min of use. What I found was from the chimney back there was a film of oil on the top of the loco .this was deposited by the smoke generator. My self I would not touch them with a barge pole .

One of the seaside arcades near us had a kiddies train ride
It puffed and puffed as it rocked back and forth and deposited an oily film on the kiddies. That was a smoker fed by a distillate.
However good the smoker is there will be a deposit of oil on your
pristine model.

The thing that I found with the small Seuthe type they do tend to crackle and spit oil Resulting
In oily deposits on the model.

So I've started experimenting and getting some bits together.


I've purchased a small project box off eBay which will act as the oil reservoir ( the oil is going to be standard baby oil from boots)


A small computer fan that runs off 3-6 v dc
Some heating element wire, from a friend that builds E cigarettes
A small length of fire rope (the fibreglass style rope found on fireplace door seals) ( this will be the wick)


I still need to purchase some plastic pipe and right angle pieces to make the "chimney"


My next question is this


My power supply is a 6v dc 4ah lead acid battery (graupner)
I have been experimenting with the heating element, I need it to create enough heat to make smoke, but also balance it so that there is not a massive current drain therefore making the running time an acceptable level.


I still need to establish how I will connect the supplies for both the fan and the element, some people suggest connecting it to the output on the ESC , I like the idea of this as it will give a realistic amount of smoke when the motor is running, or I can wire it in directly having it run constantly.


With regards to the resistance of the heating element, essentially this is just modified by the amount of coils I put in the wire (wrapping around a small screwdriver) at the moment.


At the moment of testing I have 2 ohms resistance, but this has a huge current draw, does anyone know the average resistance of a 6v smoke generator coil? I've been looking at Seuth model train ones and they suggest around 15-20 ohms

I think you are looking for around 5 ohms then that would be 1.25  amp. I use a Maplin 10 watt resister 10 ohms for a 12 v unit that i make. So if you was to use a 5 ohm 10 watt resister for 6 volt  i think that would be just fine. I make my own smoke units but im not allowed to sell them ?
Oh by the way if you stop the fan the unit will overheat maybe fire up! so best to leave the fan going all the time on Oil heated units. If you make a demister water based unit it is safe to turn the fan off or do what ever speed you need.

Umi,
        They sure do (Model Boats May 2013).  It is a discrete smoke effect but maybe for that reason a shade more realistic than vast masses of steam billowing out of a models funnel?  I will also work on a 4.8 volt supply, at last a use for all those spare receiver battery packs!
But, try to use distilled water.  We live in a hard water area, lots of dissolved minerals and the diaphragm through which the jet of "steam" escapes tends to become blocked after a while.  Cleaning with something like vinegar seems to restore its function.

Thank's Glynn,
Good to know. I have had my eyes on these for years, but my personal builds were
a bit kiboshed by the economy, so even a cheap cup humidifier was a bit excess for
continuing the tug I started in 2009.

Back when that community shop closed...

Hi Dan, here goes......
All you need is a small reservoir, a small computer chip cooling fan, some NI-Chrome wire (heating element out of an old hair dryer will do), a  short length of dowel or similar, a small piece of WOVEN fibreglass cloth, 12 volt battery, disco fog fluid (available from Maplins), plastic or copper tubing for the flue to the funnel and a couple of screw block connectors.

To work out the length of the Ni-CH wire needs a bit of trial and error to get right, you need the wire long enough for the fog fluid to burn off but not get red hot.
Next, wrap the glass cloth around the dowel to act as a wick and spiral the Ni-CH wire around that making sure the wire doesn't overlap. Use the choc. block connectors to connect the power feed wires to the Ni-Ch wire (solder doesn't work for some reason) and place dowel at an angle in the reservoir with the wick in the fluid but not the element. Secure the computer chip fan to the reservoir. Fill  the reservoir with fluid up to the bottom of the element and connect up the power and switch on.
I have done a schematic drawing to try to explain how I did it, it's easier than it looks.

Trouble is its usually whatever is cheapest. For instance you have the 'octo' a multi switch at almost 50 quid. I have one in my electronic parts drawer with 7 channels from HobbyKing it cost me 7 quid! Mine's just a board with the connectors, not encapsulated or in a posh box, but it does the same job.

People will always search out the best and then look for a cheaper alternative- its the way of the internet.

Still trying to use just water though.
I bought a lot of JJC systems, and he started out top notch.
It wasn't till the sound systems started skipping at speed, that issues arose, and were never corrected.
For the USA, Harbor Models would be the local manufacturer, but again it is an oil system, not water.

My old 'African Queen' has been burning incense sticks soaked in baby oil for years now. Works out about 2p for 45 mins of realistic smoke. The copper funnel only gets slightly warm and the cold ash is collected in a pan in the 'boiler'. As a bonus the lake smells of whatever sticks I use, lavender, patchouli, jasmine etc  :}. No fans, batteries, wires, messy oils etc  just a bit of hassle getting the sticks prepared so I do them in bundles to last me all day. Amazing what imagination can do! O0

Hi Brian,
Thank you for pointing out that Hobby King's price on a Rx switcher at £7, that is so low, we cannot even purchase the components for our unit at that price. As a matter of interest I have looked on the Hobby King site for a 8 function Rx switch of any type and price. Sorry, but they do not sell anything that can be even described as an 8 channel switch unit of any type at any price. Perhaps your purchase was awhile ago as no one at Hobby King can remember selling them.
By the way, the 'Octo' 8 way Switcher is £49.95 and we actually sell a great many, it is very popular. Let us hope that Hobby King don't see it as they may try and sell a cheap Chinese copy for £10 or less! or perhaps not. After 28 years in the business I can tell you that cheapest is not always the best. Did you say yours was still unused in your parts drawer? ;D
7 quid! That's a steal mate. Give me the link and I will buy some for myself.

By the way, our Smoke Generator is £38.95 and uses a water based distillate, which comes free with the purchase of a unit. Plus a selection of items to make the unit more active over a longer period. :-)) The cost of running the unit for the first 30 hours is ---FREE, after that the next bottle will cost you £1.60 which is a tad over 5.3p per hour for 30 hours.

Best Regards to you and enjoy Sunny Spain.

Before anyone decides on placing a bulk order with our Chinese friends I'd point out that their seven-channel switcher can handle a maximum of 400mA (all at the same input voltage) on each channel. That's fine for lighting circuits BUT most smoke generators and certainly all the water pumps I've ever handled are heavier on current than 400mA. Graham's 8-channel unit is limited to 500mA per channel while the ACTion P62 has relays and, although just four channels, can conduct up to 3A per channel. You can also switch up to four different voltages with it.
There is also the usual caveat about Chinese QC to be considered i.e. there generally is none, and the after-sales service from these ROC suppliers is not known as the best in the trade. There is only one way to make things stupidly cheap and that is to cut corners. I prefer my corners sharp.
BTW Is there any reason why this thread is under Full Scale Ships?

I have used commercially produced smoke units and I have made my own. Commercial ones work, home mades take some serious tweaks to reach efficiency... sometimes I just channel the smoke coming out of my ears! Sometimes I channel that smoke caused by hearing about the benefits of purchasing from that great nation whose greatest contributions to the world are a stuffing great wall, fireworks, and getting away with copying the rest of the worlds product for the last twenty years, passing it off as their own and getting us stupid earholes to give them our money rather than give it to the people who have worked honestly to earn that money...
So the lesson is copy, produce poorly, undercut the quality product, drive them out of business and....THE WORLD IS OURS!!!! HA HA HA! ( Imagine someone stroking a white cat at this point..)

Have been playing around with an E cig "clearomiser"


This little gadget cost me 99p off eBay, and although the tank is small it can easily fit inside a funnel, running off a 50:50 mix of vegetable glycerine and water, the results are brilliant. A small air pump is yet to be installed but then the smoke effect could be changed depending upon the air flow. Even a "chuff" effect could be implemented I'm sure....


The clearomiser comes ready built, just solder some cables on the bottom and add a small pipe, it runs off anything between 2-6 volts although I'm sure there are lots of varying voltage ones on the market, again with varying tank sizes. The internal coil is approximately 2-3 ohms.


This one ran for a good 15 mins before a re fill was needed.


It gets slightly warm but nothing to cause concern. And for the price I think it's great!
As I say I have a micro air pump to install but these cost a few pounds off eBay if you don't mind waiting for delivery from Hong kong, and they are tiny!


Ideas and thoughts ?

I am not sold on the E-cigarettes, or hooka pipes yet.
The exploding batteries shouldn't be an issue since you would be running off your ships main power.
There have been reports that some of the smoke fluids are high in formaldehyde.
And the fluids are designed to deliver nicotine,...
Hate to see someone over their boat huffing for a "nic fix". {-)

One of the guys on RCgroups asked about smoke options about the some time after you did.

And he has already taken the time to build up an oil burning unit.
Here's a link, Hopefully you will find some useful info there also.

Title: Re: DIY smoke generator
Post by: boman on June 21, 2015, 06:14:21 am
I made a smoke generator, that runs 6v. The body is a plastic case, with a too large Computer fan. Too large because the hole is around 6mm and the fan is 40mm.
It burns both baby oil and also smoke fluid. Element is from a hair dryer and the wick is a rag.

I posted a video on the face book page.

It produces quite a bit of smoke on baby oil, and a lesser smoke on the smoke fluid.

All I need to do is to figure out how to regulate the speed so as to generate a more realistic smoke.

 :-))  I use a Seuthe 6v smoker in my Glasgow Paddler. It is inserted in the smokestack about 2" down and does not deposit any oil on my deck at all. It gives a reasonable impression of smoke when sailing for about 15 mins.
Perhaps those who complain about this have the unit too close to the top of the funnel allowing the spitting oil to foul their decks?
