Ultra-cheap smoker
« on: June 20, 2019, 05:48:32 PM »

I built this today from a bit of scrap plasticard, a dounhnut ultrasonic vaporiser and a minifan - all works off USB - total cost 2.50.
I'm quite pleased with the result...   :-))

Very nice,
Being somewhat dense when it comes to anything electricery, can you show us what and where things go to make one please, and where to buy the bits.
Yours runs off a USB, so is that 3 volts?.

Regards,

Len.

Also very interested especially looking for proportional control and mucky smoke( Diesel )

Cheers   links are for identical items but you need to look for the better prices.

I've got a parallel circuit in the boat that has a DC-DC converter that takes anything from 4-40v i/p and it has USB (5V) output with an LED voltmeter built in - 99p for 4.   This feeds a 4-way USB hub which powers everything. 
https://www.ebay.co.uk/itm/Blesiya-DC-DC-LED-On-board-Power-Supply-Power-Supply-Module-5V-USB-Charging/253586901913?hash=item3b0af50b99:g:dkAAAOSwHnJb5czr

The Vaporiser is a USB doughnut shaped one from Ebay China - less than 2  https://www.ebay.co.uk/itm/Donut-Shaped-Air-Purifier-Aroma-Diffuser-USB-Office-Desktop-Humidifier-NEW/183779383511?hash=item2aca1ad8d7:m:mPNQ3ywpjPnFxvm8lPxQmWw

The fan is a USB 40mm fan, again from China - 99p for 2.  https://www.ebay.co.uk/itm/Top-DC-5V-USB-power-4cm-40mm-40x40x10mm-4010S-Brushless-Cooling-cooler-Fan-New/273787707246?hash=item3fbf04df6e:g:b6kAAOSw0UdXtX5N&frcectupt=true

I've got a load of different batteries that fit in my boats with different voltages so everything is compatible with everything else.  USB powers all the extras like lights and the smoker.  https://www.ebay.co.uk/itm/USB-5V-2835-12SMD-20CM-RGB-LED-Strip-Light-Bar-TV-Back-Lighting-Kit/362422935885?hash=item546217214d:g:VfIAAOSwYlZbg~NZ&frcectupt=true

The standard voltage you can expect to find on the power lines of anything USB (those handy sockets that everything that plugs into your PC through these days) is 5 volts.  The various versions of USB (original USB, white plug tabs, USB2 black, USB3 blue) can supply different levels of current, but all at 5 volts.  Because terminating is a fiddly and error prone job, USB leads are best bought ready to use, the main problem is figuring out which actual plug you want on the ends of the wire.

That's the whole point - it all comes ready wired so no soldering or mucking about - it's modular so easy to build & fix.

Brilliant!  :-))

I notice that the smoke unit that you link is rated at 0.3W but that there is another (link below) that is rated at 2W & costs 1.89. Whether this means that it produces nearly 7 times as much smoke is open to wild speculation.

Do you have any thoughts on this?

How much water do they actually vaporize - how big a tank do you need?

Congrats plastic, simple and really effective. I've ordered 2 misters, one to use, and one to experiment with. I want to find out if the mister will handle 6 volts, and for how long.
 I presume you have a water reservoir in the bottom of yours, how much does it hold?

Anyone ever found a UK supplier for the ultrasonic units yet?  The small ones all seem to need importing.

For the tank, I placed a metal ruler on the edge of a sheet of plasticard and cut the width of the ruler - about 25mm - to create a tank with the least number of joints - rolled it like a tape measure and dropped it into boiling water to set the plastic into a uniform curve - glued the 2 end together and it ended up about 70mm diameter - then cut a top & bottom.   drilled a few holes for the fan, chimney & filling pipe and slapped it all together with liquid glue - no drawings - whole thing done in 30 mins.

Why run it on 6v?    The little DC-DC converters create 5v USB from any input - 4-40V for less than 1  saves cutting wires and messing about.

If it is USB, almost certainly not for long at all.  5 volt UBEC power supplies that are happy to run off 6 volts are available and cheap.

Any available here will have been imported, and will not benefit from the Chinese post subsidy and will have gained UK handling costs.

Tank is 70mm-ish by 25mm-ish - and I wouldn't trust any of the Chinese specs for current consumption - I'll bet they're all out of the same factory - remember the 320A ESCs?

Have you remembered that a 6v battery gives a lot more than 6v when fully charged?

A fully charged 6v lead acid gives around 6.37 volts

A fully charged 6v 5 cell NiMH pack gives a maximum of around 1.45v per 1.2v cell so say 7.25v.

I agree with Plastic that a Voltage UBEC controller is a good idea.

I have lots of different batteries, all different voltages so the USB psu standardises all that ancillaries to 5v

Plastic
I am very interested in you post as last week I also tried to convert one of these smokers for a boat.
I cut the wire and fitted a Futaba connector and used a 4.8v battery pack. The wire has a coating on it so after a bit of advice from David48 (
grip it between a sheet of fine abrasive paper and  pull  it one way only.) it soldered okay.
I have not yet packaged it but used a spray paint top as the water supply just to test it.

did it work ok?    I work on the theory that the big boat battery is my main power source so the DC-DC/USB converter sorts it out for the vaporiser and its fan.   The USB power supplies are so cheap that any other solution will cost you more money & hassle - like trying to solder nasty cheap Chinese wire.  ;)

It worked fine.
I bought 2 of these units to play with so I will have a go at your system which does look better.
