DIY Candle Powered Desk Fan! (using a strip of copper and a brick) tealight powered 3-speed easy DIY

- Опубликовано: 8 сен 2024
- DIY Candle Powered Fans! high airflow, quiet motors, 3 speeds. 1 to 3 tealights powers the fans (no other power source is needed). super easy to make; just place brick on the table, bend copper as shown, set copper on the brick, place fan on the copper. that's it. fan runs up to 5 hours using standard tealights and up to 7 hours using 'long burn' tealights. lots of details in the video including the build, bending the copper, temp testing the copper, close-ups of the fans (back and front), airflow (tinsel) tests, a side-by-side speed test (with 1, 2 and 3 tealights), day and night footage, how to run the fans using regular candles, a larger fan demo, and a talk-thru on how exactly the fans work.
Details on the Items:
The Fans: the fans are called "heat powered stove fans". amazon has them (probably over 100 different models). i use the ones with a temp range from 122F(50C) to 660F(350C). i also generally buy the ones with a low center of gravity.
The Copper: the copper is 24-gauge copper sheet metal. sold on amazon. it. will get anywhere from 300F/150C to 480F/249C (which is basically the perfect temp range for these fans). height of the stands... 1 1/8" and 1 3/4". and the width is 2"
The Bricks: the bricks are 2x4x8 inch flat stone bricks (found at the home stores; cost about 75 cents).
The Tealights: i usually buy them at walmart (50 for $3.87 or 100 for $4.97)
The Peltier Chip: the 'TEG chips' in the fans (the thermo-electric generator chips) are typically rated to last 100,000 hours, so for a very long time. they also sell replacement motors and chips if needed.
Great as usual. This settles some of my short term Summer power outage issues... How to keep cool at night. Of course you have given me Sooo many ideas over the years and I'm very greatful.
hi and thanks. yes this would be great when power goes put. you've got the fan plus the light it puts out.
Your videos and heater designs keep getting more impressive. Thank you for sharing this knowledge.
What square foot area would you estimate the two and three tea light heaters warming up ?
I seen your links on your channel and I have to say I really like instructables and seen you also had a Pinterest link. Thank you for sharing your videos
Have you considered 3" wide copper with 5 tealights staggered like the Olympic Rings 3 and 2? I think it would fit on the same brick or might need and oversize brick. It would be nice to see in future. Thanks...Good Job.
i thought of using a wider copper strip and more candles but there is really no need to do that. the fans run great on 2 or 3 candles. might be worth doing if you have one of the larger stove fans. i may make a jumbo version just to see how it works. maybe 6 candles and a 4" wide strip.
the future of energy generator is RIGHT HERE folks, keep exploring this idea brother.
you bet. i just started work on a video that uses a TEG chip (with a candle and copper) but no fan this time. i'm just using a regular heat sink. we should be able to take voltage and current reading from the chip. the power could then be used for lots of things. maybe even used to charge a battery or batteries. the title might be "how to charge a battery with a candle". that sounds cool.
This is totally awesome.
hi and thanks! 🙂👍
@@desertsun02 can you do something similar to generate electricity with fans or some kind of propeller for off grid power source.
yes, my next video is going to be using one of the thermo-electric chips along with some copper and a candle to generate electricity to run motors, lights, and charge batteries. instead of the body of the fan i'll be using a standard heatsink (so no propeller), it will just generate electricity from the candle. i started working on that video yesterday
@@desertsun02 looking forward to that.
i just re-read your comment and it looks like you were asking if i'm going to make a 'wind turbine like' device to generate electricity. i actually don't have any plans to build a wind turbine. the main reason is that i normally don't have much wind where i live (so it's hard to even test any invention that i work on).
Brilliant video
Hey,
Thank you for your videos.
I have a question.
Could you use a cerosin heater but replace the cerosin with oil and the wick woth carbon felt?
Would that work?
Greatings
Can we bring heat source closer to the TEG chip to get higher temp difference?
So is it a warm or cool breeze?
hi. neither really. it's mainly meant to be an air circulator. most of the time it just feels like it's blowing room temp air around (but occasionally picks up the heat from the candles). the average output of a tealight is 32 watts, (so 2=64w, 3=96w). A good way to look at it is to compare this candle powered fan with a standard AC powered box fan. those are roughly 30w/60w/90w for Low/Medium/High Speed and the candle powered fan is 32w/64w/96w for low/medium/high speed (using 1, 2 or 3 tealights). since it's the same wattages for either fan, the same amount of heat is generated. in general, this would mean that the candle powered fan heats the air about as much as running a box fan.
Another great vid love the ideas you explore v simple, v effective.
(sorry if I missed it, but is this just for air circulation, or do the fans blow out warm /hot air?)
Great, easy, and simple idea. Wondering if it would work with the candles UNDER a firebrick (or a similar heat sink), with the fan above the brick? As a heat source.
i think that would work but you'd have to wait a while for the heat to travel all the way through the brick and be hot enough for the fan to start. if you do it with just copper the copper gets hot almost instantly and the fan starts within about 1 minute.
I wonder how well this would work on top of a plant pot tea light heater to spread the rising warm air
hi. i've got a video or too on that. it works pretty good.
For a stove ecofan
Which computer fan ?
With magnetic Bearing (Corsair LM)
or double Béring with oil.
is it warm air or cool air ? how much do the dans cost ? can an alternative be used ?
hi. generally the air feels like room temperature air but occasionally the fans pick up the heat of the candles too. a lot depends on how close the fan is to the candles. the higher the stand the cooler the air. also, the taller the fan the cooler the air. the fans i used cost $15 and $20. the larger triangular shaped one was $29. personally, i like the smaller one with the 4 blades the best. that one was $15. you should be able to use almost any 'stove fan' that has a starting temp of 122F)50C). amazon sells lots of them
Good video thanks for sharing YAH bless !
@MrGeoRocks metal is more conductive that clay
Are those chips also called peltier devices?
hi yes.
Nice one! I use kinda the same technic, but I use an aluminium strip. Where can I find some copper strips? I live in the Netherlands
hi there. best place i know of to get the copper cheap is amazon. they sell it in different sizes or you can buy it in bulk *by the pound (that's what i do). the bulk pieces are usually about the right size.
so how to make the fan? title says make a Candle Powered Desk Fan?
i just updated it to "DIY Candle powered desk fan". might be better
You don't make the fan... you buy it. Those fans are expensive! Those fans are designed to work on wood burning stoves to circulate the heat produced by the stove. What he is doing is showing a substitute way for making the fan work without a wood burning stove.
@@desertsun02 I don't know the cost of the fans but you can buy the magic device that makes the power for good prices from far East factories/suppliers, then epoxy adhesive metal fins to the top cold side and add a toy car motor to it to spin a fan
@@j.l.emerson592 yes they are the companies selling them are really making a profit, the cost of the parts is the magic device at the bottom, some metal fins and an old toy car motor
the cost of the fans is really not much more than a regular table fan. the fan with the black blades was 15 dollars and the one with the silver blades was 19 dollars. a good AC powered desk fan is about the same price (so the cost is about the same as a regular fan). some are sold for much more but no need to pay the extra cost.
