DIY $2 Woodstove Fan EASY 2 minutes 

mirinae you're right, it could work like that too. i am used the second heatsink to hold it all together. without the lower heatsink it would just be a stack of loose parts. plus i think my woodstove might just fry the TEC by melting the solder. ..

I am not sure what my motor was rated for, but it was very small in size. I couldn't find a motor in my computer that would work either, they were all too big. Ask your friends for old cd/radio players they can donate. Even post on your facebook looking for old stuff to use. Peltier placement is pretty independent, there is no hot/cold side.

My motor is 1.5V. A far cry from 12V

oh snap. so, these peltiers are rated at 12v but, that's input not output? do you know if they make other peltiers that produce more voltage than 1.5V?

They do make much larger ones but the price increase is steep. The output can be 12v but you would need enough current to make a difference. It seems likely that a motor from any cd player that can run on 2 AA batteries would work well

I experimented with the peltier plate you recommended. 1) it only produces 2V at MAX given a super heat source vs. a super cold source. i placed the peltier on my stove top and a steel cup of ice water on top. if you go above 250 degrees F it will melt the solder coming out of the peltier. so, with that said - max voltage is 2V using 200-250 degrees with a serious cooling system on your cooling sink. we're talking low temperatures for this whole system. otherwise, all these compenents melt down.

This is world new stove fan. Would you like to try? www.amazon.com/gp/product/B019DD3HO0/ref=s9_hps_bw_g201_i5

Pan Honge Please DO NOT place the fan in front of the chimney or near the chimney,the temperature around chimney pipe is very high,it may cause damage of your fan.The optimum position is at the side or back part of the stove top.

thanks for the info

what do you mean? Im just unsure about what you mean by a low-voltage induction heater fan for camping is all. Maybe provide the description without using the word induction please

Crystal graphite rod using electrical current to vibrate crystal graphite red hot. To produce a heater and a hot plate you can operate off solar.

Like how a high energy transmission coil heats metal atoms to produce heat on an induction cook top.

A man could use a low voltage hertz emitting diode to cause the Crystal graphite to resonate and turn red hot. Y'all know more about that kinda of stuff mate? Vibration technology?

I should have went to MIT then I would not know how this science works. ; )

Ava Maria when you put the woodstove fan on the woodstove, the heatsink in contact with the stove is exposed to heat. the heat is conducted up through the TEC into the upper heatsink where it is released into the air. the heat moving through the TEC produces an electric current, powering the fan

Does 2 heatsinks give more heat than just one? I only have one.

Ava Maria probably not, i actually think two would give you less heat. helping you to keep your tec from melting entirely

I hope I find another one soon. Can't wait to try my hands at making the fan.

Jod Bronson i got it at a computer shop recycled for free

I went to the computer shop and asked for the ones from their recycle bin. I got them for free.

yes

Also put them in parallel for more wattage

It helps a lot

Viper90087 the other parts are free from recycle bins. Go to a PC shop and they'll have loads of these parts

I got the heatsinks for free from a computer shop recycle bin. Thats how :)

rick pen great question! I only found that a motor as low as 1.5V would work. my motor came from a cd player powered by two AA batteries

thank you

At least one million volts.

i got the other parts for free, guy. its pretty easy to find a plant pot. easy to get a heat exchanger, just ask the guy at your local computer shop: they have a pile of them in the back room for recycling.

Why do you say that? I got that chip for $2, got the heat sinks for free?
