How to make an upcycled stove top fan (like an EcoFan), from an old chainsaw cylinder and a few other scrap bits. It's been done with CPU coolers, but I wanted to make more of a sculpture that circulated hot air from the wood burner around the workshop. In this video tutorial, I show you how to make your own.

Some of the parts I used:
Peltier or TEG - make sure it is rated to at least 150 degrees C - If you have the patience you can get a bunch very cheap on ebay here: ebay.us/VFWibP . These are all really TECs run in reverse, although not described as such. If you can, consider getting one that has a t-max of 250C - it will last better.
Motor is 1.5 - 6 v DC, easy to salvage from old cd or dvd players or available on e-bay: goo.gl/mTHpQf
I got the fan blades from e-bay: ebay.to/36s2i4H for about $8
The 3 blade one in the vid was an official Caframo ecofan replacement fan blade, which was more like $20 each (but these are harder to find).
You can also make your own fan blades - I show you how in this video: • How to make DIY Stove ...

Friends, thanks for watching! Check out my new stove fan innovation - a mechanical overheating protection, that keeps the TEG safe: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ipm77mhiwSg.html

I just bought a wood stove fan for my parents for Christmas and I'm amazed by it. The only reason I watched this video is because of it. But do it all your hard work and the s*** you did to make this video All right well I'm subscribed you win, And hopefully you've got a lot more awesome videos like this because that would be great!!!! Either way I'm still subscribed hopefully it'll bring some money to ya......

LOL thanks ga, and welcome aboard! Yeah check out some more of my recent vids and let me know what you think. Peace, Bongo.

@АлександрМ-н3ф Год назад

Спасибо за ваше видео и ценные идеи. Особенно понравился ваш эффективный тепловой редуктор. С ним можно не опасаться повреждения TEG от случайного перегрева на раскалившейся плите. Не думал. что такого TEG , будет достаточно для моторчика от CD с пропеллером. Спасибо вам !

@jons6368 4 года назад

Nice build. I have made one from a piece of aluminum I beam and a CPU heat sink. It's run for a few years now, but now I have developed a problem. I use two peliers wired in series, and I just put two new ones in it, it ran for several days and stopped. I changed out the motor as well. Which peliers do you buy for your build? I think this could be the problem. Thanks, great video!

@FloweringElbow 4 года назад

Good afternoon Jon, Thanks for the comment friend,and sorry for the late reply. To be honest it was quite a long time ago when I bought the peltiers, and now I cant find the supplier, or even the same ones again... Did you source some and get it working in the end? Have you seen the more recent video on this subject, where I add overheat protection? Thanks again, Bongo.

@abrahamf63 2 года назад

@matthewmilam286 6 лет назад

I really liked your idea I was going to make one myself But apparently the UK eBay is the only Place to find a fan blade the United States version of eBay does not have one I looked for about two hours and ordering a three pack From the UK Was going to be insanely expensive I guess here in the states they don’t want us making our own stove fans lol Guess I’ll be visiting the scrapyards trying to salvage some parts I will probably just have to make a fan blade

@FloweringElbow 6 лет назад

Great video with nice illustrations. The horror movie soundtrack was a little disconcerting though :) Actually the music is rather loud and distracting, and completely unnecessary in my opinion. Not a complaint, but I think viewers would get more value from this great video if there were no or much quieter music.

What about separating the components? Like the peltier can sit where it functions best and the fan where it can best move air?

@kevint1910 6 лет назад

it is called a "thermocouple"

@doctorwork 6 лет назад

What is called a thermocouple? The TEG? Not really. Granted, it works on the same principle as a TEG (the thermoelectric effect), but it is very different from one in practice. The term "thermocouple" is usually applied to a pair of wires made of dissimilar metals (like chromel and alumel) that are melted or welded together, and they produce a voltage proportional to temperature which a calibrated meter can read and display as a temperature. They aren't made to generate usable current. In contrast, a TEG like this one that is used near room temperature is made up of two layers of bismuth telluride, one of which is doped positively and one that is doped negatively. Unlike a thermocouple, which puts out almost no current and can not do any useful work, a TEG puts out a lot of current which is dependent on the area of the plate and the temperature gradient.

@kevint1910 6 лет назад

reread your post the two things your describing BOTH work off of the EXACT SAME QUANTUM EFFECT no matter what you call it Mr intellectualized idiot and THAT was my ONLY point. that said it is nice to see you know so many 5$ words and can even string them in to a readable sentence ...even if it is a pedantic nitpicking waste of punctuation.

@RPRosen-ki2fk 6 лет назад

Doc Work I work with thermocouples and RTD's everyday, but I've never seen a TEG before. Thanks for the explanation. It was clear, and very easy to understand.
