Art from scrap.

Small fans for fun

Caution.
The presentation is humorous


Okay !!!!
The title is a trap !!!!
So you will notice it and maybe say Bravo and have some applause. !!!

Applause. !!

The artist's bread. !!!

Now surely some of you will smile.

I'm not an artist. Sometimes I just like to make new things out of old and useless items. Give them a new life.

So I opened up this issue in order to introduce you to some small fans of useless materials and minimal expenses.



One day my sister decided to get rid of an old PC tower she had and gave me some accessories before throwing it into recycling. Eventually I kept 3 fans with the thought of making something.

So with some old pendulum gears, some plexiglass pieces, wooden handles from some barbecue iron forks, aluminum antenna TV tubes, a little 1.5mm thick steel wire, 2 metal fast connectors from p/c, one aluminium spinner from a r/c plane, half a kilo of black dust on hands and clothes from the boring and polishing of aluminum, 10 pounds of imagination and almost 2 weeks of work (1-2 hours a day). And of course coffee and cigarettes (free of charge).

The materials were unique so no mistake should be made. What bothered me was being able to center the gears on the 2 pieces of plexiglass since they didn't turn around with a half-millimeter gap. I did 3 tests until I finally did it, drilled and drilled again. So by turning the gear reducer this turns the larger gear and this in turn lowers or lifts the fan so we have an adjustable airflow angle (up or down). The pinion and plexiglass block rests on the 2 wooden bases and, of course, with the lever support of a wire rod. The 12 volt power supply is via the 2 wires that hold it in suspension.

Complicated but functional.

Didn't have a 12 volt power adapter, so I used an old phone charger.
But if some people love you then your life becomes more comfortable.

A friend built and sent me a power adapter - so now the little fan is ready.

Very nice. My brother goes to scrap years and finds metal to make welded art sculptures. I appreciate your creativity.

This is a piece we have on our back porch. A welder friend will just grab scrap from his pile of scrap from paying projects, and make something up. His only "rule" is not not use any metal that is not from his scrap pile.

This one has toes made of ball bearings, and a mud dauber started making a nest for a baby in one of the eyes. Now both eyes are closed up with mud. Since mud daubers gather up spiders to stuff into the nest, we leave em alone.

Then followed another similar construction to the second fan from the old P / C. Of course the materials were scarce and became almost like the first. And here the 12 volt power supply to the motor is via the 2 small steel wires that hold the fan in suspension.

The next construction presentation.

http://forums.pelicanparts.com/uploa...1572363905.jpg

Some time ago, one afternoon (as a susceptible citizen for the salvation of the planet), throwing some magazines and newspapers into the recycle bin I saw a broken plastic airplane toy thrown out of a bag. So I took out a four blade propeller and two engine lids (all of which were useless) in order to make a small fan for my computer desk, more like fun than functionality. Anyway with 5-10 euros I could have bought one ready from the Chinese but…. the point was to exercise the brain as well.
This is how the story of the desk fan begins.


Here are the first designs-adaptations-research. An old TRex 600 head bearing, an aluminum pipe piece from A/C car, a broken electric iron section, some TV antenna tubes, various screws, plexiglass pieces, a Weber carburetor float and lever assy, the two plastic engine caps, one electric motor 12v from an old car radio tape, a small rubber band and the propeller.

http://forums.pelicanparts.com/uploa...1572585152.jpg


The construction was fun but …… .it was just the beginning for it to evolve.
At some point I saw an ad about a damaged Nitro engine from an RC car. Then it came to my mind to review the whole design of the fan and make something different but out of scrap materials. Eventually the engine from the car was rejected as an option because the exhaust outlet was upside down, meaning it would look at the propeller. So I decided that the best solution would be to pick a plane engine and focus on research.

Advertise on aeromodellimg.gr (Greek forum) and the engine (a 40 MAGNUM GP) was found and bought at a symbolic price by a Greek air modeler Constantine, who along with the engine sent 2 propellers and 2 spinners. The modelers finally have a big and good heart. So the old bags were reopened and all the scrap aluminum I had left over from previous builds was re-assembled to begin the study, design and puzzle of future construction. The propeller rotation would give a 12 V motor from the car's kilometer dial gauge.

It was mounted in an aluminum cylinder parts by a brake master cylinder and with a simple rubber band moved the crankshaft and the propeller. As later, however, the tests showed that it did not have the proper strength and warmed up after 7-10 minutes.

http://forums.pelicanparts.com/uploa...1572585244.jpg


A change of design and an old videocassete recorder gave his motor (with enough torque and 2200 speeds/min) but due to its size it no longer fit the aluminum cylinder. Not to be outdone, an old useless electric petrol pump from Renault Twingo cannibalized. The cylindrical outer shell was cut, polished, and covered the 12v motor. The classic rubber band from the motor to the propeller, was now replaced by a red O-Ring.

http://forums.pelicanparts.com/uploa...1572585299.jpg

The support base of the whole construction was also a problem. I thought it would be great to have the whole machine, propeller and drivetrain (motor 12v) give the impression of being "in the air", so I cut some pieces of plexiglass to make an arm to screw the engine with its accessories. 4 aluminum plugs of unknown origin were employed to secure the plexiglass sections and 2 pieces of seat belt pretensioners for the so-called base legs. By this way I had now stabilized the whole set. The piston and cylinder sleeve were then removed to allow the crank to move freely.

What I had not calculated (ignorance from airplanes) is that the engine had no bearing on the crank so no continuous lubrication was required. Maybe in a second time I will make a conversion, mount (if I find it) bearings and remove the crank by replacing it with some 6mm long screw on which I will fasten the propeller. We'll see.

On the back plate I fastened and screwed an aluminum plate with a hole in the center, I put a 5mm long screw and passed with some spacers, an arm to hold the electric motor and a piece of plexiglass to support the ‘’ fuel tank’’. The engine was supposed to be powered by fuel. I could have put 2 silicone tubes and a plastic container and connected them to the engine and the exhaust but ……

This… but… is the headache because I had to find something that fits.

Two solid 6mm thick aluminum antenna TV tubes took the appropriate length and angles and connected the carburetor and the exhaust to the source from a car A / C pipe fittings along with a old WEBER carburetor float assy by Renault 5 Alpine and I had to change to 2 double 45 Weber.

http://forums.pelicanparts.com/uploa...1572585751.jpg


I thought that instead of having the 220 v-12v adapter constantly plugged in, even if the fan didn't work, camouflage it all over the frame (on an aluminum base) and turn it on when I want it with an On-Off switch, so with a 2 meter bipolar cable from the power outlet to the switch (and the adapter) would be better. From thought to application, however, there has been some time spent researching mainly on finding a new 1000 mA transformer-adapter (approx) but in small dimensions, something like a cell phone charger and from which I would just hold the board to better hide it. Internet research showed a cost of 3-4 euros and a local store 7 euros.


It was not the 7 euros but the behavior of the shop that prevented the purchase. Searching the warehouse again found a transformer (maybe from some old TV or video recorder, I don't remember) but it was AC and so with a rectifier bridge the current was converted to DC to work the motor. The good thing was also that the transformer had 3 cables output and 1 and 2 amp voltage so I added an ON-OFF-ON switch so that I could branch off to the motor and have 2 different rotational speeds. The test was successful and now I had to 'hide' the transformer beautifully. The old Pierburg petrol electric pump 72196004 from SLK provided a portion of its outer cylindrical aluminum housing and concealed the transformer and rectifier bridge along with a capacitor.

Many tests were carried out to enable the transformer group to find a point, visually satisfactory, where it would determine its final position. My idea came from a futuristic Honda project. So with 2 triangular bases of plexiglass and 2 springs to dampen any oscillation and resonance, it was positioned at the front bottom and behind the propeller. At this point it will also have a better ventilation-cooling and temperature elimination. Unnecessary details will tell but it does not matter. When you are making something you have to have the imagination, but with the danger of being labeled in the end and… imaginative.

And we got to the wiring and power supply. I installed 2 Aviation plug cable connector (here we smile) to quickly unplug the power cord on an aluminum plate, connect the cables to the adapter and the ON-OFF-ON switch.

Coming soon new photos with a 3 blades propeller.

Wonderful work! Like your craftsmanship and humor.

Love the idea of art and machinery together!

Folk art

Thanks Mr. Madcorgi. (very beautiful white 911 !!!!!!)

Thanks Mr. Asphaltgambler

Mr. Tabs I don't know if it's folk art, but for me it's an attempt to create something useful out of scrap materials. Trust me it's not easy to match between different materials. It's like the puzzle. And the result is joy.



And here are the photos with the 3 blades propeller.
Now it sends more air.

I love your art!

There is an electronics recycling place that would be a great source for you except it is 1/2 the world away.

Keep creating and posting.

^^^ Yeah....what he said!

Thanks Mr. LWJ.


I looked at the Google Map of where you live. It is a very beautiful place. I wish I lived there. I also saw the electronics recycling place at Tualatin (Google photos) but my designs are usually made of aluminum car parts, plexiglass and wood. Materials that have ended their lifecycle, that is, waste-dead. I try to match these materials together so that I can make something, that is, give them a new life again. And these constructions are unique because there are no secondary materials.

Here are some other older constructions.

Wonderful creations jean-zac, thank you for sharing.

Here's another construction.

The materials I had to build a new desk fan started to diminish. But everything had to be useless or used. Even a piece of wood that I used was from a broken bench. I found it thrown into a small forest where I was going to ride the bike.
Unfortunately I don't have many photos because the construction was for fun and not for projection.

The fan consists of the following objects.
-Air model nitro engine. Engine a Russian 6.5 cubic ( 40r), not RC carburetor but stunt. It is for control line aircraft. Gifted by an air modeler.

-Three blades pusher propeller 11 x 8 (11 inches in diameter or 28 cm) and a 'step' of 8 inches or about 20 cm. The propeller step is the distance that will be propelled if it makes a full turn under hypothetical conditions without taking into account the reduction in air distance due to opposing forces. A gift too.
-Electric motor 12 volt electric coming from a damaged hair dryer.
-Print head-heat sinks to support electric motor.
-Various A / C cars tubes and TV antennas.
-Plexiglas.
- Part of a rather American automatic gearbox.
(Temporary support base.}
- Screws different.

So the crankshaft-piston-crankshaft was removed and a bearing was added to make the propeller rotate better. The various aluminum parts added were to give some shape to the whole set. I have not yet found the support, as the rationale is to '' hover '' and for this reason I have placed the plexiglass between the fan and the base as a connection between the two parts using its relative transparency.
At the moment this is what it is, but some things will change along the way, mainly on the basis of support. Maybe I make it out of wood and with some springs or a counterweight I can change the fan angle.

In the 2 photos the little fan is with a Carmona bonsai that I make for my sister.

The truth is, I was not satisfied. The design was very simple. So I made the decision to start the fan again. I found a 3.2 mm steel wire and so I thought of making a wire arm that would keep the engine suspended. In theory it was easy but in practice I had to solve several issues such as power supply and the balance of construction. The air R / C engine was connected to the back plate with the A / C car tubes and the electric motor from the electric hair dryer. The whole connection, design and customization was not easy. The piece of wood from the bench became the new base and on the steel wires I made some corners to bring the construction to the proper height. At the engine mounting point with the 2 steel wires, I hid a clamp (for connecting electric wires) and there I connected the power supply cable to the 12v motor. To be able to keep the construction in balance because the base (the piece of wood) was small I thought of using a counterweight. This counterweight comes from a damaged printing machine I had found in 2002. It has now found a new place to offer its services again.

I used a mobile phone charger to power the construction and I connected it to the 2 steel wires to power the cable and the electric motor. I also put an On-Off switch in front of the charger and connected it to a 230v power outlet. So the charger is not a continuous current.


The presentation was made so that someone else could make something similar. It's great to share experiences.

I know !!!!! I do not speak very good your language and I have made many spelling and editorial mistakes. But I think you all understood how to connect and build.
