Homemade Bladeless Fan (Ion Wind)

[ella5024]

Does it produce negative ions? I am looking for something to massively produce negative ions to surround my whole house.

[afdhalatifftan92]

@ella5024

I bet it does, but I can't estimate how 'massive' it is...

[james1574961137]

Can i use this technology to replace my actual fan or is it not as efficient or safe? 

[afdhalatifftan92]

@james1574961137

Sorry for the late reply. :)

I'm afraid the system is not efficient enough to replace conventional fan.

It might be some flaw in the circuit design, but hey, why not give it a try?

:)

[HorizonDelta]

Kool !

[afdhalatifftan92]

@HorizonDelta

Thanks! :)

[MtDeathShadow]

have you tryed useing this set up in a vacume? if it works there, than you just make a space ion drive :D

[ibm5150]

Put this underwater to propel a boat, Red October's silent drive!

[afdhalatifftan92]

@ibm5150

Someone done this before: /watch?v=TmOqbiybfzY

I believe it's quite inefficient...

:)

[paule1333]

"I will improve it soon...." :)

I know it.

[afdhalatifftan92]

@paule1333

Lol! :D

[snowman78619]

great work! do yo have a DIY write up for this? would like to try something similar if possible

[afdhalatifftan92]

@snowman78619

Thanks!

I'll try my best, to get the writeup done...

[afdhalatifftan92]

Yeah, lol! It's salvaged from old tv PCB...

[myryonspoof]

that's a big heasink.

[iMayfire]

Something Jig Saw would use.

[afdhalatifftan92]

@iMayfire

Jig Saw from the movie? Lol!

[iMayfire]

@afdhalatifftan92 yeah it looks evil lol.

[DireWolfessV]

I love these kind of videos for two reasons. First the end result is kinda cool. Second the show off. To some one who's not tech savvy like myself here's what i see "Hey look i took a SHIT ton of wires and strung them all over my garage" or. "Look how hard i try not to get laid." any way thumbs up if you agree

[afdhalatifftan92]

@DireWolfessV

Wow, thanks!

[BOERUSGENIUS]

you know ? if there are spark ,is generating ozone , that no good for healt,

and you must insert an hight voltage diode, to give negative current in the needle

you can use diode from old tv in black and white

ive got a little dezac dp240 pyramid shaped ionizer but i wanted one more powerfull.can it be bumped up tweeked or whatever,u can tell i dont know much about these but in 80's i used to have an amcor one and it was so powerfull pot plants would lean towards it and as they got close sparks would occur jumping to the leaves,what can i do? 

[afdhalatifftan92]

@2112cygnus1

Hi,

well, after Google'd your Dezac DP240,

I believe there's no easy way to mod it...

You will need to mod the PSU and emitter...

[hyphens]

pretty inefficient tho

[NOBOX7]

would A good static generater be able to produce this effect , what if a high altitude ballon had a 20 mile tether conducter could it propel itself by using lightning or potential differans of lower levels form the cloads

[afdhalatifftan92]

@NOBOX7

Whoa, that's a hard one! Lol!

Well, IDK,but, I guess any static generator with constant voltage could do this...

About the balloon, it's far from my knowledge to answer it...

[jiincredible]

Your work is awesome, I have the same problem with the output thingy, what values of capacitors and resistors did you used?

[maikukun1]

wow!

hey sir! did you use external primary for the ion wind emitter??

am just confused coz mine's quite not properly working, ..

PLEASE HELP..

[afdhalatifftan92]

@maikukun1

Lol!

Yup, I use external primary for the flyback...

What did you mean yours doesn't work properly?

The output is low?

[maikukun1]

@afdhalatifftan92

yeah..the output is quite low..I need to boost it..but I don't know wat's the ryt thing to do..

[afdhalatifftan92]

@maikukun1

Did you get the polarity inverted? I mean, in my experience, negative must be the emitter and positive is the collector. If it's alright, then you need to upgrade whether your flyback, or your driver circuit.

What's the circuit did you use? 555 or 494 or zvs?

[maikukun1]

@afdhalatifftan92

555 

[afdhalatifftan92]

@afdhalatifftan92

Is your flyback outputs ac or dc?

What's the mosfet you use? Does it gets hot?

Did you use any mosfet driver, like the tc4420?

Or, maybe you need to external primary as mine...

Have you tried swapping the primaries polarity?

What's your longest arc output?

Lol! Too much questions...

:-)

[maikukun1]

@afdhalatifftan92

flyback output is DC

YES, the mosfets gets hot..

sir..by the way.. what are value of capacitors and resistors did you use??

[afdhalatifftan92]

@maikukun1

Values? Did you meant the RC for the 555 timing?

I use 0.01uf and 10kohm pots...

Don't use any resistor at the gate of the mosfet, it will get hot easily...

Connect the output pin of 555 directly to the gate...

[maikukun1]

@afdhalatifftan92

flyback output is DC

YES, the mosfets gets hot..

sir..by the way.. what are values of capacitors and resistors did you use??

[yanlapanic]

WTF :D never saw that before , I dont ever understand why there is air flow but this is really cool man !

[looksintolasers]

What if you take away the anode plate, do you still get a signifigant airflow from the cathode tip?

[looksintolasers]

@looksintolasers Also, is this a dumb question??

[afdhalatifftan92]

@looksintolasers

That's a good question! Well, in my experience, the distance of the anode need to be tuned to get the best output. Booth too close and too far have its own characteristic.

Too close will develop corona discharge, making more ozone and throttling the output.

Too far will cause my flyback-transformer to arcs all over the place. Also, limiting the output.

If the distance varied slowly, then yes, increasing the length would resulting decreased output.

:-)

[sheskillingme]

cool!

what's the Mosfet that you used?

can you send me the schematic?

[afdhalatifftan92]

@sheskillingme

Lol! Thanks!

Actually, I'm using IGBT in the vid...

As for the Mosfet, I suggest you to use IRFP250, with TC4420 driver.

You could use 555-astable, but, I prefer TL494.

Google for "smbaker plasma" on the net for the circuit...

Thanks again!

[sheskillingme]

@afdhalatifftan92

ok..thanks..

[sheskillingme]

@afdhalatifftan92

what IGBT did you use!?does the strength of the emission of the ion wind

depend on the power transistor that you use!?

and @ what frequency do you work on!?

thanks!

[afdhalatifftan92]

@sheskillingme

Lol! Calm down!

Well, Idk, but, imho, no, the strength doesn't really related to the type of transistor I use. I use IGBT at that time because I'm run out of Mosfet.

I suggest you to use IRFP250 because it have lower Rdson and higher breakdown voltage. Thus, reducing the potential waste-heat produced.

I once used IRFZ44N, cause I thought the higher the rated amps, the cooler it will runs. Turns out it's a mistake.

To avoid the Mosfet from frying, I need a Mosfet Driver. :D

[afdhalatifftan92]

@sheskillingme

About the frequency, I think it really depends on your transformer specs.

In the video, I believe it running at about 27kHz. I could be wrong though. But, according to my experience, I don't really care the running frequency. I just build the circuit and tune it slowly until I reach the best output.

Also, don't forget to add the resonant cap. It somehow greatly improve my driver's efficiency.

Soon after you're done, post the vid and let me know!

:-)

[sheskillingme]

@afdhalatifftan92

ok..

thank u so much..

:')

[afdhalatifftan92]

@sheskillingme

Lol! No problem!

[ramicaza]

thats so cool!

[afdhalatifftan92]

@ramicaza

Thanks!

[PandionStudios]

Look at Geoff Hattons UAV saucer, its basical a radial wing, more stable than a helicopter, same princials as both a helicopter and a wing. You can do it with ionised air by using magnetic fields instead of solid geometry. Also you have more freedom to manipulate it in any way you want. Imaging being able to morph a plane wing instantaniously, or swap the direction that rotor blades go instantaneously.

[afdhalatifftan92]

@PandionStudios

Whoa, thanks for the info!

I just learnt something new, Coanda effect!

[PandionStudios]

@afdhalatifftan92

Hey, no problem! In the UAV video if you saw it, you don't need the actual dome shape, you create that with the toroid coil, the ions flow over the top and actually get accelerated round because of it. just need the ions to shoot to the absolute perimeter of the disk, do this by keeping the field gradients of the electrode in mind, sharp=high etc. Theres a video of an MHD boat, which shows you, just search for MHD boat on youtube. waters great to test these principals out in.

[PandionStudios]

@PandionStudios

The toroid coil creates the geometry, but via the magnetic field. Also you can alternate the direction to get more torque, and alsooo, aswell has having a centrifugal vortex over the top to the sharp edge of the negative disk, you could ionise the air with the same sharp edge, and have a coil on the bottom of the disk, and an smooth low gradient electrode to create a centripetal (think twister) underneath the craft.

[afdhalatifftan92]

@PandionStudios

It's kinda hard to imagine the construction via your post...

Could you link some pictures? Lol!

Yup, the MHD boat was way too cool!

Wanna play with it, but, I have no powerful magnets...

:-(

Thanks again!

[PandionStudios]

Pretty simple - ion lifters are rubbish because they don't cause a vacum over the top of any geometry meaning no pressure on the bottom like a wing. Also the ion wind is linear flow. Where as this, im guessing is more of a vortex. Look at flemings left hand ruel, top electrode is like this, radial electrode below (disk) torid coil in the middle, its basic Magnetohydrodynamics. You will cause ioned air to centrifugally cortex over the top of a disk, cause thrust aswell as suction like a wing

[PandionStudios]

Thats essentially how flying saucers work

[afdhalatifftan92]

@PandionStudios

Hard to say... It could be though...

[encefalitas]

NASA has the motor that operates on the same principle and can be used as fuel for almost everything.

[afdhalatifftan92]

@encefalitas

Thanks for the comment...

Well, maybe NASA right, but, where does they get the electricity?

[vox1philippines]

ok sir, thankz.....

pls watch my friend videos Ian 2bigHybrid, he is in HV consentration for his car......

thnkz

[vox1philippines]

pls be careful using as ionaser or ozonizer in your room, open all doors put the aparato in the center and leaved for 1 hour, use also electric fun to spread the ozone, generate ozone very well so that it will not harm our health. ...

can you share with us how did you Do it?

THANKZ.....

i'm using old model cellphone NOKIA N95....

VOX

[afdhalatifftan92]

@vox1philippines

Thanks for the kind advice... I really appreciate it...

The volume of ozone production is easily adjustable, by varying the duty-cycle.

Yup, I also use electric fan in my bed room.

The construction details is available on my blog.

Thanks again!

[vox1philippines]

afdhalatifftan92

Its nice to have one !!! its COOOOL but we're playing with a HV here hehehe....pls extra carefull.

what can i see here is you can make for us an OZONIZER.... to Clean our Drinking water, friuts, vagetables, and to have a fresh air in our rooms and to cure some bacterial problem in our body.

its almost same principle HV is use.... just refine friend for each purpose.....

thankz for sharing.....

vox

[afdhalatifftan92]

@vox1philippines

Whoa, thanks for the nice comment!

You're right, it does produce pleasant smell while its operate.

Makes me fresher each time I wake from bed!

Thanks again mate!

[CalabreseMPC]

you're a mad scientist :D

[afdhalatifftan92]

@CalabreseMPC

Lol! Thanks!!

[hbenders3356]

heh, probably not so effective as a spark gap quencher.

[afdhalatifftan92]

@hbenders3356 What's that?

[migiola]

very nice, mabe we will power some fly crafts someday with that

[afdhalatifftan92]

@migiola

Thanks for the kind comment!
