How to Make an Airsoft Mosfet

[@fastairsoft1797]

Hey man, I know you made this video 4 years ago but, it is never late to say THANK YOU. I made my own and works awesome! It been more then a year amd still going strong. Again, thank you for sharing

[@jyconmatocino3892]

hello. can this mosfet handle 170 to 210 hard spring? hope you will reply sir. 🙂

[@southwests5508]

Great video! But the diode just allows current to travel only one direction to avoid feed back. So I don't think its necessary. One other thinh is you should crush the wire before u solder it then screw it to allow for more coper to attach to the surface, or just solder the wire directly. I'm assuming ur using 60/40 and coper is much more conductive that solder is. Great design. I think I'm just gonna drop the diode and maybe do silver plated. Thanks!!!

[@sergiocarrero-ortiz5196]

How did it work so far? with out diode

[@alexcurmi7412]

Always use a diode when inductors and mosfets are linked. The inductance from the motor will kill the mosfet, I speak from experience

[@alphabravoas8768]

Where did I go wrong? I have expirience with soldering and electronics, I'm working at cellphone service, bought supplies and made few of these...some of them were faulty at the beginging, and some of them just didn't work well, as soon as I connect battery rifle start to shoot in full auto with selector in safe position. Yes, I checked diode polarity, and after this happening I used a multimeter to check it and it seems mosfets itself died...diode was ok, so as resistors. 2-3 of them worked for maybe 200 shots and then suddenly became melting hot and died... I'm out of supplies...any thoughts?

[@juanderful229]

How did it go? Did you manage to fix the design or figure out what was wrong?

[@alphabravoas8768]

@@juanderful229 no, since I couldn't figure out what was the problem. I didn't want to waste any more money on testing...

[@ilhamprakoso1237]

You need huge amps mosfet, and make sure it was original so it could hold a huge amps.

[@alphabravoas8768]

@@ilhamprakoso1237 maybe it was fake amp, since I bought it from aliexpress

[@BismillahBisasukses]

😄😄😄

[@TriggerFpv]

can you elaborate as to why your using such a large ziner diode and not just a regular diode?

[@rogerborg]

It's TVS, not Zener. And he doesn't know: the diode should be across the motor terminals, not the mosfet itself.

[@mr.airsoft8295]

​@@rogerborgCan you elaborate on this please? I'm Interested in knowing what the difference would be.

[@mangkepwengstudio3259]

i built one, and am using 11.1v lipo battery, on my experience, i feel like with just few clicks the battery and the motor is heating fast, what could be the problem?

[@dedeariandy299]

thank you for this awesome tutorial , but what happen if i use 1500 W 18A TVS diode ? it is still working properly ?? ..

[@fredrikhalasz4450]

Got a problem after a few shots in went all auto even if the trigger is relased ?

[@warlax5658]

Hey, I'm looking for kind of a cheeper MOSFET. It seems like most have weird programming capabilities; I just want one that switches off when my lipo is running low. I'm a bit new to airsoft and I was wondering if this particular assembly fit the bill. Thanks!

[@ExplosiveReview]

This has no low voltage cutoff but I just stop when my gun gets slugish. Haven't ruined a lipo yet.

[@dannyboy8231995]

+Daniel Warfield juts buy a lipo alarm while you are at it. they are like $3

[@oldc4838]

How about sir if my mosfet is IRLB4030 ? this fit?

[@MrHaidar13]

i use this mosfet with m140 spring 11.1v 30c baterai and m160 bigdragon motor mosfet fry just 30 second i use with full auto whats the problem ? the mosfet get to hot 6 times i try tu built it get same result mosfet fry

[@pmm4177]

Ever since I discovered flux I haven't soldered without it the past 4 years!

[@PlayTime-dk5jf]

I don't know what wrong with my mosfet. I just followed the video but it's breaked my mosfet not stopping to fire.

[@Recovery12Life]

man, I tried to make this with a mosfet and diode that I got from radio shack's parts drawers and it didn't work. I think the diode was way off it was a 6A 05 1411 and the mosfet was a IRF510. no dice. didn't work. I ordered the right parts online so I should be able to reproduce the results from the first one of these I made

[@dizzytricksta8451]

+Recovery12Life While technically feasable, the amount of capacitance you would have to add to the circuit would be huge, and the space it would take up would be totally impractical. If you want better response get a higher C Lipo as they have the ability to dump current more quickly.

[@Recovery12Life]

I have some radio shack 6-amp rectifier diodes axial mounted like yours with 400amp surge for 1/2 cycles 9vpk would this be ok to use for these mosfets?

[@ExplosiveReview]

I have no clue

[@Recovery12Life]

lol, it didn't work. I got the right stuff it just took some time for delivery. these things have been working great for me.

[@Airsofthelpvancouver1963]

Where abouts could I find more detailed information

[@jafarsidik180]

Very clear tutorial...! Is the active breaking mosfet is run? thx...

[@Recovery12Life]

Hello, I made this mosfet and it works very well. I did however have several issues when I installed it. the 16ga wire was to thick and I had to seriously modify my grip to get the motor to slide in and actually had to do several modifications to the rest of the gun to get the mosfet and wires to fit. I did exactly what you sad and it looked the same shape as yours but I had to grind the hole in the reciever as well as the buffer tube and the plate between. it was a but more than I had hoped for but it did work. how bad would it be to use 18ga in the future. I mean is it really going to have that much difference with motor performance?

[@ExplosiveReview]

18 is fine if you can't fit 16. It can be a bit tricky to get in there. If you are using 18 try and use high conductance wire to minimize heating and performance loss.

[@dannyboy8231995]

+Recovery12Life actually, 18 awg is no better than stock wire (18awg is stock wire, juts not chines stock wire) so your better bet it to use ecowire 16 awg

[@orcgrunt50]

have question regarding the mosfet as far as the gate, and the switch poles, are these designated by the wiring or does the fet say on it which is which, as you can tell not much of an electrical person so just want to make sure

[@ExplosiveReview]

Barry Rigler Provided its a 3034 you need to build it exactly as shown. You cant switch the sides anything is on as far as I know.

[@orcgrunt50]

thanks i got the idea now , great instructions and well layed out. at this time i dont need a fancy computerized one just something simple to protect my batteries and motor . again thanks

[@memeleaca]

Dude, where or how put the + and the - of components together?

[@MrSponjaBob]

What is the difference between using the internal diode of the transistor to the new one as used here? Moreover, I am making a simple assembly with two transistors IRF1404 to divide the intensity and remove some heating. Am I doing it right? What mounting advise me for marui EG700 engine? Thank you very much and kind regards from Spain

[@hawkeye3157]

The internal diode of the transistor is a piece of shit. The diode used in this tutorial can actually take the voltage spikes from normal battery use. If you use two transistors, just be sure you get them in parallel with the same gate control and polarity. Sorry, I have never used that engine. Hope it helps!

[@gustavosouza351]

hello, I'm fron Brazil, installed the mosfet in my aeg but it is discharging the battery very fast, I did a test of 20 minutes firing intermittently the battery of 7.4 discharged to the point of no longer functioning aeg, has anyone ever encountered this problem?

[@tomdenooijer5851]

Hey very detailed review, helped me alot. Got a question though. Would it be possible to add a capacitor into the equation? So that whenever you lightly press the trigger, the cycle actually finishes instead of cutting out half way through , resulting in no shot.

[@orcgrunt50]

in regards to the diode i noticed that it has a gray band around one end , does it matter which way that the banded end faces ??

[@ExplosiveReview]

It does matter. The band must face the screw hole as you see in the video.

[@orcgrunt50]

thanks , not very tech savy , great video very informative , did put first one on backwards lol but all good , its a learning thing again thanks

[@elioliver9554]

can you link me the parts I'd need to do this same thing but with a little more strength, I want to use two 7.4 2500 mAh 25c lipos wired in parallel, or are these parts enough to withstand that

[@asmodeuszv]

any idea how to add precock and other stuff to it?

[@RiverFlow22]

Fantastic! So does a MOSFET replace the trigger trolley in an m4?

[@lennyswagmaster6567]

Yes a mosfet like an BTC Chimera, a BTC Spectre, or an AWS raptor fet will replace the triggrr assembly but as for standard mosfets they will not

[@AlMaledet]

Why the trigger cable to the battery has to be as closer as possible?

[@ExplosiveReview]

you can really put it anywhere along the positive wire. There is a design where you connect the wire directly to the contact but I can't make it work with the 16 AWG.

[@mr.airsoft8295]

Does anybody know how much amperage these things can handle?

[@Silverblade416]

Is it possible to make the mosfet plug-and-play style??

[@davidvalentino8811]

yah 500$ aeg

[@Krzeszny95]

There are those things called *connectors*. You use them.

[@ViniciusSales1991]

I need a mosfet for AEG 7.4V LIPO BATTERY AND 11.4V LIPO BATTERY, is the same ? the components dont need to change?

[@johnaccer4855]

+Vinicius Sales mosfet is the same for both.

[@RichardAugust1993]

Hello! What wire type should I use when making Mosfets? Solid Wire Hook-up Wire Teflon coated mil-spec wire Silicone wire Do i realy need the mini cooler? -Richard

[@ExplosiveReview]

Opinions differ greatly on this matter but I personally like 16 AWG stranded (not solid core) copper wire you can get at home depot or the like. Silicone wire has superior conductance but it is fragile and prone to damage. You don't need the heat sink but I like to add it as an extra layer of protection. LMK if you have any more questions.

[@tagurumoy1101]

Can I use irfz44n MOSFET?

[@johansnyman621]

Also want to know that...

[@orcgrunt50]

do have 1 more question , in regards to the wire do you recommend any preference in size. ie I am using 18 gauge on the thick wire , what size do you recommend for the thin wire , is 22 gauge good enough or is it smaller still

[@ExplosiveReview]

I use 16 awg if I can fit it and 22 for the leads.

[@MrBeny127]

😒😔I'm so pissed right now because I did EVERYTHING and got every part needed. I REWIRED THE MOSFET 4 TIMES. Still no dice. Maybe the terminal connector I'm using to screw onto the top is faulty? Maybe the resisters because I went through five of each are faulty? I mean it worked one time and I honestly don't know how it did. I pressed on the 100ohm resistor and it worked?? I have no idea. I'm just so pissed because I was so excited to built a MOSFET so I could finally use my custom built gearbox.

[@dannyboy8231995]

+MrBeny127 Have you tried pressing the trigger contacts closer together? I thought I fucked up mine the first time too but turn out i just needed to get the trigger contacts closer

[@MrBeny127]

Dannyboy823 yeah. I just remade it. after I put my gearbox together after a long day of getting fired at my job, my mosfet didn't fit it. I was literally about to kill myself lmao. ill just pay stinger to do it. and for him to do a complete tech up. like shimming, aoe, etc

[@MRboomMAN56]

Stinger that plays at futureball?!?!

[@MrBeny127]

boom_man56 idk. btw i fixed my build. nice 40 rps now lol

[@MRboomMAN56]

MrBeny127 nice

[@axeljimenez123]

I made one like yours but now when I press the trigger in semi it goes automatic. ....any idea why? please advise. ....I have a game next Saturday!

[@untrust2033]

Check your cutoff lever and clean your trigger contacts

[@mcguyver16able]

Can you explain why you use a diode in your design?

[@ExplosiveReview]

Well I'm no electrical engineer but from what I understand it acts as an overload protector for the more delicate components of the chip. Honestly you could probably use a smaller diode but this works for me and they seem to last awesome.

[@BIGH1001]

ExplosiveReview diodes are like a one way valve. and i'm certain you could've gotten away with something not so thumpin' big. but it's probably best you used that one.

[@christianjimerson4129]

What is the "stand" holding the mosfet?

[@christianjimerson4129]

***** Thanks man

[@organikness]

What parameters must be satisfied regarding the mosfet, or do you need that exact item (IRLB3034PBF) Cheers

[@halfcockedairsoft1403]

Do you the Volt and Amp limits of this device?

[@ExplosiveReview]

I do not but I have heard of people using 14v city this design on crazy high speed builds

[@halfcockedairsoft1403]

Ok, that's more than enough proof for me. Thanks for making this video, I'll be making a few of these with a slightly modified design.

[@ExplosiveReview]

Ya its a tried and true design. I would love to know how they turn out!

[@headshotairsofter7117]

hi can you make them plug and play

[@ExplosiveReview]

I have thought about this and I don't believe so. To have plug and play it requires a much more advanced computerized circuit. I still like the direct wired version better as I believe it delivers better electrical conductivity.

[@paulobriffikado1704]

There´s a guy in Brazil selling a parts kit for this mosfet and sending your video as a tutorial. He´s basically getting money from your video. Did you authorize him do to so?

[@ExplosiveReview]

I certainly did not but I in no way own this design. My video is free on the internet so he is welcome to send people to my channel as long as he has not stolen and reposted my video.

[@devious762]

Kelley Richards he’s getting his money from selling the kits not from the video...

[@YuriyDtv]

thank you

[@RichardAugust1993]

Fantastic! Thanks!

[@ExplosiveReview]

no problem. Keep an eye out for the installation guide

[@carlosfischer4705]

sorry but could not use a bulb reactor diode ho

[@patticromer9369]

OK he is building this correctly but the parts in the link are faulty so don't buy what he says, unless you know something idk.

[@ExplosiveReview]

Faulty how?
