Airsoft Tutorials - DIY Mosfet

[@SethWilcox82]

Just set up my first MOSFET, works great, had to substitute the 3034 FET for a 2395, the electronics store I went to didn't even have a 3034 in their giant book. The 2395 is rated at 50 amps max, and 150 watt, and has only .028 ohms resistance. Not using a LiPo, yet, but trigger response has improved, as has the rate of fire. The most expensive thing I had to buy was the Helping Hands, that was around $30, even with my military discount! Can't wait to play with this FET this weekend.

[@AirsoftingTutorials]

I regularly use the mosfet with a big 11.1v and have also tested them up to 22.2v, not for very long though. As long as your setups good and the mosfet is well made you should not have any problems.

[@g_glop]

Problems with this tutorial: the drain pin is there for a reason. Don't say "but you could fry the mosfet", you already soldered to 2 other connections that are *more likley* to fry it because they are connected directly to the silicon. And also, the hole is for mounting the heatsink. 'Proceeds to put heatshrink over it.' I'm out! You're supposed to mount it to the gun's casing and use that as a heatsink! But now that you used the screwhole to attach the drain wire...

[@hakont.4960]

Mosfets in AEG don't need much cooling because the motor typically runs for a few seconds at most, and most AEG's pull way less current than what the mosfet chip is designed for. The wires will pull out enough heat to give sufficient cooling in AEG's, even my most upgraded AEG's barely heat up a 3034 mosfet. You're right about the soldering though, that's why I'm always very careful when soldering on mosfets. I don't use the screw method of attaching the drain wire anymore, I just solder it to the heatsink or drain pin, it won't cause any damage if you're careful.

[@g_glop]

***** I was a little bit too angry at the time of writing that comment. There isn't enough current to heat up the mosfet. Btw, for extra protection: when soldering you can grip the leads as they're coming out of the mosfet with tweezers/pliers so the heat from soldering goes to them rather than the silicon.

[@hakont.4960]

I have moments like that too, we're only human you know. I gently clamp the mosfet in a small vise so that it draws heat from the heat sink.

[@AirsoftingTutorials]

Held up fine in all of my rifles so far, increase in trigger response and rate of fire. Thanks AT

[@fedarin]

Hey would know about the mosfet specifications please, i went to eletric store and there are to many kinds, considering my battery is 11.1v lipo, motor g&p m130 hightorque, 7.2v~12v nominal 9.6v. Or just send me your specs of the mosfet thanks. There r a number in mosfet. Thanks

[@eatmydust1716]

can you show a tutorial on how to install the mosfet?

[@JuanRamosB]

I love this kind of work. Is always easier when you have the right tools. For me, I choose to buy one, but I would follow your tutorial if I've had the tools. You deserve more likes!

[@rogeliotamala5302]

Hi, I just want to ask where to connect the ends of twisted wires' tnx.

[@PlayTime-dk5jf]

It's okay without diode sir?

[@pesoen]

the heat sink, seems kinda pointless, when you are encasing the entire mosfet in heat shrink tubing, without cutting holes, for the hot air to escape, i know its optional, but still.

[@m4k850]

Hi i have only this two mosfets which is better ? Mosfet N-Channel 500V 14A - IRFP450PBF / Mosfet N-Channel 100V 33A - IRF540N

[@SethWilcox82]

Would it be any different making a MOSFET for something with a v6 gearbox, like a P90?

[@nitemunky76]

No. No difference.

[@stefanallman7774]

Would putting a auto resetting fuse in the circuit somewhere, say between the battery and motor affect this? No, right? And the purpose of the resistor around the two pins is to complete the circuit from the smaller black wire without shorting out the battery. It does that by putting a load, or resistance, right?

[@ENTRENCHING]

awesome ! is there a video of the AEG shooting with and without ? great work creating all these video's !

[@grahamwilliams2494]

I got my mosfet all wired up. I checked it using an electric meter. When I plugged my 11.1v lipo in, I heard a short "hiss" and it did not work. Is it possible that my battery is too strong or that maybe I need to just replace the resistors or the mosfet? My battery is a 11.1v 2200mAh lipo. Please help!

[@CWBchannel]

How well has it held up? Did it show an increase in performance?

[@frantisekskudrna9232]

Hi, Which wire gauge did you use ? (for signal and for motor) thx

[@Jvha761]

František Škudrna For signalwire use as thin as you can get and usually people use 16 or 18 awg wires as normal wires.

[@DommageCollateral]

what kind of mosfet is this?

[@LordKaos666]

Hi people...what about the diode that somebody add to the circuit? Thanks

[@hakont.4960]

It gives extra protection to the mosfet chip, but you can make the unit without it. The 3034 chip commonly used in AEG's have a built-in TVS diode, so it does have voltage spike protection. This diode isn't very strong though, so there is a small chance of frying the fet without an external diode.

[@kasztan2126]

is this completely safe for SA-H03 with Li-Po 11?

[@ZaCkOX900]

How many of these have you made before?

[@xXGinjaNinja72Xx]

Do you not need to heat sync the MOSFET when soldering

[@UTDHKRF90]

Still will be very greatfull if u could make a tutorial on how to install it.i scare i ruin my aeg later.already build it now waiting for u to make a tutorial on how to install it.thx hope u can help.tis sunday got a big game so i really hope can get it done tis week.thx.

[@aljhonbryansabater1579]

May i know the code of the mosfet? Thanks

[@rolandogonzaga4850]

What mosfet number didto use sir?

[@hawkeye3157]

You will want to put a TVS diode on it to protect against voltage spikes. Otherwise it is too easy to accidentally fry the mosfet.

[@benjaminbarr8714]

mosfets are great and all but I can't help but think there is like 5 different ways you can avoid the relay switch without a mosfet

[@TheErykjan]

what model of mosfet been use for this circuit ?

[@UTDHKRF90]

Hai nid help urgent pls.im using a 11.1v 25~35c discharge,so can i use exactly the same part in tis video or nid to change some part?pls help thx.

[@Skribuliss]

Is this mosfet whit AB?

[@AirsoftingTutorials]

To be honest I have no idea. The 3034 is the recommended one and is used by many, id check the spec sheets and compare but other from that i do not know.

[@jyconmatocino3892]

hello. does this mosfet able to handle a m170 spring to m210? hope you'll notice me.

[@jyconmatocino3892]

@Uvu Santos hello sir. Yes po pinoy.. 😊 pwede ko ma hingi FB mo sir. So that i can add you po.

[@lloyd2683]

Circuit diagram available??

[@UTDHKRF90]

And can u do a tutorial,on how to install tis mosfet to aeg?thx.

[@Boricua96792]

Can I have a list of everything needed please.

[@fedarin]

Man, you are fucking good, thanks a lot to share your knowledge with others, i i already watched all of ur vids, and waiting for more, unfortunately we dont have or its hard to find some airsoft peaces peaces in brazil, takes a long time to order and receive by mail. Wich is this lil peace that u showed in the begining? Could u make a video with a eletric trigger and something to get better a standard trigger? Thanks you a lot again. I will do a lot of things you teached here this weekend.

[@fedarin]

i have this one? is it a shit? or it works? considering low budged! www.ebairsoft.com/wiring-switch-mosfet-assembly-back-p-6478.html

[@ljudevitbinder9114]

Wow.this is great. Wish I had the knowledge...

[@AirsoftingTutorials]

I may do, basically you solder the two thin (twisted) wires to the the trigger block and thats it.

[@HaikIHeaD]

can I use this mosfets ?? IRFP450 or IRF540 ?

[@Thomas-rc9sc]

It depends on what voltage/current they can take. If you are using 11.1v (3s) then it needs to be at least that voltage and be able to cope with 200 amps

[@SnowNTA]

Amazing video bud. keep it up

[@ZaCkOX900]

I just thought you have done this a lot more than that.

[@ontarget1911]

Solder your crimp connectorsnfor less resistance to current.

[@sherylg2284]

it's actually a 2.2M olms resistor not 2.2k resistor if you use a 2.2k resistor it won't work, I know from experence.

[@shiftyairsoft]

How much watt?

[@Doile911]

what is the song used under this video?

Specs on mosfet

[@AirsoftingTutorials]

No just a non ab simple mosfet, I am not keen on ab fets because it wears out the motor quicker.

[@SuperOldEnough018]

The heat shrink kinda destroys the purpose of the heat sink

[@daveog6429]

Need to use a antistatic wrist strap otherwise you risk damaging the mosfet which can result in it shorting and catching fire!!!!

[@simonbrisebois-therrien2775]

lol, this is most likely to not happen...

[@enaneitor0086]

Lmfao I know this comment is 7 months but what the fuck does this guy think static is? Some kind of nuclear power energy?

[@JohnJaggerJack]

You lost me the moment you used instant glue in power electronics...

[@meowxsquared8678]

He sticked lead to his finger that must have been hurt

[@ontarget1911]

Buy some decent wire cutters and needle nose,

[@Exarhadsgfds]

*ATTENTION!* Do *NOT* solder this MOSFET at 300C or over.

[@AirsoftingTutorials]

About 12 probably. How come?
