MOSFET with active break

[Dannn]

Has anyone made and used one ? Just ordered all the components, seems a very simple task !

They are about £30 to buy but components are cheap

[Lozart]

Just buy one.

[Sitting Duck]

No coz most setups will not really really need them

 

Plus it puts a minor strain on motor

and the Rusty's guide has stopped recommending them but left info for reference only

 

Got a few 4045's or whatever the position fet's are to go with my 3034's but as of yet if done correctly a high rof gun most likely not needed.

It seems to be said a m120 & SS a couple of teeth is better way to stop double cycle and also help avoid PE

 

Which an AB fet doesn't help when firing on full auto

 

For most builds an AB is perhaps not needed is my feeling

[Dannn]

Don't need the active break bit?

Seems a waste to buy when the components cost £4.50 !

[Sitting Duck]

Good 3034 can be built for half that price -£2:25

if you buy say 10 genuine ones

 

Avoid any mosfet's from fleabay China component sellers

They are fakes and just melt under load

 

£2:25 will cover gen 3034, diode, 2 resistors

All you need is time - put a few together at same time

Decent wire n shrink wrap

 

Best basic 3034 is your own one if its genuine

 

Failing that firestorm £10 baby micro fet is worth a look

if peeps just need a good basic tiny fet

[Lozart]

It ultimately depends on whether or not you need active braking.

I use AB mosfets in my guns and while yes, it may put some additional strain on the motor none of them have had an issue yet.

 

Plus....I'm all for being thrifty but seriously ready made fets are so cheap now why would you fuck about making your own? Yes, £30 is more than £4.50 but the cheap DIY ones don't come with all the features you'd get in even the most basic Gate device.

[Sitting Duck]

Depends on how many fet's you need to buy/make/fit

 

To make just one it may not be worth buying

and making it, though whilst you solder in any

ready made fetbthe iron is on anyway

so a few more ttzzzssstt's ain't much more agro

to put your own fet together.

Hence if you got it all ready may as well make up

2 or 3 basic fet's I guess.

 

The baby baby micro firestorm fet is worth considering

basic non AB fet but £10 delivered ain't bad for a one off fet.

As for bells n whistle fet's - guess it is up to everyone what they fit/use in the end

[Dannn]

The resistors come in packs of 25 they are a penny each !

And the midgets in 2 packs It's all from RS in the UK so it's good quality and there's a really good pdf guide to making them that I've found

[AK47frizzle]

I'd recommened getting the AB fet because it puts the piston in the right place after firing full auto and even semi; I hate having to fire a few shots on semi afterwards to release the tension on the gearbox.

 

Yes it "may" put more strain on the motor but i'd rather have a better performing gun with some wear than less wear and having to reset the damn thing everytime.
