airsofthacks.com Custom products now Available

Just one of several new things coming to airsofthacks.com soon, here are our custom, made in Ireland, mosfets.

There are two options to choose from, our standard mosfet and our active braking mosfet. Both will provide an excellent upgrade to your AEG, reducing wear and tear and improving performance. The active braking mosfet has all the same features of the standard model except the motor is stopped when you release the trigger or when the cut-off lever engages.

Also, we have our Auto Reset Fuse, this will protect your AEG just like a nomal fuse, but when it breaks, just wait a couple of seconds and it will reset itself. It’s also got a much lower resistance than a standard fuse, so if you were thinking of removing your fuse to lower resistance, now you can have the best of both worlds.

Airsofthacks.com products can now be purchased online directly via eirsoft.ie, full details on each is below;


Standard Mosfet (RRP €30)

• Our standard Mosfet wiring harness.
• Highly recommended for AEGs to promote longevity and essential when running batteries high than the stock 8.4v
• Replaces the stock wiring of an AEG
• Reduces wear on trigger contacts.
• Ideal for use with batteries of 8.4v and 9.6v
• Can help increase Rate of Fire
• Can increase battery life

Active Braking Mosfet (RRP €45)

• Upgraded Mosfet wiring harness with Active Braking.
• The same as our Standard Mosfet with added Active braking.
• Braking prevents the motor from overspinning when you release the trigger or in semi auto mode. This eliminates the problem of having 2 shots instead of 1 in semi auto commonly seen in high speed setups.
• Highly recommended for AEGs to promote longevity and essential when running batteries higher than the stock 8.4v.

Auto Reset Fuse (RRP €8)

• Direct replacement for your stock AEG fuse, breaks just like anormal fuse to protect your AEG.
• Automatically resets itself; no need to open your AEG and replace the fuse.
• Has less resistance than a standard fuse, making sure you get the most out of your AEG while still protecting it against shorts.
• Recommended for use with our Standard Mosfet and Active Braking Mosfet.

Mosfet with a 3 round burst maybe?? Is that possible and can it be used in any AEG?

airsofthacks

Yes and Yes.

I'm working on a couple of options to do that at the moment, but it's a matter of finding a balance between cost (too expensive and nobody will want it) and ease of use (too awkward to use/install and nobody will want it)

Two options are;

Slightly expensive model; Computer controlled, plenty of fancy features, installs like a normal mosfet and requires no modification. This model will shoot a 3 round burst in full auto and then "roll over" to full auto after a minor delay if you keep holding the trigger.

Cheaper model; No computer control, timer based, will need to be calibrated by the user on initial installation and will not roll over to full auto. Could potentially do this as an "inline" model or as an add-on board for the active braking mosfet.

peter-pantslez

i lie the sound of the roll over to full auto!!

how much are we talking about when you say slightly expensive??

airsofthacks

Based on a quote I got recently to have them manufactured in Ireland, about 100euro retail price.

I'm looking at having some made in china though, will see how that goes.

however would be more interested in the more expensive one with the cheaper tag which i'm sure everyone would be

I'd try and get the retail price as low as possible, but realistically it'd probably still be around 70euro at the cheapest.

TheDoc

I have a guy I know acquiring a mosfet or some sort of thing, that will stop his gun firing after 30 rounds, therefore like an electronic bolt release. Once the next mag is inserted the rifle then operates again.

I was hoping to acquire something like this for milsim games. I don't know where he is getting them from but I'll report back what I hear, and how they perform.

Should they actually work well....it would completley null the need on my behalf of buying a systema,

airsofthacks

Yup, I know the one you are talking about, only problem is it requires a sensor/switch either in the magwell or on the charging handle to reset the counter (not that big a problem tbh), there is also a variant that can do simulated jams randomly when you are shooting, requiring you to pull the charging handle to "clear the chamber" before shooting again.

Cheeky monkey

Docs one sounds much better then the 3 round burst one as long as you can turn it off or increase the limit easily

Ah well nothing is cheap these days anyway!:p

AlternateID

Think you might be reffering to the Cheetah mosfet Doc.

As far installing the mosfets go is it recommended that novices attempt installation themselves? (i.e have you included idiot proof instructions? Lol) as for the 3 round burst? Would personally like that a lot!

these sound deadly too. can you get these and what would the retail be on them?

At the moment, no, ill be doing the 3 round burst option first, I'll look at extra features like those above, but it's a matter of supplying what will sell to be honest.

Yea, the instructions are as straight forward as I could make them to be honest, but they do come with a warning that you need to know how to open a gearbox and be able to solder to install them, alternatively, I can do installation or eirsoft.ie do installation aswell (for a fee of course )

Thats the one.

Simulated blockage you say, I wouldnt mind something like that.

But I'm going to guess this setup would cost around €150+ if a 3 round burster is in the ton mark.

yeah but the other option is a GBB or Systema so i would much prefer this option as well so hopefully u get enough interest to actually supply it

I'll get the basic 3 round burst model done first, then we'll start looking at realism modifications

a 3 round burst would complete my g&g mp5

any update on the three round Mosfet kd ?

airsofthacks

The design is finalised, hoping to have prototypes in a couple of weeks and then will start taking pre-orders from retailers once the prototypes have been tested sufficiently.

airsofthacks

As per my blog post;

I’ve secured a supplier in Asia for manufacturing velcro-backed embroidered patches. Prices are very competitive and much cheaper than any manufacturer I was able to find locally in Ireland.

If you require patches for your team, email sales@airsofthacks.com and I will get a quote for your design.

Example of patches I’ve had made are below:

Sorry for the delay in reply, was away for the last couple of weeks.

The 3 round burst mosfet has been slightly delayed due to minor design revisions and also summer holidays of both myself and my supplier. Will get moving on it ASAP.

Cheers

Necro thread ftw........


So I had a "Why Didn't I Think of That Before" moment the other day and I've just put together this;

https://www.youtube.com/watch?v=Pu0V2mS3gYA

Yes, the little board the gearbox is attached to is controlling the 3 round burst, and yes the whole thing can be made alot smaller and can be fit into a normal foregrip/stock.

The basic idea is based on the extreme fire 3 round burst system using a microcontroller to do timing and other various tricks. The code I've put together is very much in an alpha state, but hopefully this could turn out quiet well and in a few weeks time I should be looking for beta testers.

Looks really cool. Volunteering for testing if needed.

I'll volunteer too, ya know just cos, you need more than one and stuff ¬¬

Ah sure I'll volunteer too so

kdouglas

ha, thanks lads... now what if I say the prototypes will cost 100euro? Still wanna volunteer?
(just kidding, beta testers will, at the very least, get them for cost price, maybe free if i'm feeling generous)

Anyway, I've ordered parts to make one prototype small enough to install into an AEG, once I get that sorted in my own gun I'll look into getting beta-tester prototypes made, probably just 2 or 3.

I'm also open to idea's as to what other things I could do with this, it is fully programmable and I'm going to look into mimicking alot of the functionality of the extreme-fire unit, such as automatic burst timing adjustment, feedback through vibrating the motor etc... but in theory, I could even add an LCD screen with shot counter into this thing (expensive though).

DeBurca

I think its just great and would be happy to help with the testing

Private Snafu

I'd love to help out however I can if it means beta testing I'll gladly do it

pyro jim

same here if you need a hand, i'd happily pay, 3 round bursts would be the job.

AlternateID

How small do you think you can get these Keith? There's not a lot of room in my current gun.

Y'know what'd be cool ? You could hook up a mobile phone speaker to it, and program it so that 2.5 seconds after an adjustable number of trigger pulls, a voice screams "HERE YOU - TAKE YOR FUKKIN HITS !!!"

Masada

I'll test one if ya want keith.,:)

Since your looking for idea's too though, an integrated auto reset fuse would be a god send i reckon, if its not already there/on the cards.

P.K

If your still looking for testers i can give a hand if needed

kdouglas

AlternateID wrote: »

I reckon about 3-3.5cm long by about 2cm wide and about 0.5cm deep, approximately the same size as extreme-fire's sw-evolution I think.

Some thing, to simulate, round jams, And when your out of ammo, for mid caps, some micro sw, or some thing like that.

Private Snafu

the ability to stop the AEG firing after a programmed amount of shots requiring a reload to continue..... would be handy

desertstorm

program to give effects of overheating for MG's

such as in most computer games where after X time firing an MG, you have to wait for the thing to cool down

just out of interest what language are you using for the programming? Basic?

Both doable but would require extra wiring in the AEG to have a "reload" switch somewhere, probably hooked up to the charging handle or some such, so while I could program this in, every AEG would be slightly different in how you would install the switch and what size you could fit.

The environment I'm using uses Processing, which is basically C and can make use of C libraries.

Re: Empty mag stopping an aeg from firing;

Have a look at the cut off switch in Star auto winder mags, a similar micro switch in the feed tube of the hop up could determine if the mag is empty, ie, no pressure in the feed tube, then you would have an aeg that would stop firing on empty.

Simply have the micro switch in circuit with the trigger switch leading to a standard mosfet.

That's a fairly straightforward mod to do the way you describe, and wouldn't even need a microcontroller to do it.

Unfortunately the really fancy stuff like anti-dry fire, realistic reloads etc... tends to require modifications to the AEG beyond that of your average skirmisher.



In other news, got the miniature version of the microcontroller I ordered this morning, it's quite small and thinner than I expected, adding in a couple of mosfets and possibly an auto reset fuse and this should still be quite a small little package.

I've done a bit of playing around with it today and got it set up for programming, also tested code that will allow me to vibrate the motor (without firing the AEG) to give user feedback, credit to gandolf from extreme fire for the idea of how to do this from his sw- series computers.

kdouglas

An interesting day of testing, I've blown up several mosfets and fried one of my microcontroller boards (note to self; overvoltage is a bad thing) but thankfully I have spares.

I've done a fair bit of playing with the code and now have the ability to use trigger pulls for user-programming with motor vibration as feedback.

Setup modes for normal, 3 round burst with full auto roll over and locked single shot only mode (no full auto at all).

Have also written the code necessary to adjust the 3 round burst timing on the fly, this will allow for different gun setups (battery, motor, gearing, all affect timing) and also adjust the burst time as your battery gets lower.

kdouglas

Random trigger jams anyone?

I have it set to 1 in a 1000, which means if you're anything like me and generally use single shot/bursts most of the time, you could easily go through a days skirmish and not have a jam occur.

I'd like to alter the random jam code so that the more often you shoot in full auto, the more likely you are to have a jam, I'll think about it a bit today and see what I can come up with.

In the meantime, anyone have any thoughts on the probability of a jam occuring? is 1/1000 too high/too low?

MerryDespot

Ok - I know we need to be careful with wikipedia, but think for what you're asking this is ok.

60,000 rounds fired - stoppages were:
SCAR - 226
XM8 - 127
M4 - 882
HK416 - 223

So dividing by sixty (and rounding) - this gives:
SCAR - 4
XM8 - 2
M4 (a woeful) - 15
HK416 - 4
