Trigger Master MOSFETs

[ShelledPants]

Oh hai guyz,

So I just finished installing a Trigger Master MOSFET in my CA Sportline and I'm seriously happy with the results. 3-round burst for the win.

So I pose a few questions:

Do you plan on buying one?

If you've installed one, how did you feel the installation went in terms of ease?

How do you find the long term (several games) with the upgraded AEG?

I'll be designing my own this summer with an X round burst that doesn't need to be programmed each time you plug it in. It will be more adaptable.

I just got it yeterday. Does it get hot? I am going to put it where the fuse was. Luckily have some Deans connectors. Did you have to adjust the 3 burst timing in programming mode or did it shoot 3 rounds correctly from the start?

Naglfar: it remembers your settings even after you unplug the battery.

I've installed three so far (as well as some 3 round burst unit I was given, non programmable but works very well, even if it's only 2 round burst and full auto, which I actually like a lot better) in different guns, and installation skill required ranges from intermediate (say full stock gun, battery in the back) to very advanced (battery bag on stock, TM unit in front foregrip).

Overall hooking it up is easy, but wire management is where the real challenges lie, as well as being able to work on your mechbox in the future (aka. means of disconnecting the wires).

Is a VERY capable unit, lots of range in adjustments.

Syn, it's doesn't get hot, you literally take out your wiring harness and install the TM, usually it's said to replace the fuse with the unit, largely because there has to be a place to put the unit, and it's about the same size as the fuseholder. And once yo install it and hook it up, it *should* be able to fire burst as a default (according to Don), but with my first, I had to program it to burst mode to get it to work.

Oh, I'm going to be helping Don out, I'll be populating most of the TM circuit boards in the future. Populating meaning soldering the components onto the boards.

It doesn't get hot when it runs normally. But if it's anything like the SW-AB-LONG (i.e. if the resetting fuse component is similar, I think) and you "trip" the fuse...don't grab it with your bare hands. When I tripped mine, it was extremely hot to the touch (not for too long but enough to notice).

I had a strange error when I first plugged it in, I think my motor was too deeply seated, as it would start up, and I would pull the trigger, but it would restart the system. after seating my motor again, it fired no problem. Did the 5 shots, then threw it into auto and it happily fired the 3-rnd burst.

Ya, I was working on Jackals rifle the past few days and got the same reset, Was because the piston would pull back and jam at the rear, causing more current draw from the unit, making it shut down and reset. The problem wasn't the TM, it was the DeepFire mechbox and some other parts that didn't like each other.

I'll give it a try for sure. Maybe advanced programming in future by stopping fire when mag is empty (mags job too)

I'm not sure how you could rig that up with a stock Trigger Master as there is nothing to tell it when the last bb has fired. :| The PTW's system for this is mechanical, no?

Good idea. Could see about a magnetic sensor in the magwell and mount a small magnet on the follower in the mags, when it gets to the top (out of ammo) the TM cuts off.

[Roughneck]

I would be all for that system

[acorn_giblet]

That's actually a really nice idea... Most of the other systems I have seen rely on some mechanical interference from a protrusion on the follower and seem to be a bit touchy...

This idea is being thrown around in another thread right now too. Seems everyone's in a creative mood.

There are some posibilities to use the push-pin in the mag that follows the last bb. When the Mag is in empty position (even if 2 bb's aren't in the hop-up), this plastic pin is in contact with the top of the inner mag container. If we add "+ / -" contact in the mag weel and on the top of the mag, then the push-pin when empty will connect those 2 electrodes that send and info to the MicroCPU "hey, stop firing, no bb's left!" But we do need the do the mods on each of our mags.

I just opened a mag 1 hour ago and began some drawings. it's just theorical, but logicly doable. I'm not particulary good explaining, but I'll test it in the next days (without MicroCPU). Programming is not my strengh.

If I can, I'll take some pictures of the work.

since its timed. in theory wouldnt it be off time when your battery starts to run low?
