New squonkers

[DeloresRose]

A mosfet is just an electronic switch/relay --- many "mosfet" mods also have a pcb with some protection circuitry, but not all. It doesn't look like the gloom clone has protections, just the mosfet switch (I could certainly be wrong though, it is Wednesday ... anything can happen day).

Pretty sure you’re right about this. There’s no literature in the box, and very little description on fasttech. Only someone in comments said it has a mosfet. There’s probably info on the OG out there, but I’m not positive it would apply 100% to the clone.

 

[DeloresRose]

Also, I know there’s debate about whether it can have a mosfet and still be considered a mech. Well, for all intents and purposes, I think yes. I’m not going to argue the point, because I don’t have enough experience or understanding ... but it works like one imho and nothing will blink or shut off if something goes wrong. Mechy enough for me.

It’s not really a debate. If it has an electronic switch and/or protection, it’s unregulated. If there are no electronic components, it’s a mech.

Here's the only info on the Limelight Gloom clone MOSFET I could find:

N-Channel Enhancement Mode Power MOSFET

Description:

The RS40N120T uses advanced trench technology and design to provide excellent RDS(ON) with low gate charge. It can be used in a wide variety of applications.

General Features:

VDS=40V, ID=120A

RDS(ON) <4 mΩ@VGS=10V

RDS(ON) <7mΩ@VGS=4.5V

High density cell design for ultra low RDS(ON)

Fully characterized avalanche voltage and current

Good stability and uniformity with high EAS

Excellent package for good heat dissipation

Special process technology for high ESD capability

Application:

Load switching

Hard switched and high frequency circuits

Uninterruptible power supply


So if someone electronic minded can decode that for us, it would be appreciated

How are you & @AngeNZ like the Gloom?

Sold out so fast? Lol!

I'm loving squonking and really enjoying using the Gloom. I seem to be auto-squonking by the way I grip the mod so I only need to give it a decent squonk every now and then.

With a 0.7ohm coil in it, the output is much more like what I'm used to using on my reg. mods.

Definitely recommend if you want a $20 squonk mod that fits well in the hand, isn't boxy and huge and works well

Thanks!

We asked for more pics of Luna & you give us a Luna nose? Lol!

I’ll take the cute nose though

I'll second that.

I'll second that.

All that stuff is basically describing the specs of the switch, which is all it is. It's designed for high voltage/high amperage loads (40V 160A) with very low addition to the resistance in the circuit. They're usually made for very rapid response on/off times (why they're good for high frequency switching) usually in the 40-50 ns range (don't see it in those specs), which from our perspective is essentially instant fire. But the mosfet by itself is still nothing more than a solid state transistor switch, and has no inherent safety features. Everything else you'd associate with "safety features", low resistance cutoff, short protection, reverse polarity protection, battery state information and low volt cutoff for a drained battery and all that stuff requires additional components on the pcb.

It's just for allowing a fire button that can be electronic rather than mechanical in design.

It doesn't take much to to add rudimentary safety features. Low-voltage cut-off is close to intrinsic. Look at the RDSon vs. Gate Voltage curve for these devices. To add short circuit protection, all you really need to add is something that measures voltage drop between source and drain while firing, to cut off the gate drive if that voltage drop is too high.

Thanks Eskie - that is what I've figured from reading FT forums about the Gloom. The MOSFET controls the switch and that is about it

Noticed today that FT have removed the 3 Gloom skus completely - they were showing up as 'discontinued' yesterday. Tried to click on the SKU of my order below and it no longer existed:

Basically the mosfet allows to you use a small switch to fire the mod instead of a 30A type of switch you find on the Pulse BF. Something has to handle the current draw and since there is no room for a heavy duty switch in there, the mosfet was designed to do the heavy lifting.

I'm sure it would also be a very easily user replaceable part, if one (or a case) could be sources.

 

[Mordacai]

I've noticed 2fdeal have some Gloom style squonk mods available at less than $25 folks.

 

[AngeNZ]

I really really wish I could unsee the
Vicious Ant Spade DNA75C mod

 

[Mordacai]

@AngeNZ the YiHi SX485J (SL Class chipset) VA Spade 21700 looks nice as well. Also a little cheaper.

I looked on VA site after seeing a positive review. I'm ready to jam it in a cart, but can't find it? This is the form factor I've dreamt of since 2011!

Nevermind. I thought this was the Club Omega from VA

 

[Mordacai]

@Dougiestyle, they're in the stabwood collection.

I looked last night and they were all sold out. My credit card sighed in relief.

Love the rdta squonk action!

The club is on VA now. I’m interested in that as well. Note that if you buy one, at the bottom of the listing you choose mtl or dl for the rda. I watched Mike vape’s review and either he didn’t mention which rda he got or I missed it.
