Hi Theops,
When using the Bug in a roller with an 18350, would there be a gap between the outer tube and the switch housing? and when will you release the bug? I need to get infected!

If you leave the washer / spring on the cap, the tube closes completely without issues.

If you want to take the spring / washer out (recommended), it will be necessary to adjust the position of the bottom cap disc:

Would there be a problem leaving the washer and or spring in with the Bug ? ... And if so, could I use magnets to bridge the gap so that I don't have to adjust in the cap disc ?

when are you going to have the Roller SS-IM back in stock?

Extra contact points always introduce some resistance, especially if the contact pressure is too low for the interfacing materials.

Magnets / spacers / springs always add resistance that may be significant if the contact areas are too large and too flat, especially if they are not plated with a noble metal.

So, from a performance perspective, it's best to put as few things as possible in series with the battery, otherwise you might need to keep everything squeezed tightly to minimize voltage drop.

From a practical perspective, there is no reason to keep the spring in place when using the Bug, especially in 18500/650 mode.

In 18350 mode, we have found that keeping the spring / washer on the cap when using the Bug compresses the spring quite a lot - so the losses on the Bug are more or less compensated by the added spring compression. Spacers, however, should be avoided at all costs.

Hard to give an ETA, but stock is constantly refreshing. For example, we expected SS-P units towards the end of this month but managed to produce quite a few units last week and will release them in a few days. IM units are re-stocked much more often.

 

[Beeds]

Not a technical question but are there any plans to reduce the postage for smaller items ie the easy twist button ?
As it would make my Dingo perfect , but 12 euros for postage seems a little steep...

Hi theops,
When will you have the bug in stock? I thought it would be available today but it's out of stock?
Thanks in advance

 

[Ben C.]

The Bug is in stock right now, and it was yesterday as well. Picked one up along with a Hive.

Is there a way to change the throw off the switch to make it shorter? Any help would be great thanks.

Excellent question!~ That's a nice thought.

 

[COM76]

Just wanted to thank Atmizone for making such a brilliant mod. The roller is just a perfect quality out and about mod. Im glad a company saw the need for a good looking side button mod on the market and filled it. I highly recommend the roller especially the look of the two toned custom finish.

It's possible, yes, but not easy. You would need to find some way to make the Axle stop a bit deeper. If you can make a thin washer with an OD=8.9mm and an ID larger than the button, so that the button can pass through it when mounted on the Axle, then the added height of the washer will keep the Axle a bit lower.

Im really liking the look and simplicity of the guppy you guys are putting together. I noticed you have a few nice pics of it on your FB page. Could you recommend any other rba's that would look good on top? Possibly provide some pics?

 

[theops]

Anything that's minimally designed and smaller than 20mm will look good on it, especially 19mm atomizers.

The Guppy will be released along with the first version of the Bayou tank, which is an exact match diameter-wise. It's a quite unique tank, so if you are into 510d-carto-style RBAs or 510 cartomizers, you'll definitely like it

Any ETA on the Bug 2?

Any ETA on the Bug 2?

We made a few different prototypes, some with lower-amp-rating modules. Since i) the most common and dangerous fault is a hard-short and ii) the current, high-amp Bug responds plenty fast to hard shorts, we saw no reason to release lower-amp versions.

The current version of the Bug is about as good as a PTC fuse can possibly get - http://www.atmizoo.com/graphic/bug_lab_char.jpg

 

[theops]

By the way, here's some information about the Bug, which has been out for a while now! From Bug | atmizoo vaping modware -

Based around a resettable PTC element, the Bug is a high-amp short-circuit protection module that adds dependable safety to mechanical mods.

Resettable polymeric fuses have been around for quite a while – they provide an easy means of secondary over-current protection, which is fast enough to prevent component and battery damage. These fuses do not ‘burn’ like the traditional ones – they use a polymeric element that interrupts the circuit during an over-current condition. The resistance of such an element is dependent on the current and temperature — a short-circuit quickly brings the fuse to a high-resistance state. When the fault is removed, the device cools down fast and reverts back to its low-resistance state.

Since the performance of these modules depends on the operating current and the fuse / ambient temperature, proper component selection is key to achieving good performance under non-fault conditions.

The Bug is designed to operate with a voltage drop between 0.05 V (at 2A) and 0.15 V (at 6A). Practically, using it with an atomizer resistance down to 0.8 Ohms will have a very small impact on performance, since the resistance of the device is significantly lower than the internal resistance of a good IMR battery. It can be used with atomizer resistances down to 0.6 Ohms.

The Bug is suitable for telescopic mechanical mods or fixed-length mods with a spare ~5mm tube length.

Here’s a set of tests conducted on a new Roller, a Dingo and a Guppy.

The presented method relies on measuring and subtracting the voltage drop component that corresponds to the internal resistance of the battery from the total measured drop. The voltage drop on the battery “outside” the mod is practically the same as its contribution when it’s placed “inside” the mod, since the current is almost the same in both cases (the resistance of the mod is very small compared to the resistance of the load).

Note that the method presented here can be used to calculate the voltage drop on any mod with only basic equipment requirements.

These units are not hand-picked: The results of the Dingo are slightly above production average, the results of the Roller are slightly below production average, while the results of the Guppy are spot-on and are much more consistent on a production level due to its small number of parts.

The Roller tests also include a Bug volt-drop measurement at an approx. load of 4 A (~1.0 Ohm), which is in line with the curve given 2 posts up.
