Doing 5V isn't hard. Doing 5V right is. It is really easy to add a resistor or regulator to a mod, but the smart way to do 5V is with PWM. PWM will lessens the strain on the batteries and doesn't waste extra voltage as heat. The Pulse is the only device in the works that uses PWM, though I'm sure it is only a matter of time before others copy the idea.

Very interesting. Here is a thread on the Pulse for those interested.

I don't know if there is a newer updated thread - if there is one please let us know.

That's the only thread on the device on these forums. There isn't much else to say about it right now, since they're still in the prototype testing stages. It will be at least a couple months before they're ready to start selling them.

Switching power supplies are so ubiquitous these days (you're probably within arms reach of half a dozen and don't even know it) that it is almost bizarre that it has taken so long for someone to make a mod that uses one. Well, unless you count the ego and its clones. Making a circuit to boost 3.7V up or buck 7.4V down to 5V is incredibly simple by EE standards, but just barely out of the capacity of the average DIY mod builder.

I sincerely hope that the Chinese figure out that this is what the American market wants and starts making some smarter mods. While I applaud Cisco's work on the Pulse, the fact that it's going to sell for "well over" $200 is a bit of a turn off. The actual electronics needed to make a PWM adjustable mod are silly-cheap, and the board could be designed in a couple hours by a professional electrical engineer. The engineering complexity is less than the average digital watch that you get for free at McDonalds in a happy meal. Adding a variable boost board and a tiny LCD display to a device like the ego could add less than $5 to the manufacturing costs if done in high volume. Adding built-in USB charging would add less than a dollar. I don't know if it's lack of vision or lack of understanding market desires that is holding them back, but I hope someone sets them straight soon.

How does the joker compare to, say the GLV, in size? I thought I saw it uses different batteries that I'm not familiar with so I'm not sure whether it is as slim as it looks or if it is just longer so it looks slim in the pics?

Here ya go:

That is the new, shorter GLV also. The GLV is pretty light, but the Joker is even lighter. It feels like you're not really even holding anything! It uses 2 3V batts.

Well I'm a big fan of the Fistpack. Yes it's expensive but it's so versatile. For me, expensive is the drawer full of $100 mods that will never see the light of day again since receiving my Fistpack!
- 4 voltage settings with the flick of a switch.
- 2 day battery life
- small size
- USB charging
- battery charge indicator
When you think about it, what more do you need?

The problem is that there is not enough demand to justify those startup costs , Ya a small LCD display like on a MP3 player is cheap @ 100,000 units , for 500 units it is NOT cheap , finding an OFF the Shelf LCD display is not easy .
I understand what you are saying but in qty's of 500-1000 units all this stuff adds up ( not to mention the engineering time and $$ )
A PWM design is easy and cheap to make , they will be here very soon IMO ( Just ask Cisco ! )
We are working on a design that requires custom molded enclosures , this takes a lot of time ( it has to be right the first time ) and a lot of $$ to design and bring to market . I dont know if you have ever done anything like this before but it is a difficult task and takes time and $

To design to a market that can absorb maybe 2,500 units it is a totally different process than to do 100,000 units.

Just saying , you have good points BUT need to be aware of the issues the MFG's face for small volume manufacturing. and YES these are small volume devices.

There's enough of a demand to make the ego and (at least) three clones, and some of them have PWM circuits.

If you're one guy in a garage in the US, it's not feasible. If you're a Chinese factory that churns out 10-20K batches of electronic doodads all the time, it's a piece of cake. Walk down the electronics isle (or even the toy isle) of a discount department store and you'll see hundreds of cheap, no-name Chinese products for under $20 that have way more design and material requirements than a PWM mod. They design and manufacture crap that nobody wants all the time. Here's a product that everybody wants, but somehow they can't be bothered.

I think it's just a cultural thing. Nobody in China wants to do something new. They just want to copy existing designs that have proven somewhat successful. They'll invest the time and effort to make a batch of the five thousandth clock radio design, but nobody wants to make the first PWM mod design. What I wouldn't give for an army of asian slaves factory workers.

So what kind of battery does it use? Is it easily replaceable? There isn't a lot of info on the site?

Oh, and @Redgirl, thanks for the side by side of GLV and Joker.

It uses an 18650 battery that last about 18 hours of pretty heavy vaping. It is not user replaceable. However it should last about 12 - 18 months. You'll need to send it back to Nuck for replacement. Would I rather it was user replaceable? Yes, but there is so much tech stuffed into such a small size it wasn't an option. It's a small trade off for a device that really does it all.

Add a 'drop in' charger (inductive like a tooth brush) or
drop on' (also inductive like the charging pad), and an auto or manual abilty, then you are done. :D

USB charging is only a slight step up from a small wall wart.
Many of us like Auto's.

Sorry a little bit OT here...

I built my own 5v.... 2x3.7 with a regulator... anyway...

...just wanted to chime in and say that my 510 atomizers hold up good on 5v as long they stay wet... if they dry up or burn too long it's no good.

Seems like 1.5 - 3 seconds on 5v is equal to a 5 - 7 second draw on 3.7. ... maybe I need to try HV atomizers?

3.7 is a more leisurely vape... 5v is like a hard hitter.

+1 for building your own
