Hacking the Vuse E-Cig to Fully Use Cartridges and Allow Refills

If you've ever used a Vuse e-cigarette, you may have noticed that eventually the unit will say the cartridge is empty and no longer allow you to use it. Unfortunately, the cartridge isn't actually empty but the cartridge keeps track of how much it was used and has a cut off when it reaches a certain value. In this article I'm going to show you three ways to prevent the cartridge from reaching this cut off point. One method is very simple and can be implemented by anyone. The second is more convenient but does require a bit of work initially, and the third I haven't tested. First though, let me give some background on how the unit works. From their website, 
VUSE is the only Digital Vapor Cigarette designed with a SmartLight™ Indicator to always keep consumers informed. The SmartLight Indicator informs on both the battery and Cartridge life. The SmartLight flashes white for two seconds when the Cartridge is getting low. When the SmartLight flashes white continuously, it is time to change the Cartridge.

VUSE is an electronic cigarette designed with "Smart Technology," according to their website. The VUSE Digital Vapor Cigarette contains a VaporDelivery Processor that uses algorithms in the same way a computer does, therefore it is "digital." The VaporDelivery Processor in the PowerUnit, working with the SmartMemory™ microchip in the Cartridge, monitors and adjusts the power and heat delivered to the Cartridge up to 2,000 times a second, ensuring consistently satisfying puffs.




As you can see from the picture above, the main processor (Atmel ATtiny84A) is in the battery pack, but the cartridge also contains an 8 pin eeprom or microcontroller where, among other things, it keeps track of how much it was used. While I don't know for sure how it works since I don't know the technical specifications of the chip used, I do have a pretty good idea what it is doing.

This is a picture of the main processor on the battery pack, this is located at the tip of the unit under the LED's that light up.
And this is the circuit board from the cartridge.




There are three main operations that happen when you take a puff.

  1. The Vuse battery will only work with Vuse cartridges, so the cartridge authenticates itself with the battery's processor and this communication (and possibly all communication between the processors) is encrypted. This makes it much harder to eavesdrop on this communication. 
  2. Power the heating element, as mentioned above, the battery's processor monitors and adjusts the power delivered to the cartridge using data it receives from the cartridge unit. I won't go too into how this works, but from the numerous patents (excerpts quoted at the end of this article,) of theirs that I've read, it likely monitors the airflow through the battery pack, and the resistance of a fusible link and the heating element located in the container. Keep in mind that the unit is calculating and adjusting the power up to 2,000 times a second.
  3. Having calculated how long or intense the puff was, a value is incremented (or possibly decremented) in the cartridge's microcontroller's eeprom. Note that some people think this is a simple puff counter, but I think it is more advanced than that. If you don't know what an eeprom is, it is just memory that can be read and written like a hard drive. An eeprom doesn't need power to retain its contents, unlike other types of memory. 

Step number 3 is the one that we care about. Because the puff value is written to the eeprom at the completion of a puff, the easiest way to keep a cartridge from expiring is to disconnect it quickly as you take your puff. Unfortunately the connector that connects the battery and the cartridge isn't very dependable and will probably end up breaking at some point. So another option is to carefully take the battery compartment apart and rig a tiny push button switch to the tip of the unit that disconnects the negative terminal of the battery. You can see this connection in the image below, the black wire is the negative terminal and it connects just below the LEDs and main processor.



One way for Vuse (R.J. Reynolds Vapor Company) to prevent this would be to increment the counter to the maximum value a puff can be before the puff starts and then once the puff is done, subtract a value if the puff didn't reach the maximum. Eeprom writes take a few processor cycles to initiate and around 5 to 10 milliseconds to complete. This along with the fact that eeproms can only be written to a limited number of time before they fail (usually 100,000+ but could be less on cheaper components,) is why you wouldn't want to constantly save the value during the puff.
There is a third method that others have reported that will allow you to reuse a cartridge and this method is easier than adding a switch and far more convenient than removing the cartridge every time. This is to sever the connection of the LED on the end of the battery pack. I believe it is this LED

I haven't verified that this will work, and you need to be careful not to damage other components, especially since the main processor is on the other side. If it does work though, it is fairly simple and the only downside is that you no longer have the white LED to indicate that the device is in use.


Thanks for reading, if you like it please share. Leave a comment and let me know if this worked for you or if you have another idea.

Here is a link to the photos I took during the teardown.



The big pads on the image above are likely ISP pinouts for programming the ATtiny microcontroller. 

Here is the pinout of the main processor. Pin 14 connects to the white LED, and pin 15 to the red.


So here are some extra images. This is the inside of a cartridge.




This is the battery charging circuit located in the battery pack where the cartridge would connect.



 Here are some excerpts from some of R.J. Reynolds Vapor Company's patents.

The present disclosure relates to an aerosol delivery device including a variable output flow sensor. The variable output flow sensor particularly can be a flex/bend sensor wherein output from the sensor varies based upon changes in electrical current flow (e.g., resistance) along an extension of the sensor relative to flexing or bending of the extension resulting from airflow across the extension. The disclosure further provides methods for controlling operation of an aerosol delivery device through utilization of a variable output flow sensor. In particular, control of functional elements (e.g., a heating member, a fluid delivery member, and a sensory feedback member) can allow for real-time changes in the operation of the aerosol delivery device relative to airflow through the device.

In various embodiments of the smoking article, the heating connection comprising a fusible link and a heating element is in electrical connection with the power source and the control component when the control body and the cartridge body are engaged with one another. The control component can comprise a microcontroller. Furthermore, the control component can be configured to selectively actuate a first electrical current flow of a first set of conditions from the power source to the heating connection when the control body and the cartridge body are engaged, wherein the conditions of the first electrical current flow are insufficient to initiate heating by the heating element. The first set of conditions can comprise a voltage that is substantially the same as a voltage that defines a working voltage for the heating element and a current flow duration of about 45 milliseconds or less (e.g., about 5 milliseconds to about 25 milliseconds). The working voltage can be about 2 volts to about 6 volts.

Various embodiments of the smoking article further comprise a current sense resistor, wherein the current sense resistor is adapted to establish an indication of the fusible link status. The control component can be further configured to initiate a command function based upon a cartridge status interpreted from the fusible link status indicated by the current sense resistor. Specifically, the current sense resistor can be adapted to sense a first resistance across the fusible link and a second resistance across the heating element. Sensing of the first resistance can be indicative of an unused cartridge. Sensing of the second resistance in the absence of the first resistance can be indicative of a used cartridge.

The control body 80 includes a control component 20, a flow sensor 30, and a battery 40. Although these components are illustrated in a specific alignment, it is understood that various alignments of the components are encompassed by the present disclosure. The control body 80 further includes a plurality of indicators 19 at a distal end 12 of the control body shell 81. Such indicators 19 can show the number of puffs taken or remaining from the smoking article can be indicative of an active or inactive status, can light up in response to a puff, or the like. The indicators can be provided in varying numbers and can take on different shapes and can even be simply an opening in the body (such as for release of sound when such indicators are present).

Generally, in use, when a consumer draws on the mouthend 11 of the cartridge, the flow sensor 30 detects the change in flow and activates the control component 20 to facilitate current flow through the resistive heating element 50. Thus, it is useful for air flow to travel through the control body 80 in a manner that flow sensor 30 detects air flow almost instantaneously.
Read more: http://www.faqs.org/patents/app/20140253144#ixzz3ojEccwtz


The control algorithm may call for power to the resistive heating element 50 to cycle and thus maintain a defined temperature. The control algorithm therefore can be programmed to automatically deactivate the smoking article 10 and discontinue power flow through the smoking article after a defined time lapse without a puff by a consumer. Moreover, the smoking article can include a temperature sensor to provide feedback to the control component. Such sensor can be, for example, in direct contact with the resistive heating element 50. Alternative temperature sensing means likewise may be used, such as relying upon logic control components to evaluate resistance through the resistive heating element and correlate such resistance to the temperature of the element. In other embodiments, the flow sensor 30 may be replaced by appropriate components to provide alternative sensing means, such as capacitive sensing. Still further, one or more control buttons can be included to allow for manual actuation by a consumer to elicit a variety of functions, such as powering the article 10 on and off, turning on the heating element 50 to generate a vapor or aerosol for inhalation, or the like.

In particular embodiments, the smoking article can include components that define an electrical circuit whereby a control component is configured to controllably deliver a low power pulse from the power source to the heating connection according to one or more defined algorithms. As a non-limiting example, the control algorithm can include pulse width modulation, which can be based on comparison of a battery voltage with a lookup table. As a further non-limiting example, the control algorithm can include a constant voltage feedback loop, such as through utilization of heater voltage measurements. Specifically, in various embodiments of the smoking article, appropriate wiring can be included such that a cartridge engaging a control body defines a closed electrical circuit through which the control component can controllably deliver a low power pulse (as well as a higher power pulse). The low power pulse can be defined as an electrical current that does not exceed the limits of a fusible link as described herein. By contrast, the higher power electrical current that defines a working status of the heating element (i.e., wherein the heating element heats to a temperature sufficient to vaporize the aerosol precursor material) can exceed the limits of the fusible link.
In some embodiments, a low power pulse can have a voltage, a current, or both that is substantially similar to the same property of the higher power pulse, and pulse power can be defined by current flow duration. In particular, time can be adjusted such that the average power delivered to the circuit is constrained appropriately. In certain embodiments, the fusible link can exhibit a resistance that is lower than the resistance of the heating element. In some embodiments, the fusible link and the heating element are provided in parallel, a majority of the current entering the closed circuit can preferentially flow through the fusible link. When the duration of the electrical current flow is sufficiently long, the lower resistance fusible link will fail and thus allow all of the delivered current to pass through the heating element. Depending upon the type of material from which the fusible link is formed, a sufficiently long current flow time can be about 50 milliseconds or greater or about 100 milliseconds or greater, particularly about 50 to about 500 milliseconds. In various embodiments, the heating element can require that the current be applied for a time of about 0.5 seconds or greater or about 1 second or greater, particularly about 1 second to about 4 seconds for sufficient heating to occur. Therefore, in some embodiments, conditions defining a low power pulse can comprise a voltage, a current, or both a voltage and a current that is substantially the same as the same corresponding voltage, current, or both that is utilized for normal functioning of the heating element, and can also comprise an active flow unit time of about 45 milliseconds or less or about 25 milliseconds or less, particularly about 5 milliseconds to about 25 milliseconds.
In other embodiments, the low power pulse can be defined by a current and/or voltage that can be less than the current and/or voltage that define the working status of the heating element. For example, the electrical current that defines a working status of the heating element can exceed the current delivered by the low power pulse by a factor of 2 or more, 5 or more, or 10 or more. A voltage that defines a working voltage for the heating element can be about 2 volts to about 6 volts, about 2.5 volts to about 5.5 volts, or about 3 volts to about 5 volts. The working voltage is the voltage at which the heating element sufficiently heats to form the desired amount of aerosol during a current flow time as described above.

    2. I have found an extremely easy way to by-pass this and take no technical knowledge, all you need to do is when you have a bad cartridge take it off. Get a new cartridge and take a puff and then quickly, and I mean QUICKLY put on the bad cartridge. If you do this extremely fast the bad cartridge will be reset and the unit will light solid white and the cartridge will reset itself. This works but you have to be fast!

  3. Hi Garrett, thanks for posting this!

    Could you please clarify what you mean by rig a tiny push button? I'm not sure what to do.

    Also have you tested that third method?

    1. The push button idea is a bit tough to accomplish but the idea is to basically have a button that will disconnect power to the main processor. There is a black wire that is ground for the unit, and it connects towards the tip of the battery pack. If you place a button that is momentarily open, meaning power will flow through it unless the button is pressed, then while you are inhaling, just before you finish, you press the button so that the processor never updates the cartridge. Frankly just disconnecting the cartridge works fine for me so I haven't tried the other methods (there is another one I didn't post but it is to ground out the outermost two pins on the cartridge, it shouldn't work in theory because the cartridge couldn't be authenticated, but I'm told it does.) I don't see why the third method would work, after I posted this I mapped out most of the pins on the main processor and if I recall, it doesn't look like severing that connection will break any other part of the circuit. My guess is that you just won't see a light to tell you when it isn't working. It is an easy method to test and I may do so in an upcoming youtube video.

    2. Thanks for the clarification Garret. Seems like the push button thing would be tough to put together. I've been disconnecting the cartridge before each pull is over and it was working fine. Until it stopped recognizing the cartridge was event there (red and white blinking) but it did extend the life while it worked.

      Delete
    3. Perhaps one of the pins on the cartridge got bent and isn't making contact, you could try to gently bend them with tweezers or something and connect it a few times to see what happens. The other thing that can happen is the heater element gets burnt out and then the cartridge will no longer work either.

  4. I have a battery pack that for an unknown reason has quit lighting white when Inhaling. It does not blink white when cartridge is low. It kept working so I kept using it. It wasn't until I started getting a bad taste and barely and smoke that I realized it will continue to allow hits on the cartridge indefinitely. I have no idea how this happened but i am not complaining. I had a box full of "spent" cartridges and I have now been going through them some times getting 30 or better puffs from them. I'm really curios to find out how this happened and if it can be reproduced

    1. Thanks for the info. Since I wrote this post, I had drawn up a schematic to see if the LED's were also on the communication lines but I thought I ruled this out enough to not need to test the hypothesis. Now I'll have to follow up and test this in a video. If this works, and it's looking like it may, it would work by preventing the unit to communicate with the cartridge.

      Delete
    2. I had this happen a while back and I believe it was due to dropping it all the time. I used it till the battery wouldn't charge anymore. I got about 9 months of recharging it and probably double the amount of juice out of each cartridge as usual. I'd pay $20 for another battery like the one I accidentally made. Hell, I bet I saved 5 times that amount just to squeeze every ounce of vape juice out. Hint, hint LOL

    1. I can't seem to get the LED trick to work, but as far as refilling goes it's fairly simple.

      Just cut a small ring of the label off near the "mouthpiece" to get a better view of it, and cut or pry the plastic piece out. I don't think you can pop it out without breaking it off permanently, but it's fairly easy. After it's off, just run some juice onto the cotton and you're good.

  7. I busted the white LED with a pair of tweezers on three different batteries throughout this year, yet all still refuse to use "empty" cartridges, and the damn things still run out.

    Not sure why it seems to work for everyone else and not me, are there any specific details I'm missing here?

  9. Hey i decided to mod my vuse with some spare parts i had from a few vape pens i had laying around what i did was cut the part that attaches to the cartridge off and soldiered it to the thing in a vape pen charger that didnt work the one you screw a vape pen in to that way my vape pen battery can still let me know when the battery needs to be charged and i can take bigger hits cause the button triggers the cartomiser instead of it doin it from you taking a hit plus dont have to worry about the chip anymore all i gotta do is plug the cartridges in the same way as the vuse e cig and its good to go until its trully out.. If u got any questions hit me up at someoner2004@gmail.com

  10. i assume that....you must cut the white light led, before using the cartridges ..cause after you use it and hit the max..the counter in the cartridge is maxed and no matter what mod u did to the battery its too late....so the people who said it didnt work...prob didnt try it after with a new cartridge..the old used ones cant be reset.

  11. I found that taking a drag off a new cartridge and quickly swapping it with an old one(before the white light shuts off) will reset the puff counter on the old cartridge. It's simple to do you just have to be fast. I discovered this while quickly swapping cartridges to see which ones were still good. I used this trick to reset all of my old cartridges. Cheers!

    4. EUREKA!!! it works great. If your having issues with swapping carts do as I did and file down the tabs at the base of the connection point of your battery. there are 3, I filed off 2 and the third halfway. It still holds snug but theirs no aggressive snap or click required to remove. I use a needle nose dropper for refilling as this requires no work to refill.

  13. I found a way to get unlimited puffs off your vuse. All you have to do is look at the circuit board where the white and red LEDs are. On the top of the board look at the opposite end with out the cable. You will see five very small holes right on the edge of the board. Use very small sharpe cutting tool to cutt the middle hole making sure to not cutt any of the other ones. Doing this will allow you to have unlimited puffs and be able to refill your carts with vape juice. Will be be able to also charge your battery with no problems but the red light won't show its charging. Email me at Ericmonroe23@gmail.com for pics . I've done this to about 4 vuse batteries and they work flawless.

  20. This is a bit off topic, but my battery won't charge. Flashed red a few times when plugged in (red and white before completely died). I've only had it a couple weeks. Initially, I had to turn it 1/4 turn, try again; and keep going until I found a "sweet spot". Now nothing.

    Also, how do I access the circuit board in the cartridge?

    ReplyDelete
  21. Clone New Cartridge onto old.
    1. Install new cartridge.
    2. Hold battery in left hand, cartridge pointed away from you.
    3. With right hand, hold depleted cartridge parallel and against the new cartridge. Depleted cartridge must be oriented the same direction as new cartridge.
    4. Grip both cartridges firmly with right hand.
    5. Take a deep breath.
    6. Insert light end of battery in mouth and blow firmly and steadily.
    Continue blowing. Do not stop.
    7. After one second you will see vapor coming from the new cartridge.
    8. Keep blowing.
    9. Now remove the new cartridge and install the depleted cartridge in one smooth motion. CONTINUE BLOWING.
    10. While blowing, remove the battery from your mouth and you should see the white light go off. That is the instant when the count from the new cartridge is cloned onto the depleted cartridge.

    Once You have the hang of it, you can do it while walking, riding a bike, or in total darkness.
    Just remember, Start with NEW and switch to DEPLETED. In all it takes three seconds, one to start, the second to unplug the new, and the third to plug in the clone.
    TIP 1
    Don't continue using a depleted cartridge after it starts flashing white. If you do six or seven times, the battery will zap the cartridge and you will start getting red flashes. That indicates that the cartridge coil is burned out, is useless and can not be cloned onto again.
    TIP 2
    You can re-clone a cartridge once or twice before it runs dry. Once it dries out the battery will zap the coil, causing it to flash red and rendering it useless and un-clonable. Always add a few drops of liquid and the cartridges will last for 10 or 15 times.

    Happy cloning.

  22. I was trying to get access to the circuit board to break the white LED. I thought maybe I could pull the board out a little bit. I gripped the board between a screwdriver and my thumb and pulled a little bit. The board ripped completely out. I first thought "dang it, there goes 10 bucks"... But I put a spent cartridge on it, and it worked, so if you're clumsy like me or can't figure out what LED to break, just tear the whole thing out and it's good.

    I have about 10 cartridges that I pulled out of my trash. They all work now! (I just cleaned out my car and tossed about 30 of them... go figure.)

    Now I need get some liquid to keep these things going indefinitely. Got any suggestions on the best flavors?

  23. You do not have to open the battery unit, or the cartridge on a Vuse to "reset" the cartridge for reuse (everything remains working - charging light, etc). Just hold a "spent" Vuse cartridge in your hand (ready to quickly install it on the Vuse battery) take a hit off a Vuse (with a NEW Vuse cartridge attached), quickly pull the new cartridge off with your teeth and swap it with the spent Vuse. If you do this swap process as quickly as possible (not that hard) it resets the old cartridge "counter" to zero. You can use the old cartridge as is for quite a while, and/or REFILL the old vuse cartridges with the vape juice of your choice - very easily. Refill: by using one of the clear rubbery caps that fit over a disposable e-cig: fill the cap 2/3 full, place the 'connector' end of the spent Vuse cartridge just inside the top of the cap, flip the now connected cap and cartridge over, and gently push the cap down until all the juice flows into the Vuse cartridge. Clean the connector end of the Vuse cartridge well before re-connecting it to your Vuse battery. The only thing I cannot fix (currently) is when the spent Vuse cartridge makes the Vuse battery light flash red and white...any ideas on this?

  24. I believe the Vuse fluid has a high nicotine count, along with unique a processor routine that ensures a great hit from such a small device. As far as flavors for refilling Vuse cartridges, use part "Tobacco" in the highest nicotine count available (I believe 24), mixed with another high nicotine count e-liquid of your choice (2/3 tobacco e-liquid to 1/3 other flavor). "Tobacco" flavored e-liquid is the most "neutral" flavor I have found. Then "reset" and "refill" the Vuse cartridges per the instructions posted.

  25. What about the pin 14 on the main processor. Cut the pin and no white light? I would like to do with out the light... also who needs a whitelight if your cartridge does not count your puffs and you don't need to be alerted about it dying? That was my first thought seeing the main processors pin 14 goes to white light. And if you bust white light do you have to reset cartridges or they just don't stop until the juice is gone right? I have not disassembled one yet and I will to just play around with it myself.


    Plus I would like to be able to be more discreet with it at times so I am all for eliminating the white light.

    If you have any info on cutting the pin please email me ASAP because I fell I may be throwing away $ with some experiment. Lol

    And what about bigger hits? What about better air flow?

  28. Thanks for the hacks the blowing swap out works great and using a needle dropper to refill was easier than cutting the plastic. I wish other pens with refillable carts had the buyer battery.
