    Ok, the herb inside gets vaped, it changes color, but I don't get any vapor. Like I said, I tried other cooling units. The bottom screen is fine, it has all the holes open.

    I changed the o-ring on the crafty, and on the cooling unit. I get a little bit of vapor, very small, not like it supposed to be I know I had 4 other crafty units, but by the 3rd pull I get nothing and it's 191 bass temp. Even at max temp I get a tiny little bit of vapor that's nothing. On closer inspection, the herb is not changing color. Just a tiny bit. RIP Crafty.


    Edit: Eventually leaving the herb inside, it changes color to vaped color. I just don't think the heater is up to it anymore.

    So an update on the battery pack ... looks very promising!!! Got my crimpers in this evening, and crimped together some cords after a few tries, first one I installed, the wires snapped (crimped too tight), so I tried again! Got everything mounted, battery pack connected, and it powered up and charged no problem. Wires were a little long making it awkward to get back in. Made a 2nd pack. This one is much, much better. Used the Sony VTC6. I have it charging now and will test once ready.

    I'll report back later with pictures.

    If all goes well, I'll be able to build and sell these packs for $30 a piece. (I'll also provide full instructions for anyone that wants to do it themselves ... the cost to build 1 battery pack exceeds $100 after shipping and tools though!!! I figure I've spent $150-$200 with the waste from ordering stuff that didn't work as well)

    Ok ... so here's an update ... not good news, although it is progress!

    The packs work, however, they take too long to heat. They take maybe 30-40% longer to heat up then the stock pack. I made up 3 packs: 1st wasn't done great, wires were too long, used an LG HG2. Also made one with the Sony VTC6. Also made one with the stock Panasonic 18650PF.

    The 18650PF takes 30-40% longer to heat then the stock 18650PF ... so ...

    1. Connector - took apart the stock one to check, and 100% guaranteed the one I have to replace is identical. If my problem was with the crimp then it wouldn't be the same problem on both packs. The crimps also seem nice and strong (I can't pull them apart even if I try)
    2. Battery - I've tried various batteries including an identical. The tabs are thicker on the stock battery, but don't think that would be it (I'd need to swap the wire harness from the original to be sure)
    3. Wire - this is where I think the problem is ... although I think I have something equivalent, perhaps it's not quite good enough. I'm already over gauge for the connectors (connector supports max 22awg and I used 20awg which looks to be the same as the stock but feels a little more light duty ... this is a top quality silver plated copper wire as well)

    So I think the logical target is the wires ... see if it's possible to go to a small 18awg? Maybe a different strand count for the 20awg?

    Here's a picture of the stock battery pack and the homemade one. (been looking some more and think I just need the right 18awg wire)

    [​IMG]


    Edit: Here's the perfect wire I think ($20 in shipping + $5 for 10' of wire)

    Good news ... homemade Crafty battery pack success! The one pictured is a Sony VTC6 and initial test for heat-up time was 1:20!!! Excellent!

    My mistake last night, is apparently when you first swap battery packs on the Crafty, it gets confused. It doesn't know it was swapped. So when I checked the battery capacity on the app after changing the battery last night, it showed almost full. When I plugged it in to charge through the USB port, in the app it was still flashing between before last and last bar, and charge light had gone to solid blue; the reality of it was the battery was almost dead! So when I tested it, with the app showing a full charge, it actually had very little charge; thus the 2:30 heat-up time. Now that I figured this out today, I plugged in the charged pack and tested (first I drained the Crafty by double-clicking the power button, and clicking it a few more times, as well as left it battery-less for a while)

    I'm going to start testing with this pack tonight to see if there are any issues ... I'll re-charge through USB after my first 2 trial heat-ups I've run, and then I'll test and time each heat up for each bowl, and see how many sessions I get on a charge, how the heat-up times increase after each session, how heat recovery is between hits, etc. (not all of this I'll record hard statistics on ... some will more just be observation based on feeling in comparison to stock pack ...)

    Can you boys please grow up and buy a mighty

    I like have a support group of people that purchased the crafty first.

    Please try a mighty ans buy it it's completely different than a crafty.

    Charging and battery issues are not an issue.

    Note that this is coming from a person that uses to this device regularly for medicinal purposes. I Rely heavily on it.

    Don't get me wrong, that's a bad little boy too. I Sing Praises about my first crafty. But there's limitations. It's a portable Vape. If you understand that it's medication, and only can get your hands on dry herbs,the mighty is necessary. Necessity, I see all other devices as toys.

    Just got my crafty back from RMA with firmware v2.51 - really love the new feature of the light vibration sequence before the auto-shutdown. And great service again ( for the 3rd time now ) I was asking for RMA exactly 2 years after I bought it. My problem was "vibration sometimes does not work" - and no questions asked I got a brand new crafty with all the extras.
    But I think next time I will try to repair myself so thanks for all users sharing their photos and experiences regarding this!

    An update ... my tests with the Sony VTC6 replacement pack above:

    - 1st session: 1:20 heat-up, great heat recovery during session, started the session at 185 and boosted to 195 for the last couple hits (my sessions are typically <5 min. ... maybe an average of 3 min. or so ...)
    - 2nd session: 1:20 heat-up!, great heat recovery, no noticeable difference from 1st session
    - 3rd session: 1:30 heat-up, still great heat recovery, maybe slightly slower recovery then the other 2 sessions near the end, but maybe not (kinda' just theorizing in hindsight that it must have been ...)
    - 4th session: 1:45 heat-up, heat recovery starting to lag, perfectly acceptable performance but not stellar like the first 3.

    After 4th session, the app still indicates I have a half charge on my battery, so I'm sure I could get at least 2 more sessions, but I feel that 3-4 sessions is the cut-off where you get optimal performance and after that your heat-up and recovery times will increase.

    Next I'll be testing the LG HG2 pack to see how it compares :)

    In Germany (Europe?) S&B offer a replacement of battery and wear parts of the Crafty, including a function control for a lumpsum of EUR 75 which I don't find too expensive, keeping in mind the service is done by a professional company in the medical equipment trade.

    Yes, I've heard you can get your battery replaced for $90 USD here. That is a valid option for many where the vaporizer is still in warranty but the battery is not or where the vaporizer is out of warranty. That equates to $90 USD ~= $120 CAD + $30 CAD shipping to CA ~= $150 CAD. This is a very expensive battery!

    Currently, in order for one to replace their Crafty battery, they need to source the correct battery with tabs, and then de-solder and re-solder the wire harness. This is a daunting task for many. The option I have been trying to get to (and have) is an economical replacement that one can do with a very small amount of mechanical aptitude.

    ie. Summary of steps:
    1. remove 4 screws
    2. unplug battery and heat sensor
    3. cut/tear off PVC heat shrink
    4. remove tape holding heat sensor to battery
    5. plug heat sensor back in
    6. plug new battery in
    7. place heat sensor
    8. re-assemble case and secure w/ 4 screws
    An added bonus is with the Sony VTC6 you actually get an improvement in performance over new from the factory :)

    I estimate that $30 USD is a reasonable price for these packs and if sent regular letter mail I can send to anywhere in North America for $5 including packaging. (I'm not doing this for the money ... it's for helping out ... and for interest's sake ... once I started I kinda' obsessed ... I figure I'm about $200 in to build the 4 packs I have ... :lol: ... and one is clearly the "best" from what I can tell so the other 3 are thus of limited use I think!)

    Edit: Here's a document on how to do the battery replacement:

    Nah, I'm pretty sure it doesn't.

    and that it absolutely is, you did a great job there! But then there's the people who have two left hands... or worse.

    I agree though - the costs for the S&B Service in N-America are a bit over the top...

    I've completed my initial testing (I'm pretty high after a dozen sessions with the crafty since last night ... plus a couple with the hopper ...!).

    I posted my results above for the Sony VTC6 which is by far the winner. This battery significantly outperforms the rest including the stock battery!

    After testing the VTC6, I tested the LG HG2, which did quite well:
    - 1st session: 1:22 heat-up, heat recovery and retention was good, maybe a little better than stock
    - 2nd session: 1:32 heat-up, heat recovery and retention was good, but a long, powerful draw can drop the temperature by 10deg (similar to the stock 18650PF)
    - 3rd session: 1:40 heat-up, heat recovery and retention pretty good, recovery a little slower
    - 4th session: 1:50 heat-up, heat recovery and retention acceptable, recovery a little slow

    After 4th session there were 2 bars left. Pretty sure it would handle another session or two, but I wouldn't go beyond 4 just like I never went beyond 4 with the stock battery because the retention/recovery becomes way too annoying. I actually find the magic # to be 2 or 3 sessions w/ the stock battery when it's good, and similarly I think 2 or 3 would be good w/ the LG.

    I also tested 4 sessions w/ my homemade Panasonic NCR18650PF and found the performance and timing to be what one would expect, which is basically similar to the stock battery (not surprising since they are the same):
    - 1st session: 1:30 heat-up
    - 2nd session: 1:40 heat-up
    - 3rd session: 1:50 heat-up
    - 4th session: 1:55 heat-up

    Battery quite low after 4 sessions ... don't think it would make it through a 5th.

    So, in summary:

    1. Sony US18650VTC6, 3120mAh, 30A max continuous: By far the leader. This battery had much better heat retention and recovery and heat-up times. It's performance across multiple sessions was notable. This battery does 3 sessions with no decrease in performance, and the 4th session performance is still as good as a 1st or 2nd from a brand new stock battery. One gets 3-4 sessions easily w/ no sacrifice. After 4 sessions battery still shows half (in the App).

    2. LG INR18650-HG2, 3000mAh, 20A max continuous: Slightly better than stock, but only slightly

    3. Panasonic NCR18650PF, 2900mAh, 10A max continuous: Stock battery. Homemade performs as would be expected.

    I made and inquiry to Storz and Bickel in December regarding cost of a battery replacement for an out of warranty Crafty:
    "Hello,

    Thank you for your inquiry.


    To have the just the battery replaced will be $129.00 USD.


    Storz & Bickel America, Inc.

    1078 60th St.

    Oakland, CA 94608

    oakland@storz-bickel.com
    www.storz-bickel.com"

    @JCat battery solution is very cost effective IMO. On the other hand sending it to Stroz and Bickel will get you the newest firmware update with your new battery. Still $129 is pretty spendy. My :2c:

    It will probably be hard to believe, but part of Germany's economic success, especially within the Euro zone, is our extreme low wage level. A skilled technician gets a comparably shitty salary. I guess Techies at S&B USA earn better than those in Germany. But still.. that's > 50% more than here. Dayum... You don't pay an extra 50 perce on Beamers and Benzes, do you?

    This post made me finally connect my Crafty to the phone and check out the firmware. It's 2.11. I guess the stock in the US must not be going as fast.

    Hm, I got my Crafty from a quite popular german reseller and the Crafty are one of their better selling units, my FW is 2,1ish. No idea what this has to say.
