I apologise in advance for the long post, this is my experience with the TinyMight, I have taken this thing apart many times to fix issues.
I am by no means advising that anyone takes the device apart like I have, I initially did it with no advise from the manufacturer and could have caused more harm than good.
So after what I feel like has been a relatively long road. I think I have finally found myself with a TinyMight working as good as it did when I first received the unit.
Short story: I bought the TinyMight last year from Vapefiend on their first or second stok drop. I love the TinyMight and I am using it extensively everyday as it is my daily driver.
Problems for me first occured when the haptic feedback started to be a bit off, not triggering everytime I used the vape. I then dropped the TinyMight once or twice in the first couple of months of using it onto a wooden floor, it fell in a way that the battery contact strip in the bottom of the battery compartment was bent and the battery now sat too far into the compartment... no contact. No Power.
So my first, of many, teardowns involved me taking the whole thing apart except for the heater which I left alone. I unscrewed the circuit board on the bottom of the unit and bent the contact strip back up to a point where the batteries made contact.
All good, except for the haptic and the heater maybe had a bit of fluctution to it, still working mostly to the original usage. Over that initial period after my first teardown, I had to take it apart a couple of times in which I somehow managed to fix the haptic feedback issues. I think the motor had becoming mildly dislodged within the unit when I had dropped it. I moved it back into place, problem solved.
For the most part it was back to normal, until around December last year when I noticed a considerable output drop and the inability to finish bowls anywhere close to the amount I was before, after a few weeks of issues and the coming festive period I felt I had to take some action once more.
I found that I had to take it apart again, and the next couple of months up until this point I have taken it apart somewhere in the double digits between 30/50 times. In this time, I've come to understand the conduction properties of the unit, and how the circuit completes. For me, I found my biggest issue was a contact issue, I came to find this was actually within the heater housing. I was reluctant to actually take the heater out of the glass housing it sits in. I continued to take apart and midly readjust the heater each time the output would drop and then it would work again properly for a short while before dropping.
I decided to contact TinyMight, I explained my situation in as much detail as I could. I also explained my reluctance to send overseas due to the new Brexit rules and export/import costs that could arise from that. A brief email exchange, with me explaining how I believe it to be a contact issue within the heater. I was told I could readjust the heating element to create better contact, or at least I read it as that... I wasn't given huge details on what would happen if I were to take the heater out of the glass housing. But I went ahead with the task.
I came across a bit of an issue as I took the heating coil out of the glass housing. It begun to uncoil/unwrap, funnily enough... So the next 15 or so minutes I was having trouble getting the coil wrapped around and lined up with the 4 struts that hold it all together. Essentially there are these small holes places along the coil, and they all need to be lined up and then kept in place while the rest is lined up. It was an arduous process that tested my patience extremely. I nearly gave up, decided to wrap the lining metal coil that holds the heater and creates contact instead. I went back to the heater coil, and I managed to get everything lined up (a lesson to some that sometimes you just need to do something else and come back to it).
For me the next moment, me putting it all back together and turning it on was a big one. I was about ready to give up and send the unit overseas and incur whatever costs... But I think I may have done it. I'm getting decent flavoured clouds off of setting 6 (my previous golden number), bumping up to 7.5 to get a thicker cloud without too much top layer heat singe. Pushing up to 8.5 to completely finish a bowl. I'm in a happy place again after at least half a year of me tinkering and playing. I truly hope that I have fixed the issues completely. But I feel pretty confident if I were to have to take it apart again. I'm lucky to have a little bit of an engineering mindset to a certain degree, which I've no doubt helped me as I have hardly a huge amount of experience playing with electronics.
That is my journey with the TinyMight, it is a great vape that I have tediously kept attempting to bring back to full function again. I think I've done that and I and thankful to have the vape back to its former glory, and I hope that remains to be the case.
I will once again advise people against tinkering to the degree that I have, unless you absolutely have to... in which case I would definitely send TinyMight an email (few day wait, but you do get a response). I came to find that my vape still functioned during the issues, I came to find it was a contact issue and that the fluctuating output meant that it still had the ability to perform at full output. I slowly came to the conclusion I did after a long time of me taking it apart, but really trying not to do much other than slightly aligning something up better and hoping that would solve the issue. I would not advise anyone remove the metal heating coil from its glass housing. This was incredibly tedious. But I will state that if I didn't do these things, my TinyMight would be on it's way to another country... in which I am thankful for. Not all issues are the same though, what worked for me may not work for you. I would only advise attempting anything similar to what I attempted if you have no other resort, and to please try to talk it over with TinyMight first.
I hope this is of interest to anyone and maybe helps someone. But please don't take anything apart on my word alone. I do not want anyone to break their unit because of me.
Hope you all have a good day!
