We have heard issues of DQG Tiny 18650 not being about to work despite using all types of 18650 batteries. I have pulled out the pill and tried to connect using direct wires to the two positions as indicated, without any success. I hope someone could find a way how to light up the pill by indicating his proposed suggestions here.
For info, i tried the touching the -ve part all around the aluminium portion, but to no avail. Let’s try to work out things and help Ric to understand the issues so that he can remedy the future batches.
Outer ring is the ground location…is it firmly touching the battery tube when you screw it in…if it doesn’t have positive contact, well no ground = no light, bad/loose ground = light acting all weird and flashing and whatnot
I had an issue with the SRK driver that Mattaus came up with…stock board is 2mm thick, OSHPark board is 1.6mm thick, might need to solder blob some “feet” on top and bottom of outer ring to thicken the electrical contact and see if that helps
When you said outer ring, do you mean the gold part or silver? I have tried touching all the silver part without any success. Didn’t try the gold as I was afraid it might short the board.
I don’t think it’s loose. But I’m out of house now and can only test it later. It worked the first time I received the light, but couldnt fire it up subsequently.
This is a known issue with this torch, hence I appreciate all those who have this light to assist.
Hi the gold ring with groups of three holes in it are battery - ground. The silver pill is not connected to anything electrically so can’t be used as a connection. Getting the pill tightened sufficiently to make good contact is actually quite difficult as theres so little metal to hold.
As mentioned by Warhawk, indeed the gold ring is the ground (-ve). However, it is a very bad ground, as even when i connect directly (i.e. use a testpen), it works intermittently.
The bad grounding extends to the entire body, which explains why alot of these torches failed. Either one takes off the pill and customise from scratch, or, in a nonchalant way, throw this torch away.
Kind of! I’ve been really busy and have not spent much time on it. I’ve tried all my various size optics and none of them fit properly |(
It must be a custom optic not just some generic brand like I assumed it would be. The driver is quite interesting proper constant current in a really small size and good regulation it seems to use separate resistors for each mode which are switched to a 7137 which I cannot find anywhere. . I put it back together and used it as a mule but that is no use to me so put it back in the box. Maybe I should contact Ric(?) and ask if he can get me a new optic?
Regards .
If you must, why not throw it my way? IDK where you are (no contact info in public, please), but postage couldn’t be that bad.
OTOH, just to be helpful, if you’d cover postage & parts if needed, I’d fix it for you and document the process & post it here, then mail it back. The benefit to me is I get to see how it’s made & don’t have to risk buying one to know if I’ll like it or not. I soldered my first joint before I was 10, so it’s not like the work is too hard.
