Order was placed Oct 21 2017, and my tracking number is in that format. I’ve followed it since it shipped, and the last update on 17track says: “2017-10-25 12:46 Origin Post is Preparing Shipment, We have received notice that the originating post is preparing to dispatch this mail piece.” USPS tracking says it’s “Pre-shipment” and they haven’t received anything.
Really disappointed. Have requested refund, but hope the package does show up, as I’m more than willing to pay for it. :’(
Just an observation for Banggood preorder for the Q8 at this time. If I use the BG app (I’m using Android), the pre-order price for the BLF Q8 is $47.50. Cannot use any coupons or points. But if I use computer web browser, the price is $79.95, but I can use the ‘M4DQ8’ code, which brings down the price to $46.50. So it’s $1 cheaper on the computer web browser with code. I don’t see an “App only” indication so I’m not sure why this is so.
Hi guys,
Did a nasty mistake and i fried my Q8’s springs. I put one battery in reverse and it completly toasted my springs. Now they are mushy and batteries don’t even make contact with the brass ring. Do you know where i could find a replacement back pcb with springs?
Thx in advance.
Mine did the same thing… it just sat somewhere for over two weeks & then all of a sudden Tracking showed it was in New York City with the USPS.
Most likely yours will be along shortly…….
I'm working on a slighter better version, 3D printed as well. Maybe take a couple more days. I printed this one though, it needed some trimming to fit the outer ring, but tested well with a variety of cells: 30Q BT, GA flats, solder top cells, etc. I suggested it for the next batch of Q8's, but The Miller did not respond on it, and has not suggested it to ThorFire on the follow up, so I assume it's a dead issue with ThorFire.
All you have to do is replace the springs - no need to replace the PCB. The springs did their job, acting as a fuse.
It's been posted several times. On batch 2 lights, the center reflector screw is M4 x 10 mm, and the 2 side screws are M2.5 x 10 mm.
Miller, would you point out to Thorfire that it’s traditional in most countries to sell replacement parts for products* that may blow parts up, like fuses?
Except of course for microwave ovens and computers, which usually go into the landfill once a fuse blows (sigh).
Would you please ask TF to consider the company they want to keep, and to make the replacement parts available on an ongoing basis.
In this case either the springs, or populated tail PCBs, would be appropriate to have available.
(That way we may get the benefit of improvements in design over time as well, or so I can hope since you mentioned they’re looking to source better springs …. )
They could, I’d speculate, easily charge $10 for a replacement tail PCB and make money on the deal from early adopters who get a bit careless or want a spare to modify.
I don't know how you can do polarity protection on the battery. You can put it on the mcu, and I guess it's there, but diodes eat voltage. I would think you'd need active circuitry with FET on each battery, or some kind of piece of metal that gets hot and melts, oh wait, yeah, that worked.
You are missing the point. This is about two cells or more put in opposite ways around, into a 4P torch. Consequently creating the most massive double-voltage short.
You can protect against it it mechanically, with a simple plastic disc, that allows positive button-tops to contact, but blocks their flat negative bases.
It is already there, for the circuitry. A diode to protect the MCU. The FET and 7135 have to look after themselves, which they do. Surely you are familiar with the schematic by now ? And no, it eats no voltage from the main LED.
That would be the springs (assuming not bypassed). A real problem to fix for most.
