Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

Tried all the methods suggested by the good folks here with no luck. Pics of the second batch in the wild lead me to believe it shouldn’t be too long till ours show up.

Of my 3, one is being played with at the Hong Kong Airport and the good people in the Chinese postal community are testing my other two, prior to letting the Airport personnel have their go. :wink:

Nice. I don’t know if my similar looking case I had already forgotten about is the exact same(bought separately, don’t have the SC01), but it will actually fit two sets of spare cells packed in the Nitecore NBM40 holders. I’ll check if it also fits the Q8 with them later on, I left the Q8 in my car. :person_facepalming:

I got a 20 digit also tied up being sorted in HK for 2 days, and one 30 digit with no clue how to trace it, message left with BG bout it and no answer yet.

i doubt there will be any clue in packaging. From pics who recv'd the new ones, should be able to tell easily by the screws holding down the driver - 1st batch had flat heads, 2nd batch has round panheads - thinks that's what they are called. Screws seen under the tailcap were changed the same way.

Depends if the cell has a raise bottom or not
Samsung18650 cells have the heat shrink tube covering the minus if you don’t pus the calipers hard

Steel is not a good conductor so it wont harm too bad

It won’t probably be that dangerous, but not a pleasant surprise either. It’s easy to short a cell when trying to measure even if it’s wrapped around the edges on negative end.

Using some tape or a piece of flat plastic is quite easy with the digital caliper pictured above, even if you want to be super accurate. Just isolate the ends, zero, and measure.

Steel doesn’t conduct as well as copper, but those calipers are thick enough it’d be like the equivalent of a zero-gauge copper wire. It should easily be able to damage the cell if held like that for long.

If anyone thinks steel isn’t a good conductor, try laying a wrench across a car battery. :stuck_out_tongue: (or, actually, don’t… unless you want to destroy both items and risk injury)

In both of these scenarios you would see some sparks (sorry for my understatement) before cell damage would occur. I’m more afraid of second or third degree burns on hands and face, causing a domestic or industrial fire, and/or eye damage. Or avoiding any of those, publicly having to admit shitting oneself. Pardon my French on a family forum like this, but this is serious stuff. I’m speaking out of experience and it’s my wish others will not have to. :smiley:

Dr. Jones has bump protection working really good in his h17f driver. I’m not sure how he implemented it, but it can distinguishe whether loss of power was a bump or an intentional button press. A slam down on the table will be ignored.

The last time I was home, I showed my wife the Q8. She said, “Wow, that’s a NICE flashlight.”

As I type this, I’m in DC for business. She is in San Diego. We’re on the phone and a circuit breaker trips. As she’s heading outside to reset the breaker (with the L6) she says, “I need the soda can light.”

Across the country, I am grinning ear to ear.

I love my wife!

Quality cells like those Samsungs wont burn and explode
They got still electro-mechanical safeties against serious overcurrent or vent, which will separate the Anode from the positive contact

Those cell explosions usually come from overdischarge or other abuse damaging the separator foil inside the cell or overcharge

Yeah I ordered an $0,88 plastic caliper to measure cells or things that scratch easy. Good Quality 150 mm 6” Gray Plastic Mini Caliper Vernier Gauge Micrometer

Even cheaper now

Smittyjojo, yes it I’d frustrating, order and forget is rrally best for blood pressure.

Lots have been send out, too late for a V2 marking on box.

Yes, I probably shouldn’t understate either. Don’t short a car battery. Those things are often rated for 500+ Amps on a cold day, and in one test of a relatively small battery they measured 1700 A with a dead short. A larger battery sized for a truck could probably put out thousands of Amps. At 12V, that means tens of thousands of Watts, concentrated into a relatively small area, which can cause serious damage or even death.

I had a car battery explode on me once when I turned the ignition. Had the bonnet open (hood for those using corrupted English…) and bits of it landed a good 100 yards away. Quite spectacular but potentially bad for your underwear.

The simplicity makes it an awsome idea.

I love extra features we have these days but, when ity becomes so complex you need a tutorial.... that's a bit much.

I instantly thought of the shorting aspect of using metal calipers also when I saw the picture, but I just figured that the set up seen was just for the sake of the photo. Metal calipers could be used with an insulating spacer and then just subtract the thickness of the insulator from the measurement. The insulator could be as simple as a piece of card stock.

thanks the miller, i just ordered the ali plastic calipers. :slight_smile:

ken

Seems like you can use wax paper / baking paper as insulator too. I use it a lot in my micro to collect the fat and gravy when baking raw food.

GREAT! Even more tables.

Love it
