The magnets would get wiped sideways as the head and tube are screwed together

I gave my Dad a Q8 for his 89th birthday, you should have seen him “beaming” when he fired it up in Turbo outside. Big Smile

He and Mom both want to punch,punch,punch the switch button, they may end up with it in configuration mode or things changed, but hopefully he’ll get the hang of it. He’ll be taking it tomorrow to their weekly game day and showing it off. Wink

Edit: Probably worthy to note, Dad grew up poor in the mountains of Virginia. He remembers the only light they had at night was a carbide lantern. (other than a candle or torch, of course) The little carbide pellets reacted with water and gave a gas that would power the light, and they wore this on their head! Yikes! Wink

I took my Q8 for a walk. Incredible light.
Thanks to all involved. And thanks to all BLF. Smile

When I was a child my father brought a carbide lantern from work. I was pretty impressed by the brightness of this light.

Great, now I’m on ebay looking at carbide lamp prices because it would be cool to buy one and have it around in case the power goes out. Sick

If you get a carbide lamp, make sure to get a maintenance kit with it.
Here’s one supplier: http://www.4bobandbob.com/pages/01.html

Here’s the caves.org page on carbide lamps, a good resource:

You want spare “tips” (brass and ceramic with a pinhole for the gas, press fit into the gas delivery tube, easily blown out and lost)
And a wing nut that holds the reflector onto the gas delivery tube; backing the wing nut off pulls the tip out if it’s properly been pressed in.
and a tip cleaner (a little bristle-wire brush useful for cleaning out the pinhole when it gets sooted up)
and spare felts (the gas is evolved in the lower container as water drips in; the felt is held onto the water drip delivery tube by a spring clip, and the gas has to move through the felt and a perforated plate to get into the gas delivery tube that goes up and turns 90 degrees to exit (through the tip) and burn at the focus point of the reflector.
When the water gets low, gas can start to back up from the fuel chamber into the upper water chamber through the water delivery tube; if you hear it bubbling, expect a small explosion to be possible, dumping a cup of water down over your face.
(Hey, strapping lights to one’s forehead has always had some hazards.)
And flints. Don’t forget the flints to strike a spark.
And a trash bottle to collect the white lime, you don’t want to be dumping that crap in a cave or anywhere else. Neutralize it properly:
https://www.google.com/search?q=calcium+hydrdoxide+disposal
(Hey, old lithium-ion batteries are a disposal issue too…)

You hold your palm over the reflector, capture some gas behind it, whip your hand off to the side turning the sparker and POP the lamp is lit with a nice flame that hovers in the air a fraction of an inch away from the tip orifice.

There are also 2-hole acetylene burner tips where the flame burns at the point the 2 jets of acetylene intersect in front of the reflector.

If you got it wrong, after the POP your tip has gone for a short flight and you have an unfocused orange flame sooting up your reflector (if the gas stayed lit).

Felts get clogged with the reaction product (calcium hydroxide, a white powder); replace them in the field, wash them out and dry the clogged ones later).

> tint

Very warm white at low gas pressure (short flame that deposits a lot of soot)
Neutral to blue-white at high gas pressure (better combustion in a longer flame)

PS, for those who like parts, the supplier listed above has these:

“4” Parabolic stainless steel reflector $15.50

Why would you charge a Q8 with a battery bank instead of just putting the batteries IN the Q8?  The only reason I could see is if you needed uninterrupted long-run time.  This for example can make sense for some bicycle gadgets (camera for example) for long rides if you don't want to get off the bike and stop to change batteries.  

 

I doubt you'll get much over 50% efficiency with an inductive charger off a battery bank.  So that's twice the battery weight, twice the cost, plus the weight cost, and bulk of holder and inductive charger, instead of... just carrying batteries.

Yeah, I thought it would be cool to have, but I’m over it. Lol

Yup, that’s the one. It has been used against free software a lot, and recently has gotten much more common in other contexts too. I find I have very little patience for it.

Anyway, my Q8 has been a nice night light and development host, and the batteries seem they’ll last a rather long time per charge. I’m only down to 3.9V on the first charge so far, and it gets used a lot.

Not sure I understand… the green switch led’s are supposed to be on when the light is off. Is that it? And the switch led’s go off when the light is on.

That is normal.
It can be used as a locator of the flashlight.

Normal operation of the Q8 has the switch led’s stay lit when the Q8 is turned off. However, if you are using ramping mode there is a simple way to get the switch led’s to remain off when the light is turned off. I am not sure if this can be done with the Q8 set to discrete, non ramping, modes.

Turn on the light. Then ramp up or down and then very quickly click the switch to turn off the light. When done quick enough the light turns off and the switch led’s stay off too.

That might take some practice but I can now make the switch led’s remain off whenever I want.

I hope that helps you.

That is normal. I think it was said it will last for years with the indicator lit.If you would like to turn it off, do 4 short clicks. That locks it out, and you have to do 4 short clicks to turn it back on. I think there is somewhere in the configuration to turn it off, permanently.

When your second Q8 is shut off the switch led’s do not come on? Do the switch led’s blink twice after you have the cells and screwed the body into the head? They are supposed to blink twice when the cells are first connected.

Also do the switch led’s blink if you do a battery check. (Click the switch three times quickly. The led’s at the switch should blink out the voltage. (Like 3 blinks,a pause and then 8 blinks for partially depleted cells; 4 blinks and a pause then 2 blinks for fully charged cells.) The main illumination led’s will also blink. Does that make the switch led’s blink?

Yes, led’s do not come on. Yes switch led’s blink twice. Voltage: First Q8 – 3 and 9, Second Q8 – 3 and 5 blinks.

It appears that the indicator led is turned off. Everything else appears to be working, and the indicator leds do work. Download the NarsilM Reference.pdf , look at the bottom under Advanced Configuration UI Operation It will tell you how to enable/disable the indicator led.
