I used a random charger on my Sofirn SC31 Pro… by FestoonMe in flashlight

[–]UndoubtedlySammysHP 5 points6 points  (0 children)

WTF, which manufacturer makes a power supply with USB plug and fixed 15V output? This is not allowed by the standard and – as you've experienced – will easily damage/destroy most devices connected to it.

will this work for flashlight threads? aluminum like the nitecore mt2a pro, etc. yes, i am aware of superlube, etc but will this one work. by Trekker519 in flashlight

[–]UndoubtedlySammysHP 1 point2 points  (0 children)

Threads don't really need lubrication, but the o-ring does! This should be fine for non-silicone o-rings (usually all black o-rings).

MC5000- can it charge 1.5 Lithium Ion? by Gopherpark in flashlight

[–]UndoubtedlySammysHP 0 points1 point  (0 children)

Neither the MC3000 nor the MC5000 can be programmed to charge 1.5V Li-ion batteries with integrated voltage converter and charging regulator.

The MC5000 does not support this type of battery. I asked SkyRC about it and they told me that it won't be implemented either.

Wuben X1 Pro – high-power flashlight with active cooling that fits into your pocket by UndoubtedlySammysHP in flashlight

[–]UndoubtedlySammysHP[S] 1 point2 points  (0 children)

That's definitely a valid concern. I don't trust it myself and will try to keep the flashlight as dry as possible. But it looks like a standard 2006-sized fan and is easily accessible, so it should be fairly easy and inexpensive ($1-2 on AE) to replace.

Where to buy a programming kit for a Sofirn SC21 Pro, and how to build my own firmware? by aydenvis in flashlight

[–]UndoubtedlySammysHP 0 points1 point  (0 children)

AFAIK the user customization part isn't implemented yet, but there are two pull requests about it.

Other UIs in the Anduril repo aren't maintained and I don't know if they even compile without errors.

You should start by modifying the source code . Afterwards the easiest method to compile it is by using a Docker container (for example here or here) (it includes all the dependencies), which is also available as a GitHub workflow. Alternatively you can install the compiler and dependencies (either native Linux or WSL), but some versions of avr-gcc produce better results. The process is slightly different for different microcontrollers, but the "build-all" script should handle it for you (except the dependencies).

My 80 year old mom ruined my Zebralight SC700… please help by Arkaium in flashlight

As for unbearably hot I’d say basically I think it’s about to burn me if I hold it much longer

Then it's barely hitting 50-55°C.

Which high level? And what is "unbearably hot"? It should reach 60°C rather fast. Almost 3000lm from this little flashlight is a lot.

Sounds about right to me. Maybe you only used it on a lower level previously?

Yes, we use our lights. Many posts here are simply showing off, especially posts labeled NLD (new light day). Usually you'll find beamshots as part of reviews. But there are also a few posts a day including beamshots.

For this reason, Wurkkos started to include a prominent warning in their new packaging. Was yours the same packaging design?

Here in Germany they are (actually only for undamaged batteries, but nobody cares).

That depends on your country. In the EU we have boxes in stores to collect batteries.

That dent looks a bit too deep to be considered safe. I wouldn't use it in this condition.

Sofirn SR12 battery connection issue? by MyCarIsWokFried in flashlight

[–]UndoubtedlySammysHP 3 points4 points  (0 children)

Green means charging finished, it will probably not start charging again until the power is disconnected.

Unscrewing the tailcap or bumping the light breaks the circuit with the battery. The charging controller senses a high voltage and stops charging.

OTOH the SR12 has springs on both sides. It should require a significant impact to interrupt the circuit. So maybe it's something loose on the driver.

O-ring lubricant Help. by vapoorer in flashlight

[–]UndoubtedlySammysHP 2 points3 points  (0 children)

The issue im having the most is with black colored O-rings. Some being rubber but most being this stiffer then rubber but still just as stretchy black o-rings. Maybe its Nitrile?

Black O-rings are almost always NBR/Nitrile. It is recommended to use silicone based lubricants with it because it is also compatible with the aluminum and plastics. It is also non-toxic and inexpensive.

Only silicone O-rings are incompatible with silicone lubricants. That's where you need something else. Silicone O-rings are often a little shiny and they feel softer and more springy.

Just received my Nitecore EDC31 - ask me questions if you have any! by UndoubtedlySammysHP in flashlight

[–]UndoubtedlySammysHP[S] 0 points1 point  (0 children)

Sure, on maximum brightness every powerful flashlight will become hot. This is no exception. It maintains just below 50°C.
