In Germany we have them everywhere. When I look out the window I see at least 10 of them.

When I count up to 100 I’d be able to count much further. In practice I’d just use my phone or a dedicated GPS receiver.

They are recalling the H150 and will exchange them for a fixed version. It’s a huge financial loss, though. And I don’t want to be the engineer who caused this trouble.

Probably yes, if you were able to unscrew the head (they use very good glue). Also there are several other components at the battery side of the driver. Lastly there’s always the chance other components fall off from the heat, maybe at the back side.

So yes, it’s possible, but difficult. The good thing: You don’t have to worry about it, Skilhunt is recalling the H150 and will exchange them for a fixed version!

Practicality depends on your preference. It’s heavy, some people say it stinks. But scratches don’t make it look ugly and it ages nicely with time.

I guess tailcap current measurements with a DMM are good enough for my purposes.

Only as long as you use a clamp meter.

Reading a voltage would be possible (but the ADC code is already very complex and messy). Some types of drivers have a sense resistor already, but usually it is connected to an opamp and adding another load might cause visible fluctuations in the output.

So yes, it could be possible, but requires a driver redesign and lots of refactoring of Anduril.

It looks like a rebranded Yinding or Rayten LED that is already used for a while in other flashlights. It’s definitely not their own development or production.

As already mentioned, this is the post-off voltage display. Depending on your firmware version, its time can be changed from the battcheck menu. Set to 0 to turn it off.

The red flash is a bug that already got fixed (together with several other bugs). Do you have a flashing kit for updating the firmware?

I don’t have one, but I’m pretty sure it has a different driver. Never seen a Chinese flashlight engineer using an AVR microcontroller for their work.
