At this rate you will surpass myself in the most TA drivers built lol.

The latest drivers do look much better, you don’t need much paste at all. This is why the stencils are so nice, they give you the perfect amount and put it in the perfect spot every time and in a a couple of seconds too boot!

A tip for better reflowing is to reflow the top side components first and heat the pcb from the bottom with about ~350-380c air. First off this lets you use much higher air speeds without blowing components off and it also ensures the best possible connection.

The 7135 side just do like normal from the top of the components. They are much easier to deal with like this.

With lots of happy on lookers.

Wooo Hoooo!

Those shorts are almost always a result of too much solder paste. This is why I recommended the stincles. They make it much easier to get the right amount but not too much.

This is a case where less is more.

The mask looks good, the solder looks to have been pushed up from the FET having too much paste.

Generally if you replace the 7135 and reflow it back on it will work fine as that removed a little bit of solder paste when you do that.

Lexel, can you explain what “tactical” means on your spread sheet?

Also, on the drivers with resistors added for LEDs, can you explain the difference between indicator LED and lighted side switch LED?

Thanks

I still haven’t decided which version of Narsil to go with.

this is now the 3. board witch such an issue
not enough solder mask paint, and I get ground short from back of one AMC7135
costed me 1.5 hours so far

board looks messy when you unsolder those AMCs too often

Sorry for the setbacks. I hope you’re having some fun putting these together. I can tell your very organized. I’m sure that has helped make it much less frustrating.

I’m looking forward to having four more lights unified, all running Narsil.

I appreciate the work You, Texas_Ace, TomE and others have done to make these possible.

tactical means if you got a tailswitch the light always get in turbo as you turn the power on
there are 3 settings atm for start up, 2 blinks with low mode, turbo and no light

indicator LED blinks out what you configured it in UI settings

lighted sideswitch just lights the switch as soon as you connect the battery with tailswitch, but it has parasitic drain and can overdischarge batteries

Thanks

v1.2 has no temperature protection, so if thats Ok for you

Plus, I’ve recently switched to unprotected Liitokalas for more output so the LVP is more important to me even though I’ll have the lighted side switch to tell me if the rear switch is on or off.

These do look great. Thank you for making these for the community.

Thanks for all your hard work. I’m looking forward to receiving them and building me some awesome lights.

I posted this in TA's driver thread as well:

So made some  progress on merging Narsil 2 channel and 3 channel, so I have one source code base now with a header file called setups.h. In setups.h, you define all the board configuration settings and other compile time user option settings.

It's compiling now for 2 channel and 3 channel, with indicator LED enabled or disabled, and using R1/R2 or internal V1.1 ref for voltage monitoring.

Totally untested, but it compiles. 

Next to do is actually try it...

Some Details:

It has the more advanced, simplified version of the configuration settings UI that's in the 2 channel latest version of Narsil, v1.3. One new feature is ability to set the temperature threshold for thermal stepdown. There's probably a couple more tweaks as well in LVP and thermal stepdown, results from more recent testing.

Testing will take some time - may need to actually build up a couple boards, etc.

Thank you Lexel. You have been epic!!

Thank you Lexel once again, your work is truly appreciated !
Can I add a Locator LED if I want to ? Thanks !

Just little more Narsil update news -

• no further progress yet - project juggling 
• looks like the new BLF GT buck driver that's in the design/proto phase will be a perfect fit for this combined Narsil version - I'm calling it NarsilM for now: Multi-channel configuration
• the GT buck driver will just be another channel configuration, but with some special needs. Two I/O PWM pins, but slightly different behavior
• I'm a big fan of the TA triple drivers, so I want/need to get this done!! (as I hit myself over the head...)

locator LED with resistor can be simply added to the bleeder resistor pads

You will need to add a resistor inline with the LED in this case or it will drain the battery very quickly. A normal through hole resistor could be used easy enough. Something around 30k-50k ohms generally works out ok.
