making a small batch of Texas Avenger "TA" Drivers fully tested running Bistro or Narsil, Clicky or E-switch, SIR800

Input
100 AMC7135
3 17mm boards

Output first orders complete to get shipped

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

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.

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

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. :beer:

Okay, mine doesn’t say tactical on the spreadsheet, but it should.
Also, I only need the lighted side switch, so I think Narsil v1.2 is what I should go with. That way I also have the low votage protection.

Thanks

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

Tom E is too busy to make LVP / indicator switch into Narsil triple v1.5

Yes, that’s fine by me. My hand is the temperature protection. Lol

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.

sent today

reflowed now all boards
tomorrow doing a lot programming and testing

last chance to check if your divers are set up as you wish
when you did not specify any temperature limit it will be set to 60°C

all drivers are now flashed configured and tested
did pack em as well

last chance to check the Excel sheet if everything is right

:+1: Excellent!

Thanks for all your hard work. I’m looking forward to receiving them and building me some awesome lights. :+1:

+1 :beer:

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!! :+1:

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

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