*BLF LT1 Lantern Project) (updated Nov,17,2020)

Yeah, it needs the +/- labels swapped so it’s common positive instead of common negative.

Generally BAT+ goes directly to LED+ with nothing in its way, while BAT- goes through fancy stuff on the driver before becoming two LED- connections.

The Astrolux S41 did it backward initially, and they had to change it. For a while they were putting LEDs on backward while they went through their old stock of backward MCPCBs, but that was still better than having the battery short directly to itself.

good to know. I will change the positive to Negatives then.

Common negative? I am surprised based upon how all of the other drivers are designed

This is how I would do it as well, it is less wires to run and they would go to the same place anyways.

Right, and everything I learned so far with these things (which is still a looong way to go) is they are regulated on the negative side. I would have thought common positive.

Yes, you are correct, I figured they must be using a buck driver with V+ regulation or something. I just happened to get a notification yesterday for this thread and popped in. I know nothing about this project at all.

Thanks, DBSAR. It’s great to see the lantern and hear about it on video. Nice work!

[goshdogit]

The video nicely illustrates your design considerations. :+1: Looking forward to part two.

Seeing your prototype in video form has me even more excited about this project.

Thank you DBSAR for the Video and the informations!
And your Canadian accent is ok. I understand the most of all :+1:
