Okay, while I'm quite proficient in micro-electronics, I'll agree this is a very sensitive subject both from a safety perspective, as well as apparently, a technical capability perspective. I've...

I've got some extra micro controllers and buttons I wanted to add to my saber to allow me some other user inputs to do things like configure the blade color or potentially some other function I dream...

As I mentioned, this battery charging circuit and IC was designed to charge batteries while under load. It has constant current and constant voltage modes that ensure the battery is handled properly....

I know it was best practice a while ago, because most circuits on the load side weren't designed to handle a wide range of inputs, so couldn't tolerate the charging voltage delivered by a charger....

Well, I talked to the folks at Adafruit and they said it shouldn't be a problem, unless you run into the issue of too much current through the traces, or pull more current than the battery + charging...

Their new USB-C one. 4410 I think is the product ID. It has the advantage that the VBat is in parallel with the charging circuit, so you should be able to pull the max current of the battery without...

Well, I've dug through the datasheets on the part used, and I can't find any mention of a max throughput current for the part. The functional block diagram of the part has a couple resistors in the...

Hmm. Okay, this is the kind of thing I need to know. Thanks a bunch. I'll need to figure out how this is handled.

Any idea what a typical amperage for the LED loads are? I know some are around 3A...

Agreed, it would simply be a more universal charging port. IE, I don't want to have to find a special lightsaber charger, would be nice to just plug it into a USB port somewhere. Those are...

I'm starting to gather some pieces and build various portions of a saber and would like to make it as modern, from an electronics perspective, as possible. I've got one set of electronics built and...
