- with a handful of circuit boards, a little easy soldering, and some simple woodwork, you can make this usb-charged amplifier.
and yours will be even easier bc you won't mess up the amplifier the first two times like me! - Věda a technologie
Great info. Thanks
cool, it would take a few days to charge of that low current wouldnt it? assuming the wall brick is around 5v 1-3a only?
Good observation. Let's look up the specs, make an estimate and test it out.
I am in the middle of planning my own build and I have just about all the components that you do which is good news. I am hoping to make my build just a little less complex so I do have a question... Instead of using the voltage converter, would I be able to simply use a 12v AC adapter that plugs into the wall? Are those 12v that I would be getting (most likely just under 12v) enough to charge the battery module or does it have to be past 12v like you had set it?
Great video, thanks again. Hope to hear from you :)
That's a great question! I'll try it out with a variable power supply and let you know!
Glad I found you. At least I understand what some of the stuff I have is for. LOL. Listen... I have two of those LBB-3s that I want to hook up in series, using an optocoupler relay, to give me 24V for the Partsxpress blastbox kit. It's an optocoupler from HiLetgo that I bought from Amazon. But I'm stuck trying to figure out how to wire it up. I don't know shit about electronics. Care to help?
