Hi all,
I probably count myself as 1 step up from total novice, but I am a noob to these forums, so be gentle!
I'm looking to build a boombox, (I know... How original! :)) but I really want the power to work in a specific way. I've picked out an amp (a T2020 type thing) and what I think is a suitable battery (12v, 7Ah), and I'm happy and confident to connect it all up and make it work.
BUT, I also want my boombox to work from the mains, in much the same way a laptop does. (When it's not plugged in, it's powered from the battery. When it is plugged it works from the mains AND the battery is charging. And I want this to happen automatically, like it does in a laptop or a phone or whatever. No fiddling with charger terminals, no flicking of switches.) I've scratched my head until there's barely anything left there!! Help me please!
(Or just tell me it's a pipe dream and completely impossible!)
Thanks,
Jon
