Hi,
I'm new to this forum but I hope you guys can help me out. I'm working on a project for my school DT lessons and I need some help with the electronics. I am making a bedside device that has Bluetooth speakers, RGB LED lights and a charging hub. I would like to power all three with one 12v DC power supply (they all run on 12v apart from speakers which I can use a transformer to power it with 5v). I originally thought to run the three by splitting the PSU into three in parallel to maintain the voltage but then I realised the problem with amps. The LEDs need 2A the speaker needs 1A and I'm not sure what the car charger needs but it runs from a cigarette socket in a car and the output is 7.8A (not sure if this has some kind of built in amplifier or not). So this is where I need help how shall I do this. I am in the UK if that makes a difference for PSUs.
Any help appreciated,
Ollie
ps: here are the parts i was thinking of using
