I'm not an EE; I'm a software engineer. I want to build a mobile robotics platform. Here is the question- very simply, I'd like to have one power supply, something like a 7.5v pack of six rechargeable AA batteries.
Let's say that the components are
1) Two 7.5v DC motors
2) One 5~6v motor controller
3) 5v Arduino
4) 5v Raspberry Pi
Is there any way to engineer this so that all components are powered by the same 7.5v pack? A quick google search suggests that the parts required would add up to less than a value meal, I just have no idea how to do it.
What about a 12v rechargeable battery? They are easily obtainable by searching recycle ads for discarded children's toys, and six AAs won't last very long powering an Arduino + Raspberry Pi simultaneously.
Thanks in advance
