Hi
Is there any way for you to build a circuit where your current switch from plus to minus after a certain amount of time.

H-bridge, and either have another circuit control the interval of when the mosfets are active or have a micro-controller do it.

I know bro, but that is sadly not an option in this project.

You need to make clear what you mean when you say switch sign from + to -... Do you mean +5v to - 5v or +5v to 0v. these are not the same.
