Rechargeable Battery Pack Install Answered

I have a project that I have been working on, and it currently runs on two different battery packs for different components. I want to put rechargeable batteries in these packs, and I want to install a wall charger to charge the batteries. 
I am having trouble finding a good tutorial on the circuitry of this. 
Will I need two different chargers for the two components, or can I charge both from the same power supply? 
Can anyone help me out?

I can post some photos of the project and its current circuitry if needed, its a laser spirograph.

You need to be specific about the batteries you will be using.

NiCd, NiMH, Lithium? etc - they charge differently.

I could use anything I suppose, right now it is running on alkaline but I would obviously be replacing that. Could you recommend a type? For instance if one would be easier to build the circuitry for than the others?
