回 高昂 & TDX:
This is the 電阻 I used. Because I use this bigger 電阻, at maximum 12V, I can connect 1 to 4 LEDs(@3V) in one serial circuit.

And in this kit, each serial circuit (an illustration to follow) I only have 3 LEDs, therefore, I can run either 9V or 12V batteris without problems. Very flexible, but the draw back is using this 電阻 waste energy... which is probably why I need 3x12V batteries.
This is where I hide the batteries. As I said before, I end up using 3 12V batteries...

In terms of wiring, I cut these pieces along the red line to make wiring easier.

This is how I grouped the LEDs. Each serial circuit must has a separate 電阻. Every serial circuit is then connected into one parallel circuit.

This is how I cover up the wire

And previous pictures have not shown these LEDs...just for record

之前冇影底 work in progress, 所以就咁分享吓.
