Sorry for the stupid question (I am newbie to this hobby) but… How to correctly inject the power? I don’t mean the power calculation but how to execute it? (with some pictures) Are there any designed connectors for that purpose or is it all DIY? Let’s say we have 3 5V strings (50 pixel/each). To connect them we would probably need to inject power between them (what I have read so far). Can anyone provide any pictures how to do it correctly? (in details) (The injection, wiring, the power source connection from a single DC source or multiple). Any info would be appreciated.
