I'm going to made some projects in my double garage and therefore i thinking about to make an 12v "Distribution sentral" witch is a box with 10-15x outputs that i can use for powering arduino projects, maybe som roof lighting etc. Some ideas how i start regards to get enough power? Should i use an…

Only you can determine what enough power is! When you do that, then you can determine the current needed. Then you can determine the power loss in the wires you are using. Then you will know how much power/voltage you need at the power supply. Paul

Paul_KD7HB: Tips and tricks? I don't know why anyone would do what you are considering. If I need something other than 120VAC, I plug in an appropriate PSU. Paul Ok, but why is this not an good idea? If i over time will mount several micro controllers in garage, i then have an ready power for i…

12V is tricky as wire length causes much more significant voltage drop and there is a risk of fire. In general devices for domestic use that need 12v convert the ac close to the required use. I am rewiring a boat and the thickness of wire required is telling. Things that you could power in a house w…

First of all, as others have mentioned, you need define your power requirements. Based on that you can then size the power supply, cabling and also provide overcurrent protection with appropriately sized fuses. 12V DC is the standard voltage for CCTV cameras. You might consider something like THI…

I think maybe it is some misunderstanding here. I sed earlier that i already have 220V in the garage. The cable from 220V outlet to this box i talk about is maybe 1 meter (at the most). So instead of using several power adapter and use all my 220V outlets in garage, i think it's better to make one …

All my Arduino projects that I'm going to add using from 3.3 to 5 volt and have own circuits for voltage regulation. If you mean you will rely on the on board regulators then I suggest you change your design to include a 12V to 5V buck converter for each project, mounted close to the board that n…

Yes, that was my plan from start. I have a lot of buck and buck/boost convertes i can use.

Yes, i know that.

But is use of an power adapter the way to go, or is it better to place an 12v power supply in the garage?

Some random tips and tricks regards to the project is also welcome.
