Hobbyist question, not a professional (that'll become very clear shortly).
I have some multi-floored Lego buildings that I'd like to light up the inside. Buildings are on 3 shelves laid out side by side with a potential of 10 per shelf (shelves are 10' wide).
- The LED strip lights (16.4') includes a power supply (I only know it's 12V and have contacted the seller for more details of the PS).
- I'd run the power from the PS to a main terminal block.
- The main terminal block would connect to a pair of subsequent terminal blocks (a pair located on each shelf - 1 for the positive leads and 1 for the negative leads - 6 total).
- Each terminal block has 8 terminals (not enough for 10 buildings per shelf but it's what I have on hand for now)
- I would be using 22AWG to connect the shelf terminal block to the building. There would be JST plug between the building and the shelf terminal block so the building could be easily disconnected for repairs/updates/etc.
- The connecting wire would enter the back of the building to the lower level
- If the building had additional levels, connecting wires would be attached to cut LED strips in series.
- Each level within a building would have a 3" section of LED strip.
- Am I missing anything?
I'm looking at buying an LED strip of lights (16.4' or 196.8"), cutting pieces off, and attaching them to the inside of the Lego buildings. Each strip would be connected using 22 AWG wiring. There would be JST connectors between the terminal blocks so the building could easily be removed for whatever reason. Terminal blocks are being used for tidiness primarily.
There are 23 buildings and around 65 levels in total but no more than 3 levels per building. I'd only need 3" sections for lighting for each level building (for a building with 3 levels, I'd be using a total of 9" of LED strip lights). I expect to use the entire LED strip.
Would my introducing of the multiple terminal blocks and JST plugs add too much resistance to the circuit that I would need to rethinking my layout and/or power supply?
What are some things I should consider (for safety) or am I overcomplicating this project?
