Just wanted to edit my post but somehow I find the editing function no longer. Instead of "cultivation" it should of course be called "annex" above. This is what you get when you write a text in English using some German words and have them translated automatically.😅😜🤣

I spent yesterday adding LED lights to Colwick station. The first job was to add red lights at the buffer stops. Sorry its a bit dark. The baseboard was upside down at this point. The next job was to add lights above the platforms. I bought some indoor tree lights that have solid core enamelled wire which worked out at about 6p per LED. They are wired in parallel. This means it is very easy to cut individual LEDs off the run with two 10cm wires connected. I rewired them into series and bent the wires to the profile of my station wall. I then came across a problem which took some time to get my head around. Once I had a series of 8 wired up they no longer light up. I tested all the solder joins and they were good. Eventually the penny dropped when I notice that I could light a run of 4 but not 5. Light Emitting Diodes still have the properties of a regular diode. They only pass current in one direct and have voltage drop across them. Diodes were literally my first lecture in my electronics degree. It turns out that with these LEDs the voltage drop is around 3v. My test 12volt supply would power 4 in series but not 5. I'm using my DCC track power at 16 volts so I can stretch to 5 in series. This made wiring more complex. I needed to feed from the middle as well as the ends. My platform construction technique came to my rescue. I use electric cable conduit as the base. This allowed me to pull the top of my platforms off and run the cable though the conduit. I still need to hide a couple of the riser wires, but all the wiring at high level will be exposed as it so often is on the prototype. The light fittings are screw caps which I've trimmed and glued to the wall. I need to repeat this for the other external wall. Then work out a similar system for a run along the middle of the station.
