Today I painted and finalized the signal, Thebox, the signal is mounted on, contains the ESP8266 and the power supply unit, coming from the tracks. So it getting very compact and easy to connect.

Would I do something better next time? Of cause! There is always room for improvements. I would take 5mm LED’s instead of 3mm in diameter. I also would take brighter LED’s, because its hard to see the LED’s during daytime. I also would take finished U-profiles made of brass and would not try it on my own.

On the other hand side: its a prototype and I just wanted to see, if it is possible to make this idea become true.
