-====== Mole Beacon Light ======
+====== Mole Beacon ======
-===== Introduction =====
 {{ :project:maerklin:warnemuende:lighthouse:mole_beacon_light.png?200|}}
+===== Introduction =====
 For our Warnemünde section, which includes a water area, we also need a lighthouse so that our ships can travel safely.
-Since Warnemünde has two [[https://de.wikipedia.org/wiki/Molenfeuer_Warnem%C3%BCnde|Mole Beacon Lights]] (one green and one red), I decided to recreate the green beacon light. I did some research and found some good reference images for this project.

-First, I replicated the building in [[software:onshape:start|]]. This was not as easy as I initially thought, but in the end, I was successful.
+===== Source Code =====

+Everything can be found in the [[https://git.mars3142.dev/model-railway/warnemuende-lighthouses|git repository]].
-The more interesting part was the electronics. I used an [[hardware:esp32:start|]] as the controller and decided to connect it to the [[..:..:system_control:start|]] with my generic BLE system. Then, I tested if I could replicate the beacon signal (2 seconds on and 2 seconds off). It was the first time I had used hardware timers and interrupts for the LEDs. The beacon's LED will illuminate transparent PLA, making the light visible.
+This device will have three services: **0x180A** (device information services), **0xA000** (light service) and **0xA999** (settings service). Within the services will be specific characteristics, but I don't will describe it here in detail.
+If you need more information about the BLE communication visit the [[..:..:system_control:ble:start|]] page.

+The more interesting part was the electronics.

 A more challenging part will be the outdoor lights, as the building has two of them. I will try to use 0402 3V LEDs and hope that I can print a miniature enclosure to mimic the real lamps.

+===== KiCad =====
+The custom PCBs are created within [[software:kicad:start|]] and manufactured by the sponsor [[https://pcbway.com|PCBWay]].
+This is the LED board, with is located a the top within the building. Is has connections to the WS2812B RGB LED and the two outdoor 0402 LEDs, which are within separate housings.

+But the LED board can't work without any controller. Here it is.
