Hello all,

Since I decided to use WiFi for the communication between transmitter and boat I now needed a WiFi router in the field. I found a nicely tiny and very efficient router and now needed to place it somewhere. It seems logical to put it on the water in a high place considering that this will increase the coverage of the network (along with the WiFi repeaters in both the transmitter and the boat), but this requires something to put it on. A lighthouse like the Fastnet Lighthouse south of Ireland is a perfect solution as it provides some 60cm of height above the water for the router, gives light during the night (off course the light will be working and rotating) and by adding an anchor winch which is remote controlled via an ESP32 board I can tow it to any location I want and not need to worry about water depth as well.

It took me 5 minutes to design anchor winch and 40 minutes later the 3D printer had finisht it as well. The engine and drum turned out to fit perfectly as well.

The winch works well and it powerful enough.

This will be the anchor making sure the lighthouse can not drift off by the wind. I made room for 2 layers of 4 blocks of lead meant for balancing car wheels. In the middle on the bottom I put a M4 threaded insert in which I will screw an eyebolt to connect the anchor chain or rope. By putting the threaded insert on the bottom it cannot be pulled out.

I made quite some headway with filling and sanding.

The bulbous bow requires quite some attention since it's not yet symmetrical.


The stern is a lot more symmetrical.

Took a pencil and a host of different types of rulers to check how close I am to the desired result, which turned out to be not as close as I thought.


After finalizing the design I printed the new power supply box. This is a lot better then what is currently in the old hull. The top plate housing a new 20x4 LCD screen and the plate holding the Raspberry Pi and it's attributes and a plate to hold all the removable plates straight are currently being printed. All plates will remain removable for maintaince purposes.
