First of all, a few important notes that you should definitely pay attention to.

3 kW electric drive for a 25-person sailing boat Make 25 (all pictures from www.linguini.eu)

PePeSail from the sailing forum approached us and pointed out his DIY project for installing an electric drive in a 25-foot sailing boat, whether we should publish it here. In the project, a built-in diesel was exchanged for a 3 kW electric drive.… Continue reading

Caused by the corona crisis, many sailors could not use sanitary facilities and access clean water for showering or washing dishes. It was created in a Discussion in the sailing forum from PePeSail a solution for the water treatment of surface fresh water as found in inland areas in lakes or rivers. On the homepage www.linguini.eu he introduced the system in more detail.… Continue reading

• Restart 08/2018
• other Projects
• Standby since 09/2019
• currently no further activities, as problems of the sensor calibration have not been solved satisfactorily
• current approach distribution:
  • AHRS 9-axis digital sensor (compass, gyro, acceleration sensor)
  • ESP32 controller unit (possibly a combination of fuzzy control / classic control algorithms)
  • Actuator industrial linear unit
• Status: Tests on the position sensor AHRS (Altitude and Heading Reference Sensor)
• Most projects are still in the concept development phase
• There are currently three projects working on the topic:

The on-board controller monitors and controls the energy system of a yacht

Development goals

• Increase in operational safety
• Increase in the battery life
• Fast charging of the batteries

Increase in operational safety

By displaying the accumulator states, the operator is informed at all times about the availability of the accumulator system. An age-related defect in the accumulator can be diagnosed by a constant decrease in capacity, so replacing the accumulator should be planned in good time.… Continue reading

First of all, a few important notes that you should definitely pay attention to.

• OpenSource Seatalk radio remote control for Raymarine autopilots
• Basis: Arduino ProMicro and 433MHz radio module
• Simple 433MHz 4-channel radio transmitter can be used
• Plus / minus 1 and plus / minus 10 degree steps
• Can also be combined with an OLED display (e.g. for wind display)
• Simple solderability through the use of conventional components in through-hole technology
• Programming with Arduino IDE
• Costs (board and components): approx.

First of all, a few important notes that you should definitely pay attention to.
