New bracket for the case with a wall bracket to compensate for a wrong horizontal installation -> ThingiverseĪfter some testing I noticed that the sensor starts again from zero after a power loss (despite having saved the calibration). However, since the cover “pulls” itself completely over the lower housing, it no longer closes. Unfortunately, in the first version, I placed my brackets for the display and the touch surfaces flush with the upper edge of the case. The wiring can be in the Circuit diagram to be checked. Otherwise the Waveshare SN65HVD230 terminates the entire NMEA bus. The only thing to note when assembling is that the terminating resistor on the CAN module (Waveshare SN65HVD230) has to be broken out. I built the whole thing in a standard housing in which I built a base plate as a support for the perforated plate and the voltage converter. Magnetic course (after pressing T2, “…stored…” appears for 2 seconds) (Unfortunately, what these numbers mean exactly is not clear from the documentation of the CMPS14) The three details are each specified by the following numbers: Sensor system status followed by two numbers
The "autocalibration" mode is switched off It may have to be adjusted after field tests on board The HDM data was not switched off, as messages 0 occur very often. If the sensor is not fully calibrated (not all sensor responses are 1) “inaccurate” will appear. The sensor is currently being calibrated, which was triggered by touch 1&2. The display is divided into three areas: Left (in 90° rotated font) Operation is limited to the two touch surfaces (screws): touch surfaceĪutocalibration off Save performed calibration
This can be used to set a - horizontal - correction for a deviation of the compass line from the boat axis. A deviation table can be stored in it, which automatically corrects the given course for the respective courses.

variables in the code Complete source code The compass identifies itself on the bus as "Magnetix Alpha" and can also be found under that name in the network's sources. The ESP gets the data via the I2C bus, converts the whole thing into an NMEA2K data set (127250) and sends it to the network. A built-in plug from Techno-Spark is used to connect to the network. Power is supplied via the NMEA bus and is ~1LEN. Although the protocol between the CMPS and the ESP is a short range protocol (I2C), I have no problems with a cable length of ~70cm The connection between the compass sensor and the ESP is made via a KAT5 network cable, in which two cables are always connected to form a pair. The brackets for the OLED and the touch sensors (VA screws) were also created with a 3 printer. The housing for the electronics is a Bocube from "Both the bracket and the housing were 3D printed for the sensor. A 0.91 inch OLED with 132×32 pixels is used for the display in the housing. A CMPS14 serves as a basis as a sensor, an ESP32 as a calculator, a Waveshare SN65HVD230 (don't forget to break out the resistor) as a link to the bus and an LM2596 as a voltage converter. Magnetix is an electronic compass that transmits its data on the MNEA2k bus. The compass is ready, but not yet tested on the boat (status: 2022.01). Thanks to many tips in different forums, it was successful. The construction of the electronic compass with an output to the NMEA2000 network was inspired by a post by Andreas in the "" forum.

Due to the corona restrictions and the more free time being spent at home, the idea of building the compass myself came up. The disks identify all four magnets.I've always found the idea of not only showing the course on my plotter when the boat is moving, but also when it's bobbing along quietly, I've always found it exciting.Īfter searching the I-Net for different manufacturers, it quickly became clear that I might not need an e-compass on board at current prices. The triangles and squares identify the North-South polarity of one of their embedded magnets. Panel shapes include two types of interlocking triangles, interlockable squares, and circle or disks.
The bars with magnets at each end are 27 mm (1.1 in) long, or 68 mm (2.7 in), or 53 mm (2.1 in) and flexible, or short rigid curves. The spheres are 0.588 in (14.9 mm) to 0.593 in (15.1 mm) in diameter (larger than Geomag), approximately 27.8 g (0.98 oz) in weight, and are prone to surface corrosion, unlike most other magnetic construction toys. Designed to be a cheaper version of the Geomag magnetic construction set, Magnetix's image suffered severely when an early manufacturing defect caused a death, and was subsequently sold under several different brands after the defect was corrected. Magnetix is a magnetic construction toy consisting of a combination of plastic building pieces containing embedded neodymium magnets, and steel bearing balls that can be connected to form geometric shapes and structures.
