Motorcycle Waterproof Display Screen with Android system

 From a boat utuber, it seems motor cycle android system is a pretty good solution for boater. some of them comes with android system 12-14, it means we can install apps we need.





most of them are made in china, their map system is very different from others, so I turn to Aliexpress, their android system is the same as westen ones.






This "EKIY M21 7 inch"

it's water prppf at IP67, brightness is about 800 nit, with built in gps, and android 13.

You can find some newer ones with larger screen and better function, I got this one with 71USD, and 3.2USD for shipping to TW, pretty good cost.

shipping was very quick,

package is light, no info about maker, no web site

including gps antenna, power adapter is 12-24V in and 5V out
with 3pins connector
power: Yellow is the battery +, the red one is for key swiched power.

This is the voltage measurement on the connector
GND is direct connected to input GND(as most bulk converter)
yellow is 5V, the upper 5V I guess: Is pull up to 5V for start up.
since it will only boot up if you supply power to red line



This is the power status when started.


It boot up with nice speed, not fast, but nor slow.
The touch screen works pretty smooth, some how better than my google phone.





comes with gps tester app I used to.

There is also a USB C and sd slot in the bottom, but with cover screwed on.

Next is to see what is the lux status under sun light.

I wish to turn this device to a portable device, but I don't really want to cut the power connector, the closest connector in TW is a so called M8 3 pins connector.

it does fit, but there is no screw on it, slight modification, can got it work.


as for power I use a PD 5V stuff, in order to power the unit with PD power bank.
and add a switch on the acc wire.

3D print case and Sealed with silcon




GPS antenna is too long, so I open it up to get it shorter.



before seal it up, first test if the reception is good or not...

There is a slot on the top side, so I 3d printed a adjustable frame for GPS

Arrange as this way

works fine, and easy holding, this could serve as my out door display
for drone stuff or IOT stuff.

Meshtastic 03 adding GPS on TTGO lora32 V2

圖片
 I wish to add GPS on my running meshtastic client on TTGO lora32. I have a GPS module outputs with nema at 9600bps. In the config app, in the position sector, you  can find the redefine of PGS pins. I firstly use IO00 as GPS_RX_pin. But it does not work. I guess the web config use 0 as none-config default. Then I want to know what is the default pin for GPS in meshtastic for TTGO Lora 32, I use the 2.4.x firmware for V2.1-1.6. Checked the git, there is no default gps pin for this hardware, so I changed the gps to mcu pin to 34, leave other pins stuff as 0 and do the config .  And it works. there is a new flasher, which still has LILYGO T-Lora V2.1-1.6 as board selection, with latest 2.5.xx firmware maintain 34,0,0 setting is no longer working. after few try, I decided to set to 34/32/25, where 32/25 are free pin on my board. I also reference to  LILYGO Meshtastic T-Beam V1.2 ESP32 LoRaGPS WiFi , it has a gps on 34/12 with 34/12/0 the setting is still working

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The...

GeoSetter how to add geotag on to pictures, and export to google earth as kmz

圖片
I use gps info of my cell phone when I take pictures, so that I can find where these pics were taken after a long voyage. I also wish to export these pics to google earth or google map, which can be kml or kmz. https://geosetter.de/en/download-en/ Geo setter is a very powerful one. Some times my phone was not able to add geotag info on the the picture, since it does not have location info at that time(indoor picture or gps was not available). Of course you can edit the pic, but geo sitter provide a better interface, you can pic a location on map and then assign the location to the photo that you selected. much easier than deal with coordinates. I notes the steps as following. After install geosetter, select the folder where you store your images. photos with a blue location dot means these pics contain geotag. select one pic with no blue dot, and go to top menu "map", select "show overview map"  a google map will show up with goe location of pictures...
