Voltlog #274 – Installing Traccar GPS Tracking Server On A Raspberry Pi

Welcome to a new Voltlog, today I’m gonna show you how to setup your own GPS tracking server on a raspberry pi. It doesn’t have to be a Raspberry pi, because the software that we’re going to be using for the tracking server is available for Windows and Linux as well, so you could host this on your windows machine or in a virtual machine on a cloud service, it’s up to you, but in this video I’m going to do it on a Raspberry pi 4.

The idea started a couple of videos back, in Voltlog #272 when I got this GPS tracker disguised into a general purpose automotive relay. In theory this should come with free online tracking service on some Chinese hosted server but I wasn’t able to connect to that server and so I thought why not setup my own server and try to pair it with this tracker. So if you want to learn more about this tracker, checkout Voltlog #272 linked on screen right now and then come back to watch this video.

First step is to setup a fresh install of Raspbian, latest version from the source. Next step is to setup the tracking server, the name of the software is Traccar and here is their website. We’re going to be using the Linux arm release, because the raspberry pi runs on an arm processor. Next, your raspberry pi is likely sitting behind a router or firewall so you will need to forward a port so an external device like a GPS tracker can connect to our newly created server.

Next we can add our GPS tracker in the web interface of Traccar, on the left side I click add, choose a name for your device and fill in the 10 digit identifier which is this label on the side of your trackers case.The newly created device will be shown as offline until the server starts receiving data.

The final step is to configure the GPS tracker and these particular commands apply to the tracker that I am using, you might have to use different commands for a different tracker but the idea is to reset the tracker, set your admin number, configure the APN settings for your network operator, set the external ip address we saved earlier, the port is 5013. Set the upload frequency in seconds and enable the GPRS connection. Going back to the Traccar web interface, status should switch to online and we should start seeing data about our device.

Voltlog #272 – Car Relay GPS Tracker Setup CJ720

In this video we’ll take a look at the CJ720 car relay gps tracker, I’ll show you how to setup the tracker and how to get position information. I will show you what kind of commands this tracker accepts and I will also do a teardown towards the end.

For information on how to setup your own GPS Tracking server, running on a raspberry pi, using open source software, checkout Voltlog #274.

Voltlog #263 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re going to start with this big jar of flux paste. This is commonly referred to as “yellow paste”, the branding I believe is NT but if you search for yellow paste you will find it in various sizes. Banggood sells it in 150 gram jar and it has a good price of $4 with free shipping. I’ve seen other people use this stuff with good results so I decided to give it a try. I’m not sure if there are any fakes to this particular brand, but the ones from banggood seem to be the genuine stuff.

The consistency is that of a paste so I don’t think it would be easy to put this inside a syringe and use it that way. This works better if you pick it up with a toothpick or some tweezers. This is not rosin based or so they advertise, and it’s supposed to be a neutral PH,with low corrosion to your pcb and components. You will probably see me use this in a future video, until then, there will be a link in the description so you can order one.
