DIY: Marauder with Screen and GPS For Flipper Zero

Many of you would have seen the humongous ESP32 add-on module with touch screen and GPS for Flipper Zero shared in discussion groups, forums, etc. Well, this tutorial will provide you with all the information you need to build one yourself.

This build consists of mainly 4 parts. The TFT LCD 2.8" 240x320 SPI ILI9341 Touch Display cost me around US$5.50, the ESP32-WROOM-32U module cost around US$3, the NEO-6M GPS module cost around US$2.20 and an 8dbi 2.4GHz Wifi Antenna which cost around US$2. All of these parts can be easily found in online marketplaces like Aliexpress, Amazon, etc. Here is how you need to wire them up together. How you wish to lay this out or mount on a prototyping board is entirely up to you. As long as the connections are correct, you are good to go. The GPS module is optional, and mainly, it's used for the war driving functionality.

Next, you need to download all the firmware needed from here. Please download the Bootloader, Partitions, Boot App and Firmware files for v4 (Yes, v4 files, not any others) and save it on your computer.

Now, press and hold the BOOT button on your ESP32-WROOM-32U module and connect it to your computer using a data-capable USB cable (some USB cables can only charge), then let go the BOOT button. Open Google Chrome or Microsoft Edge browser and go to ESPWebTool. Click the CONNECT button, then select the ESP32 usb serial connection. It should look something like below but can vary a little between different computers and operating systems.

Select the firmware files for each slot exactly like below (take note of the 0x1000, 0x8000, etc. and their corresponding .bin files), then hit the PROGRAM button.

When completed successfully, you can unplug the USB cable from the ESP32 module and now you can connect your Marauder module to your Flipper Zero. Please ensure that your Flipper Zero is turned off before you connect it, and also turn off your Flipper Zero before disconnecting it. The 3.3V pin is also used by your Flipper Zero's SD card reader and connecting/disconnecting external modules that use this pin while the Flipper Zero is on can potentially corrupt the SD card. So, if everything went according to plan, your Marauder module should boot up and everything should look like below.

NOTE: If your Marauder boots up, but when you try to touch the screen and get no response, try tapping around the bottom part of your screen and see if the touch panel seems to be in inverted position from the actual display. Should this happen to you, just flash your ESP32 module again following the steps above, but use the v6 firmware. This should resolve the issue.

In this build, I just prototyped this on breadboard, but you can of course make it permanent by soldering it on to a prototype board and 3D print a case for it. This setup is essentially just using the Flipper Zero as a battery pack, instead of using the Flipper Zero to control Marauder. The large screen does make some things easier to do, compared to the small screen of the Flipper Zero, and there may be some functionality (not much) that is not currently in the Flipper Zero Marauder companion app. Here is a video showing the different menus in Marauder.

Personally, I don't think I will actually want to bring something so big around with me, along with my Flipper Zero. I think what makes Flipper Zero special is just how compact it is and all the different functionality cramped into it. This would probably be better off as a standalone unit by just hooking up a battery, but that's just me. Well, that's it for this tutorial. I hope you found this helpful. If you haven’t already done so, check out my Makers & Hackers Exchange Facebook group to learn more from other Flipper Zero users.

Here's a good intro to Marauder if you are unfamiliar.

Ceramic Auto Tint Key Features

Ceramic Auto Tint Key Features

Ceramic window tint has a reflective external look and works to keep your car from absorbing excess heat. It also provides privacy by making it harder for people outside your vehicle to see inside. This is achieved by a hard section infused with nanoparticles that aid in the reflection of UV and Infrared radiation. The next layer is a transparent polyester sheet that adds strength and reduces scratching.

It’s Shatterproof

Ceramic tint for cars is shatterproof, protecting your vehicle’s windows from glass fragments that can be caused by road debris. It is also highly effective in resisting heat and solar glare while maintaining optical clarity. Ceramic tint also reduces the risk of theft by making it difficult for criminals to see the contents inside your car. A new car theft is reported every 36 seconds in the US – ceramic tint can help protect your valuables by deterring criminals from breaking into your vehicle. All ceramic tints rely on nano-ceramic particles to block the sun’s harmful UV rays and infrared light, but some newer innovations  go even further with concentrated, enhanced nano-ceramic technology to provide unparalleled performance. Unlike cheap tint that fades and needs replacing over time, ceramic auto tint is designed for the long term and will continue to look great year after year. It also provides superior privacy for passengers and the interior of your vehicle.

It’s Energy Efficient

The best automotive tints block 98% of the sun’s harmful ultraviolet (UV) and infrared (IR) rays. They also reject a lot of heat, keeping your car’s interior cooler and decreasing the need for air conditioning. This can help you save money and reduce your carbon footprint! Regular tint fades and bubbles, but premium ceramic films are durable. They don’t change color or scratch and are easy to maintain. Unlike dye-based films, they don’t interfere with built-in antennas or sensitive on-board electronics. They also have a lower Solar Heat Gain Coefficient and a higher Total Solar Energy Rejected (TSER) percentage, making them more energy efficient than traditional tints. A new car theft is reported every 36 seconds, and ceramic tints make your vehicle less attractive to potential thieves. They also provide increased privacy without darkening the windows too much. Additionally, ceramic tints don’t interfere with cellphone or radio signals, which is a major benefit for busy people on the go.

It’s Durable

Unlike dyed tints, ceramic window film for cars won’t fade or lose its color. Its high quality construction enables it to withstand extreme temperatures, while also keeping the vehicle cool and comfortable.

Detecting Storms Thanks to GPS - Technology Org

New Post has been published on https://thedigitalinsider.com/detecting-storms-thanks-to-gps-technology-org/

Detecting Storms Thanks to GPS - Technology Org

Researchers at ETH Zurich have succeeded in detecting heavy precipitation events directly with GPS data. The results of their study could significantly improve meteorological monitoring and forecasting.

Electric discharge during a thunderstorm. Image credit: Pxhere, CC0 Public Domain

An exceptionally severe storm swept over Zurich on 13 July 2021 shortly before 2 a.m.: howling squalls, constant lightning and torrential rain woke people up with a start. Benedikt Soja, Professor of Space Geodesy, also got little sleep that night. “It was one of the most severe storms I’ve ever witnessed. I woke up in the middle of the night and could see the storm raging through the window,” he remembers.

The scale of the storm was evident the next morning – fallen trees on streets and in parks, damaged rooftops and overhead tram lines pulled down in various parts of Zurich. The ground in the vicinity of the Hönggerberg campus was also strewn with branches and even entire trees. “The storm must have passed right over ETH,” says Soja.

GPS data outages

A GPS station on the roof of the Institute of Geodesy and Photogrammetry on the Hönggerberg campus records the signals of various satellite systems around the clock. When examining the data of the night of the storm in more detail, Soja and his colleagues at the Institute couldn’t believe their eyes. “There were outages in the GPS data processing. We couldn’t understand at first what had caused them,” says Matthias Aichinger-​Rosenberger, a former postdoc in Soja’s group and now a lecturer at ETH Zurich. When other stations also reported outages in the measurement of data from GPS and other satellite navigation systems for that night, the researchers started to analyse the raw data of the antenna on the Hönggerberg campus.

They were able to show in the study, which was published in the specialist journal external pageGeophysical Research Letterscall_made, that extreme weather events influence the quality of GPS signals and that these signals are therefore also suitable for detecting storms. It could one day even be possible to use them for the early detection and forecasting of thunderstorms.

The signal-​to-noise ratio dropped

The scientists drew their conclusions from the analysis of the data of the storm of 13 July and of another storm in the summer of 2021. It became evident that the extreme weather events had an impact on the signal-​to-noise ratio, which indicates how strong the satellite signals are that reach us on the earth. The higher the ratio, the better the quality of the signal.

“The signal strength that we measure with our antenna on the roof normally only changes minimally,” says Aichinger-​Rosenberger. However, this was not the case on the two storm days: “The signal-​to-noise ratio in the GPS data dropped considerably at the time of the storm. We saw that once the storm had moved on it was back in its normal range.”

In order to determine the precise time of the storm’s arrival and to check whether this matched the time when the signal-​to-noise ratio dropped, the researchers compared their data with radar data of the University of Berne. “This confirmed our suspicion that there was a direct connection,” said Aichinger-​Rosenberger.

Was it heavy rain or hail?

The researchers are certain that heavy precipitation is responsible for the sudden drop in the signal-to-noise ratio. What is not clear is which type of precipitation—rain or hail—has a greater impact and why. The scientists wish to find out in the future.

As simple as the study’s result may sound, it is a breakthrough for space geodesy research. “It has never been proven yet that severe thunderstorms and other weather events with heavy precipitation significantly influence the signal-to-noise ratio,” says Aichinger Rosenberger. Until now, it has been assumed that GPS is a weather-independent system. Now, it appears that GPS data are sensitive enough to capture such atmospheric disturbances.

Forecasting precipitation more reliably

These findings could open up new prospects for the use of satellite navigation data in meteorology. “We now wish to collect more measurements in order to improve the forecasting of precipitation in weather models,” says Soja. Reliable precipitation forecasting still remains a major challenge. “Many other meteorological parameters such as the temperature can now be predetermined quite well with numerical weather models. Unfortunately, however, such models are often not good enough in the case of precipitation.”

In order one day to make use of the ETH researchers’ findings for forecasting, they need to be brought into relation to a weather model. “In order to transfer our observations to specific parameters such as the water and ice content in the air or the storm’s direction of movement, we need to collect and analyse further data. These findings could then be incorporated into a computer-​based weather model in order to improve the forecasting of precipitation,” says Aichinger-​Rosenberger.

More receivers needed for early detection

Storms still need to pass directly over the measuring station for GPS signals in order to be detected. Because the network of measuring stations is not sufficiently close-​knit, the method is not yet suitable for the early detection of storms. “If, for example, we had thirty to forty stationary receivers around Zurich, we would be able to capture extreme weather events across the city accurately and also very cost-​effectively,” explains Soja. “A dense network of stations could also be used to determine where storms are moving to and how fast.”

Such an early detection system could in future be used, for instance, to ensure safe air traffic, says Soja. “A dense network of GPS stations around the airport would enable a storm to be localised in real time and warnings to be issued to this effect.”

As well as refining the method, the scientists are also planning to expand their research work across Switzerland and at the European level, to enlarge their network accordingly. Although the severe storm in July 2021 caused a lot of local damage, it also enabled knowledge to be gained that could one day be applied globally.

Improved GPS Attachment to Wifi Dev Board

I was playing around with the GPS module and the Wifi Dev Board, and I am still trying to figure out how I want all these modules to work/fit together, as I don't really need to have the GPS around all the time. Now, I am thinking maybe I will make the GPS module detachable from the Wifi Dev board.

I just soldered some female headers to the prototype board and wired them together. This is just a quick test rig, I will redesign a proper one with the GPS board permanently soldered on to make it more compact.

Now the GPS module can be easily attached or removed from the back of the Wifi dev board as needed. Once I am done modding the external antenna and SD Card for the Wifi Dev board, I will design proper 3D printed cases to make everything fit together.

In a short wardriving test, I logged a bunch of APs. I used GPS Visualizer to plot all the access points on a map, as you can see below.

Note that in order to get GPS Visualizer to work with Marauder's wardriving log file, you need to edit it to remove all the lines at the beginning and end of the file that are not listing access points, and add the following line (single line) to the very top of the file:

mac,name,desc,date,channel,rssi,latitude,longitude,elevation,accuracy,type

This is so that GPS Visualizer knows which column contains what data.
