In the arduino code set your WiFi credentials char wifissid[] = "ENTER YOUR WiFi SSID HERE"; char wifipass[] = "ENTER YOUR WiFi PASSWORD HERE"; Normally, the signal strength is displayed in dBm. But for a non techie person, the signal strength in terms...
Make you the PCB and get the components and any standard 60mm 4-wire fan will probably do the job. I used a JMC "6015-12HB APW" that I had lying around. The exact the same fan is readily available on eBay.I used eagle to design my PCB, and the files...
Support for the ESP32-S3 Open Book is very early at this time; there is no prebuilt firmware image, so you'll need to have both Visual Studio Code and PlatformIO installed. Download the Libros firmware from GitHub, open...
Now that i know how to access and decode the data lets try the Raspi GATTTOOL default BLE handler:Native to Debian and a lso to a bunch of linux distros or so i've heard of . First i reset the bluetooth of the raspi, just in case: sudo service bluetooth...
Flash the Arduino with the following sketch. This is also included as a file attached to the project. int last_level = 0; bool last_state = false; bool stable = false; int count = 0; const int cutoffs[198] = {/* 1*/ 833, 831, /* 2*/ 825, 823, /* 3*/...
This project would not be anywhere near as complete without some awesome online resources and some awesome people. I would like to thank the devs at Adafruit for making some incredibly useful resources. I referred to the Metro Mini and VL53L0X product...
First check the you have necessary materials to make the project. You need some 3D printed parts, so a printer is necessary or at least the posibility of print. We print with protopasta carbon fiber filament but you can print in PLA, thats if you want...
I've had comments regarding the validity of using Geiger–Müller Tubes for a cosmic ray (muon) detector. Pointing out that Photomultipliers and scintillation panels are best, and yes the are far more effective. However, they are also expensive,...
The ESP-32 board pins operate in 3.3v levels while the Gravity pH and EC sensors operate in 5V. I inserted a simple voltage divider to shift 5v to 3.3v levels on the signal pins.
You will need a Lipo battery with 100mAh capacity, you can get a higher capacity one but take into account that more capacity means a bigger battery so it won't fit into the board, the battery must have a protection circuit included. The battery must...
Add ESP32 board Open the Arduino IDE.Go to File> Preferences.In the “Additional Boards Manager” URLs field, add the following URL: ‘https://dl.espressif.com/dl/package_esp32_index.json’.Click OK.
To build a tower you will need to print the 3D parts shown on the left of the image. The "Sensors float" part is optional, print it if you want to use the pH and EC sensors. You will need 12 times the part: "Basket". You can download the files...
