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...
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...
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...
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*/...
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,...
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...
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.
Begin with 200ml filtered water from the fridge tap, carried in an empty coffee pot. Using 4-6 ratio to calculate. 10x20 = 200ml H2O 4 grams sodium hydroxide x20 = 80 grams NaOH 6 grams silica x20 = 120 grams Unfortunately we only have 92.8 grams of...
I wanted to use a BMP280 I had in my parts bin for altitude measurements. I have used it in the past for a simple weather station and it works great! Turns out, it is even the go to sensor for Stratux, so I went ahead and plugged it in, activated it...
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...
Plug in the freshly minted EDID Inserter and a repeated invocation of the following should yield only 256 FFs typical of an EEPROM fresh from the factory:sudo i2cdump 3 0x50Dire admonitions are issued even when merely trying to read:No size specified...
