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...

Schematics / AssemblySolder the elements on the printed circuit board according to the circuit diagram, instructions and markings placed on the printed circuit board.Connect the WeMos MiniID1 ESP-32, 16 pin male header using soldering or connectors.Insert...
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.
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*/...
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...
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...

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...
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...
