Cyberdeck project
Road to design my own cyberdeck,
Raspberry pi3 , LCD 5 inch, LAN, USB, Aux
STM32 (Bluepill) with i2c bme280
Sample code stm32duino upload via stlink
#include <Wire.h>
#include <SPI.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
Adafruit_BME280 bme;
void setup()
{
Serial.begin(115200);
bme.begin(0x76); //i2c address must declare,or try i2c scanner first
}
void loop()
{
Serial.print("Temperat: ");
Serial.println(bme.readTemperature(),1);
Serial.print("Humidity: ");
Serial.println(bme.readHumidity(),1);
Serial.print("Pressure: ");
Serial.println((bme.readPressure()/100),1);

Rumus menghitung panjang antenna LoRa 923 Mhz untuk monopole antenna
Detailnya silahkan lihat video diatas
Dan untuk diindonesia karena menggunakan Freq 920-923 kira kira panjang antena yang digunakan adalah sekitar 7,79 – 7,81 cm

5$ DIY radiation shield
I made some fun project for weather monitoring for measuring temperature, humidity, pressure using BME 680, lora modul and my first sensor like this
And after a couple days i realize the sensor measuring temperature is too high maybe because sensor measuring inside the box, after googling and looking other solution and my idea is making radiation shield and i end up with DIY radiation shield using some cheap plastic plates.
I bought 2$ for 8 plastic plates but i only use 6 because my sensor is small, and i also buy some spacer for mounting the plates its 2$ for 20 spacer i’m using 1 inches spacer, and 1$ for other material like cable ties and also spray paint
And this is it my cheap radiation shield 🙂 and i’m happy for the result
Happy Coding
