Meshstatic

Introduction Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source! Features​ Long range (254km record by kboxlabs) No phone required for mesh communication Decentralized communication – no dedicated… Continue reading Meshstatic

LoRaWAN Demo

There are two methods for Raspberry Pico and Pico-LoRa-SX1262 to connect to the network via LoRaWAN: OTAA (Over-The-Air-Activation) and ABP (Activation By Personalization). Here we use OTAA, as shown below. Step 1: Please send the “Join-Request” message to the network to be added, and note that the adding process is always initiated by the end… Continue reading LoRaWAN Demo

Introduction to LoRaWAN

LoRaWAN is a low-power wide area network open protocol based on LoRa radio modulation technology. Aims to wirelessly connect battery-powered “things” to the Internet in a regional, national, or global network and targets key Internet of Things (IoT) requirements such as bi-directional communications, end-to-end security, mobility, and localized services. Node wireless connection to the Internet… Continue reading Introduction to LoRaWAN

Introduction LoRA

LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech’s LoRa is a long range, low power wireless platform that has become the de facto wireless platform of Internet of Things (IoT). LoRa devices and networks such as the LoRaWAN® enable smart IoT applications that solve… Continue reading Introduction LoRA

3D printer bed -Tapes

Kapton Tapes Kapton tape, also known as polyimide tape, serves as an additional layer atop an existing print bed rather than a standalone build plate. This adhesive tape comes in spools with one adhesive side for attachment and one side composed of polyimide. The polyimide side offers exceptional adhesive properties, providing strong adhesion for materials… Continue reading 3D printer bed -Tapes

3D printer bed -Spring steel PEI

Spring steel smooth PEI Spring steel smooth PEI build plates have gained popularity, particularly seen in stock versions of printers like the Prusa i3 MK3S+. These plates feature a base of spring steel, known for its flexibility and ferromagnetic properties, making bed removal and reattachment effortless. The flexible nature of the steel facilitates easy part… Continue reading 3D printer bed -Spring steel PEI

3D printer bed – Glass

Introduction The print bed, also referred to as the build plate, stands out as a critical component in any FDM 3D printer setup. Without a quality build plate, or even without one altogether, your printer’s performance could suffer, potentially leading to print failures. Essentially, the main role of a print bed is to furnish a… Continue reading 3D printer bed – Glass

Gas Sensor

Gas sensors are devices that detect the presence of various gases in the environment and convert this information into an electrical signal. These sensors are used in a wide range of applications, including industrial safety, environmental monitoring, and indoor air quality control. Here are some key points about gas sensors: Working Principle: Gas Detection Mechanisms:… Continue reading Gas Sensor

Raindrop Sensor

A raindrop sensor, also known as a rain sensor or rain detector, is a device used to detect rainfall or the presence of water droplets. It is commonly used in weather monitoring systems, automatic irrigation systems, and rainwater harvesting systems. Here’s an overview of how raindrop sensors work and their applications: Working Principle: Raindrop sensors… Continue reading Raindrop Sensor
