CrossBridge Q
Things used in this project Project Overview: The Distraction-Free Digital Reading Hub Reading long-form essays and news online has become an obstacle course of animated ads, cookie banners, autoplay videos, and bright screen glare. While dedicated e-paper devices offer the ideal paper-like reading experience, getting web content onto them is notoriously frustrating—usually involving clunky browser extensions, manual USB cables, or third-party cloud services that harvest reading telemetry.
AtmosGuard C5: Dual-Band IAQ & Cloud Logger
Things used in this project Seeed Studio xiao esp32c5 × 1 × 1 Seeed Studio Grove - Formaldehyde Sensor (SFA30) - HCHO Sensor × 1 × 1 1. Introduction Indoor air quality (IAQ) is often overlooked, yet it directly impacts cognitive function and long-term health. High CO2 levels lead to drowsiness and poor concentration, while Formaldehyde (HCHO)—often emitted from furniture and building materials—is a known irritant.
Things used in this project × 3 × 3 × 1 In this project we will learn on making water level indicator using linkit one board. This project could help you save water more efficient. There will be 3 led indicating different water level.
Wio Tracker L1 Gateway
Things used in this project Seeed Studio wio tracker l1 × 1 × 1 × 1 × 1 × 1 The Idea Imagine combining the power of an off-grid LoRa mesh with the intelligence of cloud-connected telemetry. The Seeed Studio Wio Tracker L1 Series Meshtastic Development Kit provides the perfect foundation: an ultra-low-power nRF52840 microcontroller, integrated LoRa radio, and high-precision Quectel L76K GPS. This development kit is already a reliable Meshtastic node for communication in remote areas.
Stand Up Reminder!
Things used in this project × 1 Introduction We live in a world where many of us spend hours every day sitting at a desk — coding, working, or watching screens. But research shows that sitting too long without moving increases the risk of obesity, heart disease, and even early death. Doctors call it “sitting disease”, and it’s been linked to poor blood circulation, back pain, and reduced focus. The best cure? Stand up and move regularly.
Digital Lab Sensor Display
Things used in this project × 1 × 1 × 1 × 1 × 1 Modern digital labs require not just computing power, but also real-time awareness of the environment. In this project, you'll build a wireless temperature and humidity display system using two ESP32 boards, a SHT40 sensor, and a MAX7219 LED matrix. But here’s the twist — it doesn’t need Wi-Fi or an internet connection.
On Track with Thingy:91 X using nRF Connect SDK
Things used in this project Welcome to the maker train workshop at FAB25. Before we begin, if you just unbox your Thingy:91 X for the first time. You might want to try the preloaded firmware that already come with the device. Chris Wilson already made an excellent guide on how you could use the preloaded firmware on this page. I recommend you to try this before we are starting with our workshop to get the better understanding of the Device that we are going to use for this workshop.
