Gerber to PCB in 30 Minutes at Your Desk: PewCB One Pairs a Laser With Vias-Ready Double-Sided Blanks A new desktop machine called PewCB One wants to bring PCB fabrication into the same room as the engineer designing it. Instead of exporting a design and waiting on a fab house, PewCB One promises to turn Gerber files into a populated double-sided circuit board without leaving your desk.
The system is built around a 20 W, 1064 nm pulsed laser that… |

How to Send Data from ESP32 to Firebase Realtime Database In this tutorial, we’re going to learn how to send data from an ESP32 to Firebase Realtime Database. We are using ESP32 Firebase Google as our cloud platform. A lot of cloud-based IoT projects on YouTube / GitHub / similar platforms using ESP32, ESP8266, UNO R4, or similar microcontrollers use Firebase as the cloud platform. And this guide covers the complete ESP32… |

How to Build a Smart Parcel Tracking System Using IoT Imagine you've just sent a parcel through a courier service. As soon as it leaves your hands, you start wondering what is happening to it. Is it being handled carefully? Has it been dropped or damaged? Is it still on the right route? Will it reach the destination safely and on time? The truth is, once we send a parcel, we have very little idea about what happens… |

A Homemade Approach to Long-Range Night Vision Most infrared night-vision systems are limited to relatively short distances mainly because standard IR LEDs spread light too widely to be effective over long ranges. Curious about the practical limits of infrared imaging, the independent engineering channel Project 326 developed a custom-built system aimed at long-range nighttime observation. The system combined a modified low cost… |

Clock Uses Water Bottles as Pixels With Membrane Pumps and Servos Maker Strange Inventions has built a water-based digital clock in which 60 small bottles act as individual pixels, collectively forming numerals to display the time. The bottles, sourced at 10 cents each, brought the total project cost to approximately $580. Each bottle is filled or emptied with dyed water to switch its pixel state on or off, with the display controlled by a microcontroller… |

bUniProbe, a Multi-Protocol Hardware Debugger with a Web Interface There's no shortage of tools to test and debug hardware, but not many feature interfaces for SPI, I²C, UART, CAN, GPIO, ADC, and DAC in one device. bUniProbe is one of the few, and its hardware side is just half the story. It hosts its own web interface over Wi-Fi, so anyone on the network can open a browser, connect, and start working. This means multiple users can work together without the… |

Build a Simple Optocoupler Tester Circuit for Fault Detection Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials… |

LiteWing Maneuver Control System – Autonomous Drone Navigation Using Optical Flow Sensor The Maneuver Control system is the final logical extension of the LiteWing Flight Positioning Module. While the Position Hold system focuses on maintaining a fixed point in space, maneuver control enables the drone to intentionally move to new positions while remaining fully autonomous and stabilized. The key distinction is that maneuver control does not introduce… |
