I have been contacted by a number of people in search and rescue (SAR) who are interested in the other Ripple LoRa mesh projects I have been working on, and it got me to thinking about making a dedicated device for the field personnel.This device doesn’t require a companion Android handset, as it has…
In this project, you’ll build a sensor monitoring system using a TTGO LoRa32 SX1276 OLED board that sends temperature, humidity and pressure readings via LoRa radio to an ESP32 LoRa receiver. The receiver displays the latest sensor readings on a web server. More info
https://youtu.be/3LkKYtQqzKo Sometimes clocks lose their time and you have to set up it again. If you don’t want to get bored any more make your own digital clock! It uses a wemos D1 board which gets data from an ntp(network time protocol) server and shows time on an OLED lcd. Don’t miss it! …

Youtuber Electronic Grenade, a DIY enthusiast, has created something truly impressive in the form of a mouse that doubles up as a full-fledged computer. Aptly called ‘The Computer Mouse’, the device has a small colour display, a slide-out keyboard, and of course, a fully-functional mouse which also forms the main body. The mouse is a…
Moscow-based artist Dmitry Morozov has created a very innovative device called the Hot Ninja that is capable of messaging other devices using wireless SSIDs. “Multifunctional network device for autonomous activity in the city environment. Its main function is communication and propaganda through the Wi-Fi wireless standard. This is the hacktivism diy response to attempts by…
A day ahead of Oculus Connect 4, Oculus has released documents for its second generation development kit. DK2 improved upon its predecessor (DK1) with a 1080p OLED display and positional tracking via an external camera. It in turn was succeeded by the Crescent Bay prototype which laid the foundation for the first consumer version of the Rift,…
Instructables author Daniel Quintana loves mountain biking, but after having to interrupt a ride to continuously check the time, he did what any normal maker would do in this situation: he created his own Google Glass-like headset from scratch. His creation, called Uware, takes the form of a 3D-printed enclosure with a tiny 0.49″ OLED screen…
If you’re thinking of getting into DIY synths, the mini-TS could be your ticket in. Built by Janostman, the mini-TS pushes the limits of completely stripped back sound synthesis. The adorable synth shares the same basic sound-generation firmware with his previous TinyTS, but features a lot more keys (2 octaves), an OLED, and MIDI in/out, while…
One of the first applications of the original Raspberry Pi was building a homebrew smartphone, but the launch of the smaller Raspberry Pi Zero, followed by the Raspberry Pi Zero W, has allowed makers to build even smaller versions. Resembling nothing more than one of the old Nokia 3410s turned inside-out, the ZeroPhone is designed…
Program it to invent smart objects. For IoT, robots, wearables, your bright ideas. With sensors, strong MCU, bluetooth, oled & more. This compact and powerful solution has a lot of interesting features: free available 3D printing case files ARM cortex M4, based on the STM32 Nucleo board OLED displays available programmable in C and MicroPython…
