Intro This simple LED matrix display is easy to build and is able to display a shared screen just using the browser. No special software or operating system is needed on the sharing PC. This way it’s easy to display animations, images, feeds or symbols on this matrix. The 3D printable case is made from …
This tutorial shows the build of the mini lamp from the video in detail Needed components (affiliate links): 16×16 Flexible RGB LED Matrix ($13)ESP8266 D1 MiniPower Supply 5.5mm Barrel Jack 3D PrintThe blender and stl file can be found on thingiverse . The blender file is only needed if you like to modify it. The …
This LED lamp is a quick project that can be done within a day. Only a few cheap components are needed to create a nice looking ambient lamp. No programming is needed, only the WLED firmware is uploaded to a micro controller via a simple tool. A 3D-Printed version simplifies the build process a lot …
Hardware This project is based around the ESP32-Cam. It’s widely spread and costs $6 from Aliexpress. It’s programmed using a USB to Serial converter. Since ESP32 boards need to be reset with GPIO0 to ground to be able to upload a sketch I made a simple programmer that does the resetting and programming all an …
The journey continues. A few months ago I built an LED Wall and the video on the went viral (for my level at least). Still there is potential for more so I spent even more money on LEDs Aluminium sheets. Since drilling 300 holes in the first wall was already painful enough I thought why …
I played around with the I2S features of the ESP32 and found a way to generate a VGA signal. The Memory limits the resolution a bit but it’s still awesome.
Intro The CRT BOY is a simple project that tries to build a Game Boy clone using a small CRT screen. The end result will look like a even more retro Game Boy from the 80ies. The micro controller based on the ESP32 is not so retro is strong enough to emulate consoles from the …
A simple USB MIDI device sending notes to a common PWM module Compatible with all devices suppoerted by the MIDIUSB library under construction… come back later :-* Code & models The code can be found here https://github.com/bitluni/MalletsBot Need to install the following libraries in the Arduino IDE to run: https://github.com/arduino-libraries/MIDIUSB https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library Models are exported as …
This mini project shows an attempt to built a cheap areal 3D scanner. The two attempts use an ultrasonic transducer and a time-of-flight sensor. The project ist Arduino based with the ESP8266 board extension. While it’s still work in progress this page will grow with additional information. Parts I put together some affiliate links. These …
