WLED is a powerful open-source firmware designed for controlling addressable LED strips, including NeoPixel LEDs like WS2811, WS2812B, TM1809, and more. It supports ESP32 and ESP8266 devices, making it a go-to solution for DIY lighting projects. WLED runs a local HTTP server with a sleek, modern UI, allowing you to control your LEDs easily from any device on the same network. It also integrates seamlessly with Home Assistant, enabling smart home automation, voice control, and advanced lighting effects.
In this tutorial, you will learn the exact steps to install WLED directly from a web browser onto an ESP32 board—no additional software required. The demonstration uses Google Chrome and the ANAVI Miracle Emitter, featuring the XIAO ESP32C3 RISC-V microcontroller. To install WLED from a web browser, visit: https://install.wled.me/.
ANAVI Miracle Emitter is an open-source hardware IoT development board for controlling NeoPixel LEDs. Furthermore, it supports various I2C sensors and a mini OLED display. I designed the printed circuit board (PCB) using the popular open-source software KiCad. It will soon be available through a crowdfunding campaign on Crowd Supply.

In the coming months we stock ANAVI Dev Mic through other trusted distributors and online stores. As usual, stay tuned for further technical updates and new exciting open source projects!
Our crowdfunding campaign at Crowd Supply for ANAVI Dev Mic successfully wrapped up on September 26th, and we couldn’t be more grateful! Thank you! Over 30 backers from eight countries supported this open-source hardware project for a computer microphone powered by the Raspberry Pi RP2040 microcontroller.
ANAVI Dev Mic is a compact, affordable, exceptionally adaptable open-source microphone. The printed circuit board has been designed with KiCad and feetures Seeed Studio XIAO module with the Raspberry Pi RP2040 microcontroller and an omnidirectional digital microphone that work together to ensure high-quality sound capture and processing.
The production of the printed circuit boards and component assembly is now complete, and we’ve also finished the laser-cut acrylic enclosures. Packaging materials, including cardboard boxes and stickers, are ready to go. In the coming weeks, we’ll complete packaging and transfer everything to the warehouse. From there, Crowd Supply’s fulfillment service will ship the ANAVI Dev Mic kits to all our backers.
Thank you again for your tremendous support, feedback, and contributions to our GitHub repositories. More updates are coming soon—stay tuned!
The ANAVI Dev Mic is a small, open-source microphone kit designed for hobbyists and developers. It’s easy to assemble on your own, even with minimal tools. While you can complete the assembly using just your hands, a screwdriver will make the process quicker.
Components
When you open the ANAVI Dev Mic kit, you’ll find the following parts:
Black PCB with gold plating and white markings
Acrylic top cover
Acrylic bottom cover
Four 10 mm screws (M2.5)
Eight M2.5 nuts
NOTE: The kit does not include a USB-C cable. You can use one you already have or buy one separately.
Step 1: Remove Protective Layer
The acrylic covers are laser-cut and come with a protective film on both sides. Carefully peel off this film to reveal the clear acrylic.
Step 2: Attach the Top Cover
Take the PCB and the top acrylic cover, which has a circular cutout for the microphone. Align the cover with the corresponding circle on the PCB. Insert a screw into each of the four mounting holes and secure them with the nuts provided.
Step 3: Install the Bottom Cover
Next, place the bottom acrylic cover over the side of the PCB where the XIAO RP2040 module is located. Secure the cover by tightening it with the remaining four nuts.
Step 4: Connect and Use
With these simple steps completed, your microphone is ready to go. Just plug ANAVI Dev Mic into your computer using a USB-C cable, and you’re good to go!
Do you remember the ANAVI Macro Pad 2, our tiny mechanical keyboard with just two keys? Built around the Microchip ATtiny85 microcontroller, it comes with QMK version 0.13.19 and is often used as a cool copy-paste keypad. However, its open-source firmware can be reprogrammed for various uses. Recently, Henrik shared a Crowd Supply “field report” about his impressive setup, using the ANAVI Macro Pad 2 to control audio streams with his favorite songs. Although the ANAVI Macro Pad 2 was successfully funded on Crowd Supply three years ago, in June 2021, we continue to update the documentation and share news with our backers. It’s fantastic to keep improving the product based on community feedback.
Henrik created a custom QMK keymap for the ANAVI Macro Pad 2 based on his needs: the left button is for “play/pause,” and the right button is for “next song.” He even configured the LEDs to light up when the buttons control media playback. Why hire a DJ when you can be the DJ with your homemade setup using the ANAVI Macro Pad 2?
After modifying the firmware, Henrik made a hardware customization. For fun, he changed the keycap on the right button to one featuring a sleeping unicorn. This new keycap, being heavier than the default translucent one, adds weight to the otherwise lightweight ANAVI Macro Pad 2. The keyboard comes with Gateron red mechanical switches, which are Cherry MX compatible, allowing for easy keycap changes. Henrik also shared his plans for future modifications, including a second custom keycap.
The Open Source Hardware Association (OSHWA) officially certified our new gadget ANAVI Handle in April. ANAVI Handle is a small USB-C adapter with XIAO RP2040 that allows you to use Wii Nunchuk-compatible controllers as USB HID peripherals on your personal computer. You can configure ANAVI Handle to adapt the controller as a joystick, keyboard or a mouse.
OSHWA, a prominent U.S.-based non-profit, manages the Certified Projects Directory and annually hosts the prestigious Open Hardware Summit. Their certification program ensures that a project’s interpretation of “open source hardware” aligns with the community’s standards, promoting transparency and accessibility.
Each certified hardware version is identified by a unique identification number (UID) that includes a country code and a numerical sequence. On April 19th, ANAVI Handle version 1.0 was certified with the UID BG000134. This UID, displayed through the OSHW Certification Mark, simplifies navigation and information access for interested parties. The “BG” prefix indicates that the ANAVI Handle is from Plovdiv, Bulgaria, a city renowned as Bulgaria’s second-largest and Europe’s oldest continuously inhabited city, with over 6000 years of history.
Our projects, including the ANAVI Handle, are distinguished by our unwavering commitment to complete openness. Every aspect of our design and functionality is made accessible to all, reflecting the true spirit of the open-source community. From the KiCad-designed printed circuit board to the highly-configurable firmware powered by CircuitPython, we exclusively use free and open-source software.
The ANAVI Handle is an open-source hardware USB adapter for the Nintendo Wiimote connector. Its open-source firmware transforms the Nunchuk controller into a USB mouse, keyboard, or joystick. If you missed out on the crowdfunding phase, don’t worry—you can still snag a kit from Crowd Supply.
After months of diligent research and development, we’re thrilled to unveil the launch of the crowdfunding campaign for the ANAVI Handle at Crowd Supply. This open source USB adapter bridges the popular wired Wii Nunchuk controller to personal computers, integrating open-source hardware with free and open-source software.
Designed using KiCad, the printed circuit board is gold-plated. The main component is Seeed Studio XIAO module with Raspberry Pi RP2040 microcontroler. The firmware of ANAVI Handle, driven by CircuitPython, guarantees effortless functionality, featuring versatile modes for joystick, mouse, or keyboard use.
The crowdfunding target for the ANAVI Handle is intentionally humble, marked at a mere $1. Your backing will help production in Plovdiv, Bulgaria, EU, tapping into our trusted supply network. Join us by placing an order and breathing life into this wholly open-source endeavor!
As we step into 2024, we extend our warmest wishes to all makers and engineers passionately involved in open-source software and hardware ecosystem. May the coming year be filled with groundbreaking projects, collaborative efforts, and success in all your endeavors!
