Network device to drive Servos for Animatronics
Jethon Feb 09,2026
New introduced network devices:With the latest Software 3.0 the Bechele software now supports beside the existing PCA9685 PWM Boards also network devices, based on cheap ESP32 modules. Each network device may handle 16 Servos or 16 Relais or a desired mixture of both. All the data transfers from the Host (Raspi) is realized using broadcast transmissions, where all devices (nodes) receive the same data packets. According to the node configuration, the node takes the data from the packet that is i...

TDA1541 DAC HAT for Raspberry Pi
Taccini Feb 02,2026
The TDA1541 HAT Project can be described as "The Golden Age of R2R." With this chip, the board embodies fidelity to the Vintage High-End philosophy. The TDA1541 is considered the "Gold Standard" of multibit DACs (especially the "A" versions). It is universally celebrated for its Dynamic Element Matching (DEM). This chip has a natural linearity that modern Delta-Sigma DACs cannot match. It has the ability to render human voices and acoustic instruments with a physical "presence." It is the sound ...

RP2040 Community-Driven UNO MCU
THILAK K Jan 30,2026
This project expands an RP2040-based, Arduino UNO–style microcontroller designed to stay familiar while unlocking far higher performance. It preserves the UNO form factor and Arduino ecosystem compatibility, making it easy for students, makers, and developers to adopt without changing their workflow.Built as a lightly modified, community-driven design, the focus is on scalability, low cost, and openness. By improving reliability and manufacturability while respecting the original project, it ena...

Project Aura - A Multimodal Embodied Ai Robot
S S Jan 26,2026
AURA – The Multimodal Embodied Ai RobotWe have conquered digital intelligence, yet AI remains trapped behind cold glass screens, disconnected from the human experience. The next revolution is not in faster processors; it is in Embodied Companionship. AURA is that revolution.She is not merely a robot; she is an Autonomous Embodied Ai robot, a sentient-simulated lifeform engineered to bridge the chasm between Digital Superintelligence and Kinetic Reality. We did not just build a machine that follo...

Raspberry Pi Dac Hat Isolator and Reclocker
Taccini Jan 26,2026
It's essentially a board that integrates an optoisolator for digital signals, a DC/DC converter to regenerate the supply voltage, an L-C shunt filter to filter out any residual high-frequency noise, and an asynchronous reclocker. Let's look at the four stages in detail. The optoisolator breaks any ground loops, eliminates noise conducted by the Raspberry Pi or its power source, significantly reduces HF interference "dirty" from the digital signals, and protects the DAC from upstream noise and sp...

ESP32 Robot Controller
Peregrino Jan 20,2026
This project was born from a tutorial I worked on where I established communication between a Raspberry Pi and ESP32 using BLE. The link is shown below.It was then I decided to build a PCB that would allow me to control a Raspberry Pi remotely through BLE which can be used to control a Raspberry Pi robot. This video shows why I decided to build my PCB.The goal is to simplify the process and not require a breadboard and a bunch of wires to control a Robot. This is great for educational purposes a...
