Loona Deskmate – An iPhone-powered AI desktop companion that doubles as a 165W GaN charging station (Crowdfunding)

Loona Deskmate is a screen-aware AI desktop companion for iPhone designed to act as a hands-free co-worker that understands your workflow, responds conversationally, and executes tasks directly across your apps. Instead of packing an expensive internal SoC and display into the robot, the Deskmate relies on a docked iPhone to act as its “brain” and face, while the base serves as a 165W GaN desktop charging station. It features real-time voice interaction (~0.5s response time), screen awareness, and a 3-DOF motorized head for lifelike motion and responsive behavior. The system relies on a smartphone (iPhone 12+) for computing and uses its camera and sensors for visual and contextual input. The base integrates a 165W GaN power hub with multiple ports (3× USB-C + 1× USB-A), allowing it to function as a desk charging station. Overall, the hardware combines a robotic form factor with a practical docking and power solution designed […]

WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)

Hack The Board’s WiQwiic-32 is a small USB-C IoT development board based on an ESP32-S3-WROOM-1 Wi-Fi and Bluetooth module, and equipped with a 1.14-inch LCD and eight Qwiic ports for easy prototyping with compatible modules. It also features a microphone and a buzzer for audio interaction, four buttons, two RGB LEDs, and a power LED. There aren’t any through-holes for GPIO pins, so expansion is only possible through the Qwiic connectors, although you can always add a Qwiic to header converter module if you ever need breadboard-compatible GPIO headers. WiQwiic-32 specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM Storage – TBD Wireless – WiFi 4 and Bluetooth LE 5 Antenna – PCB antenna Display – 1.14-inch TFT display Audio On-board buzzer Built-in microphone for voice and sound detection USB […]

DeskUp Pro smart standing desk controller integrates with Home Assistant and Homey Pro Smart Home hubs

Designed by SmartHomeGuys in the UK, the DeskUp Pro is an ESP32-based standing desk controller compatible with Home Assistant, Homey Pro, and other Smart Home hubs, using the desk’s standard RJ11/RJ12 connection. Many modern standing desks come with a controller from Jiecang or another company featuring an RJ12 port. The DeskUp Pro plugs directly into this port, draws power without an external USB supply, and bridges the desk’s controls to your 2.4 GHz Wi-Fi network. This allows you to automate your desk height, set health-focused standing reminders, or use voice assistants like Google Home and Alexa, all while keeping the desk’s original physical keypad fully functional. DeskUp Pro specifications: MCU – Espressif Systems ESP32-C6 or ESP32-S3 microcontroller with 2.4GHz Wi-Fi and Bluetooth LE Desk connectivity – Built-in RJ11/RJ12 cable for data and power USB – USB Type-C port for initial setup and firmware flashing Misc Supported Jiecang control boxes JCB36NE2 (used […]

Trail Mate open-source firmware leverages Meshtastic and MeshCore for ESP32 off-grid handhelds

vicliu624’s Trail Mate is an open-source firmware for off-grid communication and GPS coordinates sharing, leveraging the Meshtastic, MeshCore, and other projects, and designed for ESP32 handhelds such as LILYGO’s T-LoRa Pager or M5Stack’s Tab5 with a LoRaWAN module. The Trail Mate firmware provides a fixed north-up GPS map, direct LoRa text messaging through Meshtastic or MeshCore mesh networks without relying on a smartphone, and prioritizes stability, efficiency, and interoperability over feature density. Trail Mate user interface highlights: Simple main menu with four icons: GPS, LoRa chat, tracker, and system utilities. GPS map Fixed North-Up map orientation (no rotation) Fully offline map rendering from SD card tiles (png/jpg files) Three switchable base layers: OSM / Terrain / Satellite Optional contour overlay for terrain shape awareness Real-time position marker for the current GPS fix Discrete zoom levels optimized for embedded systems Simple breadcrumb trails for path awareness Fast in-page layer switching via […]

Open-source hardware DAB+ receiver combines ESP32 SoC with Skyworks SI4684 digital radio chip

When I wrote about a DIY ESP32-S3 internet radio last week, “raspbeguy” commented he’d rather choose an ESP32-based DIY DAB+ receiver kit, such as the one offered by the PE5PVB project based on a Skyworth SI4684 receiver. I first heard about DAB (Digital Audio Broadcast) in 2003 when we considered adding it to a CD player. It’s basically the digital equivalent of analog FM/AM radios, and I haven’t heard much about it since DAB and the “new” DAB+ standard are mostly a European story (see coverage map below). PE5PVB’s open-source hardware DAB receiver might still be worth a look. PE5PVB’s SI4684 ESP32 DAB+ receiver features: Controller – ESP32 microcontroller with WiFi and Bluetooth (DoIT ESP32 devkit v1) Storage – MicroSD card slot Display – Color LCD screen with 320×240 resolution (SPI) Audio 2x RCA connectors for speakers 3.5mm headphone jack with amplifier DAB+ receiver – Skyworks SI4684 loaded with DAB+ […]

Velxio is an open-source, self-hosted Arduino, Raspberry Pi, and ESP32 simulator

Velxio is an open-source, self-hosted simulator for Arduino, ESP32, and Raspberry Pi boards that works directly in your web browser. You can drag-and-drop boards, connect components and modules, write and run code in Arduino or Python, and access the serial console, all without hardware. If it looks similar to what the Wokwi simulator has to offer, it’s because Velxio was inspired by it and even integrates the AVR8 CPU emulator, RP2040 emulator, and QEMU fork for ESP32 Xtensa emulation from the Wokwi project. But the key difference is that Velxio can be self-hosted, although there’s also an online demo. Velxio currently supports 19 targets across five architectures AVR8 (ATmega / ATtiny) Arm Cortex-M0+ (Raspberry Pi RP2040) RISC-V RV32IMC/EC (ESP32-C3 / CH32V003) Xtensa LX6/LX7 (ESP32 / ESP32-S3 via QEMU) Arm Cortex-A53 (Raspberry Pi 3 Linux via QEMU) The project also offers 48 components. The developer mentions that additional features compared to […]

RuView project leverages ESP32 nodes for WiFi-based presence detection, pose estimation, and breathing/heart rate monitoring

RuView is an open-source “WiFi DensePose” implementation leveraging multiple ESP32 nodes to turn WiFi signals into real-time human pose estimation, vital sign monitoring, and presence detection without relying on video cameras. WiFi DensePose is a sensing technique, first explored in academic research, that leverages WiFi signals to reconstruct human pose. RuView implements this technique in Rust or Python, and relies on your WiFi router and several ESP32 nodes to track body pose, detect breathing rate, and measure heart rate even through walls. As we’ll discuss below, this project has its own controversy, as some claim it’s fake. The solution relies on Channel State Information (CSI) disturbances caused by human movement to reconstruct body position, breathing rate, heart rate, and presence in real time using “physics-based signal processing and machine learning”. That obviously means you need CSI-capable hardware, and not all consumer WiFi nodes implement it. The project description lists various […]

Ampisu Portable programmable lab power supply

Ampisu is a compact pocket-sized USB lab power supply with SCPI and web control (Crowdfunding)

The concept of a USB-C-based power supply is not new, and we have previously seen projects like XIAO Powerbread and Axiometa BrodBoost-C. As USB PD-based power adapters and power banks have become much cheaper, adjustable power supplies like the PocketPD and BenchVolt PD have come out. Both have their own limitation: the PocketPD has only a single output channel, thus hardly a lab power supply, and the BenchVolt PD is not quite compact enough to be considered pocket-friendly. This is where the Ampisu comes in. It’s a compact, pocket-friendly, and isolated three-output lab power supply designed to fit in a pocket and includes features of a typical full-sized power supply. It’s designed for low-power embedded work, field debugging, and automated test setups. Ampisu specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 125 MHz with 264KB SRAM Storage – Non-volatile memory for saving configurations Power Input 5V via USB Type-C port Automatically adapts to […]
