BioAmp EXG Pill board enables ECG, EMG, EOG, and EEG biosensing (Crowdfunding)

BioAmp EXG Pill is a small Analog Front End (AFE) biopotential signal-acquisition board designed to be interfaced to any 5V MCU board with an analog-to-digital converter (ADC) such as most Arduino boards, or through a dedicated 5V ADC like the Texas Instruments ADS1115. The board can record biopotential signals like ECG (electrocardiogram), EMG (electromyography), EOG (electrooculography), and EEG (electroencephalogram), or in more simple terms, biosignals from the heart, muscles, eyes, or brain activity. BioAmp EXG Pill key features and specifications: Compatible with any 5V MCU with an ADC Biopotentials: ECG, EOG, EMG, and EEG (configurable) No. of channels: 1 Electrodes: 2 or 3 (configurable) Input Voltage – 5 – 40 V Input Impedance: > 35 MΩ Dimensions – 25.4 x 10 mm OSHWA certifications – IN000026 The board is open-source hardware and you’ll find KiCAD hardware design files like schematics and Gerber files on Github where you’ll also find several […]

PineNote is a community supported 10.3-inch e-Reader based on Rockchip RK3566 SoC

We’ve covered several e-readers in the past, but the PineNote 10.3-inch e-reader will be a bit different, as the hardware & software will be entirely developed by the community like other Pine64 platforms such as Pinebook Pro, PineCone, Rock64 single board computer, etc… Based on the Rockchip RK3566 quad-core Cortex-A55 processor, PineNote will be one of the fastest e-readers on the market, and leverage the code already written for Quartz64 single board computer, including mainline Linux support. PineNote (preliminary) specifications: SoC – Rockchip RK3566 quad-core A55 processor with Mali-G52 EE GPU, 0.8 TOPS NPU (AI accelerator) System Memory – 4GB of LPDDR4 RAM Storage – 128GB eMMC flash Display – 10.3-inch panel with 1404×1872 resolution (227 DPI), 16 levels of grayscale, front light with cool (white) to warm (amber) light adjustment, capacitive glass layer for finger touch-based input, and a Wacom electromagnetic resonance layer (EMR) for EMR pen input.

Debian 11 “BullsEye” released with Panfrost & Lima GPU drivers, exFAT support, driverless printing

Debian 11 “BullsEye” has been released with Panfrost & Lima open-source drivers for Arm GPUs, in-kernel exFAT file system, driverless printing, and many more updates, plus a 5-year support window. Debian’s release is significant as the Linux operating system serves as the base for Ubuntu and derivatives, Raspberry Pi OS, and together with Ubuntu, is one of the operating systems supported by Armbian which offers images for a range of Arm-based single board computers. Arm Mali GPU support in Debian 11 I remember a few years ago 3D graphics acceleration on Arm boards was news, as it was quite a challenge to get it working due to binary blobs. But Debian 11 now comes with Mesa 20.3 framework which includes Panfrost and Lima open-source Mali GPU drivers by default, as well as the Vulkan 1.0 conformant V3DV driver for Raspberry Pi 4. As noted in the documentation that means the […]

Xiaomi CyberDog quadruped robot is based on NVIDIA Jetson Xavier NX

We’ve previously written about consumer-grade smart robotic dogs selling for several hundred dollars with Petoi Bittle equipped with Arduino & Raspberry Pi, as well as XGO Mini Pro with Kendryte K210/K510 AI processor. Xiaomi has now launched its own quadruped robot that looks like a dog with the Xiaomi CyberDog equipped with a more powerful NVIDIA Jetson Xavier NX system-on-module (SoM), a larger and heavier body than competing consumer models, and a price tag of a little over $1,500. Xiaomi CyberDog specifications and key features: SoM – NVIDIA Jetson Xavier NXwith an hexa-core NVIDIA Carmel 64-bit Arm processor, a 384-core NVIDIA Volta GPU with 48 Tensor Cores, 2x NVDLA deep learning accelerators delivering a total of 21 TOPS at 15 Watts, 8GB RAM. Storage – 128GB “near” industrial-grade SSD Xiaomi’s in-house developed servo motors offering Maximum torque – Up to 32N·m Rotation speed – Up to 220Rpm Maximum speed – […]

Arduino programmable wireless multitool offers color display, touch controls (Crowdfunding)

QUARK may look like the perfect weapon to hijack a plane, but instead, it’s an open-source, Arduino-based wireless multitool for hardware engineers equipped with a full-color screen and touch-based controls. Based on ESP32 WiFI & Bluetooth wireless SoC, Mulin Group’s QUARK is an ultra-portable multimeter, signal generator and oscilloscope, a bit like IkaScope WiFi Pen-Oscilloscope, except having a laptop or phone to visualize measurements is only optional. The company also compares it to DT71 smart tweezers which do not have an oscilloscope function due to the tiny display. QUARK features & specifications: WiSoC – ESP32 dual-core processor with WiFI & Bluetooth connectivity Display – 240 x 134 IPS display Measurements Voltage – 0 to 26 V Current – 0 to 3.2 A Resistance from 0 to 2 MΩ Capacitance from 2 pf to 1000 uF Inductance up to 1 H Sampling rate for oscilloscope function – 400 ksps Features – […]

Mali-G78 GPU’s Valhall instruction set documentation released after reverse-engineering work

Collabora has been working on Panfrost open-source GPU driver for Arm Mali Bifrost and Midgard GPU for several years, and even getting official support from Arm. But apparently, that support does not include documentation for Mali-G78 GPU and other recent Arm Valhall Mali GPUs, as the company recently reverse-engineered Mali-G78 for about a month before releasing the documentation on the Valhall instruction set (PDF). Other results from the reverse-engineering include an XML architecture description that can be parsed by programs, as well as a Valhall assembler and disassembler that were used as a reverse-engineering aid. Besides Mali-G78 “Borr” GPU, the work will be useful for other Valhall GPUs include Mali-G77 “TryM’, Mali-G57 “Natt-A/B”, Mali-G68 “Ottr”, and Mali-G78AE “Borr-AE” for automotive & industrial applications. Alyssa Rosenzweig explains Collabora’s work that was based on the International edition of the Samsung Galaxy S21 phone powered by Samsung Exynos 2100 system-on-chip with a Mali-G78 […]

Cynthion board enables USB Hacking through Lattice ECP5 FPGA (Crowdfunding)

Update 16/02/2023: The LUNA board has been renamed to Cynthion, but the gateware framework continues to be called LUNA. Several USB hacking/debugging boards were launched in 2020 either based on microcontrollers or FPGA with the likes of Tigard (FTDI FT2232HQ), Ollie (STM32F042), Glasgow Interface explorer (Lattice Semiconductor iCE40), or Protocol Droid (STM32). All those were launched on Crowd Supply, and there’s now another one with LUNA “multi-tool for building, analyzing, and hacking USB devices” based on a Lattice Semiconductor LFE5U-12F ECP5 FPGA that raised over $100,000 in a few days. Cynthion hardware specifications: FPGA- Lattice Semiconductor LFE5U-12F ECP5 FPGA with 12K LUTs System Memory – 64 Mbit (8 MiB) RAM for buffering USB traffic or for user applications Storage – 32 Mbit (4 MiB) SPI flash for PC-less FPGA configuration USB – 3x High-Speed USB interfaces, each connected to a USB3343 PHY capable of operating at up to 480 Mbps.
