Haasoscope Pro open-source, real-time sampling USB oscilloscope supports up to 2GHz bandwidth (Crowdfunding)

Haasoscope Pro USB oscilloscope

The Haasoscope Pro is an open-source hardware, high-bandwidth, and real-time sampling USB oscilloscope. Building upon its predecessor, the Haasoscope, the new Pro model offers a bandwidth of 2GHz, 12-bit resolution, and a 3.2GS/s sampling rate. The Haasoscope Pro USB oscilloscope is “designed to be low cost, while maintaining super-fast performance.” While it only comes with 2 channels, the flexible design makes it possible to combine and sync multiple devices (using Cat5 cables) to double the sample rate or add more channels. The oscilloscope works with standard x10 passive probes but a custom active probe, the Haasoscope Pro-be, is also offered. It supports the full 2GHz analog bandwidth and is priced much cheaper than similar probes. The Haasoscope Pro USB oscilloscope’s high sampling rate and bandwidth make it ideal for radio frequency signal analysis and high-speed digital debugging. It is similar to the ThunderScope Thunderbolt and PCIe oscilloscope which offers more […]

Femtofox Pro v1 LoRa and Meshtastic development board runs Linux-based Foxbuntu OS on Rockchip RV1103 SoC

Femtofox Pro v1 kit LoRa and Meshtastic development board

The Femtofox Pro v1 kit is a compact, low-power LoRa and Meshtastic development board running Linux specially designed for Meshtastic networks. Built around the Luckfox Pico Mini (Rockchip RV1103) SBC, this compact development platform supports USB host/device functionality, Ethernet, WiFi over USB, GPIO interfaces, I2C, UART, and a real-time clock (RTC). The most unique feature of this board is that it operates at very low power (0.27-0.4W), making it ideal for solar-powered applications. Additionally, Femtofox supports native Meshtastic client control, USB mass storage, and network reconfiguration via a USB flash drive. It also includes user-configurable buttons for WiFi toggling and system reboot, enhancing its usability. These features make Femtofox particularly useful for applications such as emergency response and off-grid messaging.

LLMStick – An AI and LLM USB device based on Raspberry Pi Zero W and optimized llama.cpp

LLMStick

Youtuber and tech enthusiast Binh Pham has recently built a portable plug-and-play AI and LLM device housed in a USB stick called the LLMStick and built around a Raspberry Pi Zero W. This device portrays the concept of a local plug-and-play LLM which you can use without the internet. After DeepSeek shook the world with its performance and open-source accessibility, we have seen tools like Exo that allow you to run large language models (LLMs) on a cluster of devices, like computers, smartphones, and single-board computers, effectively distributing the processing load. We have also seen Radxa release instructions to run DeepSeek R1 (Qwen2 1.5B) on a Rockchip RK3588-based SBC with 6 TOPS NPU. Pham thought of using the llama.cpp project as it’s specifically designed for devices with limited resources. However, running llama.cpp on the Raspberry Pi Zero W wasn’t straightforward and he had to face architecture incompatibility as the old […]

SPOKE capacitive touch sensor board targets interactive computer interfaces (Crowdfunding)

Spoke capacitive touch sensor controller

SPOKE is a Raspberry Pi RP2040-based capacitive touch sensor board for interactive computer interfaces. It is designed to simplify the integration of touch-based control into various projects. SPOKE features up to 27 sensor inputs and can “turn almost any conductive material into a sensor” to control almost any computer input. Potential applications include music making, video game controlling, typing, and general software controlling. The board was designed by Tom Fox, an educator, maker, and musician in the UK. According to him, the board is accessible to beginners getting started with touch sensing while retaining enough power and customizability for professional use. It works with several conductive materials, including copper pipes, conductive paint, aluminum foil, pencils, conductive filaments, fruits, fabrics with conductive threads, and metallic surfaces. It can also be used with a non-conductive material (such as plywood) if a conductive material (e.g. tinfoil) is behind it. The fully-featured SPOKE capacitive […]

Raspberry Pi RP2350 board with USB-A port

Waveshare RP2350-USB-A is a small Raspberry Pi RP2350  board with a USB-C port for power and programming and a USB-A port to use the board as a USB device or host through a programmable IO (PIO) implementation. The board also features an RGB LED and two GPIO headers, which could make it useful for controlling GPIO/I2C/UART/SPI-connected devices when connected to a USB keypad or similar input. Alternatively, it could emulate a keyboard, mouse, or other USB device when connected to a host. RP2350-USB-A specifications: SoC – Raspberry Pi RP2350A MCU CPU Dual-core Arm Cortex-M33 @150MHz with Arm Trustzone Dual-core 32-bit Hazard3 RISC-V @ 150MHz Up to two cores can be used at the same time Memory – 520KB SRAM Storage – 2MB SPI flash for firmware USB USB Type-A port connected to GPIO12, GPIO13, 5V, and GND USB 1.1 Type-C port for power and programming Expansion – 2x 9-pin 2.54mm […]

Intel floats Modular PC design proposal for repairable laptops and mini PCs

Intel modular PC design

Intel has published an article proposing a modular PC design that would improve the repairability/right-to-repair of laptops and mini PCs and reduce e-waste through the replacement of motherboard, display, and M.2 or FPC add-on modules for the user-facing ports. Making repairable, modular electronic devices is not a new idea, and the Framework laptops are probably the best-known option now, but they do come at a premium. But most projects are limited success, for instance, Project Ara modular smartphone from Google eventually died off. We’ve also covered modular or open-source hardware solutions from smaller companies over the years such as Firefly Station P3D modular Arm mini PC with swappable cards, or Olimex Teres-I DIY and open-source hardware laptop. It’s good news that a large company like Intel is taking the repairable, modular PC topic seriously, but as we’ll see below it’s currently a high-level proposal with few technical details. Most laptops […]
