StampFlyが初宙返りした日

Open-source, self-hosted Arduino, Raspberry Pi, and ESP32 simulator. cnx-software.com/2026/04/04/… Like the Wokwi project, Velxio simulates popular development boards right in your web browser. But the difference is that the open-source project can be self-hosted, running on your own machine. The project currently supports 19 boards and 48 components. Other highlights include support for multiple boards (e.g., Arduino connected to ESP32) and full QEMU emulation support for ESP32 and Raspberry Pi 3 (Linux).

Pyrite is a natural Schottky diode.

ESP32P4、「360MHzデュアルコア 16MBフラッシュ 32MB RAM＋USB2 OTG対応＋H.264ハードウェアエンコーダー」で2,200円とかいう狂った価格設定しててヤバい ヤバすぎてとりあえず2つ買った

.@Raspberry_Pi introduces 3GB RAM version of the Pi 4 for $83.75, and further increases pricing for 4GB RAM models. cnx-software.com/2026/04/01/… That now means a Pi 4 4GB goes for $100 and a Pi 500 Keyboard PC for a cool $410. Check the article for details.

Hi all I'm currently no long employed by Linaro and am actively looking for work. For the last few years I've been working on development of the Linaro Automation Appliance hardware, from prototype to final product. If you are looking for Product Design Engeneer hit me up.

Breadboard computer in the flesh!!

Is it acceptable? 😃

It's actually OVER for any PCB milling software, they all SUCK! I put the nail in the coffin by adding v cuts and trace selection. Next up is double sided boards and alignment holes. Never again will you suffer to make a PCB at home! pcbmiller.com OPEN SOURCE AND FREE

🤔KiCad 10 is here — how to keep your projects compatible? NextPCB has developed the KiCad Version Converter to help engineers collaborate smoothly across mixed-version environments. You can now downgrade schematic files, PCB layouts, symbol libraries and footprint libraries in seconds with this simple tool. 🔥Features: • Freely downgrade KiCad files from 10, 9, 8 to version 9, 8, or 7 • Automatically remove elements that break compatibility • Supports multi-file conversion • No uploads — everything runs locally in your browser • Includes a detailed change log for every conversion 👉 Try it here: nextpcb.com/kicad-version-co… 🙌Built for the KiCad community NextPCB is committed to supporting the KiCad community @kicad_pcb with tools that help make open-source hardware design smoother for everyone.

Just merged my DSI driver for STM32H7 into Embassy. Here’s a mock display using @ratatui_rs and mousefood rending into an SDRAM framebuf.

Ok this might be the best solder job I’ve done yet 😍

Open-source hardware @MicrochipMakes ATTiny1616 board that's about the size of a USB-C port. cnx-software.com/2026/03/26/… The tiny AngstromIO board is powered via USB-C and features two RGB LEDs and solder pads for GPIO, I2C, UART, and UPDI interfaces. The board is programmable with the Arduino IDE, but requires an external programmer board since the USB-C port does not carry data signals. "Dieu-de-l-elec" also designed a CH32V003 board whose design is shared in the same GitHub repo.

We started our journey as a precision robotics company with a clear mission – advancing industrial automation to the microscale. This video highlights one of the key requirements for making that mission possible: repeatability below 1 micrometer. #robotics #robotarm #engineering

BOOM!! Even more improvements to PCBMiller! It can now handle all operations, multiple bits, with built in pauses and instructions. It even tells you what size drill bits you will need! All of this is 100% free and open source, no more trash CNC software for making PCBs.

Prototypes of the ARK 12S CAN ESC are on the way! Trying out these low profile solder in standoffs for a solder-less assembly. Can be used with screws or soldering.
