An open-source robot vacuum you build yourself — Raspberry Pi, ROS 2, 2D LiDAR, Home Assistant, 3D printed chassis. No cloud, fully local.

oomwoo is early stage and building in public. The community can contribute modules in parallel — from SLAM navigation to dust bin design.

The GOWIN ecosystem continues to be adopted by the open-source FPGA community!

Support for GOWIN FPGAs has been added to the popular #fCAPZ FPGA debug toolchain!

fCAPZ is an open-source, vendor-agnostic suite of FPGA debug cores, including, among others, an Embedded Logic Analyzer (ELA) for waveform capture and an Embedded I/O (EIO) for runtime read/write of fabric signals. Coupled with OpenOCD, fcapZ opens up a new realm of debugging possibilities:

* No more fiddly, platform-specific, GUI-based configuration of debug cores.
* No more interrupted synthesis / PAR flow for debug core wire-up.
* Simple plug-and-play debug cores, platform-agnostic interface.
* Command line-based, i.e. probe, capture, with a multitude of debug options.
* Automated, AI-based review of debug capture
* Allows waveform review using open-source viewers such as Surfer or GTKWave.

For those wishing to see fcapZ in action, @BrisbaneSilicon has integrated it into the example project for their popular BRS-100-GW1NR9 FPGA development board!

The adoption of the GOWIN ecosystem by the open-source community is continuing, making FPGA access even easier.

Raspberry Pi 5から使えるようになった高速インターフェース、PCIeを知っていますか？⚡

PCIeの基本：
・CPU↔デバイス間の超高速データ転送
・Pi 5はPCIe 2.0 x1（最大5Gbps）
・M.2 HAT+を使ってNVMe SSDやAIチップを接続

💡 何が変わる？
・NVMe SSD → SDカードの10倍以上高速に起動
・Hailo-8L → リアルタイムAI推論が可能に
・USBとは桁違いの帯域幅

PCIe対応で、Raspberry Piが
「小さなPC」から「本格的なサーバー」に進化しました。

Espressif Systems tarafından üretilen ESP32 gibi çiplerde flash encryption, harici SPI flash içindeki firmware’i AES-XTS benzeri bir modda şifreleyip anahtarı eFuse içinde saklayarak, CPU’nun flash okuma sırasında donanımsal olarak otomatik decrypt etmesi prensibine dayanır; matematiksel olarak AES kırılmaz, ancak araştırmalar fiziksel saldırı modeli altında iki ana zayıflık sınıfı gösterir: birincisi yan kanal analizi olup, özellikle Correlation Power Analysis ile AES işlemi sırasında oluşan güç tüketim izleri üzerinden anahtar bitleri istatistiksel olarak tahmin edilebilir; ikincisi fault injection yani voltage glitch veya elektromanyetik hata enjeksiyonu ile boot ROM’daki secure boot ve anahtar erişim kontrolleri anlık olarak atlatılarak kontrol akışı manipüle edilebilir, böylece şifreli firmware’e dolaylı erişim veya doğrulama bypass mümkün olur; sonuç olarak açık, kripto algoritmasında değil, donanım uygulaması, boot zinciri ve fiziksel saldırılara karşı dayanıklılık katmanında ortaya çıkar.

[Mustafa @oprydai]

if you come from software, hardware robotics feels intimidating.

it shouldn’t.
think of hardware as software with physics attached.

start small:
power → batteries, regulators, current limits
actuators → dc motors, servos, steppers
sensors → encoders, imu, cameras
controllers → microcontrollers, motor drivers

map software concepts to hardware:
loops → control loops
bugs → noise, backlash, latency
crashes → brownouts, overheating

write simple firmware.
blink leds. spin motors. read sensors.
then connect it back to what you know:

run control code on real motors
stream data into ros
watch your “perfect” algorithms meet reality
hardware teaches what software hides.

start small. iterate. integrate.
