The main site is an interactive BIOS-setup-style page that needs JavaScript. Everything on it is also available as plain HTML and Markdown:

## Pages

- [MetalBird: STM32F411 flight-controller PCB + bare-metal ARM firmware](https://rajveerchaudhari.com/projects/metalbird/): MetalBird: a drone flight controller Rajveer Chaudhari designed in KiCad, had fabricated, and is bringing up with hand-written Cortex-M4 assembly (clocks, USART, I2C, MPU-6050). No HAL, no RTOS.
- [PenguOS: 32-bit x86 operating system from scratch](https://rajveerchaudhari.com/projects/penguos/): PenguOS: Rajveer Chaudhari's x86 OS with its own two-stage bootloader, paging, drivers, preemptive threads, VBE graphics and a software 3D renderer. Boots in the browser.
- [Linux kernel patches: 4 commits in mainline](https://rajveerchaudhari.com/projects/linux-kernel/): Rajveer Chaudhari's Linux kernel work: 4 commits in mainline Linux (IIO adxl313/adxl372 guard(mutex) conversions, staging most cleanups), plus patches sent to linux-iio, linux-crypto and linux-media.
- [Debug logs: firmware and OS bring-up bugs](https://rajveerchaudhari.com/projects/debug-logs/): Bring-up bugs from MetalBird and PenguOS, written up by Rajveer Chaudhari, and how each was tracked down: STM32 flash-line timing masking an RCC errata, proving an MPU-6050 was dead, and a read-only BIOS shadow.
- [Whole site as plain HTML](https://rajveerchaudhari.com/classic/): every project, the kernel patches, debug write-ups, skills and education on one page.
