Welcome to my blog!

Here, you’ll find posts on lessons I’ve learned, the things I find interesting, and what I am working on. Although I am not much of a writer, (really, it takes me a very long time to write together a post), it is an attempt to track my thoughts and share learnings through the years.

Although my interest is wide, you will most likely find contents regarding software and hardware development on this blog.

Feel free to scan around! If there is anything that may interest you, or if you have any questions, please feel free to reach out to me!

  • May 3, 2019 Sainsmart RYC GRBL V2 Upgrade
    GRBL has been optimized for Ardunio’s ATmega328p. So most configurations out there will use the Arduino Uno and a CNC shield. I decide to go with the Sainsmart RYC-GRBL-V2 hoping it would work out of the box. The reason why this is a long post is because it didn’t work out of the box. To get it up and running these are the list of things I changed to get it working.

  • Oct 1, 2019 Installing Linux on Pixelbook
    Understanding Linux # Kernel - Low level drivers that interacts with hardware Firmware Stuff # *Firmware Write Protect Firmware is stored on a special SPI flash chip and has a special register that sets the device to read-only. This change be changed by special hardware and software measures. The write protection of these chips are dependent on grounding a WP pin on the flash chip. Specific to chromebook models after 2017+ (CR50 models), the state of the WP pin is controlled by the CR50 with close-case debugging (CCD).

  • Oct 9, 2020 Ubuntu vs Arch Linux
    Goals # Been a long time Ubuntu user and like the interface. Nothing to really complain about. - want to see which is better as a learning platform - take this opportunity to struggle with Linux, configurations, and files - Learn to document process better Learning Objectives # better understanding of how Linux work concentrate on backend coding; closer to hardware programming Long term goals to learn about MCU and Computers for other technical projects Considerations # Looking for Vanilla Linux Windows Installation on Pixelbook Latest info for Chromebook and Windows here For Pixelbooks and Windows If on windows, will need a Live Linux USB to do the firmware update - Linux has access to the hardware Breakdown of Linux Distributions # Arch Debian Ubuntu - Debian unstable release
