Doodles-as-A-Service Repo

👋 Aloha, this is where you can grab most of my tech doodles and sketchnotes.

I have been posting my tech doodles on Twitter and Microsoft open-source projects. I am repeatedly asked where to get the original images, especially from people who saw some of my works out of context on some social media, so I decided to put them all together on one GitHub repo.

Here are some of the latest digitally created hand-drawn doodles, as well as photos of analog ones.

All my doodles are under Creative a Commons license, so please share with attributions. And I definitely don't want you to NFT them without my permission (and I won't permit you because you don't own them. They are open-sourced to be freely available for educational purpose only!)

Enjoy 🌺

HTTP Status Cats 🐱

This is one of my first personal projects to make technology into cats. Although this is not doodling, I thought it was worth mentioning here!

All HTTP Cats are now hosted at HTTP.cat because the domain name is awesome.

All images (except a few) are originally created by me a decade ago! Read the story on Know Your Meme

Slack API Zine

/slack

└── 📁slack  
    └── 📄...

These are something I did while working at Slack. I created the zine (as physical printed books) to be distributed at Slack-sponsored events and conferences but never got fully approved. The global pandemic forced us to give up all in-person events anyway.

The content is outdated as of 2022 so view them with cautions.

🖨 Printing / TIFF

⚠️ Updated on August 27, 2021:

I no longer host the high-res TIFF files here because my Git LFS has been disabled as the bandwidth exceeded my data plan. Thank you! 🙇‍♀️

The tiff files are for printing. I set them in 5.83 x 8.27 inches, which should fit in A5 paper size. They are large files and stored as LFS files so you won't download the actual files when you git clone so please download manually from GitHub.
