Looks beautiful. Very well done. Love the housing as well.

I suggest revoking your google macros API token and creating a new one, and changing your wifi password.

Can you explain why?

They'd previously committed those items, and since removed them, but once anything is pushed to a remote git repository, it is viewable in the git history even after being removed.

This looks so retro, I love it. The Japanese matches too in terms of vibe. Looks like something you'd see at a Japanese office in the 80's.

This looks really cool! I love the idea!

I checked out your GitHub repo and noticed you're using a 7.5-inch e-ink display. I'm curious, does it need to stay plugged in, or can it run on a battery? Have you tested the power consumption or battery life?

Also, are there any other case designs available? I really like the concept, but I'd prefer a slightly different look haha.

Great project!

I really like the design! Are you planning to make more case designs in the future? I like the idea, but Iā€™m curious if there will be different styles available.

If you pair the display with an ESP32 it can run for months on a single battery charge.

u/Haunting-Specific-36 1h ago

Thanks! I was wondering, with ESP32 + e-ink, is it mainly used for simple information like calendars/weather, or can it also display things like stock prices, custom dashboards, or photos? I'm thinking about a small e-ink display for personal use.

That looks really clean and clear!

What size screen did you use?

2

u/Noh_Jiu 21h ago

I used 7.5 inch display

u/HuyFongFood 14h ago

Awesome! I have a spare 7.5" display that I've been playing with. I'll have to pull it out and see what I can come up with :)

Why so bulky? What else is housed in the enclosure?

u/Noh_Jiu 1d ago

Just raspberry pi pico. The button is attached at the pico's shield, so I had to make bottom part bulky.
