That laptop looks amazing! Monochrome LCD?

Looks like E-ink.
Is it all custom including the keyboard? What computer and OS is it running?

@a_corbin @jrsharp @tqw

You're right, I saw in another post that it was e-ink.
I thought it might have been one of those groovy Sharp mono LCDs like the Playdate uses.

@rl_dane @a_corbin @tqw hey all, thx for the kind comments! Yes, it’s eink and it looks great outside. I made it for walks in the woods. :D

@rl_dane @a_corbin @tqw oh, and the OS is a custom firmware based on the Zephyr RTOS. It includes a multi-transport 9P library (which powers the keyboard comms, notably) and sports an rc-like shell. #plan9 #inferno

@jrsharp @a_corbin @tqw

Daaaaaaaang, that's sick. XD

@rl_dane @a_corbin @tqw and now that I’ve got very serviceable gopher and telnet clients, it’s the perfect vehicle for navigating the #evensmallersmolweb. ;)

@rl_dane @jrsharp @a_corbin @tqw I opened it in Android thinking it would work 😔

@anon @jrsharp @a_corbin @tqw

I haven't tried the emulator on android, but the rest of the site (describing the laptop) is plain HTML.

@anon @rl_dane @a_corbin @tqw sry. I don’t really have a good android test setup.

@jrsharp @rl_dane @a_corbin @tqw I might have missed it, but is the firmware open source? Why did you chose Zephyr RTOS?

Show thread

Jon Sharp 3d ago

@ayba @rl_dane @a_corbin @tqw I chose Zephyr mostly because this is a microcontroller-based deck. It has an ESP32-S3. And Zephyr provided the LoRa driver, epaper driver, character framebuffer, etc. I started this firmware years ago, and Zephyr has only continued to mature and gain features — latest release now has WireGuard, so I’ll be rolling that into the firmware soon. :)

@jrsharp @ayba @a_corbin @tqw

Sick!!

Any plans for a basic web browser like w3m or lynx?

Also, does it have vi? 😅

@rl_dane @ayba @a_corbin @tqw it does have vi. :) I don’t have any plans for web browsing, actually. (I’m really pushing the limits of this 240Mhz Xtensa mcu). But I can report that my basic vt100 terminal support is enough to make w3m and lynx both work great when telnetting into another host. I draw inspiration from the Bell Labs Blit terminal.

@jrsharp @ayba @a_corbin @tqw

Funny how the Blit terminal reminds me a bit of the Vectrex. ^___^
