Hello, everyone!
I've been trying to write my Gemini client for ESP32, and so far has
been extremely easy. Just wanted to know if anyone is building a
similar project.
And also, it would be nice to have some example requests/responses on
the protocol specification, or at least add some section in the main
{web,gem}site for that. What do you think?
Finally, it would be nice to have a CAPCOM instance to keep track of
Gemini-based projects around the Geminispace, I could even host it
myself, let me know if you think it's a good idea.

This is quite interesting, would you mind writing it up somewhere? What are you planning to use for input and output? I've been toying with the idea of building a low-power Gemini terminal to operate over a LoRa network, and ESP32 is one of the options I'm considering for the gateway. I haven't yet found a touch-screen display for the client that can be driven over SPI and supports 80 columns (e.g. 640px wide), at least not anything readily available. Kevin
Please do, I have a couple of ESP32s with a display which would be fun to make a Gemini client that advertises itself via the display and bluetooth with.

I'm planning to use the code for another project, with an E-ink display, keyboard and buttons. I wrote about it on my gemsite: gemini://avalos.me/articles/le-gemini-project.gmi Here's the unfinished code from my experiment: https://fossil.avalos.me/esp32-gemini On Thu, Aug 20, 2020 at 11:56:46PM +0100, Kevin Sangeelee wrote: > > I've been trying to write my Gemini client for ESP32, and so far has > > been extremely easy.

Kevin, This feather wing might be what you want. The screen is not touch but it comes with a kickass keyboard: https://www.tindie.com/products/arturo182/keyboard-featherwing-qwerty-keyboard-26-lcd/ I wanted to use this and an ESP32 (or the Giant Board with ARM) to create a small Gemini client but at the moment I can't really devote time to it.

Wow, that keyboard+screen is really cool! I want to order one, but only for this experiment project. The one I wrote on my gemsite requires extremely cheap components, so that they can be affordable for people with low income in areas without a lot of infrastructure.

The post linked below talks about basic accessible devices in terms of
sustainability, but I think the ideas are quite closely related to
your own. Essentially, it suggests that an existing ubiquitous source
of low-power networked computing is the plethora of Android phones in
circulation (that are only really made 'obsolete' for the purpose of
shareholder returns). It's quite a compelling case for applications in
which WiFi/GSM/Bluetooth/etc. is enough.

Tied with something like Deedum (https://github.com/snoe/deedum),
perhaps modified to support older hardware and to also support sync
for offline viewing, this would seem to be a big head start in
achieving your goal, albeit from a different direction.

> gemini://gemini.circumlunar.space/~solderpunk/gemlog/the-standard-sal vaged-computing-platform.gmi That Gemini link about `salvaged computing` is very interesting, it addresses several key problems with modern `sustainable` computing and I think it is indeed compatible with the concept and mission of my project. Thanks for sharing! > Tied with something like Deedum (https://github.com/snoe/deedum), > perhaps modified to support older hardware and to also support sync > for offline viewing, this would seem to be a big head start in > achieving your goal, albeit from a different direction. Honestly, I don't think Flutter is that suitable for salvage computing. First of all, because it relies on Google a lot. Also because it is not very efficient, especially the renderer, which requires a relative lot of GPU in order to work smoothly.

Hi Kevin, maybe the open book feather is also something for you: https://hackaday.io/project/168761-the-open-book-feather <https://hackaday.io/project/168761-the-open-book-feather> It?s based on Adafruit?s Feather and could be easily extended with wings (GPS, LoRA, WiFi, keyboard etc.).
