¡La residencia rural Compost Powered Dome de @victorjbarahona va tomando forma! ✨La propuesta consiste en la construcción de un invernadero que utiliza biomasa para generar calor. La intención es que esta estructura con forma de domo mantenga una temperatura templada y constante a lo largo del año, también en invierno, permitiendo así el cultivo de huerta de forma ecológica, y usando energías totalmente renovables 🌱🛖 Compost Powered Dome es una de las residencias Maker Ekintzaile 2025 impulsadas por Espacio Open. El proyecto se está desarrollando en un terreno de experimentación rural ubicado en Meñaka, Bizkaia, y los resultados se presentarán en noviembre, en el marco del festival Maker Faire Bilbao 2025 👀🚀—Victor Barahonaren Compost Powered Dome landa egonaldia itxura hartzen ari da! Biomasa beroa sortzeko erabiltzen duen negutegi bat eraikitzea da proposamena. Domo horrek urtean zehar tenperatura epela eta konstantea mantentzea da asmoa, baita neguan ere. Horrela, modu ekologikoan eta energia berriztagarriak erabiliz landu ahal izango da baratzea🌱🛖Compost Powered Dome Maker Ekintzaile 2025 egoitzetako bat da, Espacio Open-ek bultzatua. Proiektua Meñakan (Bizkaia) dagoen landa-esperimentazioko eremu batean garatzen ari da, eta emaitzak azaroan aurkeztuko dira, Maker Faire Bilbao 2025 jaialdiaren baitan👀🚀#espacioopen #makerekintzaile #fablabbilbao #egonaldiak

I'm working on this TRMNL eink display (esp32c3). I got it parsing out the JSON finally. But the way it works is it grabs a BMP pic and then displays it. I was getting a NetworkOther(embedded_io::Other) on reading the body. Thinking maybe I needed to mange my buffers a bit better. step by step lol
