#RaspberryPiZero2W

4 posts3 participants0 posts today

Històries de la vida a part, des que vaig tornar del TechGetTogether 2025, l'estaix que Trivago fa amb els seus IT, estic liat amb un projecte que em porta a la infantesa.

Sempre havia volgut tenir un R2D2, però sóc pobre i vaig tirar pel software i no per la branca de soldar components electrònics.

Al TechGetTogether ens van regalar a quasi tots una #RaspberryPiZero2W. Cansat d'instàncies sobre Docker i bots que publiquen a Mastodon, em vaig envalentonar i vaig comprar un e-Ink, un controlador de bateries, i una plaça de sensors, tots via GPIO HATs. He comprat també una matriu de 8x8 LEDs RGB i una controladora de so USB.

Estic picant un projecte en Python amb Speech-To-Text i Text-to-Speach, que envia el que dius a Gemini (El ChatGPT de Google perquè és gratis) i llegeix en veu alta la resposta, mentre el e-Ink i els LCDs mostren algo relacionat.

De moment tinc entrada de so, Gemini i e-Ink funcionant al Mac. A la Raspberry el e-Ink i el Gemini funcionen, i em falta probar el so i el dictat. Tot el reste està per fer.

Al final, haig de dissenyar i imprimir una carcasa xula, i haig de solventar el tema de la bateria, que per ara una de la mida ideal és només 1000mhA, que donen per UPS però no per mantenir el trasto funcionant ninguna hora. El tamany importa, però ja que la matriu de LEDs se surt de les mides de la Raspberry, igual m'animo i pillo una bateria potent a posar darrera dels LEDs.

Poca foto tinc del que hi ha fet, i ara mateix res de temps ni energia, però el projecte em té viciat per que dins la complicació, els resultats van sortint prou bé i entren ganes de més.

I ja, que ho volia vomitar. Més que res, per què ma mare em llegeix per aquí 😊

This handheld Linux PC is made for wireless hacking (Crowdfunding a Raspberry Pi-powered Flipper Zero alternative with a QWERTY keyboard)

The Interrupt is a handheld computer with a QWERTY keyboard for thumb typing, a 3.5 inch IPS LCD color display, and a Kali Linux-based operating system. But while you can use it as a general purpose device, it’s really designed as a sort of Flipper Zero-like system for tinkering with nearby wireless devices.

In addition to WiFi 5 and Bluetooth, the handheld has a CG1101 sub 1 GHz radio, […]

With a #RaspberryPiZero2W & #usbhub waveshare.com/wiki/USB_HUB_HAT possible to use 4 #lora #radio #rnodes at same #reticulum #meshchat interface. Can use 4 different sets of radio parameters at one #LoRa #radio interface. Can use 1 radio with low #spreadingfactor #sf for short transmissions at high data rate for large payloads like images or accessing #nomadnet #pages and 1 with larger SF for longer range. No need to choose between #meshtasic presets meshtastic.org/docs/overview/r ! just use them all ! Magic

#lora #radio #reticulum using #meshchat
If one #rnode (rnodeA) run by device A, e.g #RaspberryPiZero2W , has is its own #wifi #hotpot (as shown here loramesh.org/subpages/pi_insta) (with SSID & password),
& another rnode (rnodeB) run by another device B (any device with wifi) joins the hotspot (SSID & pwd),
& rnodeA & rnodeB both have the 'default interface' activated in their reticulum meshchat GUI,
the wifi hotspot *alone* (without radio) will enable sending messages via reticulum between A and B !

loramesh.orglora Mesh - raspberry Pi setup

Setup -> I have a #RaspberryPi #RaspberryPiZero2W running #linux #pios #RaspberryPiOS #headless

Aim: I want the pi to always offer a #hotspot #wifihotspot on #boot
based on the command

nmcli device wifi hotspot ssid pizerohotspot password my_password

Is this below a bad solution ?? -> I came up with this solution in the link below using a .service but fear it shows I am clueless? Is there a better way? Thanks!

I posted some notes on my personal blog about running #GoToSocial on a #RaspberryPiZero2W. Unlike my normal notes, this was not a how-to. This was just some general impressions. What were some of my adjustments for the platform, why I ultimately unplugged it... and why I don't think, at least in this generation of hardware, it's viable. #Fediverse #selfhosted #selfhosting #RaspberryPi #docker #podman

Notes from the Rabbit Hole · GoToSocial on a Raspberry Pi Zero 2 W: Will it work?A thread on the Fediverse infected my curiosity with the question: How small of a server can GoToSocial run on and still give a decent user experience for a single-user instance? Let's find out.
