👋 Hello Fosstodon!

Just joined this amazing FOSS community!

I build open-source hardware security devices. Currently working on SecureGen - a hardware TOTP authenticator and password manager on ESP32 T-Display.

🔐 What it does:
- Generates 2FA codes (like Google Authenticator) on dedicated hardware
- Encrypted password manager with BLE keyboard

I have two small #ESP32 dev boards with OLED. They seem to be Heltec WIFI LoRA 32 V1.x boards.
I can’t find them on the manufacturer’s websitite anymore.
https://heltec.org/ (v2, v3, v4 look similar, but are different.)

Only board info I can find
https://www.tha.de/~hhoegl/iot_workshop/docs/2_Heltecboard_V1.html

Could I maybe use them for #Meshtastic or #Meshcore?
So far, no luck getting any firmware to work. Flashing works correctly though. Just doesn’t seem to match the hardware.

Or is it not worth trying with these relics?

Wer seinen Roboter nicht entsorgen und durch ein teures Neugerät ersetzen möchte, findet im Open-Source-Projekt neato-connected einen interessanten Ausweg, das allerdings einiges an Wissen erfordert.

Wondering if fedi has any DIY indoor air quality/co2/voc/temp/humidity device recomendations?

I found this project, checks all the boxes + cute compact design, but sadly no longer maintained... I'm hesitant to order parts/PCB.

This tiny custom ESP32-C3 board is about the size of a USB-C connector (and is attached to one). Other features include a 32-bit RISC-V microcontrollers, WiFi 4, BT 5.0, and a single GPIO pin. It measures just 9.85 x 8.45mm. https://www.cnx-software.com/2025/11/21/ridiculously-tiny-esp32-c3-board-features-usb-c-one-led-and-a-ceramic-antenna/ #pegorKF32 #ESP32 #DevBoard

#MeshTNC #devlog

Working on BLE packet sniffing and transmission for MeshTNC, bc who doesn't want to do APRS or meshcore over BLE advertisements 😉

My quick hack feels promising so I think I'll clean this up and PR it.

Here I was thinking the KISS protocol support was going to be hard ✨

Actually this flew together, mostly bc @meph already did all the hard stuff on KISS handling.

So just check which output mode we're in and yeet the data at the BLE data KISS port.
