The #TDeckProMax just made my wish list, and that #TEchoCard looks like a nice rear view mirror ornament too.

Week-long battery life?! 🤯 The LILYGO T-Echo Plus packs a massive 2400mAh battery into a rugged design with handy extras like a carabiner hook. Same core functionality, just seriously upgraded! Check it out 💻 #Lilygo #TEchoPlus #IoT

After testing 7 #LilyGO #TBeamSupreme units, one thing is clear:

👉 Magnetometer calibration is not transferable between devices.

Even in similar environments, raw readings varied dramatically between units. Proper calibration isn’t optional—it’s per-device.

I also looked at how #Meshtastic handles the onboard #QMC6310… and it essentially doesn’t (no heading, no calibration).

Melody Machine firmware transforms LILYGO T-LoRa Pager into a portable MP3 player and Internet radio

Melody Machine is an open-source firmware that converts the ESP32-S3-based LILYGO T-LoRa Pager into a portable MP3 player and internet radio rather than a LoRa-based messenger running Meshtastic or Meshcore. Highlights of the Melody Machine firmware: LVGL-based graphical user interface with four themes WiFi Manager — Non-blocking WiFi with network list, password entry via on-screen keyboard, and auto-reconnect MP3 playback from SD card with folder browser, shuffle, repeat modes, and seek Internet Radio via M3U over WiFi (ICY metadata support) Seek — rewind / fast-forward MP3 tracks with the rotary encoder (±5 s per step) Dual-core audio/task design MP3 decoding runs on Core 0 via FreeRTOS UI and WiFi manager on Core 1 Settings — Saved as JSON on SD card in /melody_machine/settings.json; survives reboots and reflashes Auto power-off - Configurable idle power-off timer: 15 minutes to 2 hours The rotary encoder and built-in keyboard allow plenty of controls: Rotary

Do you feel like your mesh firmware on Lilygo T-Deck is slow because of hardware?

It isn't. This is T-Deck running a realtime calculated dodecehedron with glenz filling. No video, all done on the hardware.

A very capable hardware if you do it right.
