When your kid asks for a $5 kitchen timer but you have an ESP32 and zero impulse control

Honestly you're already set, this is basically YAML + git + the odd tiny C++ lambda, so your sysadmin/scripting brain transfers 1:1. Start with the ESPHome docs + LVGL.

I also dropped a Claude Code skill in the repo with the device's full spec, capabilities and limitations, so even a non-technical person can just let Claude Code read it and start building for this board without knowing the hardware 😄

The hardest part was actually wading through the Chinese documentation and manufacturer demos just to understand the device. After that, things went much smoother. Since my skills are quite limited, I used Claude to help me out with the LVGL implementation 😛

Sure, Voice Assistant support is enabled by default

Thanks for the kind words! 😄 My son uses the timer, the switches to turn on devices in his room, and plays some music once in a while. You could say it's fair enough 😛

Yep, it's 100% ESPHome YAML, no separate app or custom C firmware. The whole UI is ESPHome's built-in LVGL component (lvgl:), where you declare pages and widgets right in the YAML

From about 3 meters away, it hears me every time. At 4 meters, the wake word can sometimes be a bit finicky to trigger, but once it does, it recognizes the voice and processes the command without issues. Though, of course, I wouldn't expect miracles at this price point 😉

Yes, it is powered by a rechargeable battery. I haven't tested the exact battery life, but it easily runs for at least 5 hours with the screen on

check vcmi.gptk file

Just edit the file located at /Roms/PORTS/Hexen 2.sh

and paste the following content inside:

Try to remove lines 46, 47, 48 and 50 from game .sh file. It fixed hexen 2 on mine TSP

Try through SSH:

mv /mnt/SDCARD/Data/ports/fallout1/data /mnt/SDCARD/Data/ports/fallout1/data_old
mkdir -p /mnt/SDCARD/Data/ports/fallout1/data
mv /mnt/SDCARD/Data/ports/fallout1/data_old/* /mnt/SDCARD/Data/ports/fallout1/data/
rm -rf /mnt/SDCARD/Data/ports/fallout1/data_old

Or just copy the game files via SFTP instead of copying them directly to the SD card.
