I lost some time figuring out how to associate “.stl” extensions with Slic3r. Gnome wrote a good documentation but it is not obvious to find. I did not use the package manager for that because I wanted the up to date AppImage.

I am currently working with BLE beacons -only iBeacons for now- with Espressif’s esp-idf libraries. The aim is to use the ESP32 as a gateway to published detected beacons to an MQTT broker. It was surprisingly easy and I will write something about that when the code will be more polished.

Anyway, by curiosity and to speed up development, I wanted to try microPython port to ESP32, and I did. Unfortunately, BLE support is not yet reliable enough and a lot of advertisements were lost with 4 to 6 beacons. This post is to keep track of my work and, hopefully, use in the future when microPython port will be more reliable :-)

I recently wanted to setup a repository for some custom OpenWrt packages for Respeaker. It seems that it is not so well documented, or at least, I did not found it and I have been helped on OpenWrt forum. Also, it is better to sign packages so…here we go!

Step by step guide to do a custom USB HID device on STM32 using ST CubeMX. There is already one page addressing it but without any details for beginners.
I will use my custom board based on STM32L0, but any Nucleo can be used by wiring a USB cable to 5V, GND, USB_D+, USB_D-.
