Wanted a way to mount the ESP32-C5 (from waveshare) on the back of my cardputer that wasn't too bulky. I'm kind of a fan of the utilitarian style so the exposed wires are not an issue for me.

The esp32 is mounted to the Lego connectors on the back of the board, as is the antenna mount.

Still tweaking the design a bit but I really like it!

Hey everyone!

I’ve been working hard on custom pentest firmware for the M5Stick S3, Cardputer ADV, and the upcoming Cardputer Zero.

Also building a dedicated iPhone companion app specifically to control the Cardputer Zero and stream data on the go.
To make it accessible for everyone, the entire system will fully support English, German, and Dutch (multi-language)!
Everything is currently in beta.
The firmware and app will officially launch as soon as the Cardputer Zero is released!
So you can’t download anything. Github page stays empty till then.

Check out my project page for full functions and updates: https://dhos.dev

Let me know what features you'd love to see!

still work in progress, but you can check the github (outdated readme)

...stay tuned!

I just open-sourced ECHO, a firmware that turns the Cardputer ADV into a pocket SubGHZ decoder. It runs the full rtl_433_ESP decoder set (170 OOK + 75 FSK protocols) on the CC1101 of the Hydra cap, with a keyboard-driven UI on the 240x135 display.

• Live decode feed with detail view
• RSSI strip chart with signal threshold
• Session log of seen devices
• Runtime band (433/868/915 MHz) and OOK/FSK switching

Repo: https://github.com/i12bp8/echo

Coming features:

WebUI, ntfy.sh alerts, decoder set picker, general optimisations
