Designer, technology enthusiast and licensed radio amateur, operating under the callsign MM7VXJ. 

This site serves as a record of my experimentation with radio telegraphy, electronics and other related projects.

I also create CGI animation as silico.studio and my 3D prints are avalable to purchase from physis.shop

Meshtastic
868mhz
Lilygo T-Echo 

    Meshtastic is a software platform which allows LowRa (Low Power, Wide Area) devices to create a mesh network, communicating on 868MHz (in the UK). The information shared includes encrypted text messages as well as GPS locations.

    We tested two Lilygo T-Echo devices, sharing telemetry and messages to a range of 2km. The theoretical range of these devices is limited by line of sight, so it is possible to make contacts much further.

    I hope to build a custom enclosure for a device using this platform and attach it to the dog's harness so that we can track him on GPS if he ever gets lost.
