Welcome to my humble collection of free online tools, open source projects and blog.

ClearEvo online tools

A growing collection of handy tools that run entirely in your browser - open your MRI/CT scan CD (DICOM viewer), make a free QR code that never expires, convert MP4 to MP3, edit any file in a hex editor, convert GIS files (Shapefile, GeoJSON, KML, GPX), watch a Bluetooth/USB GPS receiver live, talk to serial ports and modems, and more. No install, no account, and your data is never uploaded (verify it yourself). Browse the tools collection

Bluetooth GNSS Android app

Connect Android phones to external Bluetooth GNSS receivers and use the received location via the mock location provider, with NTRIP relay for RTK on supported devices. Free and open source (GitHub). The app is no longer actively developed - its Rust GNSS parser lives on as the engine of the GNSS Monitor browser tool.
