KLAXXON! #SOURCE issue 4 "Airwaves and Airplanes" is out! Good grief that's taken a while! Anyway in this issue we have a beginners tutorial for the fabulous @gnuradio we also get started with #OpenVSP which is #NASA's #opensource vehicle sketchbook and it's rounded out with a look at a new @FreeCAD workbench, Detessellate which helps reverse engineer Mesh to #CAD files. We've also tweaked a few things on the website! https://sourcemag.co.uk/
