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/

KLAXXON! #SOURCE issue 2 is now available for download! In case you don't know what I am on about SOURCE is my attempt at an #opensource "pay what you feel" magazine. In this issue we look at #Godot, #Inkscape, #OpenStreetMap #Logseq #Termux and #Syncthing

There's a little more info and a direct to pdf link on my blog as well as links to Issue 1 which was a deep dive on Computational Fluid Dynamics with #FreeCAD.

Something for the weekend? I'm super pleased to have just blogged with the 1st issue of #SOURCE. SOURCE is an idea for where to place articles I'd like to write but that are to difficult for my brilliant paid clients to home. SOURCE is opensource, free (pay as you feel) and I'd LOVE it if you shared my first experimental issue on Computational Fluid Dynamics with @FreeCAD that's on this blog. Ta.

A magazine style cover. Diagonally across the middle is an image from a CFD simulation of a Ballute parachute in a virtual wind tunnel created in FreeCAD and post processed in the opensource Paraview. The magazine/newsletter is called SOURCE and there are text details listing the issue number, the month and year as well as a line about how the contents are covering Computational Fluid Dynamics.
