Running a single CFD simulation rarely provides enough information to find a good hydraulic or aerodynamic design of a component. In many cases the poor engineer has to wrestle an awfully long list of design parameters into a state-of-the-art shape. Luckily, OpenFOAM and DAKOTA together provide an almost ready-to-use solution just for that: Sensitivity analysis(long […]
I’m building a wind turbine and as you might imagine, the blades are Ye Royale Paine In Me Buttocks. Too big for a CNC, too exposed for a 3D print, too complicated to be made by hand. I decided to make blades from pipes. This simplifies the build but now how do I know how
All OpenFOAM tutorials have Allrun and Allclean scripts which call some mysterious RunFunctions from even more mysterious sources. The most mysterious thing of all this is how poorly those are documented. Since those are not a big deal, I decided to jot down some remarks so a newcomer can tell what they are for. The
A cheap way to add custom buttons to your PC with STM32 and AHK.
Everybody said: “why don’t you just buy a new radio with bluetooth?”. And you can be sure when I say, that I considered this option several times, in fact, almost every day when something didn’t work. But, projects just wouldn’t be fun if everything would work out of the box. This is going to be
I am not going to share my negative opinion on visual aspects of design of this vehicle (although I could be very verbose) but there are some technical issues I need to clarify. There are statements in style of “Tesla Cybertruck could be insanely aerodynamic” or “Tesla’s Cybertruck Aerodynamics Do Flow Smoothly” or even nonsense
Serial Tool v2 released! Awesome new features that every developer need while interfacing with serial communication.
I occasionaly write scripts for geometry optimization, therefore I have to wrestle with geometry. Graphically very easy problems become Ye Royale Paine In Ye Buttocks to solve analytically. At first I wrestle with piles of points, lines, determinants, trigonometric functions and whatchamacallits. Then replace all of that with a few points and vectors. Here are
