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 […]
Problem Few years ago I started with Keil + STM32 dev boards. Than STM32CubeMX was released and I started using it, generating Keil project as output. This was good enough for a couple of years, until Keil free version code size limit became a problem. Than I discovered VS Code editor and with a little effort,
UPDATE (29.12.2021): after a couple of weeks of testing, I can confirm that all he things covered in this project are now replaced (and even better) with VS Code Makefile tools plugin. Anyway, 3 years in a such rapid changing SW development world, I consider this project a success, even though closed. This is
variable: variableType = … The Problem I’ve recently switched job and I was “thrown” into a large project(s) based on Python. I had to implement only a few simple functions, but since I was/am a newbie there, this task wasn’t so easy. The problem was, that we use a giant custom “library” – numerous files,
Merging Files If you’re using SALOME to create STL files for meshing you can only save separate surfaces to separate files. That’s not a problem if you’re using snappyHexMesh but cfMesh only takes an STL file that has all surfaces combined and named. I wrote a simple Python script that does that for you. Save
There are numerous RC filter pole calculators online and I happily used them for a quick calculations while DIYing. The problem is that these online calculators calculate frequency pole where gain decreases by 3dB, which is fine, but what if you need to know the frequency of some (first-order) filter while given only the specifications about
The Problem: Path optimization The exact origin of this problem is somewhat blurry but since I already have the solution I won’t put much effort into clarifying it. We have a particle that moves along a spatial curve, starting from point r1 with a defined velocity of v1 and ending its path at r2 with
I build a Serial Tool for developing serial communication and custom protocols. Than I wish to share it with my friends and than there was a problem. Originally, Serial Tool was written in python v2.7 and pyqt4. My first windows distribution was created with py2exe with no problem. I followed simple online tutorial and voila, there it
