I've uploaded my C/C++ (and MATLAB) Kalman Filter library as open source project to GitHub: https://t.co/jvG1D3zYhn

In particular the UDU formulation is fast, well suited for large systems and numerically very robust due to the UDU „square root“ decomposition.

Got Tetris running on a 26€ STM32F429 Discovery board emulating the Game Boy CPU and graphics on the ARM Cortex M4. Really fun project to hack together, and it’s open source—feel free to check it out here: https://t.co/erP3vjfS6R pic.twitter.com/pAbVwmCzIk

GPS (or better GNSS) positioning with Real-Time Kinematics (RTK) is certainly not new, but it still blows my mind how well it works. In the video cm-movements are being tracked by a u-blox ZED-F9P-04B receiver that I bought for €172: https://t.co/ztn1Ul4wbG pic.twitter.com/hmmAFow0p2

"Flip into the future": I've designed a NMPC to execute a flip maneuver with a simulated multicopter (16 motors, 800 kg).
The simulation is drawing the prediction horizon in blue (this is a bit jumpy as the flip has three different stages: climb, flip and return to home). pic.twitter.com/wNEzS8QL2f
