StarFishDAQ
A general purpose data acquisition system and development platform.
The StarFishDAQ (or SFDQ for short) is a platform for developing MCU based hardware without having to start from scratch. It consists of hardware, firmware and software components. The SFDQ allows those projects that would otherwise use an off-the-shelf DAQ, PLC or MCU SBC to start with a stack of hardware, firmware and software. This allows more control, customization, and future applicability without sinking a ton of effort. The SFDQ can be used simply and quickly, as-is in... -

cosmic-dynamics-system
Programming Cosmic Dynamics A Practical Guide in 11 Popular Languages
NKTg Ground Vehicle A real-time robot vehicle controlled entirely by NKTg (mass-kinetic energy function) — physical sensors feed actual x, v, m, dm/dt data into the NKTg engine running at 100 Hz on an ESP32, which issues motor commands in real time. What This Is This is a hardware implementation of NKTg control theory — not a simulation, not a demo. The vehicle collects live sensor data, computes NKTg_1 and NKTg_2 on-chip, and drives motors accordingly — all without a host computer once... -
