Swift
– an autonomous system developed by the University of Zurich’s Robotics and Perception Group.

] | [mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 chip that boosts the measurement range
up to a full 30 MHz.
That makes it a perfect tool for working with radios in the HF range.
