Yongsup Park has created a high speed pulse counter using a Teensy 4.1 that is reliable down to an impressive 20 ns. The performance of this project is starting to rival equipment that costs significantly more than the powerful 600 Mhz Teensy 4.1 www.pjrc.com/high-speed-p...

Piotr Zapart has created another guitar pedal powered by the Teensy 4.1. The of the TGX4 was to create a nice set of guitar and bass tones while keeping the build simple and costs modest. He more than delivered with a sleek design that puts out great sound. www.pjrc.com/guitar-amp-m...
