What this episode covers

The host reviews Red Pitaya's STEMlab 125-14 and MIKROE Click Add On Shield, describing the FPGA-based board as a versatile 'Swiss Army Knife' for engineers that can function as an oscilloscope, logic analyzer, or software-defined radio. Guy Dupont’s Autotuned Kazoo project is highlighted, featuring an ESP32-S3 and MEMS microphone to create a wireless MIDI controller and synthesizer using a sawtooth wave trick. Robin Mitchell’s Electromaker Educator segment demonstrates a voice-controlled Lego Planetarium upgrade using an Arduino Nano 33 IoT and stepper motors, while Wiznet’s announcement of the W55RP20 chip combining an Ethernet controller with an RP2040 is also noted.
