| This experiment clearly shows how much the enclosure can influence the sound of even a tiny and inexpensive full-range driver.

| No Thiele-Small data for this $2 driver, so the resonant frequency was measured at home with a signal generator, series resistor, and multim...

| This is a simple multifunctional device that, thanks to the high precision of the generated frequencies (with two decimal places), can succe...

| The CrowPanel 3.5" ESP32 proves to be an incredibly versatile platform for high-speed audio visualization. By combining custom FFT logic wit...

| Can a tiny $2 full-range speaker deliver surprisingly rich sound inside a miniature Fostex-style back-loaded horn? In this video, I build, t...

| A unique combination of astronomy, embedded programming and ambient lighting that transforms an ESP32-powered display into a realistic real-...

| Wi-Fi HaLow successfully bridges the gap between traditional Wi-Fi and LoRaWAN. In this test, an ESP32 camera streams real-time video to a H...

| These amplifiers prove that a well-designed and carefully built analog circuit can survive decades of hard use and still perform reliably.

| Boost converters replace the mains transformer here: 12 V goes in, 230 V comes out for the anode and 16 V for the heater. At maximum volume...

| Wi-Fi HaLow successfully bridges the gap between traditional Wi-Fi and LoRaWAN by combining long range, low power consumption, and enough b...
