Explore Samsung TV audio amplifier built around TAS5749M by tracing its circuitry and turning a discarded board into reusable audio platform
A Raspberry Pi HAT with a 15-band hardware EQ and browser control — no app, account, or cloud required.
Class D amplifier with a good performance and better sound quality. We can call it a Class D with Class A specs.
The simplest way to make a relatively powerful stereo Vacuum Tube audio amplifier with components that are easily available.
This ECC83 (12AX7) preamplifier project successfully delivers the warm, pleasant, and dynamic sound characteristic of vacuum tubes.
This project perfectly fuses the iconic Winamp software with modern Raspberry Pi functionality
Control BASS, TREBLE, MID and VOLUME with a lot of equalizer modes, all in a small PCB with WIFI, include PCB and code.
Convert text into real speech using Raspberry Pi Pico W, Wi-Fi, and the Wit. ai cloud TTS API.
Quickly explore a variety of op amp configurations on a small PCB with solderless component headers, supply rails and a signal generator.
Using an ESP32, WizNet 5500, SD, PoE and a Ti TAS5760L Amp, I built a Unify AI Horn alternative, a weatherproof audio announcement system.
In this project, I convert a classic PCL86 single-ended tube amplifier design to operate with the less common PCL82 vacuum tube.
Build a compact two-channel audio amplifier around the classic Toshiba TA8211AH and use an ESP32 as a simple audio test source. This project
These amplifiers prove that a well-designed and carefully built analog circuit can survive decades of hard use.
Build a compact dual-channel analog front end using OPA2320 to condition sensor signals before MCU ADC conversion.
Build a practical microwave RF test bench around the Mini-Circuits ZVE-3W-183+ high-power amplifier. The project combines a 5.9–18 GHz signa
