USB/MIDI controller with isomorphic keyboard for music performance.
This project uses a sensory library to demonstrate local voice recognition on the STM32F746 board.
VU meter circuit lm3915 wiring diagram
Cochlear implants are a hearing solution for people with a moderate to profound hearing loss.
Arduino Car with Sonic sensor and Radio control Remote Control with LCD
With this Arduino source code, an ESP32 module, a power source and a standard microphone module, build a 96kbps WiFi Microphone with a WebUI
I designed this amplifier using TPA3116d2 ic and PCB is fully assembled by JLCPCB SMT assembly service. let's see the performance
Using low-cost components and a modular design, PolySynth aims at becoming your next audio engine for your upcoming project.
This is how to use IoT BASIC on Arduinos for a number of small projects. It is based on "BASIC on Arduinos" and extends the ideas there.
Hacked with ESP32 and Mongoose OS. Now it says welcome and unlocks the entrance door for you.
The amplifier described in this project is "Hybrid", but now the case is reversed and the Tube is used at the output.
It is fun to stare at the dancing lights and a great way to visualize music!
A 2x260W@4Ohm audio amplifier complete with a preamp and some basic digital controls/monitoring
Update December 2014: a kit containing all the circuit parts for this project is now available from Jameco Electronics.
Implements a wireless controller that takes signals from sensors and translates them into MIDI to control a software synthesizer.
Live bespoke effects manipulation from a Guitar Body using Arduino/Max4Live
MC3362 and ADF4351 based, modularized, NFM receiver. This receiver is designed to listen to the 2m band amateur radio conversations.
Audio spectrometer implemented on an LED Matrix with a BeagleBone.
Two way Audio intercom (walkie talkie) using M5Atom
A funky little retro looking LM386 mono amp to look good alongside the Bike Tyre Speaker and to 'Play It Loud'!
Build your own cool audio spectrum display with a Raspberry Pi.
A 32-channel RGB audio spectrum analyzer / visualizer driven by teensy 3.2 with FFT using WS2812B 32x8 RGB LED
I made an audio amplifier using a simple op-amp circuit that will be read using the STM-32 Nucleo.
Times how long you take to respond to the go signal. Uses 3x7 Segment LED displays driven by 3 4026B decade counters.
