Sound controlled LED light show for your Xmas tree. An STM32 microcontroller takes instructions from a PC via Bluetooth and animates the LEDs. This is my Christmas tree, it has over 400 lights (exactly 404) that are all individually controlled … Read more
Here’s a fun project in the Christmas spirit. It’s a “Jingle bells” playing card, with the specific notes being signaled via LEDs as they are being played. We have 9 control lines for the LEDs and 1 line for the … Read more
This 5x5x5 LED cube uses a microphone and op-amp to react to sound. It’s run via an Atmega328P with an Arduino bootloader: ok, it is nothing new and far away from well done.. But its just amazing for me to … Read more
Viktor made a sound trigger for his DSLR camera: Now that I can take pictures of lightning I decided that I also want to be able to trigger my camera with sound. An op-amp filters and amplifies a microphone signal. … Read more
The Milkymist™ is an open source sound visualization tool. Its said to be one of the fastest open source systems on a chip capable of running uClinux. It features the LatticeMico32 processor core on a Spartan-6 FPGA (XC6SLX45). The project … Read more
The eight-core Parallax Propeller is capable of some pretty amazing things. One use developed by Johannes Ahlebrand is to emulate the famous Commodore 64 sound chip. His SIDcog V 1.0 code object allows the Propeller to accurately emulate an original … Read more
