The Electronics

I’m using a simple sound-activated LED circuit, powered by an 18650 Lithium Battery charger/boost module that provides a 5V output.

The Schematic

Construction

Attaching the LEDs in parallel inside the guitar body..

build_led_insert

the sound module is built on a small piece of protoboard, with the electret mic poking through the “speaker”.

build_sound_module

With everything installed, including the 18650 charge/boost module and a power switch on the side. The micro USB connector for charging the battery pokes out the side of the enclosure.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
