Open-source TS808-style overdrive pedal with switchable bass, treble, and clipping options, a custom PCB, and a 3D-printed enclosure. Includes complete design files and DIY documentation

Local-first PCB automation for KiCad with safe MCP tools and deterministic autorouting research.

Editable four-sheet KiCad schematic for a compact STM32-based synthesizer with USB-C power, controls, and an audio codec path, generated with SpeedUp for engineering review.

This project is a guitar pedal with analog circuits. It has a four-stage JFET phaser of the MXR Phase 90 type and a diode-clipping overdrive of the BOSS OD-1 type. The project includes an LTspice simulation and a KiCad PCB layout. The PCB has four layers and the correct dimensions for a 1590BB enclosure.

Stereo audio balance indicator with KiCad source and PCB manufacturing files.

Monophonic analog synthesizer featuring an AS3340 oscillator, LM13700 VCA, Teensy 4.0 USB-MIDI control, and adjustable analog attack/release envelope

Two-layer PCB implementing a JFET noise-gated distortion circuit in a 1590B enclosure. KiCad.

Low-noise 5 V electret microphone preamplifier with adjustable 30–40 dB gain, AD8656 analog front end, KiCad PCB design, and LTspice validation.

A pocket-sized offline MP3 player with a Tamagotchi-style monkey companion, built from scratch around a custom ESP32-S3 PCB as a one-of-a-kind anniversary gift.
