Audio Electronics

In the summer of 2025 I started experimenting with small audio signal electronics.
How I started

• Coppersound
• JHS

Here's what I've built:

Current & Finished Projects

• Pedal Board Oscilloscope
• Cat Food Boost/Distortion 
• Transformer Boost
• Candle LED Distortion
• Candle Optical Tremolo
• Candle Optical Compressor
• Effects Loop Clean Blend
• Analog Spring Reverb
• Feedback Loop Pedal

Things I want to build...

• More LED-based pedals in candles: optical phaser, chorus
• Octave fuzz, octave up/down
• More stuff with transformers
• Something with the spare humbucker I have
• Something with the piezo pickup I made
• Enclosure for diode wheel
• Something with my music box
• That tremolo I have breadboarded
• Arduino DSP
• Guitar pedal patch bay
• Things with sliders (mixer?)
• Dial for delay pedal to fine adjust tempo
