Welcome to my collection of electronic schematics and experiments.
I’m not a professional engineer or electronics designer - just an enthusiast who enjoys exploring circuits, learning how things work, and experimenting with ideas. Over time I’ve collected and modified a variety of schematics that I found interesting, useful, or simply fun to build and test.
This site is a place to share those experiments with other curious minds who enjoy electronics, DIY projects, and hands-on discovery. Some circuits may be original variations, others are inspired by existing designs, and many are works in progress. They are shared here in the spirit of learning, collaboration, and experimentation.
If you’re an experienced engineer, a hobbyist, a student, or simply someone interested in electronics, I hope you find something here that sparks ideas or encourages you to build and explore further.
Please remember that these schematics are experimental and should be used responsibly and safely.
If you feel inclined, you can also send me a small donation via Paypal - even as little as $2 AU is appreciated.
Enjoy exploring!
Safety Disclaimer! Some projects featured here involve elevated DC voltages and mains-powered circuits. These voltages can cause serious injury, electric shock, or death if handled incorrectly. Proper safety precautions should always be observed when building, testing, or modifying electronic equipment.
If you are inexperienced with mains wiring, high-voltage electronics, or electrical safety procedures, do not attempt to work on these projects. Always use appropriate isolation, protection equipment, and safe working practices.
Please note: This is a work in progress, and stuff is added/updated in my down-time from working and when I don't have any video content to make. It also takes time to draw schematics and/or simulate circuits I haven't built yet. Any projects presented that have been simulated but not built and tested will be marked as so.
