I have about 1000 circuits in a binder I started in 1982, most of them culled from magazines and books and most of them hand-drawn! The early circuits below were drawn using Protel Schematic and are just a sampling of what's available and what I've done. (I've built hundreds of circuits.)
In 2010, I scrapped most ideas using integrated circuits like CMOS, TTL and 555 timers and graduated to Microchip PIC MCUs (micro-controller unit) for new projects. Easier to write software than doing it in hardware. I've also started using Arduino products because they are so plentiful with tons of software available.
