About Me
Hey, I’m Francisco. I bring vintage electronics back to life and engineer solutions that last.
I'm pursuing a B.S. in Electrical and Computer Engineering Technology at Valencia College, focusing on restoring and reverse-engineering precision test equipment, vintage audio gear, and other difficult-to-service devices. I enjoy solving problems others consider impossible, especially with equipment that has outlived its expected service life.
I run Open Source Electro, where I restore vintage cassette decks, from basic transports to rare collectible models. Each repair is documented in detail with notes, schematics, and custom-designed replacement parts, all shared online for fellow enthusiasts.
Previously, as an Electro Mechanical Apprentice at Stewart’s Electric Motor Works, I disassembled, inspected, and rebuilt electric motors, pumps, and generators. I gained extensive hands-on experience with industrial three-phase systems and motor controls, operating specialized diagnostic equipment and providing clients with critical insights into failures and targeted recommendations.
I’ve also repaired and upgraded professional test instruments such as oscilloscopes, waveform generators, and spectrum analyzers. When standard parts aren't available, I design custom PCBs, source specialized components, and use 3D modeling and printing to create fixtures and replacements.
Outside of electronics, I’ve completed major automotive retrofits, including modernizing a 1973 Plymouth Duster with OEM parts, custom electrical systems, and an engine conversion, combining mechanical and electrical engineering.
At Valencia College, I work as a Lab Technician and Teaching Assistant, helping students connect theory with practice in circuits, digital logic, and microcontrollers. I also design in-house solutions to update lab equipment and improve student learning.
I’m always looking for the next project that challenges me across electronics, mechanics, and systems engineering.
