Diagnose before replacing.
I would rather understand why something failed than fire the parts cannon and hope.
ABOUT THE BENCH // SETH ESQUIEU
I’ve been taking things apart for a long time.
I’m Seth, an electronics engineer in Woodstown, New Jersey. For more than fifteen years, I’ve designed, tested, repaired, and occasionally argued with electronics for a living.
Grinning Frog Electronics is where I bring that experience directly to people and businesses with hardware that needs more investigation than the usual repair counter can give it.
THE USEFUL PART
A real engineer.
A very small shop.
My professional background spans embedded systems, industrial electronics, PCB design, board-level troubleshooting, firmware, RF power systems, controls, test equipment, and the fixtures and rigs needed to prove any of it actually works.
I’ve worked from both ends of the problem: designing new hardware from a blank page and tracing failures through equipment that has already lived a hard life. That combination matters. A good repair needs an understanding of how the thing was meant to work; a good design needs an understanding of how things fail.
This is an independent bench, not a volume repair shop. You talk directly to the person doing the work, and unusual projects are welcome.
HOW I WORK
Practical first.
Thorough where it counts.
“The goal isn’t to make the bench look busy. It’s to understand the problem and leave you with something that works.”
Bench-perfect isn’t enough.
Repairs and custom hardware should survive the environment they are going back into.
Not every repair is worth doing.
If replacement, a different approach, or stopping before the bill climbs is the sensible answer, I’ll tell you.

Send me the story, a few photos, and what you need the thing to do. Context always helps.
