Electronics Debug & Lab Support When Your Team Is Stuck

Q: Do you take small or rush jobs?

Yes — most small projects are completed in 1–3 business days. We’ll confirm scope and timeline up front and include clear pass/fail results with inspection photos.

Q: Can we ship parts in, or is this local only?

Either works. We handle ship-in or local drop-off. For ship-ins, we’ll share packing guidance and include photos in the final report.

Verified. Qualified. Simplified.

Hands-on support for bring-up, troubleshooting, validation, and rework — so your team can move forward without adding headcount.

Common Problems I Help Solve

Board powers up but won’t boot
Random resets or unstable behavior
Works on the bench but fails under load
Intermittent issues that are hard to reproduce
I2C / SPI / UART communication problems
New prototypes that need safe bring-up
Boards that need repeatable testing across units
Noise or interference causing weird behavior

Capabilities

Practical, hands-on lab support across bring-up, troubleshooting, validation, and rework. Whether you're working through a new prototype, tracking down an issue, or building a repeatable test setup, the focus is always the same — clear answers and a path forward.

PCB Testing & Validation
PCB Bring-Up & Test
Custom Cable Assemblies

Electrical Troubleshooting

Signal Capture & System Behavior Analysis

Simple system, but the same approach I use when troubleshooting real hardware — capture the signals, correlate behavior, and understand what the system is actually doing.

Captured hall sensor trigger and correlated full system response
Measured end-to-end response delay (~976 ms) between input and output
Identified transient behavior during speaker activation
Captured and analyzed SPI communication to TFT display
Verified timing and integrity of SCK, MOSI, CS, and DC signals (~400 µs transaction)

Oscilloscope capture showing hall sensor input and speaker output timing

Hall sensor input vs speaker output — measured system response delay ≈ 976 ms

SPI communication capture showing SCK, MOSI, CS, and DC signals

SPI display communication — SCK (clock), MOSI (data), CS (chip select), and DC (command/data) during display update (~400 µs)

This is the same approach I use to diagnose real system issues — isolate signals, verify behavior, and remove guesswork.
