Service List

Current Services

SVC-01Scoped quote

Low-voltage board diagnostics + repair

Bench-level fault isolation and component repair for low-voltage electronics with a clear symptom, safe access, and a defined scope.

Useful for

  • repeatable board faults
  • power-supply and signal-path problems
  • repairable electronic assemblies

Includes

  • intake and fit check
  • visual and electrical inspection
  • fault-isolation record
  • repair and measurement summary

Boundary: No live mains, hazardous energy, safety-critical equipment, guaranteed recovery, or work without the legal right to service the device.

SVC-02Scoped quote

PCB assembly + rework

Prototype assembly, component replacement, and documented board modifications performed from client-supplied files and change instructions.

Useful for

  • prototype boards
  • small rework batches
  • through-hole and surface-mount assemblies

Includes

  • scope and material review
  • assembly or rework
  • visual inspection
  • completion record

Boundary: Work follows client-supplied assembly data and approved changes. It does not include original circuit design, redesign, or production-release approval.

SVC-03Scoped quote

Functional hardware testing

Execution of client-supplied test procedures and requirements with organized measurements, observations, and repeatable result records.

Useful for

  • prototype verification runs
  • repeatability checks
  • documented fault reproduction

Includes

  • procedure and equipment review
  • test execution
  • measurement log
  • results and exception report

Boundary: Testing is performed against client-supplied requirements. It is not compliance certification, independent engineering validation, or product approval.

SVC-04Scoped quote

Technical documentation

Clear evidence records for electronics work: what was received, what was observed, what was measured, and what changed.

Useful for

  • repair records
  • test-result organization
  • prototype build documentation

Includes

  • measurement tables
  • fault or exception notes
  • photo documentation
  • formatted delivery record

Boundary: Documentation records the performed work and supplied criteria. It is not a compliance dossier, certification, or licensed technical approval.

SVC-05Custom scope

Technical content partnership

Clear, evidence-led demonstrations and educational content for electronics tools, components, EDA, fabrication, and technical-learning brands.

Useful for

  • product demonstrations
  • sponsored explainers
  • technical UGC
  • event or workshop collaboration

Includes

  • scope and claim review
  • concept and script
  • technical demonstration
  • final deliverable package

Boundary: Sponsor access never guarantees a positive conclusion. Paid relationships are disclosed and claims remain evidence-led.

Safety + professional boundary

Service Boundaries

These are practical electronics services within my demonstrated experience. They are not licensed engineering, compliance certification, or safety-critical work. Educational content remains available free through my videos and bench notes.

  • Engineering consulting, professional-engineer services, stamps, or licensed design certification
  • Original client circuit or PCB design, formal design review, or production-release approval
  • Medical, life-safety, aerospace, automotive-safety, or other regulated-system work
  • Mains, high-energy battery, high-voltage, or hazardous live-work instruction
  • Compliance certification, independent product validation, or guaranteed fault resolution
  • Work that conflicts with employer confidentiality, ownership, or customer restrictions
