Services
Focused design work with clear scopes, fixed-price quotes and complete hand-over files.
PCB design
Schematics, 2–6 layer layout, BOM, Gerbers and assembly files. DipTrace, KiCad and other major EDA tools.
Power electronics
DC-DC and AC-DC converters, gate drives, magnetics, resonant and high-frequency designs.
Custom power supplies
Compact high-frequency supplies from 10 W to 3 kW, including high-voltage outputs up to 50 kV, built to your specification.
Simulation and analysis
Circuit simulation, loss and thermal estimates, design review of existing schematics.
Proof-of-concept prototypes and small runs
Help with proof-of-concept prototypes and design-to-manufacturing support: component sourcing, assembly, testing and shipping of prototypes and small production batches.
Repair and debugging
Bring-up, fault finding and repair of electronic equipment, with a written test report.

Prices are for general information only and are not an offer. Every job is quoted individually as a fixed price, confirmed in writing before work starts. Design work is invoiced on delivery; hardware builds are paid 50% on approval and 50% on delivery; materials are paid in advance. Prices exclude GST/HST.
Monthly support packages (USD)
Research, consulting, schematic review, simulation and reports.
| Package | Hours per period | Unused hours | Extra hours |
|---|---|---|---|
| $600 | 11 h | expire | $60/h |
| $1,200 | 24 h | expire | $60/h |
| $1,800 | 40 h | carry over one period | $45/h |
| $2,400 | 60 h | carry over one period | $40/h |
- Prepaid; each period runs 30 days from payment. Renews when the next period is paid — no long-term commitment, cancel anytime by not renewing.
- Carried-over hours are used first in the next paid period and expire if the package is not renewed.
- Extra hours are prepaid and subject to availability.
- Design work — schematics, PCB layout and prototypes — is quoted separately as a fixed-price project.
- Prices exclude GST/HST.
How we work
A simple, predictable process: you know the price before work starts.
- Brief and quoteYou describe the goal. Usually within 2 business days you receive a written fixed-price quote with scope and timeline.
- ApprovalReply “Approved” by email and work starts. Larger projects get a short statement of work with milestones.
- Design, build and testSchematic and simulation first, then layout. Prototypes are built and tested against the agreed requirements.
- Hand-over and paymentYou receive complete source files, documentation and a test summary, with an invoice payable on delivery.
