DONETEK AS — Electronics Consultancy Stavanger

How we work with you

Choose the level of
involvement that fits.

Every engagement is different. Some clients need a senior pair of eyes on a design. Others need someone to run the engineering function entirely. We work with what the situation actually is. All engagements are led personally — by the engineer you’ll be working with.

01

Fastest entry point

Technical Review

External eyes on your engineering.

Design reviews, architecture audits, technical due diligence, independent assessment. We join your process as an external senior voice — clear findings and actionable recommendations, no long-term commitment required.

Good for

Investor or board due diligence · Certification preparation · Recurring design review support · A second opinion before a major technical decision

Hands-On Development

We do the actual engineering work.

Electronics design, PCB layout, embedded firmware, software development, test bench design, prototype assembly. Defined scope, delivered. Hardware, firmware, software, or the full stack — including high-temperature systems, high-voltage design, and continuation of existing or legacy designs.

Good for

Specific development tasks · Filling a capability gap · Short-term embedded support · Augmenting an existing team

03

Product Ownership

We own a product end to end.

Responsible for the outcome, not just the deliverable.

System architecture, human-centered design, engagement with users, sales teams, and management, specification writing, production readiness, cost optimisation. We carry responsibility for the outcome and structure everything so it can be handed cleanly to whoever comes next.

Good for

Prototype to production · Complex multi-stakeholder programmes · De-risking before scale

04

Department Leadership

We run your engineering function.

Technical strategy, team, delivery.

Full ownership of the electronics department — technical strategy, hiring, mentoring, budget management, delivery planning, and all engineering decisions. Senior technical leadership without the overhead of a permanent hire.

Good for

Growing fast and the engineering function hasn’t kept up · Going through an acquisition and need technical continuity · Lost your CTO or technical lead and need cover while you hire · Need senior technical direction without committing to a full-time salary

Technical Recovery

We step in when continuity has broken down.

Assess. Stabilise. Restore momentum.

When key people have left, technology has drifted past what the team can clearly describe, or commitments to clients, investors, or the board are at risk — we assess the situation and do what is necessary to restore confidence and momentum.

Post-departure stabilisation · Stalled programmes · Technical clarity before a board presentation or funding round

Selected work

Oil & Gas — Downhole Tools

From post-acquisition uncertainty to a stable, production-ready electronics department.

Took full ownership of the electronics and software function at a downhole intervention company following an acquisition. Drove an architecture redesign that eliminated recurring field failures, scaled tool inventory across three production families, and built an engineering team from the ground up.

Oil & Gas — First-of-Kind Technology

The world’s first practical downhole X-ray system — from development to first successful image.

Electronics design on the VisuRay VR90 — high-voltage circuitry, PCB design, firmware, test bench design, and clean room assembly. The VR90 attracted joint development funding from ConocoPhillips and Statoil and became the foundation for the next-generation VR360 platform.

Marine Geophysics

A distributed seabed platform brought to field deployment.

Joined PetroMarker AS during a critical re-architecture phase. Took ownership of electronics design, system integration, and deployment preparation for a distributed autonomous seabed node platform combining ultra-low-noise sensing, active levelling, precise time synchronisation, and controlled recovery.

Oil & Gas — Safety-Critical

Full electronics architecture for a P&A system — first funding to live well.

Sole electronics architect for a plug-and-abandonment startup from initial investment to successful live well testing. Extended Highly Accelerated Life Testing without failures. No in-field intervention possible — everything had to work the first time.

Oil & Gas — Harsh Environment

Downhole intervention electronics at up to 170°C.

Designed a suite of intervention electronics at the thermal limit of standard component ratings: dual-core 32-bit control board, battery-powered autonomous timer for multi-year deployment, and a digitally controlled DC/DC converter with all regulation in firmware.

Electric Vehicles

From prototype to a product featured in Norway’s leading business newspaper.

Designed core electronics for the Podbike Frikar enclosed electric velomobile — vehicle control unit, lighting controller, and multi-transport OTA firmware update architecture. Featured in Dagens Næringsliv.

Technical scope

Hardware Architecture

PCB and schematic design for safety-critical and harsh-environment applications. High-temperature operation to 170°C. High-voltage systems up to several hundred kilovolts. Power electronics, battery management systems (BMS), and precision sensor interfacing.

Embedded Firmware

Embedded C, C++, and ASM on ARM Cortex, nRF52, MSP430, AVR, PIC, and 8051 platforms. Real-time systems. CAN, CAN-TP, LIN, UART, RS485, Ethernet, BLE, USB. OTA bootloaders built for long-term field maintainability.

Software & HMI

Embedded Linux, Qt, Android, Python, C#, and desktop applications including Delphi and Borland C++ Builder. Touchscreen HMI and field service tools. Data logging for platforms where missing records carry regulatory or operational consequences.

Systems & Validation

Architecture design and independent review. Technical documentation built to survive team changes — so the next engineer isn’t starting from scratch. Extended stress testing under accelerated conditions (HALT). CE certification and EMI/EMC compliance testing managed through specialist partners.

Production & Delivery

Design for manufacture, supply chain management, contract manufacturer coordination, PCB assembly oversight. Technical ownership from first schematic to volume production.

Operating Environments

Oil & Gas downhole tools · Seabed survey systems · Medical devices · Electric vehicles · Industrial safety-critical platforms. The common thread: if it fails in the field, you can’t just send someone to fix it.

Track record

Every project in the work section above was delivered.

The person behind every engagement

Vaidas Zakarka

Founder & Principal Electronics Consultant

Vaidas Zakarka has been designing electronics for over 20 years. The last decade has been focused on environments that don’t forgive mistakes: downhole tools operating at up to 170°C with no maintenance access, high-voltage systems reaching several hundred kilovolts, and distributed platforms where a single undetected fault can end a programme.

He has worked across Oil & Gas, marine geophysics, medical devices, and electric vehicles. In most of those engagements — and in every DONETEK engagement — he has been the person accountable for the outcome, not just a contributor to it.

You deal directly with the person doing the work.

“I’ve been handed systems where nobody could tell me what half the board did. I’ve taken over from engineers who left without documentation, from projects where the original architect was three companies ago. That’s not unusual. What’s unusual is being willing to deal with it.”

Get in touch

Let’s talk about your project.

Whether you’re starting a new programme, scaling an existing one, or in a situation that needs a clear technical owner — a direct conversation usually moves things faster than weeks of internal deliberation. No obligation. A short call — you talk directly to Vaidas, not a sales layer.

Starting a new electronics development programme?
Scaling from prototype to production?
Need senior technical leadership without a full-time hire?
Looking for independent design review or technical due diligence?
Key technical staff have left and continuity is at risk?
Facing a certification deadline or investor review?
