Products & technology
Engineering you can experience.
Our products put the hardware and software together. Discover what is available today and what we are developing next.
Available to order
picspeak
Personalised flat-panel speakers that bring artwork and sound into the same object. Choose your artwork and explore the current speaker system.
Distribution & strategic partnerships
We are exploring selected distribution and strategic partnerships to bring picspeak to new customers and markets.
In development
picstream
Local-network audio connecting applications and embedded devices, designed for synchronised multi-device playback and integration into products.
An open-source release is planned as the platform matures.
Android application
G-meter
10K+ downloads on Google Play
A publicly released Android application for visualising and recording acceleration using your device’s sensors.

Embedded systems & connectivity
picstream combines embedded audio endpoints, network communication and application software as one integrated system.

Application software
G-meter combines Android sensor acquisition, real-time data processing and measurement visualisation in a released application with 10K+ downloads.
Engineering partnerships
One product.
A connected engineering process.
Work with SiriusLab when the electronics, firmware and application need to work as one system. We take on selected development projects with a clear technical goal.
A good starting point is a defined discovery or feasibility phase: establish what needs to work, what is uncertain and what the next development stage should deliver.
01
Define the brief
Turn the concept into requirements and a system architecture. Establish feasibility, budget and the risks that matter.
02
Develop the system
Circuit and PCB design, embedded firmware, application software and mechanical integration.
03
Build and evaluate
Integrate the prototype, test the complete system and refine it for practical use and production preparation.
04
Plan the handover
Define the documentation, source-code delivery, IP arrangements and ongoing support needed for a clean handover. These expectations are agreed at the beginning of the project and maintained throughout development.
Have a product you are trying to build?
Tell us where the project is today and what you need to make it real.
Our approach
Build for the life of the product.
We favour clear design decisions, useful documentation and technology that people can understand. These principles guide development; each product’s documentation explains what is supported today.
Product autonomy
Design core functions to work without unnecessary dependence on cloud services, subscriptions or third-party infrastructure.
Longevity and repairability
Make products understandable, serviceable and maintainable where practical. Consider access, documentation and support alongside the first prototype.
Transparent technology
Document protocols, interfaces and system behaviour. Complexity should serve the product rather than obscure how it works.
Secure by design
Protect credentials, private keys and other sensitive information while keeping architecture and engineering principles understandable and inspectable.
About SiriusLab
Independent. Hands-on.
Product-focused.
SiriusLab Technologies Ltd is an independent UK engineering company based in the South West of England. We develop electronics, embedded systems and software for our own products and selected client projects.
Led by Marijan Cimerman, SiriusLab brings electronics and software development together around the complete product. Work directly with the person doing the engineering, from the technical brief through prototype integration and handover.

Mechanical enclosure design · picspeak amplifier housing, front-panel controls and display integration.

What are you building?
Tell us what the product needs to do, its current stage and, if known, your target date and budget range. We can then discuss whether SiriusLab is a good fit and define a sensible next step.
Product questions, picstream integration enquiries and engineering briefs are welcome.
