About SDG Electronics

Hi, I'm Steve Gardner.

I am an electronics engineer and technical project lead with more than 20 years’ experience in medical electronics design.

My professional work involves developing complex electronic systems in a field where quality, precision and reliability are essential. My role combines detailed engineering with technical project leadership, taking demanding developments from initial requirements and investigation through design, verification and delivery. Much of this work is highly specialised and innovative, requiring careful analysis, sound engineering judgement and close attention to detail.

I also enjoy producing videos about the many aspects of electronics engineering that particularly interest me. These include detailed electronic design and practical assembly techniques, from circuit design, PCB layout and component selection through to soldering, rework, inspection and fault-finding. I also cover firmware, embedded systems, test and measurement, audio electronics, reverse engineering and component-level repair.

Another important part of the channel is impartial equipment reviews. I carry out detailed testing and practical evaluation to examine how products perform beyond their published specifications. By looking closely at construction, performance, strengths and limitations, I aim to give viewers the technical information they need to make informed purchasing decisions.

My videos are intended to be detailed and technically useful. I explain the reasoning behind a design or investigation, demonstrate the techniques involved and present the measurements and evidence that support my conclusions.
