<p>Electrical engineer - industrial automation.
Long term hobby interest in electronics, audio and digital.
In decreasing proficiency: Bass guitar, guitar, piano, drums.</p>

<p>Website: <a href="http://LEDnique.com" rel="nofollow noreferrer">http://LEDnique.com</a> - practical electronic circuits and theory for LEDs and power. I found that I was answering rather a lot of question on EE.SE regarding LEDs and it seemed at times that a singnificant percentage of the Earth's population is trying to wire up, program, understand or destroy LEDs. Some answers required graphics that I couldn't find on the web so I created my own and wrote some articles.</p>

<p>Feel free to use the LEDnique graphics in your questions and answers. I'd appreciate a "source" link, of course.</p>
