I’m Li-aung “Lewis” Yip, from Perth, WA, Australia.

I’m a power electrical engineer. That means that I measure voltage in kilovolts, power in megawatts, and my favourite numbers are √3 and i. My work involves:

  • Power system analysis. (I simulate things blowing up.)
  • Power systems protection. (Sensors that detect when things are blowing up.)
  • Designing, building, operating, upgrading, and maintaining electrical transmission and distribution assets. (Which hopefully won’t blow up.)

My three superpowers are: making computers do what I want, drawing really good diagrams, and beating Microsoft Office until it submits to my will.

My favourite feeling in the world is to teach - usually one-on-one, with scribbled sketches on scrap paper.

I geek out about science, engineering, and IT. I’d buy a lathe, mill and welding set right now, if only I had a place to put them.

I’m “internet famous” for things I’ve done in Minecraft, and my thesis on Online Empirical Mode Decomposition.

My website tries to be like Sam Hughes’, Manfred Mornhinweg’s, Russ Cox’s, and J. B. Calvert’s.

  • Plain. No distractions.
  • Full of things that are:
    • Written by me.
    • One or more of: useful, interesting, entertaining.
    • About science, technology, engineering, math.
    • Not listicles.
  • A good citizen of the internet. (Small page sizes. HTTPS.)
