About Me


hlio [at]

Currently an Embedded Systems Engineer in the Oceanography department at the University of Hawaii at Manoa. MS in Electrical Engineering from University of Southern California in 2015, BSc in Computer Engineering from York University (Canada) in 2013.

Born as Hou In Lio ("Lio" == last name) in Macao, but known as Stanley by everyone I know on this side of the Earth. Interested in all things engineering and most things science-y. Play a few Chopin nocturnes and Beethoven sonatas and am a "weekend photographer".

I'm interested in digital communications particularly with low-power embedded devices with limited hardware resources. Also do quite a bit of backend web dev and a little frontend web dev when there's real-time data to visualize.

"Why engineering?"

That, that, and thatThat’s why.

Motivation For These Hobby Projects

I spent a lot of time in school mastering the various theories and tricks, only to realize later that I couldn't actually use any of that in practice because the assumptions for these theories to work rarely apply in practice: most systems are non-linear; you don't actually get a closed-form solution for any of the differential equation tricks to work (not to mention nobody solves them by hand in real life); time series are most often not sampled at fixed interval (so FFT off textbook won't work).... Had I known that earlier I would have allocated my time and effort accordingly. Not to mention theories make no sense if I can't relate it to something practical I can experiment with. Made-up side projects seem to be a good solution.


Like many I began by building several clocks in order to practice soldering. The first one was the size of a large shoe box, built using dozens of 4000-series logic chips and a box full of wires. The last one was built using a microcontroller on a custom PCB. One of them went on to permanent display in my high school (along with a few robots I built), while another is still running on my wall seven years after it was built (though not without a little upgrade).

Embedded system development was something I picked up before there was such thing as "Instructable" or "Arduino". It was exciting to see how a box full of logic chips and wires can be replaced by a single chip + software.
