Out For a Bit
Hey. I’ve been absent for a bit, and I’m unfortunately going to be absent for a little bit longer as I sort out some things with my health. My posting schedule may be a bit erratic for a few weeks and my email replies will be delayed. Thank you for...

No Post This Week
Howdy. There will be no post this week. To be honest, I injured myself in a very dumb and minor way. I’ll be totally alright but it’s made typing quite a chore for me in the meanwhile. I’ll get back to you next week with some project updates. Until then,...

I Got 99 Problems and They're All in Fahrenheit
I’d meant to post a final update on my garage workshop project soon, but honestly, it’s become too damn hot in beautiful Merced, California. I’m lucky that I work a hybrid schedule so I don’t need to venture out into the otherworldly heat every day, but the heat nonetheless still...

Starting a Homelab
Howdy! The past few days have been a bit rough for me so today’s post is going to be pretty short. A couple of weeks ago, I mentioned that I’d be starting a homelab. Over the past week or so, I’ve been doing a lot of planning and material gathering...

Manual LoRa Demodulation Given Limited Information
Demodulating LoRa manually is a non-trivial task that requires a deep and fundamental understanding of RF and LoRa. Although there exist plenty of tools on the Internet today that can easily and automatically demodulate LoRa given I/Q data and the right arguments, having limited information to inform the latter leaves...

Summer Projects
I’m not a student anymore so I don’t really get summer vacations, but I work in higher ed so I at least know when summer vacation starts and ends – well, that and I live in the Central Valley, so it usually starts when it begins to get unbearably hot...

New Beginnings
Hey. It’s been a while. I was working on some projects for the past few months and then I was honestly just burnt out for a while. I had originally meant to post this a month or so ago, but I’ve just been lacking energy lately. Perhaps it’s the change...

Mediocrity in a Post-College Life
Hey there. It’s been a while since I’ve talked about what’s been going on in my life. Not my projects or events or whatever, but me: Shawn D. Maybe that’s because I’ve become more closed off these past few months. Maybe that’s because, frankly, not much of interest has happened...

Gratitude
It’s Thanksgiving. I’m back in SoCal visiting my family and enjoying some time off from work, which frankly has been draining lately. I haven’t much to talk about today besides thanks to give: thanks to my family, friends, and teammates, to my teachers and mentors and everyone who’s helped me...
