Chandler Swift


I’m a lifelong hacker (the good kind!). My parents have a story they like to tell at my expense: At just a few years old, I was interested enough in my Dad’s laptop brought home from work one evening to somehow manage to change the operating system language into German. Of course, I vehemently deny everything. The interest in computers has stayed, though I like to think I require a bit less supervision now, and I like to tinker with hardware and software everything in between. Things I like include C and Go and Linux and Assembly and MIDI and abusing hardware and…! Things I don’t like include: CSS. I run this software on this OS on this hardware. Ask me about my latest project!

As a musician I’m wrapping up a stint as the organist/pianist/accompanist at Pilgrim Congregational Church in Duluth, MN, and another as an accompanist for the Lake Superior Youth Chorus. When I’m in Duluth, I often play for Jazz at Blush on Monday nights (and if you play an instrument, please come join us!). I especially enjoy playing in small ensembles and with other people as much as I can.

In my free time, I try to remain active with my Boy Scout troop (of which I am an Eagle Scout), especially on outdoor activities. I enjoy reading science fiction, though I don’t have as much time for it as I might like. I appreciate XKCD comics, especially about technology.


Jan 2023 Advent of Code 2022: Days 20 and 21

Two more down, today. Magit has been awesome, and I think I made it through the entirety of both of these problems without reflexively opening a terminal to solve some problem I encountered (either regarding git, or basic file manipulation)!

Jan 2023 Advent of Code 2022: Days 18 and 19

I’ve been recovering from a rough bout of COVID-19, which really knocked me out for a few days, and (in combination with a tough couple problems) set my AoC progress back a few more days. But I’m back at it! Today: getting acquainted with magit.

Jan 2023 New Year, New Router!

Over Christmas break, I replaced my old router (a standard x86_64 PC running pfSense1) with a new FriendlyElec NanoPi R2S, which has (for the first few days, anyway) been a fantastic bit of hardware. On the software side, I’m running OpenWRT, which is a stability upgrade from pfSense, and a major functionality bump from any other router OS I’ve tried. I’m now a few days in, and it’s been a really nice experience.

Jan 2023 Advent of Code 2022: Days 16 and 17

Well, it’s slow going. I was getting less than a day per day done, and now I’m back at work, so that’ll likely be even slower going forward. I’m retargeting mid-January for the end. But here are the next couple days’ worth!

Dec 2022 Advent of Code 2022: Days 12–15

Well, Advent is long over, but here I am! I was traveling and visiting family, which was delightful but really set back my AoC progress. But I’m hoping I’ll be caught up by the new year! New this time: eww, the Emacs Web Wowser.


Dec 2022 Advent of Code 2022

This is it: I’m finally going to finish Advent of Code this year! (A strong claim, given that this is my third attempt, but we’ll see!) This year, I’m planning to use this as an excuse to learn/relearn Emacs and Rust.

Jan 2021 Van Conversion Electronics

In which I help my brother to add an electrical system to his van conversion project, including lighting, battery control, automatic charging and disconnect from the vehicle battery, and a 120V inverter.

Dec 2019 Tracking Duluth buses with an interactive light-up map

In which I design and build a 3x4 foot interactive map of Duluth (or at least the parts in which I regularly travel) to view bus locations

Nov 2018 Auto-timed Fish Tank Light

In which I build a NTP-syncin’ LED-blinkin’ fish light timer.

Mar 2018 Using a 5.25" Floppy as a MIDI instrument

In which Jeff and I get hopelessly distracted from our original goal and wind up making music from a 5.25" floppy drive.

Dec 2017 Building a MIDI Pedalboard

In which I build a MIDI pedalboard from a Baldwin 125B pedalboard and a bit of Arduino magic!

Jul 2017 ESP8266 Light Switch: A Few Revisions

In which I attempt to explain the many revisions of my ESP8266 light switch, as well as some of the cooler ways to control it.
