Ten Years Gone

Though it’s not the day that I want to most remember her by, I can’t let today go by without noting that it’s been ten years since Michelle passed . If you didn’t know her, or maybe even if you did, you can read her obituary or the eulogy that I gave at her funeral . Instead, I choose to remember her by her adventures, by her unbridled enthusiasm for life and fun…

Supercon 2025 Badge Hack

I greatly enjoyed Hackaday Supercon again this year after attending for the first time in 2023. Why did I miss last year? I don’t have a good reason, but it’s not happening again! One of my favorite parts, and probably of many attendees, is the badge hacking. This year’s badge ( announcement , GitHub , schematic ) was an extra bonus as I love small handheld computers . I spent a…

When Having a Computer Was Weird

I just finished up the first weekend of my vintage computer exhibit for Portland Design Month entitled When Having a Computer Was Weird: A showcase of early personal computers . I had two fun groups of visitors and I plan to run another date on October 18 , plus others as time permits and interest demands. I have eight vintage computers from my collection on display, working and ready for people…

Creating an electromagnet and sound wave learning environment

I’ve been meaning for a while to write more about one of my recent projects, Catch the Wave! . Originally it was made for last year’s Oregon Science Festival and since I’m exhibiting again at the festival this year ( this weekend , in fact!) I thought now was as good a time as any. What is it? Catch the Wave! is a public science education project, with the side goal of bettering…

fari: fast Safari tab browsing

I’ve been hacking on and off for a few years on a little open source side project, fari . It’s a terminal-based utility for the Mac for quickly zipping through the tabs that you’ve got open in Safari. Recently, I started picking it back up again as I have been meaning to apply some research into getting at Safari’s iCloud Tabs and even Tab Groups. iCloud Tabs are a way to…

Winter Walk

Took a ~4 mile walk in the newly-snowy neighborhood this afternoon. For the first time in years , I grabbed my camera to go along. I need to retrain my eye to look for photo opportunities. Feeling a little rusty so far. You can read a bit more about Futel and the payphone here .

How my link blog works

Despite not posting stuff as much as I’d like to get around to on this site, I do keep my link blog pretty active. It lets me share publicly some links to things on the web, sometimes with commentary. I run the Hugo content management system, but the generalities could apply to a lot of systems if this is something that you’d like to replicate. Here’s an overview of how I use it…

Repurposing Hugo as a wiki

As part of a project that I’m working on, I decided to see if I could repurpose the excellent Hugo website framework (which also powers this very site) as a single-user wiki of sorts. Short version: yes ! Requirements The main features that I wanted were: The ability to, while writing a page, freely link to other topic pages that I know will (or at least plan to make) exist in future ,…

Now page year-end 2023

I just updated my now page . I like it because it’s something I can do three or four times a year, pretty casually, and feel like I’m not so behind in talking about WTF I’m actually doing with my time. And it’s a nice way to reflect a bit and regroup.

The wave's been caught

I successfully finished and “shipped” my booth, Catch the Wave! , at the inaugural OMSI Oregon Science Festival this past weekend. I don’t have a good sense of how many people I interacted with over the course of the two days, but I would guess somewhere in the mid- to high-hundreds. There was very little downtime from 9:30-5:30 both days, and because my experiment stations were…
