I’ve been having trouble gluing PLA parts together reliably., so I decided to do a brief experiment.
How to Estimate Your Remaining Filament
“Do I have enough filament to print this one thing?” That’s the question on my mind whenever I’m nearing the end of a reel of filament. I can’t stand wasting a few meters of filament by underestimating what’s left, and I don’t want to unwind a few meters of filament just to measure it and wind it back on the reel.
How to write an Arduino Library that contains Sketch-conditional code
Recently while working on an open source Arduino library (more about that later) I ran into a challenge: how to make the library’s interrupt-related code compile into the Sketch only if the Sketch writer needed it?

The best way to store 3d printing filament
If you’ve done much 3d printing, you’ve probably noticed occasional bubbles in your print. Many 3d filaments absorb water from the air, causing the plastic to bubble as it extrudes from the hot end of the printer.
What is a Brim and why does my 3d print need one?
I’ve been designing 3d printed parts for a while now, and thought I had the process down to a science. Continue reading What is a Brim and why does my 3d print need one?
I’ve integrated JavaCC with Android Studio
A calculator Android app I’m writing needed an expression parser, so I researched how to build one. I started by reading a bit of Google’s Android Open Source Project Calculator source to get some ideas.
We’re celebrating Site Founding Day today, the day after Oregon’s birthday. Welcome!
Does Superglue work with 3D Prints?
Having read Clifford Smyth’s excellent book, Functional Design for 3D Printing, I was anxious to try out his method of cutting a design into parts and gluing those parts together after printing.Continue reading Does Superglue work with 3D Prints?
The Co-Presidents in Britain
In the fall of 2000, the co-presidents spent a month in Wales and England. For Linda it was a research trip into English king Edward’s medieval castles (built to crush the Welsh), and into various Victorian museums covering everything from candy to coal. For Brad, it was time to be a tourist: once every seven years at Intel, you get a block of 8 weeks off to reacquaint yourself with the world, so Brad spent half of his 8 weeks on tour.
Here’s a very brief look at the places we visited, culled from our 2,400 photos made possible by Brad’s then-fancy digital camera and Linda’s laptop. Each night, Brad would download the hundred-or-so photos from the camera to the laptop, freeing the camera to take another couple hundred photos the next day. We have research photos of portcullis slots, murder holes, stairways, hallways, garderobes, merlons, embrasures, and many other details of the castles and houses we visited.
For some reason we really like mines. In our various tours we’ve been inside salt, slate, copper, and coal mines.
In 2000 the prehistoric Great Orme copper mine was just being opened to tourists. It was spectacular even then, and now (2021) even more of it has been excavated.
We also like “Have a Go” stuff, such as this dress-up at the Dewa Roman Experience in Chester.
Hay on Wye is an entire village of bookstores, and of course heaven for an author. I seem to recall on that trip we brought back two duffle bags full of books.
In Chester we compared Romanesque arches to Gothic arches… and McDonald’s arches.
The Co-Presidents Reuinite in Fiddler On the Roof
In June and July 2000, the Co-Presidents were reunited on stage for the first time in 18 years (too long!): Linda played Golde, Tevye’s wife, and Brad played Lazar Wolf, the butcher, in Stage One’s production of Fiddler on the Roof. Stage One is a fundraising organization for the Hillsboro area high schools’ performing arts departments.
It was great to be on stage with my honey again!
