Cupcake Half Aria

Posted on January 10, 2015 by paulwallich

Everyone seems to be printing Aria these days, and it has a high rating for printability, so I figured on putting it to the acid test: my old cupcake.  Darned if it didn’t work OK. I had to scale it … Continue reading →

Posted on January 8, 2015 by paulwallich

For christmas, my delightful spouse got me an Eggbot kit. And since one of the resolutions this new year is to build kits instead of just getting them, putting them on a shelf in the basement and dreaming about how … Continue reading →

Posted on December 29, 2014 by paulwallich

I think the workbench was one of the first things I built in the basement after we moved in 14 years ago, out of leftover flooring from the previous place. It’s long since become just one more flat surface punctuated … Continue reading →

Like kids in a candy store

This morning I had a short meeting with the Cardboard Teck Instantute (aka Ben Matchstick and Pete Talbot), who have a residency at Generator next month.  These guys are so good at building toys, games, vehicles, whatever entirely out of … Continue reading →

The encrustation of the analog on the digital

Posted on December 8, 2014 by paulwallich

I am amazed that this works

Posted on December 1, 2014 by paulwallich

I knew those clip-on magnifiers were good for something other than soldering. That’s an 0603 surface mount LED, held down by wire glue. The traces are silver conductive ink, and those huge-looking red and black conductors are 22-gauge hookup wire. … Continue reading →

A dumb but nice thing I did

Posted on November 22, 2014 by paulwallich

Here’s what I like about having a 3D printer in the basement. Tonight the 9-year-old had a friend over, and we all got some pizza, and on the pizza were a couple of those little legged-spacer things that keep the … Continue reading →

An unintended consequence of wire glue’s high resistance

Posted on November 16, 2014 by paulwallich

With all deliberate speed

Posted on November 14, 2014 by paulwallich
