Welcome! I am an engineer, programmer, designer, and gentleman. You may be interested in some of my electrical and mechanical projects. Take everything you read here with a grain of salt and remember to wear your safety glasses.

SmartClik Scissor Design on the Market

I'm pleased to reveal some industrial design work I did at the end of 2016 for Washi Scissor, a manufacturer of high-end scissors for barbers and dog groomers. Washi's founder Marc Milman (introductions made by patent illustrator Denis Autridge of ASCADEX) asked for my help developing his idea. Scissors with swiveling thumb rings already existed, but the ability to lock the thumb ring at various angles, helpful to give users mechanical feedback while still accommodating differences in their hands and styles of working, is new.

Logo Design for South Florida Nom Squad

SoFlo Nom Squad

I designed this logo for the South Florida Nom Squad, a dining and culinary-adventure club led by my girlfriend Samantha Calabro. Cute cartoon animals aren't really my specialty but I'm reasonably pleased with how well this manatee turned out.

3D-Printed Impossible Dovetail Puzzle

Here's a 3D-printed version of the classic impossible dovetail puzzle, inspired by a machined metal version by Chris at Youtube channel Clickspring.

After modeling the geometry in Onshape, I printed my version in Estonian blue, black, and white. I wanted to sign my name on the pin so I rebuilt that part in Solidworks, which still offers a less annoying way of importing 2D vector art for this sort of feature. If you'd like to make your own impossible dovetail or play with the CAD models, follow these links:

A Filament Extender Guide for Crystal Palace

I recently documented my designs for a kind of filament extender structure that I added to my 3D printer to keep the filament a bit more under control on its way from spool to extruder. Maybe it will be of use to someone else that has a Prusa i3 clone like mine.

Reading List for 2018

Last year's reading list is complete. I'm pleased to report that I met my target number of 36 books for the year (although only just!). My usual practice in case of success last year would be to set a higher goal for this year, but it's occurred to me that chasing ever higher numbers has the effect of encouraging me to read shorter books, which isn't exactly in line with the spirit of this enterprise. So I'll keep it at 36 and still try to read more, by reading longer books.
