Retrotechtacular: How Not to Design With Transistors

Consider the plight of a mid-career or even freshly minted electrical engineer in 1960. He or she was perched precariously between two worlds – the proven, practical, and well-supported world of vacuum tube electronics, and the exciting, new but as yet unproven world of the transistor. The solid-state devices had …read more

The Thrill of Building Space Hardware to Exceptionally High Standards

It’s fair to say that the majority of Hackaday readers have not built any hardware that’s slipped the surly bonds of Earth and ventured out into space proper. Sure we might see the occasional high altitude balloon go up under the control of some particularly enterprising hackers, but that’s still a far cry from a window seat on the International Space Station. Granted the rapid commercialization of space has certainly added to that exclusive group of space engineers over the last decade or so, but something tells us it’s still going to be quite some time before we’re running space-themed …read more

Ask Hackaday: Help Me Pick A CAD Package

Of all the skills that I have picked up over the years as an engineer, there is one that has stayed with me and been a constant over the last three decades. It has helped me work on electronic projects, on furniture, on car parts, robots, and even garments, and it is likely that I will continue using it periodically for the rest of my career. You see, I am a trained PAD expert.

PAD, you ask? OK, it’s an acronym of my own coinage, it stands for Pencil Aided Design, and it refers to the first-year undergraduate course I …read more

Young Entrepreneurs Learn What Really Goes Into Making a Product

Just to be clear, the primary goal of the Papas Inventeurs (Inventor Dads) was to have the kids make something, have fun, and learn. In that light, they enjoyed a huge success. Four children designed, made, and sold laser-cut napkin rings from a booth at the Ottawa Maker Faire as a fun learning process (English translation, original link in French.) [pepelepoisson] documented the entire thing from beginning to end with plenty of photos. Things started at proof of concept, then design brainstorming, prototyping, manufacture, booth design, and finally sales. While adults were involved, every step was done by the kids …read more

Bradley Gawthrop Loves Wiring and so Should You

Wiring is one of those things that we’ve all had to do on a project, but probably didn’t give a lot of thought to. It’s often the last thing that happens during the build, and almost certainly doesn’t get approached with any kind of foresight. You look at the components you need to connect, dig through the parts bins until you find something that looks like it should fit, and tack it in with a blob of solder and perhaps some hot glue if you’re feeling really fancy. We’re all guilty of it from time to time, but Bradley Gawthrop …read more

Modular Violin Takes A Bow

They say the only difference between a violin and a fiddle is the way you play it. If that’s so, this modular violin will need a new name, since it can be broken apart and changed in ways that make it sound completely different, all within a few minutes.

The fiddle is the work of [David Perry] and has 3D printed body, neck, pegbox, and bridge. While it might seem useful on the surface as a way to get less expensive instruments out in the world where virtually anyone has access to them, the real interesting qualities are shown when …read more
