Git Un-Merge

When I last merged a development branch of add-rel-lightbox into the master branch and realised that I’d not finished testing the changes, it was off to the internet to find out how to undo a merge. After a couple of goes at git revert -m 1 refused to do anything, and a little more searching, [...]

Dotsies on your Reader

Dotsies is probably the Dvorak of fonts — in a good way, of course. It’s better because it’s more compact; but they are both difficult to learn, very few people can use them well, and there’s no incentive to start learning them other than “they are better”. Though Dotsies is part of The New Aesthetic, [...]

Kingsbury K-Drive

The video below of the Human Power Team‘s elliptical drive system is the first time I’ve seen a non-circular power system in motion. Functionally identical to the “K-Drive” of the Kingsbury Kingcycle, the mechanism is first described in 1890, so it might be more correct to call it a “Vietor Elliptical Drive”, it’s best known [...]

Print your own John Carter

I’ve been coming across quite a few references to Edgar Rice Burroughs’ book “A Princess of Mars” over the past couple of months, from being the story behind Disney’s upcoming film “John Carter of Mars”, to being a classic science fiction text that has inspired many creators. So when it appeared again, as I was [...]

Putting Dotfiles in Git

If you’re a Windows user, then you probably won’t have come across dotfiles before. For Mac (a form of Unix) and Linux users, dotfiles hold certain environmental settings and customisations, so if you work on more than one computer, you might like a way of sharing your preferences between them. And they’re called “dotfiles” because [...]

European Velomobile Tour 2013

Bigest problem facing the expansion of the velomobile market is obscurity. There are plenty of people who could see the practical advantages of using a velomobile, and would interested in owning one, but for the low number of velomobiles around the world meaning that very few people have ever heard of them, never mind about [...]

LaTeX-SVG-to-PDF now compatible with LaTeX Project Structure Guidelines

I’ve pushed a couple up updates to LaTeX-SVG-to-PDF that come from some changes I made to my largest LaTeX project file. Since I converted a long (>100 pages) document from Microsoft Word format to LaTeX, I’ve now split the file down into the separate chapters for easier editing that are all \include{}‘d or \input{}‘d from [...]

Best Size for a Capacitor Bank of an Electric Vehicle?

A bit of a look into the future for the first post of this year. I don’t have any immediate plans to do anything electric vehicle, but the Atomic Duck could make a good lightweight EV platform, so I’ve been thinking about how the bits might fit in; specifically: What is the best size for [...]

Lattice Hinge Test Results

Sine last week’s post about modelling Lattice Hinges, I’ve received the test pieces I ordered and also some very kindly cut by .:oomlout:. (the MDF set gave me some good incite into the hinge performance). I’ve had time to bend some, break some (and figure out why) and take some pictures. Probably worth a look [...]

Laser-cut Lattice Living Hinges

AKA: Snijlab-style living hinges, Sninges, Laser cut hinges, or my prefered title: Lattice Hinges After this style of hinge popped up again, this time on Makezine, I was having a look at the linked project guide and at how they worked and I realised that a bit of mathematical modelling could lead to better designed [...]
