About Bitcoins
As Bitcoins are a Maker currency — invented, open sourced and run and maintained by the invested network — I’ve been looking into accepting Bitcoins in the Deferred Procrastination shop. While I’ve been following the ups and downs of the Bitcoin economy, the relative stability of the Pound to Bitcoin...
Seat Shape
This post is a bit of a development of design ideas. Sometimes it’s good to go through each stage of a design and explain why it has been rejected. Of course, like any design process there’s a good deal of opinion, approximation and guesswork to it, so be sure to...
Cockpit Clearances
Designing a cockpit to accommodate a range of rider sizes is more complex than laying out the controls to fit one rider; especially having a steering wheel control for such a reclined operator instead of underseat/tiller steering or a moveable yoke. Rider Clearances To account for different height riders while...
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,...
Ce n’pas une entrée de blog
It’s crunch time for thesis revisions this week, so there’ll be no blog post. Except this one. Which isn’t one. Back next week. As in: The Treachery of Images
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...
add-rel-lightbox now using Simple HTML DOM
When I first mashed together add-rel-lightbox, I used regular expressions to control and replace the relevent parts. This was my fault. Regexes were the only tool I had. It was a bad thing. Parsing HTML with regex is wrong. […]using regex to parse HTML has doomed humanity to an eternity...
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...
Making it Better—Open Source CNC
CNC routers and laser cutters are now common machines. Not ubiquitous, like a hammer, but they are common enough that I can send a pattern for cutting, or visit a lab and operate one myself. However, they still remain expensive, industrial machines. Makerslide took the idea of a standard aluminium...
LaTeX-SVG-to-PDF as git submodule
[mathjax] I’ve mentioned previously that I’ve got a large project in (\LaTeX) and while I was using Dropbox as a pseudo revision control and external backup. However, I’ve since been persuaded that a proper revision control system with meaningful commit message is a better way of tracking progress and changes....
