Completed Laser Cut Brackets

You might remember from the other week that I had designed and cut some perspex brackets as an mounting for a piece of art for an exhibition. The show is now up and open as one of the independent exhibitions that are part of the Liverpool Biennial. If you were wondering how the parts I […]

Rear Hanger Shear Strap

Using adhesive as the main joining method for the Atomic Duck requires careful design of the part interfaces. Where welding is equally as strong in all directions, adhesive performs well in compression and shear, but badly when there is tension across the joint. This is not a problem of the type of adhesive, this is […]

A001_P018_R001 Chain Cover

As the chain has been rerouted for this design revision, and now goes through the cab and luggage area, that area needs to be covered. While this could be covered with 3 interlocking panels, I don’t want to leave sharp corners in the luggage area. Instead, a single piece that uses lattice hinges to create […]

A003_R002 Seat Design

The seat structure seems to have taken the most time of all the assemblies to re-design, though it was interrupted by some thesis redrafts. It’s perhaps a measure of the amount of how much work was needed on the previous revision (A003_R001). One crucial task in the redesign was changing the cross beams from aluminium […]

add-rel-lightbox Version 0.4 Released

Upgrade from your WordPress admin panel, or download from Version 0.4 switches from identifing the link-wrapped images in a page with hacked-together regexes that just about work, to properly parsed HTML structure using PHP Simple HTML DOM Parser. When I initially tried to release version 0.4 and installed the updated plugin on this site, […]

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 add a comment below if […]

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. To account for different height riders while still keeping the rider’s eyeline above the […]

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

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 of dread torture and security […]

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 […]
