  • Development Kits

    I mentioned a development kit in passing in last week’s post (Parts Database) alongside prototyping. I want to get the chassis designs out and available to anyone who is interested in an early build. If you’d like to use Atomic Duck as as basis for your own vehicle, or want...

  • Parts Database

    As design work continues towards a prototype, which will be simultaneously available as a development kit, the increasing number of parts is beginning to need an planned method of organisation; and one that can be used indefinitely, even as parts change and are refined. As I want to make the...

  • Choosing Open Source

    I’ve been asked a lot by friends and family about if I have patented or protected my velomobile design in some way to stop “just anyone” coming along, making a copy and selling their own; and thus (so the story goes) stealing potential sales of my product. I tend to...

  • Self-Jigging Chassis

    One of the design criteria for Atomic Duck is: to be easily manufacturable, in a workshop with minimal specialist tools. As a result, the chassis parts are made from stock aluminium tube sizes and flat sheet. But the components construction is only part of the story, an Atomic Duck also...

  • Publishing 3D models

    Just a quick one this week, and a question to how about what format you would like to see 3D CAD released in. One of my intentions for Deferred Procrastination is that developments should be released open source, it encourages further development, and means that new solutions don’t get locked...

  • Why a Velomobile? Speed

    One of the clear advantages of a velomobile over an un-faired bike is increased speed. Higher maximum and cruising speeds are possible because the faired cycle has lower drag; and drag is the enemy of speed. This means that in a velomobile (when compared to a bike): You can travel...

  • Block Chassis Layout

    After a few weeks showing some of the features of Atomic Duck, it’s definitely past time to show some progress. I’ve been designing and refining this project for a few years now, so I have a pretty good grasp on what I expect each part and assembly to look like;...

  • Duck Trunk — an Atomic Boot

    For Atomic Duck to be a useful and practical mode of transport, it needs to have space to carry luggage. Obviously, it won’t have the same carrying capacity as a bakfiets or cargobike, but it should have enough room for a couple of bags, or some shopping. While the ingenuity...

  • Going backwards

    Velomobiles go forwards really well (better than an upright bike and a recumbent!) but they aren’t well suited to going backwards. It’s a probem that comes from sharing driveline components with bicycles. Bicycles don’t have a reverse gear for the same reasons motorbikes don’t: going backwards while balancing on two...

  • TweetUpdater version 3.1 release

    A new version release for TweetUpdater, adding a new option to limit message sending based on post category and meta information. Thanks to BjornW for taking the time to add to the project. The new rcmbnt.com URL shortener gave me the impetus to add the generic YOURLS support. Although I’ve...
