Deck Construction – Part 1

To keep the center of mass low while hovering above the water surface, the deck construction should be as lightweight as possible. At the same time it is the fastening of the masts and servos with fixing points for the vertical and edge-gated fin pylons. Therefore the construction needs a certain level of mechanical stability.[…]

Nevermore Cable Spaghetti!

When wiring a 40 pin microcrontroller with all additional electronic components on breadboards we were constantly fighting not to end up in a big mess. Thanks to Dirk’s great experience after several iterations we achieved a very well working design, but loose connections became an increasing disturbance of the experimental setup. High time to tidy[…]

Flapping Fins

To balance the numerous variables that change quickly, like gusts of wind, waves, ship motion, draft, etc. we will use four active horizontal fin stabilizers. The fins are pivoted on the carbon fibre rods between central hull and side tubes. They are supposed to trim the vessels position in the water with fast reactions, before[…]

Pretentious Pipe Pimping

There is no doubt that the shiplet’s central submarine hull – a drain pipe – needs some face lifting for the next iteration of the protoype. On its topface we add another tube as a lifting body, which also hosts the carbon-fibre slats that will connect to the side tubes and mount the fin stabilizers.[…]

Shaping the Shiplet

After successful tests to control the height level and balance of o1.01 with its four ballast tanks in our test basin, the time seems right for the next iteration. To find out if the prototype can actually defy wind and waves we have to get out in open waters. The vessel has to speed through[…]

Measurement and Control

For nostalgic reasons the prototyping hobbyists decided that o1.01‘s carbonized cerebellum is an ATmega324PA 8bit microcontroller. We will use it to level and balance the platform both via ballast tanks and adjustable fin stabilizers. The fin stabilizers will be driven by servos. But to start with, we want to control the pumps and valves located[…]

Prototype Plumbing

In July 2017 after a long night full of ideas and slipslop in Berlin Tuomo and I ended up with the plan to take the SWATH design to the max and modify the concept to just a deck above the surface carried by a three-tube underwater submarine platform. The center tube would later be the[…]

Dilettante Design Deep Dive

Looking at how commercial sailing fleets have developed after the introduction of the first steam-powered ocean liners in the middle of the 19th century is quite impressive. Within a few decades and latest with the armament of the First World War the great clippers and windjammers simply just disappeared. A new fossil fuels burning technology[…]

Brainstorming in Bergen

How do you put a handle on Utopia? How should we get started with building OHANDA ONE? That was the key question we discussed within the three days workshop at PIKSEL 16 in Bergen, Norway, at the end of 2016. In the workshop we wanted to take the first steps to making our vision a[…]
