Art car 2


Here is some progress on the rocket engine for my rocket car. The top part is the combustion chamber and the fire comes out the bottom.

The plan is to have an adjustable fuel/air mix to find the maximum flame effect. Oh, and attach this to a moving vehicle.

Enjoy this tiny video of the flame effect.

Art car 1

I'm working on an art car. It is hard to describe what it looks like so I'll post some pictures. In the end this will be a flame spitting rocket ship.

powercube engine 2

We are dry fitting the engine, tanks and pump. The plates have been drilled and fitted.


Grant is tack welding on the pump mounting plate. 


The engine and pump mount plates are tacked together. Now they're ready for finish welding which will solidify the four pieces of metal.


Here you can also see the tanks sort of fitting into the frame. We still need to re-check them for leaks and attach them to the frame.

These tanks are really hard to move on their own due to their weight. When combined with the frame it is no longer feasible to lift by hand. I think we're going to have to build a hoist, which we'll need later anyway to attach the Powercube to the Artcar.

powercube tanks 4 and engine 1

Yesterday we made some really good progress. Tanks were tested. We cut the shaft on the engine. Bolt holes appeared in a new engine mounting plate. It was a really good time.

We used a rag with ice water to keep the shaft cool while cutting it with a portable bandsaw. 

we cut the shaft down by an inch (or so)
Next we'll be cutting and welding on the mount plates and tanks and looking for a shaft coupler. I believe the measurements were 1-1/8" engine side and 3/4" pump side.

the engine, frame and tanks came together and apart once again

My first Pull Request

After using open source software for a long time, I have finally found a way that I can contribute back to the community. Enter the OpenROV. I've been working on this project with a group of friends and some aspects of the software were bothering me. The software side is hosted on GitHub which makes it easy to contribute to (as well as easy to manage).

https://github.com/OpenROV

My first (public) pull request is a few small changes related to spelling corrections that were bothering me in the UI.

https://github.com/OpenROV/openrov-software/pull/238

The request was accepted and merged into the OpenROV trunk! That is good news, it means my patches were accepted into the main codebase.

I'm tinkering with a Linux kernel module at the moment and if I can find the time I will also try to send up a pull request to raspbian to include it.
