Today we hurried so much to get all the CAD done so we could lazer cut the acrylic but, while we were laying out the lazer cuter drawing we realized that the parts in the echassie weren’t up to date. Were not sure what to do because it looks like the creators of the open ROV haven published the CAD files for the updated version and instead just one huge lazer cutting file. So, we cant get just the echassie, leaving us only two options ether try to slice apart the lazer cutting files or try to design our own echassie.
For the 1986 MR2 24 hours of lemons car we prepped, I did a lot of research on weak points of the 4AGE engine in the car. I decided that one of the biggest problems was oiling, both slosh in the oil pan as well as pooling in the head. Oil temperature is also always an issue. I decided to whip up a custom deep oil pan with internal swinging baffles.
I have a 2008 Tomos Streetmate moped. Great for getting around town. Like many mopeds, the tail light (and brake light) run off the unregulated voltage coming out of the alternator. This allows the lights to run even when the bike is idling (~9V), but also means that on high speed downhills the light could be seeing up to 20V. Since automotive light bulbs are designed for ~14V, it means the tail light blows out all the time. This is bad since when you are riding it is impossible to know and not having a light will make it a lot easier to get hit at night. The LED will not only be much brighter but will come on faster (~100mS) which gives other drivers just a tad more time to react before rear ending me!
Hello I am Avi Moore writing about my mini submersible summer project. The submersible is an opensource project that was developed by two people that wanted to find some gold in a cave lake, they ended up not actually finding any gold but instead found themselves developing a new piece of technology. I got the idea to build the ROV because I read about the people that developed it in Make Magazine (http://www.makershed.com) and I was inspired to make the open ROV.
