Eeepc bicycle mount

Step 2 Lower part, the stiff one

This was initially the only part until I realized this is a no-go. It was only good for roller skate good ways without even speed bumps. And that wasn't my intention. First I traced the outline of my eeepc on the plywood and sawed it out, worked around the edges with the file. Not notebook, but plywood edges! This part can be a bit smaller than your notebook, as it is hard to make so much room on your bike. Then I sawed two wood bricks, to screw under this plywood shelf in a way to hold it on the forwards extending pipe and not move sideways. Many bicycles has just one pipe coming vertically and then another one going to both sides. My bicycle has another one in between those two, extending the horizontal pipe more forward. Basically this shelf rests on the horizontal pipe and cannot move forward because the bricks rest against the horizontal pipe, cannot move sideways cause the bricks are on both sides of the extender pipe. To not let the shelf move down, you need to make a horizontal hole through both bricks just above the extender pipe. This hole will have the long nail through when the construction will be mounted. Be aware, that this hole is the only means of adjusting the forward angle of the shelf and later the notebook to sit comfortably to your eyes. That depends on how much you can open your notebook. The first eeepc can open up as wide as some 160 degrees, that will be how it will sit on the higher shelf. Another thing to note, the screen is not very sunlight friendly, but again, you will not look in it all the time, only occasionally.
The last thing to this step is to add the fifth metal part. It needs to be so long, to be bent around your extender pipe and come to the nail and have holes at ends for the nail to go through. So it is bent like a U and has holes. When you will attach your construction to your bike - put the shelf on your bike, so the bricks slide around the extender pipe, slide the U metal thingy from downside in between the extender pipe and wood bricks and slide the nail inside the wood bricks holes, and U thingy holes, so the nail sits over the extender pipe. Now the construction can't move anywhere and is stiffly attached to your bike. If you have your bricks longer down, you could even manage without the metal U thing, but two nails instead. Be sure to drill your bricks hole for the nail, so the nail rests against the vertical pipe, not allowing the construction to slide backwards.
