Knowing that CNC machining will be the manufacturing process of choice, we can proceed with 3D modeling. The associated setup costs for machined parts are quite moderate due to modern CAM programs that can automate the programming of the machines to a certain extent. CNC machined prototypes are relatively inexpensive and have a short lead time. The only viable option left that also offers a modern and robust look and feel is to machine the lid from a solid block of aluminum. Both manufacturing techniques require either expensive molds or stamping dies which are not cost effective for lower quantities. Sheet metal forming processes and any variant of casting techniques are therefore out of the question. This limits the choice of manufacturing techniques, as processes involving high tooling costs are currently not an option. The last point is especially important since we are not looking at a very high volume product design at the time of writing. This will have a direct impact on the shapes we can model into the lid and the associated costs. One of the first questions we need to answer is which material to use and how to manufacture the lid. Revision 1.0 of the webcam PCB Material and manufacturing method Of course, we have to look at both sides at the same time. Many decisions from the mechanical side have a direct influence on the electrical design and vice versa. ![]() However, that is the nature of such a project. While the title of this update is lid assembly mechanics, the line between electrical and mechanical design will get blurred quite a bit as you are about to see. Our search was successful as was the testing of the panel! Now the hard part begins: fitting everything into a system that is not only robust and functional, but also looks good. Previously, we've explored which display panels are available and which would be the best fit for our application. Welcome back to the open-source laptop project! In this update we are going to delve into the mechanical design of the laptop lid. ![]()
