Daring Fireball: The IPad Magic Keyboard

De CidesaWiki

I drew a rectangle across the Pi to find out the dimensions and shape of the bottom, then added a radius to every nook using the Create Rounded Nook software. Finally, I made a copy of the base with added holes for ventilation, to make the wet wipe canister lid of the enclosure. In this post, we'll design several variations of the living hinge inside DesignSpark Mechanical (herein known as DSM), earlier than making a simple case enclosure for the Raspberry Pi.


With these take a look at cuts in mind, I set about modelling the Raspberry Pi enclosure, beginning by downloading a 3D mannequin of the Pi from the RS components library, accessible by way of the interface within DSM or the RS webpage itself. I could then copy the locating holes in the base, to add corresponding tabs to the wall elements.


Next, rotating every wall half by 90 levels, I used the 3D Pi model with the Combine instrument to chop holes in every wall, for the ports and connectors on the Pi. I used the Pull software to increase the dimensions of the base accordingly. Next, I drew rectangles on every facet of the base - the beginnings of the wall section. Following this, I drew a sequence of 6mm x 3mm rectangles round the bottom, that will act as locating holes for the wall section. Returning to the base, I again used the Pi mannequin so as to add the mounting holes, earlier than adding 4 further holes for screws and spacers that may hold your complete meeting collectively. This allowed me so as to add extra length between every wall for the corners, earlier than adding in the traces to create the hinges.


This allowed me to work from a known model, saving time quite than drawing the Pi myself. Taking word of the work within the above hyperlinks, I selected to attempt a number of different approaches to the design of the hinges: parallel traces, similar to those that seem to make up the design of the Snijlab notepad cover, and parallel rectangles, much like those detailed in the 2 links above.


I first got here across this technique with Snijlab laser cut notepad cover, and have since employed it with good impact in a number of projects. Making these modifications was a fast and easy task, and provided that the laser cutter was shut at hand, fixing these problems in the design and re-reducing took a matter of minutes. Additionally it is a popular material for DIY electronics tasks, given that it laser cuts reasonably properly with aesthetically pleasing results, in a wide variety of colours and finishes.
