    Step 1: Communicate to share our minds, find some ideas and decide the final project.

    We talked about how type of project we want to invest ourselves, and the idea of doing something in the fantastic domain came naturally. So we though about doing an iconic thing from a Marvel's movie, and that's how we decide to reproduce the Thor's hammer in our way.

    Why you see here is our prototype. It is made of cardboard and shows the led's positions. However, we realised that it was not possible to put some on the smaller surfaces (those below the picture), as we want this part to move. Indeed, the main goal of our project is to have 2 capacities: being able to light progressively once it had been hit, and make a thunder sound. So capt this information, we thought about a moving part (with strings) that would touch a capacitive sensor.

    Finally:

    So basically our idea for this part of the hammer is to make a push-in/push-up system to activate the capacitive sensor when the side is gonna touch a face. It gonna work with 2 planks. The first one is going to be the wood plank that is the actual side of the hammer, and the second one is going to be a shift wood plank. So the two have a little space between each other but are still related by strings, and here is where our push-in/push-up system is gonna works. Also between these planks, we are gonna put a little ball made of aluminium and of balloon to make the touch connection with the capacitive sensor.

    Step 2: The choice of materials and sketches

    - The frame: We were advised not to print the hole hammer with the 3D machine. That is why we decided to print only the frame/armature. We use the software Fusion 360 to make the shape of our armature, to after print it in 3d with Cura. But our armature was only made of surfaces, so before implementing it in Cura, we had to give them some volume. We started to make it parts by parts, but we encounter a problem for the bevels because we cannot just give them volume with the tool “Extrusion”. So to solve it, we had to select the entire body and make it volumic, and it worked !

    - The faces: As just said, we decided to create some part by 3D printing, and others by laser cutting. That is why we decided to laser cut wood for the faces. 

    - The plexiglass: We asked Capucine for an led stick in order to choose the right blue and the right transparency. We choose the one on the right, as it had an opaque blue. The point was to represent lighting as much as possible and to cover the led's. So to light, without showing it was fake.

    Step 3: Building each part

    - the frame: Here are the changes that we made to limit as much as possible the printing time. We put an infill density of 20% in order to be as strong as possible, as the point of the hammer is to hit things.

    We choose the colour white as it could be easier to cover. The pictures are all below.

    - the faces: We decided to cut some wood to the perfect sizes lacking on the hammer. To do so, we used the function "projection" on fusion on our frame.

    Inside the faces we cut some bands of the size of our led's to be filled by plexiglass (see below).

    - The plexiglass: To create the "lighting effect", we thought about band that could propagate light. That is why we cut the plexiglass bands the same size as the holes wood bands.
