Winstone’s Status Report 04/19

After the weekly meeting with our advisor, I put my efforts into the physical construction of our project. We would need a container to hold all our electronics, including the Raspberry Pi and MPR121s, and encompass the capacitive touch sensor and numpad. This container would also be the surface that the projector would display on. I decided to use a 1/4″ MDF sheet as the base and 1/8″ MDF sheets for the sides and top projection surface. These MDF sheets can be laser cut, is very resistant to warping, and sturdy enough to hold its shape and contain all our components. I spent time drawing out the cuts using a CAD program and used the laser cutter at TechSpark to cut out the box joints. I ran into some difficulty because the 1/4″ MDF sheet did not cut easily and caught fire. I had to use a box cutter to finish the rest of the cut. I put it all together in the woodshop and it is mostly complete. I will have to laser cut holes on the top projection surface for the keypad and the capacitive touch sensor once we test all the components together.
