WHOOOHOOO MIDTERM SEASON!!!

So to start off this midterm I made a 2D illustration of my heart CAM!!! This illustration was OK to say the most, but it was mostly used to help me visualize my project. As I worked on low fidelity prototypes, I very quickly found out the heart and other complex shapes did not work very well at all. So I used a basic circle but I centered it not in the center of the circle to achieve the same functionality.

Then I laser cut all my pieces, a couple of support pieces, a back, two legs and obviously the CAM itself. I attached these pieces together.

 

I then hit the plasma cutter and cut out a long piece to sit on the CAM. This piece was then sanded and filed, sandblasted and finally wire-brushed to get an aesthetic. I then attached the little man on top of it.

I then attached all the pieces to the back, and assembled the back onto the legs to achieve ~~this~~

The little man goes up and down when the back is spun!

Failures:

there are a few aesthetic failures, some from laser cutting becuase I did not do a fantastic job with the tape. As well as one from the plasma cut piece that has a little notch in the bottom.

There are two design failures that I identified, one is that the cam only works in the counterclockwise direction, the other is that the legs are not attached. I tried to attach the legs but I just could not get them on.

Pricing:

This design took about 15$ of material, about 10 in wood and 5 in metal. Assuming free use of OEDK laser and plasma cutters, and about 5$ in adhesive and lubrication materials. The cost would be about 20$ without factoring in labor. Because I struggled through this it took many hours of work, we’ll round and say 15 hours at 10$/hr, for a total of 170$ for this boy.

Thanks for reading.
