Ideally this week we should take our existing project and polish its finish i.e. make a project enclosure. However, I do not have a project to enclose! As a result, I embarked on an exploration of my long time curious topic ‘persistence of vision’. There are many ways to illustrate the concept of persistence of vision but I chose the spirographs as the content. Why? Because they’re fun! Everybody can participate! And they have an algorithmic pattern which animate seamlessly regardless of the strobe light (as long as the pattern matches the light frequency).
BUT! The project required a lot of precision and testing so I had to save it for another time!
I then took a look around me and found empty Altoid tins and those became my focus.
If you get rainbows, you get free Altoids!
The original design (VERTICAL)
I started drilling and attaching components only to find that my breadboard cannot fit as the switches took up too much space.
The later design (HORIZONTAL)
I used the drill press to make the holes for the switches and the nibbling tool to cut the side for the power cable. Having an enclosed box makes it very easy put everything together (it just fits!).
My key learnings.
  1. The big drill bits can bend the tins
  2. The bid drill bits leave a lot of scraps on the surface
  3. Stick the wiring to the lid! Otherwise the wire will come off
  4. The object itself contains a lot of equity i.e. personality – using something familiar to people can make the thing itself more friendly
  5. Keeping some original parts make the object more familiar – i kept the inside paper of the Altoids
