Gaming Steering Wheel - Chip & Daniel

Knolling a gaming steering wheel as an exercise to map electronics' components. Chip and Daniel mainly focused on visually organizing the flows of input and output. 

This specific kind of electronic has emphasis in both analog and digital input. Starting at the steering wheel as the user's interface, the physical input is translated from gears in the wheel to  a potentiometer (analog), and data input through several buttons (digital).  

The circular plastic component at the center of the illustration shows the layered arrangement of the button   - plastic cap -> silicone pad membrane -> copper contact pad (on board).  

A couple of components that create output are a vibrating motor at the base of the steering wheel (to emulate the idling of a car), and a spring in the wheel as a physical resistance to user input.

Lastly, the user's input travels thru the cable as data to the connector. 

Knolled Object | Blood Pressure Monitor | Albert Lui

I knolled an oldschool blood pressure monitor that I bought for 10$ at Value Village. I actually gained a deeper appreciation for this kind of tinkering exercise because I learned a lot from it. Simply from taking it apart, I learned about what the different components probably do and how they relate to each other.

For inputs, I have switches, buttons, and I guess also my pulse creating variations in the air pressure going into the device.
 
For outputs, I have the digital LCD screen and the little record printer.

I basically pieced together this thing like an information puzzle. 12 must have been the device that pumps air into the cuff because it's connected to it via air tubes/hoses. The cuff tube is also connected to 9, which must be the component that somehow measures my heart rate/blood pressure by detecting air pressure. I also figured that the printer is run by a single motor which dispenses the paper (must be a special kind of paper that gets marked when heated like receipts because I found no ink whatsoever- I actually verified this by running the tip of a hot glue gun against it).
