My apartment corridor is dark! I need one to see the key hole!
Sketch
I wanted something that would fit on my keychain with the other keys so I designed a key flashlight.

Materials & tools
I tried to use simple materials that I already had on hand.
-
LED light
-
Copper wires / tape
-
IKEA wood piece (chopstick like)
-
Push switch
-
Battery
-
Felt protectors (for furniture)
-
Scissors
Steps
After sketching out the design, I designed the circuit and followed these steps.



The final product


Problems along the way
-
Getting the switch to work was tricky, many trials and errors were involved — next time: study all the materials thoroughly before implementing the design
-
Wiring in a neat way was tricky, I untaped and taped again at least 5 times — next time: design in more detail, where are the wires gonna go exactly
-
In the end I had to use super glue to make sure all the pieces were sturdy — make sure there is a way to lock everything together nicely e.g. using joint techniques
The rough prototype
