Lately, I've heard a lot of junk. Due to our consumerist lifestyle, we discarded equipment in good working condition to buy the latest release. Thus, we contribute more to the growth of this garbage. My intention was to recycle this type of material and inspire others to do the same.
- A reader of CD's
- A piece of cardboard 15X30 cm
- An old cd
- Reedswitch a normally open (magnetic drive key easily found in electronics stores)
- A calculator
- 2 screws with washers and nuts (optional)
- Hot glue
- A rubber band to hold money
Step 1: Separating Material
Open the reader, highlighting the optics, the engine that runs the cd and the amount of metal is in above the engine, setting the album to him. At the optics, remove the two magnets. Be careful because these two magnets are very strong and can unite, injuring the fingers or hand.
The cardboard was cut into three strips of 25 x 5 cm.
The reed switch was stuck on a small piece of cardboard, the edges with hot glue to be handled because it is very fragile.
Open the calculator and connect a wire to connect each of the SAME button and set aside.
I soldered the wires on a jumper and I fixed it so that no contact from the outside. This way when not in use, simply unplug the wires.
