You will need
Material
1. circuit board
2. semiconductor
3. ceramic caacitor
4. insulated wire
5. piezo speaker
6. led light
7. battery 3V/9V and battery connection
Tools
1. UV lamp
2. NaOH = developer, NaSO4 = caustic
3. abrasive paper
4. soldering bolt, solder
5. wire cutter
6. tweezers
Create a printed circuit board
Step 1: Take a photosensitive laminated PCB card and draw or fix the PCB layout on the card. (black pen or printed transparent sheet)
Step 2: Place the board under the UV lamp for about 2 minutes or go outside and expose it to the sun (exposing time outside depends on the intensity of the sun) - Don`t leave it to long exposed!
Step 3: Put it in a bath of acid (NaOH) - Stir every 2-3 minutes!
Step 4: Take it out, clean it with water and put it in a bath of NaSO4 - Stir every 3-5 minutes!
Step 5: Take it out and clean it again with water
The chip is now ready for soldering.
Connect components with the chip
Step 1: Take the abrasive paper and sand the chip.
Step 2: Bend and shorten the edges of the semiconductor
Step 3: Connect the semiconductor onto the chip - !Watch the direction of the semiconductor!
Step 4: Add the other components (ceramic capacitor, led light, speaker, battery connection)
Step 5: Connect the battery and make noise :D
Tipp: For a louder output use a 9V battery or connect the chip to an external speaker.
