This project requires some electrical componentes(capacitators, resistors, integrated circuits ...) Here I gonna put the list of components that I used to complete it(You can find all this components in pages like aliexpress or ebay):
- 1x CD4093 NAND IC
- 1x MCP602 OpAmp
- 2x 100pF Capacitator
- 1x 1nF(1000pf) Capacitor
- 1x 4.7µF Capacitor
- 6x 10k Resistor
- 1x 5.1k Resistor
- 1x 6.8k Resistor
- 2x 10k Potentiometer
- 1x Antenna
- 1x Power Jack
- 1x Audio Jack
- Printed circuit board
- Housing(Also you can use a 3D printer)
Optional(Personal Recommendation):
(Only in you want to do a previous circuit to test it)
To test the connections before soldering the circuit we use a protoboard, the wires connection in the pics cal look little caotic (because I also used this project to teach my gf about circuits and how to use the protoboard) but it's not difficult to replicate it.
This is the circuit diagram:
Final Protoboard Result:
Sound test:
Now it's time to take our tin soldering iron and the printed circuit boards and start soldering the ciruit. Take care with the potenciometers, it can be difficult to weld for starters.
