Hey! Can I use a ceramic capacitor instead of the tantalum one? and is there a replacement to the 150 ohm resistor? That's a bit hard to find
thanks! Could you possibly share a link that explains the functioning of the circuit and why certain components are there for specific reasons? Also do I have to use a 7805 regulator and a tantalum capacitors? I mean can I use say a LM117 regulator and an electrolytic capacitor?
