- The 10uF electrolytic capacitor (C2 designation)
has one of the leads
marked with a white stripe on the capacitor case. As for most
electrolytic capacitors, this marking indicates the NEGATIVE lead.
- I provided a substitute for the 1N4148 diode.
This diode has a
black case with a blue band marking the cathode. Make sure to align
the cathode (blue band) with the marking on the PCB.
- When I ordered the parts from Digikey, I did not
order enough 1uF
ceramic capacitors. So I had to replace one of the 2 capacitors with a
0.1uF. Please use the 1uF capacitor (component marking is 105) in
designation C3
and use the 0.1uF capacitor (marking is 104) in designation C1.
