Solder the regulator in. If you placed the regulator as suggested, you shouldn't have to clip the leads as they'll be short.

The regulator uses resistors to set the adjustable output voltages. We'll now solder those in.

+

First is 11.0K '''R3''' (Brown Brown Black Red Brown) - this resistor sets the 3.3V output level.

+

Second is 6.49K '''R5''' (Blue Yellow White Brown Brown) - this resistor is the 'reference' divider for all the voltages

+

Third is 20.5K '''R4''' (Red Black Green Red Brown) - this resistor sets the 5V output voltage

+

Solder and clip the three resistors.

Now we need a way to select which resistor is connected to the regulator. For that we use a 3-way switch. The switch can only go in one way.

+

Solder in all the legs of the switch.

+

Be careful because the solder points are small and somewhat close together. Make sure you don't have a short circuit and that each point is soldered

+

Now we will put in the capacitors and LEDs for the left hand "low voltage" side.

+

First is the red indicator LED. Remember LEDs are polarized. Make sure the long lead goes into the (+) marked pad
