The next LED over was not initially aligned as well–
this is the best that could be done by pressing it
straight down. The shadow is not centered well.
After
carefully
bending the LED to point in
the right direction, it looks much better.
Big hint:
Do not to spend more than a couple of minutes on this
step. Get the LEDs basically aligned and move along. Why?
1. It’s a shadow clock. Forming readable shadows is your top
priority. The edges of the LED spot are a secondary feature.
2. There is natural variation in both the brightness and viewing
angle of LEDs.
Tiny
variations in these can affect the spot size.
3. This is only one ring. Variation in LED position and angle will be
less noticeable once all three rings of LEDs are lit at once.

• If your projected spot of light is pushed too low, you
can push the LED back up to correct it.
• If your projected spot of light is not centered on the
gnomon, you can
bend
the LED sideways using your
fingers (if nimble) or with fine tip pliers. (See discussion in
Step 0.)
• When applying force to the LEDs, be careful to move
them in a firm, controlled manner. You are trying to bend
the metal leads of the LED, not damage the LED itself.
