Assembly photos

1. All components neatly packaged

2. Spread out in order of soldering

3. Component side of the pcb is where the fri3d logo is

   • 33 Ohm (blue body and orange,orange.black colored bands) resistor on top
   • 120 Ohm (beige body and brown, red, brown colored bands) risistor on bottom

   2 resistors soldered

4. NPN transistor 2N3904 with flat side to the left (back of noisy cricket)

5. Electrolytic capacitor (33 microFarad)
   Mind the polarity: long leg is positive, short leg is negative, white marking on the body is negative
   There are 2 holes for positive and 2 holes for negative, choose best fitting ones.

6. Pin header soldered on the bottom
   2 orientations are possible:

   • on the bottom: this results in an upright position when mounted on the fri3d2024 badge
   • at the back: this results in a front facing position when mounted on the fri3d2024 badge

7. Ready to solder the LED
   Mind the polarity: long leg is positive, short leg is negative, flat side on the body is negative

8. LED soldered
   Mind the polarity: positive (long leg) on the bottom, negative on top (short leg, flat side on the body)
