Small circuit board( preferably a circle),
8 pin IC socket,
555 timer IC,
Thin copper wire,
9 volt battery and clip,
8 LED uni-color white 2 -pin plcc tape and reel,
1 farad capacitor,
2 potentiometers 10k,
Step 2: Attach Socket
Insert socket with pin rows facing the holes. Put it in the middle as shown. Insert on the side that has no metal. Bend the tips down to keep it in place and solder each tip.
Step 3: Placing LEDs And IC
Use the sharpie to make every pair of holes to be used for LEDs as shown in the picture before. Ignore the inner marks just focus on the outer eight. Place the IC in as shown and make a mark by the dot for as a reminder. Remove IC.
Step 4: Wiring the 555 Timer
The pin nearest to the dot on the timer is pin 1 and the other pins are labeled in a counter clockwise fashion. Follow the schematic but leave the led out. It should look a similar to this.
Step 5: Battery Clip And Adjuster
As seen in the previous photos are the battery clip and the two potentiometers soldered. The battery clip positive goes to pin 8 and the negative to pin 1. Hopefully you possess similar potentiometers as in the picture. What I did was cut one of the back pins from both and soldered the other back pins together. Do not cut off the pin that is all by itself.
Step 6: Attaching The LEDs
Simply apply two small drops of solder to each pair of holes and then press the LEDs down and solder. Make sure to point the small side with the cut corner towards the center.
