ASSEMBLY

We will begin with the board oriented with the power switch mounting
position towards you. This is just to keep our parts locating task simple.
1. Install S1, the power switch. Solder all six leads.
2. Install R2, the larger 1K ohm 1/2 watt resistor (brown-black-red).
3. Install R5, 100 ohm resistor (brown-black-brown) .
4. Install C1, the 0.1uF ceramic capacitor (marked 104). Note that this part
looks more like a disk than the other 0.1uF Mylar capacitors.
5. Install C2, the 10uF electrolytic capacitor. Note that this part is polarity
sensitive and must be installed properly. If you put it in the wrong way, it
will overheat and self-destruct. Pay very close attention when installing all
electrolytic capacitors in this kit!
6. Install R3, one of the 30 ohm, 1 Watt resistors (brown color, marked 30
Ω
).
7. Install C6, one of the 0.1uF Mylar capacitors (marked 104).
8. Install R4, the other 30 ohm 1 Watt resistor (brown color, marked 30
9. Install C5, the other 0.1uF Mylar capacitor (marked 104).
10. Install D2, one of the 1N5408 rectifier diodes. Note the end of the
diode with the line or band. This is the cathode end. Current can only flow
into this lead, not out of it. Remember that current flows from negative to
positive. You must install all diodes in the correct orientation as indicated
for them to function as intended!
11. Install D3, a 1N5408 diode.
12. Install D4, yet another 1N5408 rectifier diode.
13. Install D5, the last of the 1N5408 rectifier diodes. Again check
orientation of all of your diodes to be sure they are installed correctly.
14. Using a scrap lead from an already installed component, install JMP1.
15. Install R1, 1K ohms (brown-black-red).
16. Locate D1. Note that LEDs only work in a single direction. If you put
this in the wrong way, you will get no light from it at all! What you need to
do is look closely at the LED and you will notice that one leg is shorter
than the other. The edge of the LED casing will also be beveled on this
side. This short leg will be mounted in the hole facing the power switch
(S1). The shorter leg and beveled edge indicate the cathode of the LED.
