BOTTOM BOARD
RESISTORS
Start with the bottom board parts. First of all, take your time and check the
values of all resistors
(or you can check the color codes if you are seasoned enough):
1k
(7x),
10k
(3x),
100k
(6x).
Then solder them on the bottom PCB to their spot and snip the leads close to the PCB - the joints
need to stay there, just cut off the wires (be sure to make this step on all remaining leads in the
course of this guide).
DIODE
Move to the
diode
(
1N4007
). Be careful,
diodes are polarized
! Make sure that the marking ring on
the diode body matches the marking on the circuit board
(
check out the photo below).
