Attention , this part is
polarized.
Short leg is (-) minus
D1,D2,D3,D4
D9,11,12,13,14,15,16,17,18,
19,20,21,22,23,24,25
20 x LED red
Four red LEDs are soldered to positions D1,D2,D3,D4
Attention - pay attention to the polarity (minus ) is at the top !
Attention, we use red LEDs for the De-Generator with a Plexiglas case, because these are
not so bright. R18,19,20,21 are then changed from 330 Ohm to 220 Ohm.
The LEDs on the encoders can also be omitted if desired. It is a ' CAN BE'
For the metal case ultrabright blue LEDs are used, the series resistors are changed to 390
Ohm.
Now we solder the 16 red LEDs into the positions
D9,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25
Attention - pay attention to the polarity (minus) is at the top !
