Next solder in:
Five
10μF electrolytic capacitors
(
watch out, these ones are polarized!
There is a plus (+) sign on the PCB that
should match the longer lead of the
capacitor)
One
2N3904 transistor
(flat side
of transistor must match the outline drawn
on the PCB!),
One
20MHz resonator
(the
orange component with 3 leads, the
marking on board is actually wrongly signed
“16MHz”),
Two
fuses
(marked “PTC” on
board; be careful,
they look quite similiar
to capacitors
).
Now insert
ICs
into sockets (1x Atmega, 1x TL074 and 1x TL072).
Watch out for orientation!
There is
a notch on Atmega and TL074 that should match with the notch on the sockets. For TL072 is relevant
the dot on it.
