Circuit board
IC1
(PIC12F1840)
IC1 socket
REG
(78L05)
Fit and solder the resistors (R1 to R17) to the circuit board telling them apart
by the coloured bands around their bodies. They can be fitted either way
around. Try not to use too much solder when soldering the resistor legs that
connect to the touch pads on the other side of the board.
2
Solder the chip socket (IC1) matching the notch in the socket to the notch on
the board.
Do not solder the chip directly to the board.
3
Solder the light (LED) putting the shorter leg into the hole with the line.
The shorter leg also has a flattened edge on the rim.
5
Solder the pushbuttons (S1 and S2) either way around.
8
Solder the regulator (REG) matching the half-circle shape of the regulator to
the half-circle shape on the board. Be careful not to mistake the transistor for
the regulator.
6
Solder the electrolytic capacitors (C2, C3 and C5) to the board putting the
shorter leg into the hole with the – sign. The shorter leg also has a stripe
on the side of the body. Solder the other capacitors (C1 and C4) either way
around.
4
Connect a battery
(9V PP3)
to the battery connectors. If
Funky Guitar
is working properly the light should flash twice.
13
Carefully bend the legs of the chip inwards a little with your fingers. Fit
the chip into its socket matching the small notch in the chip to the notch
in the socket.
12
Fit the battery connectors (BATT+ and BATT-) to the board matching
the shape to the symbol on the board (the hexagonal connector is
positive, the circular negative). Ensure the connectors are pushed fully
into the board and are at right angles to it. Solder the connectors to the
board making sure all the holes are well filled with solder.
11
BATT-
BATT+
Solder the transistor (TR1) matching the half-circle shape of the transistor to
the half-circle shape on the board.
7
Solder one end of the piece of flexible wire to the hole marked STYLUS
on the board then feed it back down the support hole. Crimp the metal
ferrule to the free end with pliers.
10
Solder the jack socket (AUDIO) to the board.
9
S1
TR1
(BC547/8/9)
S2
Ferrule
Finally connect powered speakers or headphones to the jack socket. Check
that all 12 notes of the keyboard work when touched with the stylus.
