Thank you for purchasing the Electronic Dice Kit
Take your soldering skills to the next level with this Electronic
Dice Kit.
Once built, you simply shake the module to generate a
random number between one a six, indicated by the LEDs
on the top!
Powered by a CR2032 battery (not included).
If this is the rst time you are getting into electronics and
handling a soldering iron, please download our Soldering
Guide from our website.

A GOOD SOLDER JOINT
The diagram here shows you a good solder joint and two
bad solder joints. A good solder joint is clean and shiny with
a “volcano” shape, which means the component’s leg is fully
soldered to the entire solder pad on the circuit board. If your
solder joint is like the one shown in the middle, it means
you have not applied enough heat to the solder pad on the
circuit board. If your solder joint looks like the one on the
right, it means the component leg was not heated enough
by your soldering iron for the solder to join properly.
RECOMMENDED TOOLS. You will need the usual Maker essentials, including a soldering iron (TS1652 Soldering Iron Kit),
solder (NS3010), and side cutters (TH1897). A third-hand PCB holder (TH1987) is also recommended to make soldering easier.

Solder components onto the top and
bottom circuit boards, then x together
with the included spacers and screws.
Pay close attention to the way some of
these components go in because some
of them only work in one direction,
including the LEDs.
INTEGRATED CIRCUIT (IC). Instead of
soldering the IC into the circuit board
we have supplied an IC socket. Solder
the IC socket into the circuit board,
then insert the IC into that socket once
all of the other soldering is complete.
Make sure the IC is inserted with the
notch in the end matching the diagram
printed on the circuit board.
ELECTROLYTIC CAPACITOR. This capacitor
(C2) needs to be inserted into the circuit
board with the longer leg going into the
circuit board marked with the + symbol.
RESISTORS. Resistors can go into the
circuit board in either direction.
The colour bands indicate the resistor
value (See parts list for the colour
bands). Make sure you insert the correct
ones into the circuit board.
MONOLYTHIC CAPACITOR.
This capacitor (C1) can be
soldered in either way.
FINAL STEP. Solder in the switch
(S1) and the battery holder (E1).
Insert a CR2032 battery and then
tightly screw the two boards
together using the supplied spacers
and screws. These need to be
tight to make electrical connection
between the two boards. Shake and
the Dice should work.
