MoltenVoltage Thumb Stadium Quick Start Manual

Thumb Stadium
Thumb Stadium™ is a 2-player hand-held game kit
which features four (4) totally different games of skill.
Easy and fun to build, Thumb Stadium is sure to provide
years of entertainment while teaching you electronics!

Assembly:
The top of the circuit board looks like this:
The 1 uF capacitors are polarized, so be sure to put the longer lead in the [+] hole. Leave a little extra lead above the
circuit board so you can bend the capacitor over prior to soldering. Trim all the leads nice and short after soldering.
Trim and strip the leads from the battery pack to the desired length. Cut them so they will wrap fairly tightly around the
edge of the circuit board when the leads are soldered and the battery pack is screwed into place (about 3/4"). Be sure
to leave a little extra wire so you have some to strip, and in case you make a mistake. Once proper operation is
confirmed, remove the batteries and attach the battery holder to the circuit board using the two self-tapping screws. Put
the screws through the battery holder, then screw them into the bottom of the circuit board. Get them good and snug,
but do not over-tighten. Push the battery holder wires flat.
Here is what the finished product should look like:

Assemble the parts in the order they appear in the Parts List, above.
The chips go in the places labeled IC-1 and IC-2. Look for the rounded out bit on top
of the socket and face the sockets the same direction as indicated on the
circuit board. Put the chips in the sockets in the same direction.
Make sure you have the correct value resistors by checking the colored stripes.
The center LED has three leads and is clear plastic. Place the LED leads into the holes
of the standoff (the little black rubber spacer). Next place the LED in the circuit
board, being sure to put the flat edge of the LED facing up, as shown on the circuit
board graphic. Orient the Green and Red LEDs as shown on the PCB by aligning their
flat sides.
