The Four Player Coffee Table Pong Video Game.

Step 12 Mount the power switch and battery pack.

Since this table draws very little current, you can easily power it with four AA batteries.

Infact, if you powered this with four 2500mAh rechargeable batteries and played for half an hour a day, everyday - the batteries would last you over two months!

Get your hot melt glue gun out again and glue your battery holder to the underside of the table. Make sure you put it somewhere close to the PCB because there really is no reason to have to have long wires going everywhere. (see first photo)

Then, Solder your black (negative) wire to the -ve solder pad on the PCB (see second photo)

Then solder a wire from the positive terminal of the battery pack to one side of the switch. Also, solder a wire from the middle terminal of the switch - this will end up connecting to the +ve of our PCB. (see third photo)

Next, you need to solder the other end of that wire from the middle of the switch to the +ve circuit board pad (see fourth photo)

Now you can switch the game on and off!
