This kit is available at etsy and ebay.
This kit comes with everything needed to complete the project (shown below) including a battery.
This is a nice kit for beginners to learn to work with solder, or anyone looking to spice up a game of Monopoly...or Chess.
There is a single momentary button, when it is held, a random number will light as it would be displayed on a die.
Step 1: Installing the Trigger.
Step 2: Installing LEDs
The LEDs do have polarity, and CAN be installed wrong. If you look closely, the footprint of the LED is not a prefect circle. There is a flat side on the negative lead. You will also see the positive lead is longer. Take care to align the flat side of the diode's footprint with the flat side of the screenprinted footprint on the board. All of the LEDs do not point the same way. Check the polarity of each LED before soldering it in place.
Step 3: Power Brace
The positive side of the battery is the side with the writing, and that should face upward. The side with no writing should be touching the board it's self.
Step 4: Chip's Challenge
This chip is sensitive to which way you install it. Incorrect installation may result in a malfunction even after it is installed correctly.
In the controller, on one side there is a small circle. Make sure that circle is on the same side as the small square within the outline of the controller drawn on the board. The picture below illustrates the proper alignment. Once in place, each of the 8 pins will need soldered from the bottom of the board.
