- Page 2 1. Description: The Vibrating LED Dice kit works based on a vibrator switch that allows the IC chip to use its logic to toggle through different dice combinations while the device is held upside down (when the LEDs are facing down). Once the device is turned around, a randomly picked dice combination is represented by the LEDs.

- Page 4 4. Assembly: 1) In order to assemble the module, you need the following tools: *It is recommended to have some isopropyl alcohol and a fine soldering brush handy to clean off the excess flux on the circuit board when done soldering. *ATTENTION* DO NOT USE RUBBING ALCOHOL, IT WILL DAMAGE THE COMPONENTS.
- Page 5 5) Prepare your soldering tools. Use an appropriate tip for the application. Also, make sure the soldering tip is clean. Gently use a brass wool or a brush to clean the tip when needed. Another way of cleaning the soldering tip is to use a wet sponge. The soldering iron temperature depends on the type of solder used.
- Page 6 8) Place the resistor, transistor and the vibrator switch on the board and solder them. You can solder them one by one or all together.
- Page 7 9) Insert the LEDs from the opposite side (shown in the picture on the next page) and solder them. Pay attention to the polarity of the LEDs. The square-shaped pads indicate the anode (+) which is the longer lead and the shorter lead is the cathode (-). Cut the leads once they are soldered.
- Page 8 11) Remove the protective sticker from the acrylic cover and use the provided nuts and bolts to hold it down onto the board. 12) You have assembled your dice kit. Now, insert the batteries and turn the dice ON. For more Educational D.I.Y. Kits visit https://abra-electronics.com/educational-kits-trainers/...
