Operates with 9V battery, 12V car battery, four 1.5V batteries, or via one of our battery simulator kits. The alternative uses are endless. It’s designed for the beginner as well as the expert. Please drop us a line at and let us know the creative ways you and your friends use the dual DICER!


Do It Yourself (DIY) and enjoy your kit!






DICER-D6 is our automatic DUAL LED-DICE kit. It's based on “dual counters.” Using the 4093 (Schmitt-trigger NAND gates) as a random dual clock generator, it increases the each counter randomly--therefore light arbitrarily sequences of LEDs. Since we wire pin 5 to the counter RST (reset) pin (pin 15), when the counter reaches the fifth position it automatically goes back to the first position on the next pulse. 


R14 to R21 resistors determines the LEDs brightness and limits the current flow to about 10 to 15mA when running between 9V to 12 VDC corresponding. 


R5 to R13 resistors and RN1 and RN2 resistor network (bus) determines the minimum transistor forward base-current sufficient to turn the transistor on.


At given time only one random output of the each counter (U2_Q0 to U2_Q5 & U3_Q0 to U3_Q5) is "On" ("1"):


U2_Q0 = "1" --> Transistors Q1, Q2, Q3 = "On" --> Dice = 6 (L1, L2, L3, L5, L6, L7 Light)


U2_Q1 = "1" --> Transistors Q1, Q2 = "On" --> Dice = 4 (L1, L2, L6, L7  Light)


U2_Q2 = "1" --> Transistors Q1, Q2, Q4 = "On" --> Dice = 5 (L1, L2, L4, L6, L7 Light)


U2_Q3 = "1" --> Transistor Q1 = "On" --> Dice = 1 (L4 Light)


U2_Q4 = "1" --> Transistors Q2, Q4 = "On" --> Dice = 3 (L1, L4, L7 Light)


U2_Q5 = "1" --> Transistors Q2 = "On" --> Dice = 2 (L1, L7 Light)


U3_Q0 = "1" --> Transistor Q5, Q2, Q3 = "On" --> Dice = 1 (L11 Light)


U3_Q1 = "1" --> Transistors Q7, Q5 = "On" --> Dice = 3 (L8, L11, L14 Light)


U3_Q2 = "1" --> Transistors Q7, Q8 = "On" --> Dice = 4 (L8, L9, L13, L14 Light)


U3_Q3 = "1" --> Transistors Q5, Q7, Q7 = "On" --> Dice = 5 (L8, L9, L11, L13, L14 Light)


U3_Q4 = "1" --> Transistors Q6, Q7, Q8 = "On" --> Dice = 6 (L8, L9, L10, L12, L13, L14 Light)


U3_Q5 = "1" --> Transistor Q7 = "On" --> Dice = 2 (L8, L14  Light)
