With this soldering kit, you can build a fantastic electronic dice. Thanks to the detailed colored instructions and the included bending aid for resistors and diodes, the "electronic dice" soldering kit is excellent for beginners, newcomers, and advanced users. A standard 9V battery (not included) serves as the power supply. When the start button is pressed, the soldered IC generates a random number between 1 and 6 and displays this value on the seven large red 5mm LEDs. The "electronic dice" thus replaces traditional dice, is modern, and won't fall off the table while playing. This is especially appreciated by enthusiastic or older players.
