Solder kit from the "PERSOL" series from SOL-EXPERT – with a 5-star concept For perfect soldering and assembly success – for beginners and professionals alike. Build this soldering kit and create a fantastic electronic dice. Thanks to the detailed colour instructions and the included bending aid for resistors and diodes, the "Electronic dice" soldering kit is ideal for beginners, entry-level users and advanced users. A commercially available 9 V battery (not included) is used as the power supply. When the start button is pressed, the soldered IC generates a random number between one and six and outputs this value on the seven large red 5-mm LEDs. The "electronic dice" therefore replaces a conventional dice, is modern and will not fall on the floor when playing, something older or enthusiastic players are sure to appreciate.
