With this soldering kit you can build a great electronic cube. Thanks to the detailed colour instructions and the included bending aid for resistors and diodes, the "electronic cube" soldering kit is ideal for beginners, beginners and advanced students.A standard 9 V 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 outputs this value on the 7 large red 5 mm LEDs. The "electronic dice" thus replaces conventional dice, is modern and does not fall off the table when playing. Especially wild or older dice players appreciate this.Size: 40 x 60 mmDifficulty level: easy / mediumConstruction time (depending on experience): 45 - 60 minutesAge recommendation: from 10 years (only under adult supervision!)MANUALCIRCUIT DIAGRAMSoldering tips as video
