ELBOBRIK - electronic educational laboratory box for kids

Hi this is my first version of education laboratory for kids.

there is some passives and transistors + 555, NAND gates, 7 segment display, RGB led

and finally small geared motor,

Cool features:

  • For connection use female to female wires
  • Every group have access to + - or another shortcut to use just Jumper ... check on picture, it can reduce wires and simplify circuits
