N\u00e1\u0161 v\u00fdvoj se pohyboval v kruhu. Nejd\u0159\u00edve jsme postavili z Lega voz\u00edtko. Rozebrali star\u00fd walkman a vyu\u017eili z n\u011bho mal\u00fd elektromotorek se skv\u011bl\u00fdmi vlastnostmi. 1,7V a odb\u011br kolem 80mA v z\u00e1t\u011b\u017ei.

Sol\u00e1rn\u00ed \u010dl\u00e1nky jsme zapojili 4 a 4 paraleln\u011b a dostali tak 2V pro voz\u00edtko.
