it would be cool to be able to just take apart a calculater, an old printer or tv and have enough knoledge to turn its parts into a funtional robot. But maybe you can!! And im about to show you how, all you need are:
* some intermediate electrical engeneering knoledge, curcuits etc.
* a multimeter (an advanced electricity meter for curcuits)
* old tv,printer,electrical toy like spy gear etc.
