CONGRATULATIONS !!! you project just give me the reason about why all the people JUST use an arduino for their projects, instead of use another mean to drive the motors. what if i cant buy an arduino? what if i like (just as you did)is how to recycle all the "trash" that you can find everywhere and pollutes the world . you gave me exactly a way to solve the problem about to control a stepper motor without an arduino (i don't hate them , but i don't want to be an "arduino-dependant " as many people that whitout it are practically lost ), and is awesome the way you did it ! as a improvement, i suggest you look for a way to make reverse ingeniering on a "useless" printer to control it and give a new use. again, CONGRATULATIONS for your proyect

soo cool device! i love how to put useful things in a minimal place as you can , and this have all of that, congratulations !!!best regards from mexico

nice costume and what a beautifull girl !

so nice , tiny and useful circuit , congratulations !

which polarity have the battery, i mean, the positive and negative where it goes ?

so nice but how can be made with analog circuitry ? maybe an opamp, transistors, etc ? could be good to make a simpler and with recycled components version ! best regards
