Joints soldered wrong or not at all Printing this partlist and another copy of
assembly plan (left) will help for scratching out.
It happens quite often that some part is incorrectly populated.

Did you do the correctness check in the building instructions? That usually
reveals all errors like this at once.

Hmmm, a co otocenej stabilizator (taky casta chyba). Nebo muze byt jeste
neco na +5V vetvi za stabilizatorem a to se bude hledat hur. Muzes to
zjistit tak, ze ten stablik odpojis.

Tak v tom pripade si budto otocil polaritu zdroje, ale mnohem spise si
opacne zapajel tu velkou ochrannou diodu co v twisteru je. To by
vysvetlovalo ten vysoky odpor pri mereni ohmmetrem - dioda zacina
propoustet pri 0,6V

Ahoj,
asi tam mas nekde zkrat mezi +12V a GND. Jestli pouzivas napajeci zdroj s
ochranou proti zkratu, tak se to tak potom chova(zdroj prubezne vypina a
zapina a zkousi, jestli tam je nekde zkrat a kdyz jo, tak zas na chvili
vypne).
S pozdravem

The question is how many people here already know how to ride skateboard.
Otherwise they would probably learn longer than how much time they would
save.
One is for sure - this skateboard is small enough to fit even into a full tram,
bus or train. Can save considerable amount of time when used together with
public transport.
