Plans for an alternate method of calculating time accurate to tenth of second ? Answered

This is for a competition it can not use any electrical device and it must literally fit inside a 30cm cube but it can expand in after the starting bell.  If anybody can point me in the direction of plans or kits that would be awesome.
