I'll try: The tinkerer can use all skills untrained (with zero ranks) even trained only skills. The number added to this is a
 bonus that the tinkerer receives for all untrained skill checks.

I knew that: The tinkerer gains the Bardic Knowledge special ability.	

Sneak attack: same as Rogues'.  Stacks with others.	

Smoke and Mirrors:  The tinkerer can use the cantrip Prestiditation at will.	

My prediction:  If the gnome has ten minutes to prepare, a course of action can be prepared to achieve a certain goal.	
So long as the as individual follows this proscription, he gains a +1 competence bonus 
to attacks, skills, and saves

Lucky break:  The tinkerer may reroll one roll he has just made once per day.  The second result must be taken.	

Spellcasting:  The tinkerer casts spells as a wizard, but can know spells from only one of the following schools:	
illusion, abjuration, divination, necromancy, enchantment
May know universal also.
