Just when you think you found a great gadget gift for your brainy dad, he offers some reasonable explanation why people shouldn't use that type of gadget or goes into a logical tirade about wasting money. You've got to find a way to get one over on a brainy dad with a gift that will challenge his intellect and make you look just as smart.

Compass
Dads never like to lose their way. It's hard to argue with a compass in the pocket for anyone, smart or not. RedEnvelope has a high-tech compass that a brainy dad is sure to appreciate (see Resources). The compass is encased in a stainless steel case that resembles a pocket watch. Get the case engraved to remind dad that you too can help to show him the way..
Organizers
Smart dads usually like to keep their belongings organized. Look for unique organizers in which he can keep his pocket change and keys. Many organizers come with electrical connections where dad can plug in his phone or other devices in the same place he also keeps his wallet. Organizers are made to sit on top of a dresser, in a drawer or near the front door. Some organizers have lids into which you can place your picture so he'll remember who is helping him keep it all together. Consider an organizer dad can keep at the office to keep his pens, paper clips, slide rules and other brainiac tools.
Carry-alls
Members of MENSA, the organization for those with high intelligence quotients, recommend carrying cases for brainy folks who require access to books, electronics, tickets, guide books and other gear. Backpacks with compartments make great gifts for brainy dads who like to carry all their geek gear everywhere they go. Laptop bags and briefcases come in a variety of shapes and sizes to fit all kinds of budgets.

Games
Brainy games can be shared with your dad when you give him a teaser such as Zenith or Scrabble. Battleship is a game many brainy dads enjoyed as brainy kids and may appreciate seeing again. Hasbro even produces a pocket Battleship game dad can take with him. Most smart dads play chess and appreciate a new board and pieces that are unique or hand-carved. Order dad the MENSA Home Test for fun to see if he qualifies for the groups choosing. You can also have these cuff links monogrammed with his initial.
