With the holidays right around the corner, now’s the time to hunt for that gadget for the geek in your life.

This year, consider giving a consumer electronics gift from one of these 10 tri-county companies. While not all of the gizmos are made here, the design, engineering, marketing and most of the other important parts of the business are right in our backyard.

Here’s a brief description of each company and its products, with a few quick picks that the Business Times thinks would make great stocking stuffers.

  The undeniable 800-pound gorilla of consumer electronics in the Tri-Counties is Santa Barbara-based Sonos, the maker of wireless music systems that use their own mesh network for reliable playback. Nearly a decade ago, founder John MacFarlane took the Apple approach to pricing, with systems costing upwards of $1,000. But now that the brand has gone big, systems start at $199, a price so low that even the mildly geeky gadget collector has no excuse to not own one. » Quick Pick: Sonos - Play:1, $199.

  It’s no secret that smartphone battery life sucks. Santa Barbara-based iPowerup makes phone cases with an extra battery built in to give you a boost when you run out of juice.

Yes, the gear is expensive, but it is all handcrafted by Carolyn and George Counnas and, according to audio magazines, sounds as good as stuff that costs many times more. Let’s hope the geek in your life has a large stocking. » Quick Pick: Zesto Audio Andros PS1 tube phono stage, $4,300.

  OK, Nipomo-based BakBone’s ring-like device for holding a tablet computer one handed does look a little like a baby pacifier. But it works really well, because it was designed by a emergency room doctor Paul Webber for holding iPads one-handed while dealing with patients and electronic medical records. » Quick Pick: Original BakBone, $29.95.

• BuQu Tech
