Geeks like to try out new tech, and they love gadgets, so tech gifts are often on their wish list for Christmas and other seasonal holidays. With the holidays now past, you may have some Christmas cash to spend. Lots of tech and gadget companies vying for your attention this holiday season. But many, while still great gifts, are obvious, such as smartphones, laptops, and Bluetooth earpieces. Plus, they’re often the kind of technologies that geeks prefer to choose and configure themselves.
That’s where the InfoWorld geek gadget gift guide comes in. Every year, we seek unique products that will stand out and likely delight and surprise—what you didn’t know you wanted all along. This year, our selections skew toward useful, pragmatic items, though of course with that cool factor firmly baked in.
In no particular order, here’s what we recommend you consider for your off-the-beaten-path geek gift-getting—or belated gift-giving.
RainMachine Smart Wi-Fi Irrigation Controller
Much of the United States has been in a drought, and climate change will likely lead to reduced water availability for years to come. Even if not, why waste a resource? The RainMachine Touch irrigation controller monitors the weather for your area using the federal government’s weather service, and adjusts your water usage accordingly—which means it uses less water than your “dumb” controller now does.
version can control a dozen valves, the $269 version handles 16, and the $175 handles eight. Both Touch HD models have a touchscreen so that you can also program and control them directly—perfect for your gardener’s or neighbor’s use—in addition to remote control and monitoring via mobile and the web.
By contrast, the Mini-8 requires a mobile device or browser to program and monitor, though it does let you turn each valve on or off manually directly from its face. (The Mini-8 model is being upgraded to a more powerful Wi-Fi radio, so it may not be available quite yet.)
iCodis CB-100W Mobile Projector
With this device, you can take the show on the road—or trail, hotel room, campground, or anywhere else with a flat surface to project on. The tiny, lightweight pico projector (1.7 inches, 3.8 ounces) projects the screen from your computer or mobile device onto anything.
supports both the AirPlay and Miracast protocols for wireless transmission, so it’s compatible with Macs and iOS devices, as well as with many Android and Windows devices. It also supports SD cards for playback.
Multi USB Cable
It seems as if tech vendors are never happy with their cables, changing their connection standards every few years. Even if you are an Apple fan who needs only Lightning charge cables, or an Android aficionado whose devices all use MicroUSB—or a new Google groupie using only its latest USB-C-equipped Pixel devices—chances are that other people you know use other types of cables.
Whether you deal with a tangle of cables for your own devices or want to be able to ensure guests can charge whatever devices they carry, get some of the $10 Chafon , which come in black and gray versions. They have a standard USB-A connector on one end and Lightning, MicroUSB, and USB-C connectors on the other end, to charge pretty much any modern mobile device. Note: These are charge-only cables, so they won’t handle data transfer such as for syncing.
Portable Valet Charger
Speaking of charging, the more devices we carry, the more devices we need charging cables for and, thus, multiport charging blocks. It can quickly get out of hand. The $99 Belkin can help if you have an Apple Watch; an Apple Watch charger stand is built into its chassis, in addition to one USB charging port for your iPhone or other device.
Sphero “Star Wars” BB-8 App-Controlled Robot
The BB-8 droid was a darling of the “Star Wars: The Force Awakens” movie. You too can have your own BB-8, controlled from your smartphone. The small toy will especially annoy or entice your cat as you maneuver it around your house. Sphero’s toy costs $200.
“Star Wars” R2-D2 Coffee Press
Another “Star Wars”-inspired item hearkens to the original movie, featuring the R2-D2 bot (back when a bot was a very different thing than today). That’s the $40 , a French press that makes up to four cups of coffee—that’s two mugs for most of us. The R2-D2 coffee press won’t ship until mid-December, but it’s available now for pre-order.
“Star Trek TNG” Comm Badge
Last year, we recommended the $150 , a Bluetooth device that lets you talk with and listen to your smartphone from the communicator device, as if you were Captain Kirk.
This year, FameTek has created a similar product based on the “Star Trek: The Next Generation” pinned-to-the-shirt comm badge design. The $80 too becomes your smartphone’s microphone and speaker via Bluetooth, but it lets you act as if you’re Captain Picard, Captain Janeway, or Captain Sisko. It’s currently available for pre-order, with delivery expected in February for those who didn’t order the Christmas batch before Nov. 9.
USB-charging and night-light wall outlets and switches
In previous geek gadget gift guides, we’ve recommended wall outlets with and wall outlets with . Adding to that collection of practical but cool tech, this year we also recommend the $19 , which lets you add a night light at an existing switch location—while still working as a switch—to a hallway, stairwell, or other location that doesn’t have an available wall outlet. (Yes, I have all of these in my home.)
If you rent and, thus, don’t want to replace wall outlets and switches, we suggest you consider the $15 outlet cover that adds a night light and $20 outlet cover that adds a USB charger port to your existing outlets. They’re both available in standard and Decora designs, as well as in several colors.
Yes, this one is weird, and we don’t expect anyone to really use it to tell time. But the $135 from Basbrun does make an interesting, dynamic, Mondrian-style sculpture that a mathematical geek could also use to tell the time, which involves knowing the numeric values of different colors and what squares to add up to calculate the time based on their colors. Yes, Fibonacci sequences mean that you can tell time only in five-minute increments.
Oh, if you are a DIY math geek, Basbrun also sells the Fibonacci Clock as a kit.
