Geek Gifts, from Nixie Tubes to Tesla Coils

Nixie tube clocks, Tesla coils, binary watches and twisty cubes: nerdy gifts that speak a geek's language.

30 days to change your mind

Geek gifts are objects that speak to fans of technology and science: either they show a real physical effect, like the arcs of a Tesla coil or the glowing digits of a Nixie tube, or they carry an in-joke that only insiders get. Typical nerd gifts include Stirling engines, plasma balls, Tesla coils, Nixie clocks, binary watches and puzzle cubes.

Nerdy gifts to match their world

Retro tech

A Nixie tube is a glass tube filled with gas: when one of its digit-shaped cathodes receives a voltage, the gas glows orange around it. The Steampunk Nixie Clock ($259.99) uses six real tubes set in solid wood with metal hardware, and shows the time in 12 or 24 hour format. The Nixie Tube Lamp ($204.99) borrows the look with RGB LEDs, in six colors you switch with the buttons on its wooden case, and the Atomic Watch ($29.99) marks the hours with elements from the periodic table.

Arcs and plasma

For the geek who likes to see electricity at work. The Tesla Coil Music ($84.99) receives music over Bluetooth, and its 4-inch streaks of lightning move in time with the song. The Blue Plasma Ball (from $69.99) shows the same physics more quietly: touch the glass and a thread of blue light follows your fingers. The Mini Tesla Coil ($119.99) is a compact coil that also plays music through its arcs, a good way to explain resonance and high voltage at the dinner table.

Always fiddling with something

Some geeks think better with something between their fingers. The Inception Spinning Top ($22.99), a small metal top, spins on the desk between two tasks. The Periodic Table Rubik's Cube ($29.99) carries the symbol, atomic number and mass of the elements on its faces, and the Lego Rubik's Cube ($19.99) has faces made of studded bricks, so they can add their own compatible bricks.

Puzzles and cubes

For someone who solved the classic cube long ago. The Round Rubik's Cube ($28.99) is cylindrical: each turn distorts its silhouette, and you have to restore the shape as well as the colors. The 10x10 Rubik's Cube ($95.99) has one hundred stickers on each face, and the Rubik's Cube Treasure Box ($44.99) turns like a real 3x3 while hiding a small secret compartment (a hiding place, not a security safe).

What a geek expects from a gift

A geek spots a fake gadget fast. A good nerdy gift works in a way you can explain: a tube that glows because a gas receives a voltage, an engine that turns the heat of a wick into motion, a watch that counts in binary. For a puzzle, find out whether they already own the classic cube: if so, aim for a shape or a number of layers they haven't tried yet. For a kit, check that they enjoy soldering before you choose one that requires it.

Frequently asked questions

What are good nerdy gifts for men?

Start from what he likes to tinker with. If he loves mechanics, the Alpha Stirling Engine Generator ($78.99) shows how the heat of a wick drives pistons, a belt and discs to produce electricity. If he collects old-school hardware, the Vintage Nixie Tube Clock ($396.99) sets six IN12 tubes from the Soviet Union in a hardwood, copper and acrylic case. If he loves references, the Binary Watch ($39.99) makes him read the time in binary. These ideas work just as well for a geeky woman.

What geek gifts work on a small budget?

Puzzles and posters stay affordable. The Periodic Table Poster (from $16.99) gives each element's symbol, name and atomic number in white text on a dark background (frame not included). The Rubik's Cube Light ($28.99) lights up as you turn it and recharges over USB, cable included. The Twist Puzzle Cube ($22.99), shaped like a twisted hourglass, has no stickers: its colors are in the plastic itself.

Which geeky gifts suit a desk?

Pick something that runs on its own or that they can handle during a call. The Led Nixie Tube Clock (from $154.99) shows the time in LED-lit cubic chambers on a wooden base, with 4 or 6 tubes. The Tesla Coil Speaker ($114.99) fits a flat Tesla coil into a compact case: it lights a bulb without contact and plays music. The Sudoku Rubik's Cube ($28.99) asks you to put digits in order on every face: a sudoku in three dimensions.

What is a Nixie clock?

It's a clock that shows the time with Nixie tubes: inside each gas-filled glass tube, a digit-shaped cathode glows orange when it receives a voltage. The Nixie Tube Clock Kit DIY ($314.99) uses four IN12 tubes, and you build it yourself from diodes, transistors and wires. Other models light their tubes with RGB LEDs, like the Nixie Tube Alarm Clock ($119.99), which also shows the weather and a calendar. Check the product page to see whether a clock uses real tubes or LEDs.

What are good Christmas gifts for nerds?

At Christmas, a kit to build over the holidays keeps a nerd busy for a few evenings. The Robot Dog for Adults ($146.77) has 936 parts and, once built, moves on remote control or voice command. The DIY Stirling Engine Kit ($74.99) is screwed together part by part, then runs on the heat of its own wick. On a smaller budget, the Acoustic Levitation Kit ($24.99) floats tiny objects on ultrasonic waves once it's assembled. You'll find more in our science Christmas gifts.

Can I exchange the gift if it isn't right?

Yes. You have 30 days to change your mind, which leaves time to give the gift and see whether it earns a place on their desk. If it doesn't suit them, you can send it back within that period. There's also free shipping on orders over $59.90.
