If Star Trek taught us anything, it’s clearly that we’re not quite in the future yet. Case in point: androids are not supposed to be little flecks of printed circuits with wires and jacks sprouting off them. Androids are supposed to be gorgeous fembots in polyester kimonos with beehive hairdos, designed to do our bidding and controlled by flashing, beeping, serial number necklaces.
Not willing to wait till the 23rd century for this glorious day, [Peter Walsh] designed and built his own android amulet prop from the original series episode “I, Mudd.” There’s a clip below if you need a refresher on this particularly notable 1967 episode, but the gist is that the Enterprise crew is kidnapped by advanced yet simple-minded androids that can be defeated by liberal doses of illogic and overacting.
The androids’ amulets indicate when they BSOD by flashing and beeping. [Peter]’s amulet is a faithful reproduction done up in laser-cut acrylic with LEDs and a driver from a headphone. The leads for the amulet go to a small control box with a battery pack and the disappointing kind of Android, and a palmed microswitch allows you to indicate your current state of confusion.
You’ll be sure to be the hit of any con with this one, although how to make smoke come out of your head is left as an exercise for the reader. Or if you’d prefer a more sophisticated wearable from The Next Generation, check out this polished and professional communicator badge. Both the amulet and the communicator were entries in the Hackaday Sci-Fi contest.

We saw a huge outpouring of builds for the the Hackaday Sci-Fi Contest and it’s now time to reveal the winners. With 84 great themed projects submitted, the judges had a tough task to pull out the most impressive both in terms of creativity and execution.
Here are our four winners. Two come from the Stargate universe. One is a cuddly yet horrifying character of unknown origin but unarguably Sci-Fi. The other is the best use of a bowling ball we’ve seen so far.
The grand prize goes to [Jerome Kelty] with Animatronic Stargate Helmet. [Jerome] has built a replica prop that looks like it just came out of a Hollywood shop. It’s almost a shame that this helmet won’t be worn on film – though it certainly could be. If you remember the film and the television show, these helmets have quite a bit of articulation. The head can pan and tilt. The eyes glow, as well as have irises which expand and contract. The “wings” also open and close in a particular way.
[Jerome] built the mechanics for this helmet. He used radio control servos to move the head, with the help of some hardware from ServoCity. Most of the metalwork was built in his own shop. Everything is controlled from a standard R/C transmitter, much like the original show. [Jerome] is taking home a Rigol DS1054Z 4 Channel 50 MHz scope.
First prize goes to [Christine] with
Starfish Cat: Your Lovecraftian Furby-like Friend. Starfish Cat is one of those odd projects that finds itself right on the edge of the uncanny valley. We are equal parts intrigued and creeped out by this… thing. The bottom is all starfish, with a rubber base poured into a 3D printed mold. The top though, is more cat-like, with soft fur and ears. 5 claws hide under the fur, ready to grab you.
Starfish Cat detects body heat with 5 bottom mounted PIR sensors. The sensors are read by the particle photon which acts as its brain. When heat is detected, Starfish Cat activates its claws, and also blows or sucks air through its… uh… mouth hole. [Christine] is taking home a Monoprice Maker Select Mini 3D printer.

[Jochen Alt]’s Paul is one of the coolest robots of its type, and maybe one of the coolest robots period. Personality? Check. Omniwheels? Check. Gratuitous feats of derring-do? Check. Paul is a ball balancing robot.
Under the hood, Paul isn’t all that strange. He’s got two microcontrollers, one for taking care of the balancing and kinematics, and another that handles the LEDs, speech processor, loudspeaker, remote-control, and other frilly bits. But the mathematics! Paul is a cylinder standing up on top of a bowling ball, so the only way it can roll forwards is to lean forwards. But of course, it can’t lean too much, because it has also got to balance. It’s absolutely the least reasonable means of locomotion. We love it.
[Jochen] was nice enough to put everything up on GitHub, so you can see how it was done, even though it looks like magic. And we dare you to watch the video, embedded below, and not feel at least a pang of sympathy pain when (spoiler alert!) he falls flat on his face. Does he recover? We’d love to know!
Paul is just one of the stellar robots in the 2017 Hackaday Sci-Fi contest, so head on over there if you still don’t have your fill.

[Justin Cole] was looking for the perfect birthday gift
from for his wife. After some pondering, the answer fell from the sky in the form of a meteorite. The problem was how to present it. They don’t exactly make meteorite gift boxes, so [Justin] decided to build one of his own design. The box has a Russian space age theme reflecting the meteorite’s country of origin. The theme also made it a perfect entry for Hackaday’s Sci-Fi contest.
The gift box started life as an old steel film reel box. Some of us may still have boxes like this in our basements, protecting old 8mm family movies. [Justin] modeled the box in Solidworks, then added in his custom modifications. An angled walnut platform forms the stage. In the center of the stage is a 3D printed cone. The meteorite itself sits on a platform in the middle of the cone. A magnet keeps the iron meteorite in place.
A Neopixel ring provides indirect lighting below the meteorite. The ring is controlled by an Arduino, which also drives a couple of vibration motors. The motors create a hum in time to the changing colors of the ring. The whole package creates a neat way to present a rock from space.
We really like that [Justin] didn’t go over the top with sound effects, smoke, or bright lights. More importantly, [Justin’s] wife loved it, and couldn’t wait to share a video of the box with her friends.
It’s not to late to get in on the Hackaday Sci-Fi contest action. You have until Monday evening to enter your own creation.
It’s a good thing that a ridiculous pun and a screenprint of Jean-Luc Picard on the bottom of the board is enough to qualify for the 2017 Hackaday Sci-Fi Contest, because [bobricius]’s Python-plus-Arduino card and environmental sensor potpourri is very cool.
The PCB design itself is great. It’s got a gigantic LED array, cutout for a wrist strap, and an onboard USB plug so you can program it just by sticking it in your computer; it shows up as a USB mass storage device when you plug it in. The files that show up on the “drive” are Micropython code that you can edit, save, and then run directly on the device. You can hardly beat that for convenience.
And there’s a full complement of sensors: not one but two temperature and humidity sensors, including our recent favorite BME280, which also reads barometric pressure. (We suspect that makes it a tri-corder.) There’s a real-time clock, a buzzer, and some buttons. Want to add more sensors? I2C ports are broken out for your convenience.
Besides having Star Trek flair, this board would give the various educational platforms a run for their money: Micro:bit, we’re looking at you. Very cool indeed!
Star Trek has never let technology get in the way of a good story. Gene Roddenberry and the writers of the show thought up some amazing gadgets, from transporters to replicators to the warp core itself. Star Trek: The Next Generation brought us the iconic communicator badge. In 1987, a long-range radio device which could fit in a pin was science fiction. [Joe] is bringing these badges a bit closer to the real world with his entry in the 2017 Hackaday Sci-Fi Contest.
The first problem [Joe] dealt with was finding a radio which could run from watch batteries, and provide decently long-range operations. He chose the HopeRF RFM69HCW. Bringing fiction a bit closer to reality, this module has been used for orbital communications with low-cost satellites.
The Badge’s processor is a Teensy LC. [Joe] is rolling his own Teensy, which means using bootloader chips from PJRC, as well as the main microcontroller. Kicking the main micro into operation is where [Joe] is stuck right now. Somewhere between the breadboard and the first spin of the surface mount PCB things went a bit sideways. The oscillators are running, but there are no USB communications. [Joe] is trying another board spin. He made a few improvements and already has new boards on the way. Switching to a toaster oven or skillet paste and solder setup would definitely help him get the new badges up and running.
The 80’s were a golden age of Sci-Fi cartoons. We had Transformers, Voltron, and of course, Thundercats. The story of feline humanoids on third earth has stuck with a few hackers, including [Juan Garcia]. Juan has tunneled his fandom into something amazing – he’s built his own version of Lion-O’s iconic Sword of omens. The modeling and 3D print work are top-notch. While this sword doesn’t have the Eye of Thundera as a power source, it does have some pretty clever electronics. It’s also one of the amazing entries in this year’s Sci-Fi Contest.
[Juan] wanted to create the “sight beyond sight” effect from the TV show. He started with an MPU6050 six axis gyro + accelerometer. These chips are most often found at the heart of quadcopter controllers. An Arduino Pro Mini reads the sensor data. When the sword is lifted vertically, it turns on a row of WS2812 LEDs. The LEDs replicate the pulsing eye effect from the cartoon version of the sword.
[Juan] really made this a neat build. The whole sword is powered by an 18650 Li-Ion battery. Power control and charging circuitry are all concealed inside the 3D print. When it’s time to charge up the eye, the hilt can be unscrewed to reveal a USB charging port. Click past the break to see this hack in action!
