3D-printed gramophone-style amplifier gives your Echo Dot a vintage overhaul

There is something kind of steampunk about tech that brings together old and new worlds. Clearly, we’re not the only ones who are suckers for this type of thing, either, since Florida-based “maker” Bard Fleistad recently debuted a popular new retro-styled Amazon Echo accessory on Thingiverse. And it can be yours provided you have access to a 3D printer.

Called the Gramazon (you know, like a combination of “gramophone” and “Amazon”), it’s an acoustic amplifier designed for Amazon’s Echo Dot. It works on the same principle as old gramophones, with a horn attachment which amplifies the sound of your miniature smart Alexa speaker.

“The speaker is based on the old radio horn speakers from the early 20th century,” Fleistad told Digital Trends. “I’ve always been fascinated by the sleek and elegant design of these speakers, and regarded them as pieces of functional art. Over the years, it became a goal for me to obtain one of these, and if needed, restore it to working order. However, like so many other items from this bygone era, they have become fairly hard to come by these days, and the ones you do find usually fetch fairly high prices. Justifying spending hundreds of dollars on obtaining one was not something I was able to do, so I eventually gave up on the idea.”

Or, at least, it was something he gave up on until he got into 3D printing in 2017. Sitting on YouTube one evening this winter, Fleistad said that a video of a radio horn speaker popped up in his “suggested videos” feed. “I had one of those ‘Hey, I have a 3D printer, I can make that now!’ moments, and began sketching out some ideas for a homemade Bluetooth speaker,” he said. “During the process of modeling the horn itself, I happened to glance over at my Echo Dot sitting at the corner of my desk, and had another one of those lightbulb moments. Rather than sourcing a Bluetooth receiver and other hardware, I figured I could simply attach the horn to the Echo.”

Fleistad printed his finished piece using a Monoprice Maker Select 3D printer, and quickly decided to share the instructions with the wider “maker” community to let others build their own versions.

“Taking on a printing project like this can scary if you haven’t printed anything this large before,” he said. “But when you break the project into its individual parts, it’s not that scary. It just takes time. I’d say that if you have the patience to start it, anyone can make one.”

Anti-surveillance clothing is getting cheaper, but don’t expect an invisibility cloak
Affordable shirts now claim to confuse facial recognition, although their protection depends heavily on the camera and software watching you
Chart, Plot, Adult

Anti-surveillance clothing is starting to look less like an art-school experiment and more like something you could actually wear outside. Shirts designed to confuse facial recognition systems now cost about as much as ordinary streetwear, although buying one won’t make you disappear.

The Guardian reports that designers are using face-like prints, unusual cuts and infrared lights to interfere with computer vision. These techniques target specific weaknesses, so their success depends on what happens to be watching you.

This spinning drone hides in plain sight using a visual illusion
This drone doesn't turn invisible. It tricks your brain into thinking it has.
Phantom Twist

For decades, engineers have chased the dream of an invisible drone. The usual approaches have involved transparent materials, camouflage coatings, or complex optical systems that bend light around an object. Researchers at Northwestern University decided to take a completely different route. Instead of hiding the drone itself, they chose to fool the human eye.

The result is Phantom Twist, an experimental drone that spins so rapidly it almost disappears into the background. It's not technically invisible, but to anyone watching, it looks more like a faint blur than a flying machine.

This smart knitted fabric can flip switches, count your steps, and even change shape
Grandma's knitting just entered its Iron Man era

For most of us, knitting brings to mind sweaters, scarves, and perhaps an ambitious grandmother determined to make winter more fashionable. Researchers at Harvard University, however, have a far more futuristic vision. They've transformed ordinary knitted fabric into a programmable material capable of changing shape, acting as an electrical switch, sensing movement, and potentially forming the foundation of tomorrow's wearable technology.

The research, published in Advanced Functional Materials by scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), demonstrates how machine-knitted textiles can "snap" between multiple stable shapes without relying on motors or rigid mechanical parts.
