Hacked LCD Shutter Glasses See The Light

It’s always a little sad to see a big consumer technology fail. But of course, the upside for us hacker types is that the resulting fire sale is often an excellent source for hardware that might otherwise be difficult to come by. The most recent arrival to the Island of Unwanted Consumer Tech is 3D TV. There was a brief period of time when the TV manufacturers had nearly convinced people that sitting in their living room wearing big dorky electronic glasses was a workable solution, but in the end we know how it really turned out.

Those same dorky …read more

A Unique Microphone Preamp

We live in a world in which nearly any kind of gadget or tool you can imagine is just a few clicks away. In many respects, this has helped fuel the maker culture over the last decade or so; now that people aren’t limited to the hardware that’s available locally, they’re able to create bigger and better things than ever before. But it can also have a detrimental effect. One has to question, for instance, why they should go through the trouble of building something themselves when they could buy it, often for less than the cost of the individual …read more

Fix Your Insecure Amazon Fire TV Stick

I recently spent a largely sleepless night at a hotel, and out of equal parts curiosity and boredom, decided to kill some time scanning the guest network to see what my fellow travelers might be up to. As you’d probably expect, I saw a veritable sea of Samsung and Apple devices. But buried among the seemingly endless number of smartphones charging next to their sleeping owners, I found something rather interesting. I was as picking up a number of Amazon-made devices, all of which had port 5555 open.

As a habitual Android tinkerer, this struck me as very odd. Port …read more

Only Mechanical Relays Will Do for Automated Hi-Fi Audio Source Switching

If you are a devotee of audiophile-quality analogue hi-fi, switching between sources simply can not be done through a solid-state device. Only physical switches will do because they come without the risk of extra noise or distortion that their silicon equivalents might bring.

That is the philosophy that lies behind [Skrodahl]’s relay-based audio switching board, which boasts 5 high-quality relays each handling a stereo input, with their control passed either to a rotary switch or to an ESP32 module. The ground connections on audio and switching sides are isolated from each other to avoid transient noise finding its way to …read more

Dungeons and Dragons TV Tabletop!

With little more than pen, paper, dice, and imagination, a group of friends can transport themselves to another plane for shenanigans involving dungeons and/or dragons. An avid fan of D&D and a budding woodworker, Imgurian [CapnJackHarkness] decided to build gaming table with an inlaid TV for their inaugural project.

The tabletop is a 4’x4′ sheet of plywood, reinforced from underneath and cut out to accommodate a support box for the TV. Each leg ended up being four pieces of 1’x4′ wood, laminated together with a channel cut into one for the table’s power cable. An outer ledge has dice trays …read more

Alexa Controls This Projector Thanks to ESP8266

[jfessard] doesn’t have extra-sensory perception, but does have an ESP8266. The little board seems to pop up in every hack these days. Inspired by not wanting to get up from the bean-bag chair or leave the electronics-housing cabinet wide open to use an HDMI switcher, [jfessard] hacked together an Alexa-compatible projector control via the ESP8266!

The core functionality here is the ability to turn the projector on and off, and to switch the HDMI source. [jfessard] connected the Panasonic PT-AE3000U projector to a Monoprice HDX-401TA 4×1 HDMI switcher. Tucked away in the cabinet below the projector, it is controlled using …read more

DIY Diner Booth with Cocktail Table Arcade

[Glennzo] has a house with some odd interior design choices. The most glaring one is a living room/den complete with a green Jacuzzi hot tub straight out of the 1980s. The tub really didn’t fit with [Glennzo’s] plan to use the space as a bar and game room, so out came the Sawzall and demo hammer. The tub was in its own little alcove, possibly a converted closet. [Glennzo’s] turned the space into a restaurant style booth complete with a cocktail arcade table.

The fiberglass tub was relatively easy to cut up and remove. This left the wood framed tile …read more

Dumb STB gets smart

[Vincent Deconinck] gave a fresh lease of life to an old set top box by adding a few Euro’s worth of hardware and some software smarts. The device in question is an old VOOcorder – a Cisco set-top box provided by VOO, his cable service provider in Belgium.

The VOOcorder doesn’t have any WiFi hardware or browser / app based interfaces. It’s a simple device controlled either via an IR remote or front panel buttons. [Vincent] added an ESP8266 and hooked it up to the IR receiver on the set-top box. He also set it up as an SPI slave …read more

Hackaday Prize Entry: A Modular Open-Source AV Receiver

Hi-Fi hasn’t changed much in decades. OK, we’ll concede that’s something of a controversial statement to make in that of course your home hi-fi has changed immensely over the years. Where once you might have had a turntable and a cassette deck you probably now have a streaming media player, and a surround sound processor, for example.

But it’s still safe to say that hi-fi reproduction hasn’t changed much in decades. You can still hook up the latest audio source to an amplifier and speakers made decades ago, and you’ll still enjoy great sound.

Not so though, if instead of …read more

The Raspberry Pi As An IR To WiFi Bridge

[Jason] has a Sonos home sound system, with a bunch of speakers connected via WiFi. [Jason] also has a universal remote designed and manufactured in a universe where WiFi doesn’t exist. The Sonos can not be controlled via infrared. There’s an obvious problem here, but luckily tiny Linux computers with WiFi cost $10, and IR receivers cost $2. The result is an IR to WiFi bridge to control all those ‘smart’ home audio solutions.

The only thing [Jason] needed to control his Sonos from a universal remote is an IR receiver and a Raspberry Pi Zero W. The circuit is …read more
