Neighborhood Bulletin Boards, Circa 1982

July 27, 2026 by 8 Comments

When the Internet first started gaining mainstream popularity in the late 90s, many optimists claimed that it would bring people together by reducing barriers to communication. That ideal hasn’t exactly come to pass yet, as anyone who has been on the Nextdoor neighborhood social network can likely attest to. Before social media, neighbors weren’t completely in the dark about their local communities, though. Besides word-of-mouth communication, there were also local access channels on cable TV, which had none of the downsides of modern social media. And [Hans] is bringing this style channel back.

[Hans]’s project is called CABLE 82, a bulletin board channel that matches the style of these channels from the 1980s. There’s better technology available for these types of systems now, though, so instead of relying on something like a character generator he’s using a Raspberry Pi running custom software to produce the video feed. The Pi hosts a web server so the 4:3 video feed can be reserved for the bulletin board display, but users who have older Pis with the yellow composite video output can skip using something like an HDMI to RF converter on their period-appropriate CRT displays. The software also adds sound functionality, as these channels always had some sort of elevator music playing while they were scrolling through local community news.

For those looking to recreate some of the nostalgia of 1980s community and technology, [Hans] has made this project open source, with all of the files on a GitHub page. Part of the reason [Hans] got interested in building something like this is that he had been trying to source a CRT television for retro gaming, and wanted to reproduce more of that era than just a few video games. A channel like this would be a great addition to a complete cable TV recreation build like this one, which even includes a preview channel of everything playing.

Deltarune’s Tenna Brought To Life

June 3, 2026 by 1 Comment

For those who have never played the hit video games Undertale and Deltarune, the games are partially known for their interesting characters, many of which have eerie, surreal, and expressive designs. One of the more memorable characters from Deltarune is Tenna, a game show host of sorts whose distinguishing feature is an old television as a head, as well as a colorful suit. As a result he’s been the subject of a number of recreations by various cosplayers and makers like [BigRig Creates].

This version of the character was actually inspired by a previous build by [BunnyBii] which used an iPad as the interactive screen/face. Inside the television, though, the actual human found this to be front heavy and limiting in the ways that it could be used interactively, especially since the only way to see the outside world in this version was with a small endoscope and screen. [BigRig Creates]’s version builds on this idea but swaps out the iPad for a Raspberry Pi, allowing for much more customization, and uses a pair of Xreal glasses instead of a screen for the view of the outside world from in the television.

To get the whole costume together, the head is 3D printed with all of the electronics inside, and a game controller integrated into a handheld microphone controls the animations shown on the screen. A vibrant, custom-tailored suit with white gloves rounds out the ensemble, along with a pair of 3D-printed shoe covers since actual yellow shoes were a bit pricy. There were some interesting problems to solve along the way, specifically with regards to power management for all the electronics, but in the end it all seems to have come together quite well. [BigRig Creates] is no stranger to builds with unusual displays, though; one of our favorites was the world’s largest Nintendo 3DS.

Analog Video From An 8-Bit Microcontroller

March 21, 2026 by 24 Comments

Although the CRT has largely disappeared from our everyday lives, there was a decades-long timeframe when this was effectively the only display available. It’s an analog display for an analog world, and now that almost everything electronic is digital, these amazing pieces of technology are largely relegated to retro gaming and a few other niche uses. [Maurycy] has a unique CRT that’s small enough to fit in a handheld television, but since there aren’t analog TV stations anymore, he decided to build his own with nothing but an 8-bit microcontroller and a few other small parts.

Portable CRT TV Becomes Retro Cyberdeck

March 20, 2026 by 12 Comments

These days, it’s pretty easy to slap together a single-board computer and a cheap LCD screen to whip up a cool cyberdeck fast. But what if you wanna go more retro? [Manu] found a portable TV straight out of the original Blade Runner film, and decided this would be the perfect base for a cyberdeck rocking a whole-ass CRT screen.

The build started with a Panasonic TR-545 television. Back in the day, it took many large batteries to power this thing up—no surprise given how power hungry CRTs are. This gave [Manu] a neat opportunity to sneak all the new cyberdeck hardware into the original battery tray, including a new lithium-ion battery pack that is much more compact than the original. A Raspberry Pi 5 is running the show, computer-wise, and it’s hooked up to an HDMI RF modulator that allows the video output signal to be hooked up to the TV’s original antenna input. It’s not the cleanest way to go, but it allowed [Manu] to make the mod entirely reversible. All the new hardware slots neatly into the repurposed battery tray, and can be removed quite easily without damage to this vintage specimen. Even the keyboard fits nicely into the setup, as [Manu] was able to find a suitable 60% layout foldable unit right off the shelf.

Check out the slide deck for more details on the build, but be warned—it’s a 241 MB PDF. Bonus points if you calculate what that would cost to store on a hard drive in 1979 when the Panasonic TR-545 was on the market. We’ve seen a similar build before, too, with a classic black & white Magnavox unit. If you like squinting at a tiny blurry screen, a CRT cyberdeck is absolutely the way to go. Just be warned that the other screenwriters at your local coffee shop will be more interested in your hardware than whatever you’re actually working on. Good luck with your next pitch all the same. Video after the break.

Philco Bet The Farm On The Predicta… And Lost

February 27, 2026 by 31 Comments

Philco was a common household brand for many years. The company started in 1892, making street lights. Then they pivoted to batteries. This was big business when early radios were all battery-operated. But in the 1920s, line-powered radios threatened to shrink their customer base, so they pivoted again. This time, they started making radios. So what happened? [The Last Shift] has the story, and you can see the video below.

Philco used advanced manufacturing techniques to make radios more affordable. By 1930, they were the number one radio maker in the world. After World War II, they moved into everything electric: mostly appliances, but also the new king of the electronics market, the television.

Real LED TVs Are Finally Becoming A Thing

February 16, 2026 by 58 Comments

Once upon a time, the cathode ray tube was pretty much the only type of display you’d find in a consumer television. As the analog broadcast world shifted to digital, we saw the rise of plasma displays and LCDs, which offered greater resolution and much slimmer packaging. Then there was the so-called LED TV, confusingly named—for it was merely an LCD display with an LED backlight. The LEDs were merely lamps, with the liquid crystal doing all the work of displaying an image.

Today, however, we are seeing the rise of true LED displays. Sadly, decades of confusing marketing messages have polluted the terminology, making it a confusing space for the modern television enthusiast. Today, we’ll explore how these displays work and disambiguate what they’re being called in the marketplace.

One Hundred Years Of Telly

January 26, 2026 by 13 Comments

Today marks an auspicious anniversary which might have passed us by had it not been for [Diamond Geezer], who reminds us that it’s a hundred years since the first public demonstration of television by John Logie Baird. In a room above what is today a rather famous Italian coffee shop in London’s Soho, he had assembled a complete mechanical TV system that he demonstrated to journalists.

Television is one of those inventions that owes its genesis to more than a single person, so while Baird was by no means the only one inventing in the field, he was the first to demonstrate a working system. With mechanical scanning and just 30 lines, it’s hardly HD or 4K, but it does have the advantage of being within the reach of the constructor.

Perhaps the saddest thing about Baird and his system is that while he was able to attract the interest of the BBC in it, when the time came for dedicated transmissions at a higher resolution, his by then partly mechanical system could not compete and he faded into relative obscurity. Brits instead received EMI’s 405 line system, which persisted until the very start of the 1980s, and eventually the German PAL colour system in the late 1960s.

So head on down to Bar Italia if you can to raise a coffee to his memory, and should you wish to have a go at Baird-style TV for yourself, then you may need to print yourself a disk.
