Ever wish you could enjoy modern conveniences such as YouTube in the CRT and the graphics world of the late 20th century?
[Johannes Spreitzer] accidentally found the vintage VIENNASTAR CRT (Cathode Ray Tube TV) produced by the Austrian brand Kapsh at a flea market. The history of CRT can be traced back to 1977, using only RF input. Since most TV stations nowadays mainly broadcast digitally, CRT cannot be used as a modern TV.
However, there do exist HDMI to RF transmitters, which can convert HDMI signals to RF or coaxial cable output instead of antenna signals. [Spreitzer] The next thing to do is to plug in Chromcast, which is essentially
Enter an old monitor. You can see some creepy graphics in the video below-the video samples shown fit the retro aesthetic, but I'm sure some video combinations seem inappropriate.
HDMI-to-RF adapters are easily available in hardware stores, and they allow you to project video to a specific channel on the CRT. Needless to say, they do not have the opposite effect, although there are still TVs that can only receive RF broadcasts, so there do exist TVs that are coaxial with HDMI adapters.
Once I run CTC-5,...
This is of course the first one. But the activity is not. We have seen it before.
I have done the same thing with PS3 and RCA to UHF adapter. Let the children spend the weekend.
Except for the 1990 Mitsubishi 27-inch Xbox 360, I refused to let it die because it fits all my classic game systems best (and I can fight ducks!), and it sounds great.
Around 1977, the correct way was to modify the video TV, although I don't remember how they dealt with the lack of power transformers in many portable TVs.
Don Lancaster will of course publish articles in magazines, but he must have written in his TV typewriter recipes.
I will only use the LCD monitors found in the trash today, which are getting smaller and smaller. But I’m not nostalgic for tires, and since I’m old enough to endure it once, I’m not interested in doing it again.
For the 1981 OSI Superboard, I had an extra open small monochrome display.

The best quality is to add RGB input.
Yes, although C64 was very cool at the time, I would not miss the time when the granular PAL/CVBS exceeded RF and the chroma/luminance interference at that time. There was a day when I was very happy that we now have better hardware.
In the early 90s, when I was a child, I used to buy old TVs from that era in garage sales. They usually last for 6 months to a year, and then either die or I will find a better one.
I have never been satisfied with the video quality. I want better input. Therefore, I took apart one of the TVs. I found that the tuner is its own discreet unit sealed in its own metal box. Well, there are actually 2 boxes, one is VHF and one is UHF, but VHF is obviously the owner and one is UHF. Since UHF tuning, you can turn the VHF dial to the position marked UHF.
Anyway... the tuner is connected to the main board of the TV via a thin coaxial cable and an ordinary RCA phono jack, just like a typical composite input. I couldn't actually measure the signal on that wire, but I decided to do it bravely. I unplugged the coaxial cable from the motherboard and inserted a jumper that led to my old Atari.
There is no smoke. There is no loud sound. Just a picture. A beautiful picture is clearer than anything you can get with a modulator! I used one extension cable from the tuner through the ventilation hole to connect to the outside of the TV, the other from the motherboard, and then connected them to the external input switch. I never used an RF modulator again!
Of course, I have no such voice. There are few solder wires between the tuner and the motherboard. I think these are power and audio. It may not be difficult to find the audio cables, cut them and splice them to the switch. Part of the reason I didn’t bother was because I avoided permanent modifications, not just unplugging the cord, but also because I didn’t need it. I have a car audio amplifier sold in an old garage, a self-made 12V power supply and a similar stereo system made of many speakers. I always use it to play audio.
To my surprise, when the analog was dead and the TV had inputs in addition to RF, I thought the FCC eliminated all these types of video RF transmitters.
How did HaD miss the National Review Day? I don't use TV, so it won't affect me. Do hundreds of TV stations have to change transmitter frequencies and antennas overnight? Of course it is as interesting as the historical changes of the train gauge.
> To my surprise, when the analog signal disappeared and the TV had inputs in addition to RF, I thought the FCC eliminated all these types of video RF transmitters.
You do know that the FCC controls a small part of the world, right? ;-)
Yes, but GP is still wrong, even in the United States.
We are going backwards, but not backwards!
What is GP?

Another thing I learned on Hackaday ;-)
what? I'm pretty sure that TV RF modulators are still completely legal and subject to Part 15 as before.
Of course, digital conversion means that one day they may stop producing TVs with analog tuners, and there is certainly no new TV that relies on analog tuners as the only means of input. In other words, the FCC killed 90% of the RF modulator market.
I'm pretty sure if you just want to receive signals on your old TV, they are still completely legal.
A device that receives a video signal and outputs "RF" for a TV with only a tuner is called a modulator.
I like the old CRT. This time I think of a project I did a few years ago
It has been updated a few times, but it still runs very well.
Technically speaking, CRT is a "cathode ray tube", which is a display device in old TV sets. Therefore, you are not turning the "TV Tube" into a media player, but converting a receiver (the receiver receives a modulated signal from the air or cable RF signal) or a monitor (receiving a composite SD video source). Enter the device that can accept the digital signal provided through the HDMI cable and display it on the CRT in the cabinet.
I have a recently made Panasonic CRT TV with component video input. If there is an HDMI to component video input converter, can someone guide me? Where can I buy online? I stay in Delhi, India
You can try a Raspberry Pi that supports component video output, and then play the media on the pi.
You really can't just go to any store to buy RF to HDMI.
I may have rounded it up, but it will be HDMI to VGA, VGA to composite, and composite to RF modulator. I think Startech can do all these tasks, but the price is not as cheap as ordering AliExpress or other places.
It is easier to find a cheap android set-top box with composite materials on the 3.5mm jack port and store old game controllers out of date. I connected it to the LCD composite headrest display the previous week to prevent shit and giggles, but since that is a native resolution of 320×240 and the interface is designed for 720p, it is difficult to read. But in the past, I found that some composite or component CRT TVs performed well at resolutions of 800×600 or even 1024×768, while others were very messy. The same is true for old mono TVs, some of which are very clear and some are not very much. The particle size of the phosphor is related to it.
I can stand up and watch a lower resolution video on a decent screen. I think watching a video on an ultra-low resolution screen is almost useless for the type of video I watch. I'm not sure about the chromecast controls, but if there is no acceleration control, I would become crazy. I tend to run everything at 1.75 or 2X. That was the innovation of youtube for ten years,
Even with my first 800*600 video projector, I also noticed this: I quickly got used to the quality of DVDs, and watching VHS video after that was a bit "eye-wrenching".
For low-resolution videos, or videos that may be slightly different from the old codec used, putting them on a low-resolution CRT screen will make them look better, which is a bit like "anti-aliasing".
I agree with your use of acceleration control. However, what you meet is a strange person who makes umm, errors and string fragments in some short explosions, even if there is a lot of "dead" time between 1.25 times, they are also on 1.25X Incomprehensible speech fragments.
RPi composite video output to the TV composite video through the RF modulator or through the RF modulator will be a very labor-saving way. I really like the video on eevblog....... I might try some spare equipment...
Okay, yes, I know that "not a hacker" is usually an inappropriate comment.
but…
Plug in a device with HDMI output
Into factory-made equipment designed to convert HDMI to old-fashioned analog TV signals
And plug it into an old-fashioned analog TV.
It seems to be a classic case of using consumer devices exactly as expected. Okay, so this is a combination of newcomers and old people. Few people care about it, but still... retro fashion credits are not a bad thing!
Now, if he pulls out the tuner module, inserts a pi in it, and uses the two holes on the tuner knob to expose some form of two-point Youtube navigation interface, then of course a clean 5V is installed on the TV. Power supply for Pi.
The whole process will be an independent Pi-TV, and (with the knob type interface) may be impractical, this will be a hack!
Yes, this is the result I got from it, people plugged the computer into the TV and completely fascinated the ball, but it did not cause it to only use the box specially used to plug the computer into the TV
HAXORZ!
Yes, I never thought about becoming a "non-hacker" trend, but this is actually using off-the-shelf parts for its intended purpose. From my point of view, this seems to be an anti-hacker.
Should use 555
It feels more like hackaday wrote ads for non-hackaday audiences (what percentage of HaD readers *don't* know what CRT means?). I can’t say that I recognized the author’s name before the company acquired the ownership of HaD, but every article I’ve read recently that bears the name of the salon is such rubbish, which is really disappointing.
Feed the RF from the converter into the signal booster (or two in series) to make it wireless. Usually, it allows you to transmit a distance of about 10-15 feet. Very suitable for the other end of the house or the top floor.
I personally think that fcc should open analog TV to armature radio.
Analog TV is already part of amateur broadcasting. It happens on the ham band, not on the TV broadcast band, but a simple frequency converter is enough for ordinary old-fashioned TVs to receive it.
In fact, the most popular TV rebroadcast frequency is in a part of the 70 cm band, which coincides with the frequency used by analog cable television. You only need a TV and an old analog cable box to receive this information!
I forgot exactly what the channel number is. Unfortunately, because Canadians have other services on these frequencies, American ham near the Canadian border is not allowed to be used in the lower part of the 70 cm band. :-(
—Reminder of South Park’s song "Blame Canada" —
Madder is still running PS3’s composite (RCA) output through Game Gear’s TV tuner: the picture quality is too bad!
The composite cable should come out of the edge connector of the cassette, so I don’t know if you really need a tuner to use the composite input on the Game Gear. Although I have also heard that some later products do not have composite materials, and the original Tuner cannot be used with them.
I had to play a "Schwarz-Weiss Kapsch" TV that day. The great TV can be traced back to the 70s. A great idea to "reinvigorate the past" with modern equipment. well-done.
Dr. Moddenstein used chromecast, hdmi to rca converter, and then RF modulator to do this, but then he hacked a motion sensor light to turn on the TV and run it from the phone when the signal appeared.
I didn't even know that they made HDMI to coaxial cable converters.
You should look for the screen to play Control on the CRT. Looks great on the CRT at headquarters!
